Special Design Features
1-2
Modular Design
Extraordinary
Flexibility
As seen from the rear panel, perhaps the most obvious characteristic of the Nº40 is its extraordinary modularity. Both the audio
processor and the video processor are built on “card cage” designs
that maximize hardware flexibility now and in the future. While
more costly than an “everything on one board” approach, the
extensive modularity of the Nº40's design is the best and most
logical response to the rapidly-changing world of high performance
audio and video.
The state of these arts (audio and video) are moving fast, and while
we will have legacy products like traditional analog VCRs for years
to come, we must also be prepared to accommodate new products
and signal formats that we cannot predict today. With the Nº40, we
have done our best to ensure that our options are kept open for the
future.
Even today, however, we have a truly remarkable assortment of
source components that can be brought into a sophisticated home
entertainment system. Hence the need for equally remarkable input
and output capabilities, and a clear, powerful and flexible user
interface. Also needed are innovative approaches to simplifying the
experience of an admittedly complex system; and a variety of tools
to facilitate custom-installation applications that may require the
Nº40 to control other products, or for the Nº40 to be controlled by
other products.
Input/Output flexibility
The Nº40 is modular, and can accommodate many possible configurations. But in its standard configuration, we have tried to meet
the needs of perhaps 95% of the prospective owners of such a product. With
• 7 analog audio inputs (one of which is balanced)
• 13 digital audio inputs (6 RCA, 4 Toslink™, 2 AES/EBU, 1 BNC)
• 12 analog video inputs (3 composite, 6 S-video, 3 component)
• 8 main zone audio outputs (which can be configured in many
ways to suit different systems)
• 3 main zone video outputs (composite, S-video, Component/
RGBSc)
• 1 monitor video output
• 2 “RZone” output paths (assignable Remote or Record zones)
that each include composite and S-video outputs, two pairs of
Nº40 Media Console Getting Started
stereo analog outputs, a digital audio output, and a zonespecific IR input for control purposes
• 2 PHASTLink™-compatible communications ports
• 2 RS-232 communications ports
• 3 programmable DC triggers
• 1 main zone infrared input jack
Of course, an expandable, modular design does little good without
some room for expansion. So, on top of all this standard capability,
we have left several “slots” open in each processor for future applications, which may include more I/O, secure digital audio or video
interfaces, advanced video processing options, or additional DSP
resources.
Graphic user interface
The front-panel feature that tends to attract the most attention on
the Nº40 is the inclusion of a small LCD screen on the video processor. This screen can be used in several helpful ways, including the
ability to access all the setup menus and control options via our
graphic user interface. The user interface (which is also available on
the monitor output or overlaid on the main video output) makes
setting up even a complex system relatively straightforward, as it
leads you through the process in a logical manner.
1-3
This user interface is implemented in the digital video domain for
the greatest clarity and legibility, and incorporates several proprietary Mark Levinson technologies. Its hierarchical structure is
logical and easily navigated, and presented visually in a manner
that always shows you where you are in the menu system, as well as
how you got there. It is virtually impossible to get “lost” in such a
system, no matter how deeply you delve into the hierarchy.
Sound profiles
One innovation of which we are particularly proud is the notion of
a sound profile. With many years of multichannel, audio/video experience, we have an appreciation of the degree to which people
would like to have their system configured differently, based on
what they are playing.
When watching an action movie, many people like to turn up the
surround channels and subwoofer a bit to enhance the excitement;
additionally, they may require THX processing, and particular bass
management settings to suit the explosive nature of such films.
However, when the movie is over and you put on some relaxing
music, all those settings that were so perfect for the action movie
now sound quite inappropriate, if not outright dreadful.
Getting Started Mark Levinson
Sound profiles capture the many characteristics you can define for a
particular activity, and make them available at the push of a button.
In fact, you can even set up the Nº40 so that you need not even
push the button. Instead, you can associate a profile with either a
particular type of audio signal (for example, 96 kHz PCM, Dolby
Digital, etc.) or with a particular input (for example, CD, VCR,
DVD, etc.). With a little creativity, you can readily have the system
reconfigure itself on the fly, automatically. With rare exceptions, all
you or your family has to do is select the source they want, and
adjust the volume. Our sound profiles can take care of the rest.
Home automation
Of course, there are always those who want to do more. The growth
of systems like AMX®, Audioaccess®, Crestron®, Niles®, PHAST®
and others stand as testimony to the variety of needs felt by various
luxury goods customers.
The Nº40 responds to such requirements in two ways. It can control
other products in certain logical and related ways, and it allows
itself to be controlled by external home automation systems.
1-4
No-compromise Audio
With two PHASTLink™ ports, two fully bi-directional RS-232 ports,
three programmable DC triggers, and a rear panel hard-wired IR
input, the Nº40 can direct the actions of things like motorized
screens and drapes (according to the sound profile selected), and
control the operational status of associated power amplifiers. It can
also respond to external control from systems like those listed
above, or from the Microsoft Universal Plug 'N 'Play initiative.
Speaking of Microsoft, we have also created a Windows Setup
Utility for the Nº40 that is primarily for the convenience of installers. It is strictly optional, as there is nothing you can do with the
system that cannot be done without this program. However, installers will find it helpful in that it provides for off-line preconfiguration of systems and also for the backing up of system
setup data.
As befits the first multichannel, audio/video product to carry the
Mark Levinson name, the Nº40 Media Console offers no-compromise audio performance that is worthy of its heritage.
Extraordinary measures have been taken in both design and manufacturing to ensure that the sounds you enjoy from your Nº40based system will be emotionally involving and rewarding, whether
you are enjoying conventional stereo recordings or the latest multichannel blockbuster movie.
Incoming digital signals
All digital audio signals are received using Intelligent FIFO™ digital
receiver technology to reject distortion-inducing jitter and maximize the performance potential of the incoming signal.
Nº40 Media Console Getting Started
Significantly, this remarkably effective jitter-rejection circuitry is
used for all digital signals, on all paths. Remote and record zones
also benefit from the sonic improvements of the Intelligent FIFO.
Digital processing
Digital processing of the signal in the main zone is performed by
four powerful SHARC DSP chips. These DSPs perform 32-bit fixed
point processing as well as 32-bit and 40-bit floating point processing. This compares rather favorably with more conventional 24-bit
DSPs, as 32-bit parts are 256 times more accurate than 24-bit parts.
In short, the main zone has a terrific amount of DSP power at its
disposal, allowing it to easily perform all of the following simultaneously and in real time:
• Signal decoding (for example, Dolby Digital, DTS, MPEG, etc.).
• Various music and film surround modes to provide a multichannel experience from two-channel material.
• Second-level decoding like SurroundEX and DTS ES 6.1 Matrix
processing.
• Speaker crossovers and bass redirection/management.
• Post-processing (for example, the latest THX Ultra2™ algorithms).
All of this, with power left over for future applications.
Fully independent zones
One of the design criteria of the Nº40 was complete independence
of its five “zones” (that is, the main theater and as many as four
remote and/or record zones). “Independence” in this case means
“any input to any output,” or what is known technically as a “full
crosspoint switch.”
In support of this goal, each of the “RZone” (Remote or Record
Zone) audio cards has two SHARC DSP chips of its own. With this
level of processing power, it becomes possible (for example) to
select a Dolby Digital 5.1 channel signal for enjoyment in the
master bedroom, and have the signal both decoded and then downmixed to two channels for reproduction. You do not have to think
about the format of a given source – the Nº40 works everything out.
1-5
In fact, each “RZone” card is much like an entire Nº40 audio processor in microcosm, with full A/D, DSP, D/A, and volume control
capability.
Getting Started Mark Levinson
Digital to analog conversion
Digital to analog conversion is also done at an extraordinarily high
level, as you would expect. The main zone uses a special Levinsondeveloped implementation of the Analog Devices AD1853, a new
multibit Sigma/Delta converter. In fact, each of the eight main
output channels uses two fully balanced channels of these DACs, in
a dual differential configuration. The output of these DACs is then
converted from current back to a voltage by a custom-designed
Levinson I/V converter with superlative rise time and bandwidth
characteristics. This approach, normally reserved for critical
medical and scientific instrumentation, yields distortion and noise
levels that are vanishingly low.
Even the remote zones are fully 24-bit, 192 kHz capable, and will
easily surpass the main zone audio performance of any other
surround processor now on the market.
Analog volume control
1-6
Once the signal is analog, we use precision solid-state stepped
attenuators to control the volume. Having digital control over an
analog attenuator provides the best of both worlds: the convenience of comprehensive system control with the performance of
state-of-the-art analog volume.
Specifically, the volume control circuitry of the Nº40 provides 0.1
dB resolution of its volume control over an 80 dB range, and 1.0 dB
resolution over the bottom 20 dB of its range.
Significantly, the Nº40 maintains the full performance of its
remarkable DACs at all levels, something impossible with digital
volume controls.
State-of-the-art output buffer
Finally, the output buffer circuitry used in the Nº40 employs the
same topology used in the Mark Levinson Nº32 Reference Preamplifier. This circuit has proven itself both sonically transparent and
exceptionally immune to adverse interactions with interconnecting
cables and unusual input impedance characteristics of power amplifiers. While we would hope you would consider matching Mark
Levinson power amplifiers to go with your Nº40, we recognize our
responsibility to preserve your choice in the matter. Providing this
singularly robust output stage does just that, allowing the Nº40 to
make the most of whatever cables and amplifiers you elect to use.
THX Ultra2™
Processing
THX is an exclusive set of standards and technologies established
by the world-renowned film production company, Lucasfilm Ltd.
THX grew from George Lucas' personal desire to make your experience of the film sound track, in both movie theaters and in your
home theater, as faithful as possible to what the director intended.
Nº40 Media Console Getting Started
Movie sound tracks are mixed in special movie theaters called
dubbing stages, and are designed to be played back in movie
theatres with similar equipment and conditions. This same sound
track is then transferred directly onto Laserdisc, VHS tape, DVD,
etc., and is not changed for playback in a small home theater
environment.
THX engineers developed patented technologies to accurately
translate the sound from the movie theater environment into the
home, correcting the tonal and spatial errors that occur. The Nº40
adds the following THX features when a THX Cinema mode or THX
Surround EX is indicated.
Re-Equalization™
The tonal balance of a film sound track will be excessively bright
and harsh when played back over audio equipment in the home
because film sound tracks were designed to be played back in large
movie theatres using very different professional equipment. ReEqualization restores the correct tonal balance for watching a movie
sound track in a small home environment.
Timbre Matching™
The human ear changes our perception of a sound depending on
the direction from which the sound is coming. In a movie theater,
there is an array of surround speakers so that the surround information is all around you. In a home theater, you often use only two
speakers, located to the sides of your head. The Timbre Matching
feature filters the information going to the surround speakers so
that they more closely match the tonal characteristics of the sound
coming from the front speakers. This ensures seamless panning
between the front and surround speakers.
Adaptive Decorrelation™
In a movie theater, a large number of surround speakers help create
an enveloping surround sound experience, but in a home theater
there are often only two speakers. This can make the surround
speakers sound like headphones that lack spaciousness and envelopment. The surround sounds will also collapse into the closest
speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time
and phase relationship with respect to the other surround channel.
This expands the listening position and creates – with only two
speakers – the same spacious surround experience as in a movie
theater.
1-7
THX Surround EX
Dolby Digital Surround EX is a joint development of Dolby Laboratories and the THX division of Lucasfilm Ltd.
Getting Started Mark Levinson
In a movie theater, film sound tracks that have been encoded with
Dolby Digital Surround EX technology are able to reproduce an
extra channel which has been added during the mixing of the
program. This channel, called Surround Back, places sounds behind
the listener in addition to the currently available front left, front
center, front right, surround right, surround left and subwoofer
channels. This additional channel provides the opportunity for
more detailed imaging behind the listener and brings more depth,
spacious ambience and sound localization than ever before.
A list of movies created using Dolby Digital Surround EX technology can be found on the Dolby web site at www.dolby.com. A list of
available DVD software titles can be found at www.thx.com.
The Nº40 can also engage the “THX Surround EX” mode during the
playback of 5.1 channel material that is not Dolby Digital Surround
EX encoded. In this case the information delivered to the Surround
Back channel will be program dependent and may not be very
pleasing, depending on the particular sound track and you individual taste.
1-8
ASA (Advanced Speaker Array)
ASA is a proprietary THX technology which processes the sound fed
to the two surround speakers and the two back speakers to provide
the optimal surround sound experience. When you set up your
home theater system using all eight speaker outputs (Left, Center,
Right, Surround Right, Surround Back Right, Surround Back Left,
Surround Left and Subwoofer), placing the two Surround Back
speakers close together facing the front of the room will provide the
largest sweet spot. If you have to place the Surround Back speakers
apart, you will need to go to the THX Audio setup screen and
choose the setting that most closely corresponds to the speaker
spacing, which will re-optimize the surround sound-field.
ASA is used in two new modes: THX Ultra2 Cinema and THX Music
Mode.
• THX Ultra2 Cinema mode
THX Ultra2 Cinema mode plays 5.1 movies using all 8 speakers
giving you the best possible movie watching experience. In this
mode, ASA processing blends the side surround speakers and
back surround speakers providing the optimal mix of ambient
and directional surround sounds.
•THX MusicMode
For the replay of multi-channel music the THX MusicMode
should be selected. In this mode THX ASA processing is applied
to the surround channels of all 5.1 encoded music sources such
as DTS, Dolby Digital and DVD-Audio to provide a wide stable
rear soundstage.
Nº40 Media Console Getting Started
BGC (Boundary Gain Compensation)
If your chosen listening position results in most of the listeners
being close to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that the overall sound quality
“booms” too much. THX Ultra2 provides the Boundary Gain
Compensation (BGC) feature to provide an improved bass balance.
THX Ultra2™
Before any home theater component can be THX Ultra2 certified, it
must incorporate all the features above and also pass a rigorous
series of quality and performance tests. Only then can a product
feature the THX Ultra2 logo, which is your guarantee that the
Home Theatre products you purchase will give you superb performance for many years to come. THX Ultra2 requirements cover
every aspect of the product performance and operation, including
hundreds of parameters in both the digital and analog domain.
Movies which have been encoded in Dolby Digital, DTS, Dolby
ProLogic, Stereo and Mono can all benefit from activating the THX
mode. THX Cinema modes (including THX Surround EX) need not
be activated for music, movies that were made especially for television, or shows such as sports programming, talk shows, etc. This is
because they were mixed in a small room environment.

No-compromise video
You might think the foregoing discussion of audio performance
features would be a tough act to follow. In fact, in many respects we
are even more proud of our accomplishments in the Nº40 video
processor, because the entire system integrates powerful features in
a way that makes the system incredibly simple to use, by even the
most technology averse member of the family. Both the resident
videophile and the technology averse can enjoy the system equally
for what it offers.
High performance switcher
When operating as a switcher, the Nº40 offers performance comparable to the finest professional switchers that you might find in
post-production houses in Hollywood.
The key here is the video crosspoint switch (the circuitry that
allows any input to be routed to any or all outputs simultaneously).
It has video frequency response in excess of 70 MHz, with a signalto-noise ratio better than 60 dB.
Three video backplanes
The Nº40 has three separate video “backplanes.” (A “backplane” is
the circuitry that the cards of the card cage plug into, that is responsible for distributing all signals to wherever they have to go.)
1-10
Getting Started Mark Levinson
The analog backplane, as discussed, rivals the finest matrix switchers used in the professional video world.
In addition, the Nº40 has a standard definition digital video backplane, and a dedicated high definition digital video backplane. The
standard definition digital video backplane is used for routing
transcoded video signals within the Nº40 (more in a moment), and
for our digital graphic user interface. In all, there are over 2000
“nets” (connections) in the video backplanes to ensure that you can
get the signal you want to where you want it.
Tran sc odi ng
You may remember that a goal of the Nº40 was to operate with full
independence among its five zones. In the realm of video, this
requires a “Universal Translator” function that can convert between
the various video signal formats likely to be encountered, within a
given broadcast standard.
The Nº40 video processor will receive standard, interlaced composite, S-video, and component signals and transcode them to provide
all of those formats simultaneously on all zones. It will convert
signals “up” or “down” as needed to ensure that all outputs are
active, all the time, regardless of input signal. (Note, however, that
the Nº40 does not change frame rates or broadcast standards. For
example, we do not convert from 60 fps NTSC to 50 fps PAL or vice
versa.)
Also, progressive input signals cannot be routed to RZones, since
there is no definition for a progressive composite or S-video signal
format exists. If you have a progressive source, we suggest connecting both its progressive output (for use in the main zone, without
any further signal processing) and its S-video or composite output
(for use in remote or record zones). Set up two inputs, one for each
type of video, naming them something like DVD-p and DVD-i. Use
the interlaced signal in the RZones.
Thus you can make whatever connection is best for your subsequent video processing or display device, and not concern yourself
about switching between formats as you select sources – the Nº40
takes care of all that for you.
In the remote zones, the Nº40 also provides both composite and Svideo connections that are always active, even when the selected
source is a component signal.

Installation Considerations
The Nº40 Media Console requires special care during installation to
ensure optimal performance. Pay particular attention to instructions included in this section and to precautions included
throughout this owner’s manual.
Unpacking
The Nº40 Media Console is a two-component system, each dedicated to state of the art switching and processing of video and
audio, respectively. These two components are shipped in separate
boxes to avoid becoming unwieldy, but they must be used together.
They were designed as a single system.
Included with your new Nº40 are two pairs of knit, white gloves
designed to assist you in the initial unpacking and placement of
your new purchase. Please accept them as a token of our appreciation for having purchased our products.
When unpacking the Nº40:
DO save all packing materials for possible future shipping needs.
Only the original, purpose-designed shipping carton is acceptable
for return to the factory.
1-11
DO inspect the Nº40 for signs of damage during shipment. If
damage is discovered, contact an authorized Mark Levinson dealer

might cause interference.
DO NOT place either Nº40 chassis on a windowsill or in another
location in which it will be exposed to direct sunlight.
DO NOT obstruct the IR receiver/transmitter located on the right
side of the video processor front panel display. When the Nº40 is
not using the IR input connector, the remote control IR transmitter
must be in line-of-sight with the front panel display IR receiver/
transmitter for proper remote control operation. See “Remote
Control” on page 4-1 for additional information.
Warning! MAKE SURE all components are properly grounded. Do not
defeat the safety purpose of polarized or grounding-type plugs
with “ground-lifter” or “cheater” adaptors. Doing so can cause
dangerous voltages to build up between components. The presence of these voltages may result in personal injuries and/or
product damage.
Rack mounting
If your equipment is bolted into a dedicated rack, you will be glad
to know that purpose-designed rack mounting shelves are available
for your Nº40. These solidly-built shelves not only provide for the
requisite ventilation, but also for the “dressing” of the many cables
behind the system. See “Rack Mount Kit” on page A-7. Please
contact your Mark Levinson dealer for additional information.
Heat considerations
The Nº40 video processor dissipates approximately 75 watts of
energy. The Nº40 audio processor dissipates about 100 watts. It is
therefore normal and perfectly safe for them to run somewhat
warm to the touch – think of a box that had a 100 watt light bulb
running in it all the time. They will not normally become uncomfortably hot to the touch, however.
Mechanical drawings are included in this manual to facilitate
special installations where necessary (See “Nº40 Video Processor
Dimensions” on page A-5, and “Nº40 Audio Processor Dimensions”
on page A-6).

Getting Started Mark Levinson
Power Requirements
Mark Levinson products are factory-set for 100V, 120V, 220V, 230V
or 240V AC mains operation at either 50 or 60Hz, based on the
country for which they are manufactured.
If you have more than one circuit feeding the system with power,
please ask your electrician to ensure that they are all operating with
a solid, low impedance ground reference that is the same for all
products in the system.
The operating voltage of the Nº40 cannot be changed by the user,
and any attempt to do so will void the warranty. If you need to
change the operating voltage of your Nº40, or if the voltage indicated on the rear panel label is not available in your area, contact
your Mark Levinson dealer for assistance.
1-14
Break-in Period
Operating States
Although your Mark Levinson Nº40 Media Console delivers
outstanding performance straight out of the box, you should expect
to hear it continue to improve as it reaches its normal operating
temperatures and its various components “break-in.” It has been
our experience that the greatest changes occur within the first 2550 hours, but that the system will continue to improve in sound
quality for about 300 hours, after which time it remains quite
constant.
The only exception to this rule is if power is removed from the unit,
allowing it to cool down. This can occur beacause of:
• Extended power outages
• Unplugging the product from the wall during a vacation
• Using the front panel power buttons rather than one of the
standby buttons.
In these cases you should expect a brief warm-up period before the
sound quality is at its best. (Fortunately, you will never have to
repeat the full 300 hour break-in period.)
The Nº40 has three operating states:
• Off AC mains power is disconnected using the front
panel power button or by unplugging the unit
from the wall.
• Standby The Nº40 is powered up, but audio outputs are
muted and video outputs are either off or fed a
“black screen” signal (sync but not picture information).
• On Everything is powered up and outputs are active.
Nº40 Media Console Getting Started
While Reading the Manual...
The following brief introductionto the Nº40 Media Console
assumes that your installer has already programmed the system for
you. For complete information on using your Nº40 and customizing it to suit your individual preferences, please continue reading
this manual. We hope you will be able to do so while listening to
some outstanding music on your new system.
The controls you will use most often on your Nº40 Media Console
include: Input Select, Volume, Surround Mode, Profile, Zone, and
Preview.
Input Select
Turning the input select knob (or using the input select rocker
switch on the remote) cycles you forward or back through the list of
defined inputs. It does not require you to turn the knob endlessly
through a long list of connections you may not yet be using.
“Defined inputs” are ones that have been set up in the input menu.
Each input can be associated with one video connection and as
many as three audio connections.
Auto-migration
1-15
Multiple audio connections are supported for products like laserdisc
players that might require any of three different types of connection, depending on what disc is inserted into the player (for
example, AC-3 RF demodulator, digital, and analog). In such cases,
the Nº40 will automatically select the Dolby Digital (AC-3) signal if
it is available; if not, it will look for a digital PCM signal at the
appropriate connector; if there is no signal there, it will look to the
analog input you listed. No further interaction is required on your
part beyond selecting the appropriate input by name.
If multiple signals are present and you need to choose one, you can
use the direct command force migration to manually change the
source. This command must be added to the toolbar or set to one of
the “f” keys on the remote control.
Volume
Turning the volume knob (or using the volume rocker switch on
the remote) raises or lowers the volume of the system. Unlike other
systems, the Nº40 provides 0.1dB resolution from 0 to 20dB. Thereafter, it provides 1dB resolution up to 8odB, providing a full 80 dB
of volume control.
This extraordinary resolution allows you to “dial in” precisely the
desired volume, for the most realistic reproduction. When listening
to music, for example, strive to play the music at the volume you
would experience it at a live concert, when sitting in the best seat in
the house. (This assumes your amplifiers and speakers are up to the
task)
Getting Started Mark Levinson
Surround Mode
Sound Profile
Once you have selected the source and set the volume, you may
find that a different surround sound processing mode would better
complement the material you are playing. The surround mode
knob (and the surround mode rocker switch on the remote) gives
you access to all available and appropriate surround mode options,
based on the nature of the signal you have selected.
For example, a two-channel analog signal might be music, or a twochannel Dolby Pro Logic encoded movie soundtrack, or any of
several other possibilities. The Nº40 offers many options for such a
signal, all accessed by the surround mode knob (or rocker switch).
This control is context-sensitive. For example, it will not present
you with processing options designed for two-channel signals when
you are receiving a discrete multichannel soundtrack. Instead, it
will only give you processing options that make sense in the
context of the signal being received.
The Mark Levinson Nº40 Media Console introduces a new concept
to high performance home entertainment systems: The Sound
Profile. When you create a sound profile, you are in effect defining
a comprehensive system configuration that complements a particular use of the system. By selecting that sound profile, the system
will reconfigure itself “on the fly” to meet your requirements.
1-16
Imagine how you might configure the system for watching an
action movie: the surround speakers and subwoofers might be
turned up a little to make it more exciting; you might use an 80 Hz
crossover frequency in order to make the best use of your subwoofers; you might engage THX processing (since you are watching a
film); you might program one of the DC triggers to turn on, so as to
lower a projection screen for your television. Having decided what
the “ideal” setup of the system would be for such things, you could
give it a name: “Action Movie.”
Now imagine that you want to listen to some classical music. The
exaggerated bass and rear channels are inapropriate; you might
prefer a 30 Hz crossover on your front speakers (assuming they have
tighter bass than your subwoofers); a stereo surround mode makes
more sense; the DC trigger should turn off so as to rid the room of
the screen that is no longer needed. Fine: give it a name like
“Classical.”
Having created a few profiles matching your tastes in such things,
you could recall all the settings by touching the sound profile
button on the audio processor's front panel, or the profile button
on the remote control.
Alternatively, you can associate a sound profile with either a particular type of signal (like Dolby Digital 5.1), or with a particular
defined input. You can even create multiple versions of the same
input (with the only real difference being the associated profile) to
make switching between profiles on a given source component
Nº40 Media Console Getting Started
easy. You might have two defined inputs labeled “DVD-Film” and
“DVD-Music” that would automatically configure the system for
either music or movies, depending on the type of disc you put in
your DVD player.
Zone
The standard configuration of the Nº40 is as a three zone system.
This means that you can have the signals from any connected
source component sent to any of three different “zones,” in any
combination. For example, you might have: the main theater zone;
a “Record” zone used for VCRs, cassette decks, and CD-R decks; and
a “Remote” zone used to enjoy music and/or films in another part
of the house. The Nº40 Media Console supports up to five
completely independent zones (additional “RZone” cards can be
ordered at additional cost from your Mark Levinson dealer).
If you want to change what is being sent to a remote or record zone,
turn the zone knob on the front panel of the video processor to
select the zone you want to change, and then turn the input select
knob to send the desired signal to that zone. The LCD display on
the video processor will show you what you are doing as you do it.
After a short delay, the display will revert to normal and the Nº40
will default back to controlling the main (theater) zone.
You can access zone control and status from the remote control by
the right arrow navigation key if no other menus are being
displayed. This will show you a list of zones with the main zone
being highlighted. Using the down arrow you can select the other
zones and their status will be displayed. Hitting the left arrow will
then bring you to the input select menu for the highlighted zone.
1-17
Preview
You can “preview” a source without actually changing what is being
sent to any particular zone. This can be used to “cue up” a video
selection for some guests without their having to watch the cueing
process, or to assist in a simple video editing process.
To do so, press the preview button on the front panel of the video
processor. The LED indicator above the button will light up, and
the LCD display will switch to preview mode. Turning the input
select knob while in preview mode will have no effect on what is
being sent to the chosen zone. (Pressing preview while on a remote
or record zone “locks” you into preview mode on that zone to avoid
the timeout that would normally take place). Once you have found
the exact point in the video you want, pressing enter again will
extinguish the LED indicator and send the selected source to the
selected zone.

Levinson components.
When first connected to the AC mains, the audio and the video

respond to commands from remote controls or external control
systems. We suggest using Standby except perhaps on those occasions
when you will be away for an extended period of time.
Use the input select knob to select from among all the defined
inputs on the Nº40. Doing so will select both the sound and the
picture (if any) for the chosen input.
LCD display
A “defined input” is minimally a single audio connection that has
been given a name to help you select what you want, when you
want it (for example, “CD”). More often, a “defined input” will be a
combination of one video connection and as many as three audio
connections, the latter listed in a priority order. (Examples might
include “DVD” or “Laserdisc.”) You or your installer can define
inputs as you see fit in the input menu, within the setup menu.
When used in conjunction with the zone knob, the input select
knob can also be used to select the signal being sent to an “RZone”
(a Remote or Record zone). To do so, select the zone you wish to
change on the zone knob, and then select the input you wish to
send to that zone on the input select knob. The video signal you
have selected (assuming there is one) will be displayed on the front
panel LCD display for a few seconds, and then it will time-out and
return to its previous operation.
The color LCD display on the Nº40 video processor can be used in
any of several ways:
• For quick and easy access to the menu system, without having
to turn on the main video display;
• Optionally, as your sole access to the menu system (if you prefer
to not have such distractions on your main display);
Nº40 Media Console Front Panel Operation
• To “cue up” the next video source prior to sending the signal to
the main display;
• To monitor what is happening on any Remote or Record zones
(“RZones”).
The behavior of the LCD display is affected by the preference
setting found in the User options menu. See “Menu System” on
page 5-1 for more details.
Zone knob
The Nº40 Media Console is a “multi-zone” system – it can manage
several signals at once, as if it were several separate systems. This
multiplies the value of all the source components connected to the
Nº40, since they are now more widely available.
For example, you can watch television on your satellite receiver,
while copying a home video from your camcorder to a VCR, while
someone else in the study listens to music – all from the same
system. In fact, you can have as many as four remote or record
“zones” of independent operation in addition to the main zone, by
adding a few extra cards to your Nº40. Any source connected to the
system can be sent to any zone, whether for recording purposes or
enjoyment in a remote part of the house. Since any of these zones
can be used for either Recording or for Remote access to the system,
we call them “RZones.”
2-3
The zone knob controls the zone (main zone or RZone) you are
either monitoring or controlling at any point in time. By turning
the zone knob, you will call up an on-screen list of the available
zones, from which you can choose the one you wish to use. Once
selected, the audio and video signals chosen for that zone are
presented in the main room for your review and control. You can
select a different source (using the input select knob), cue up something to be recorded, or check to see what is going on in a different
zone.
If you want to see what is happening in another zone without
affecting what happens in the main room, press the preview button
before you select anything with the zone knob. This allows you to
see (though not to hear) the signal being sent to a different zone
without interrupting the music or movies playing in the main
room.
The Mark Levinson Nº40 normally includes two RZones (both
audio and video) as standard equipment, in addition to the main
room's outputs. If you would like to have additional RZones
installed, please contact your authorized Mark Levinson dealer.
Lastly, thanks to its proximity to the menu select and enter buttons
on the front panel, when in a menu the zone knob can also be used
to select from among items in a menu. Turning it moves the cursor
up or down in the list, highlighting different items in turn. You can
press menu select to cancel out of a menu item (moving back up
one level in the hierarchy), or enter to save a change or advance to
Front Panel Operation Mark Levinson
the next level. Please refer to “Menu System” on page 5-1 for more
information.

IR window
As with most contemporary electronic products, the Nº40 can be
controlled by its included infrared remote control. (See “Remote
Control” on page 4-1 for more details.) The infrared sensor is
located behind the dark window on the right side of the Nº40 video
processor.
Unlike most consumer electronics products, the Nº40 can also emit
infrared commands from this same window. This ability allows the
Nº40 to “teach” learning remote controls all of its commands,
including many special-purpose commands that are not included
in the supplied remote control. For example, all “toggle”
commands (like the “operate/standby” toggle) also have positive
control equivalents (“go to operate” and “go to standby”). You do
not generally need such commands when you are in the same room
as the system, and operating it from our remote control or the front
panel. However, their availability makes it possible for you to create
reliable macros on learning remote controls. You could (for
example) create a macro titled “CNN” to turn on the entire system,
adjust the volume, select the television tuner, and change the
channel to your favorite news station – all with a single touch of
the button. Using sound profiles, you could expand this capability
even further. (See “Advanced Features” on page 7-1, later in this
manual.)
Preview button
You can “preview” a source you are about to send to another zone,
without actually sending it there. You may want to “cue up” a
particular movie for your guests without forcing them to endure
the piracy notices or the DVD menu system. Or you may want to
“cue up” a particular segment of a home movie when readying a
tape you want to record.
To take advantage of this ability to temporarily set a signal aside:
1. Press the preview button (the LED indicator above the preview
button will light to let you know you are in preview mode).
2. Use the zone knob to select the zone you want to use.
3. Use the input select knob to select the input you want to preview.
4. Cue up your source as desired, watching it on the LCD display.
When you have everything the way you want it, press the enter
button again to send the signal to the zone you had originally indicated. Doing so will change whatever was happening in that zone
until that time.

The menu select button (and the menu button on the remote

Once you are within a menu, pressing the menu button exits the
current menu item without saving any changes. It is used with the
enter button and the navigation cluster (up/down/left/right
buttons) on the remote to move around in and change the settings
of various menus. You can also use the input and zone knobs for
navigation if you prefer. Please refer to “Menu System” on page 5-1
for more information.
The enter button (both on the front panel and on the remote
control) is used in the menu system, in one of two ways (depending
on context).
When in the menu system, a highlighted area will indicate the

Surround Mode Knob
The surround mode knob will cycle you through the applicable
surround processing options available for the input you have
selected. Turn the knob to move through your options until you
find the one you want, given the nature of the source to which you
are listening.
Note that this is signal-dependent: there are many more options for
processing a two-channel signal than there are for processing a
discrete multichannel signal. After all, many of those two-channel
options are oriented toward making the two-channel signal into a
multichannel signal; they are not needed when you have discrete
multichannel information to begin with.
Thus, when listening to a two-channel source like a CD, you have a
range of options including:
• 2-channel stereo
• Stereo Surround
•Dolby Pro Logic
• Dolby Pro Logic with THX.
When listening to a discrete multichannel signal like Dolby Digital
5.1, or DTS, your options include:
•Downmix (2-ch)
•Multichannel
• THX Cinema.
By creatively using the sound profile feature, the Nº40 will most
often be able to determine what is the “correct” surround mode for
the signal you are playing, and automatically engage it. However,
you always have the option of overriding this default setting. To do
Nº40 Media Console Front Panel Operation
this, turn the surround mode knob. For more information on sound
profiles and their use, please refer to “Advanced Features” on
page 7-1.
Alpha-Numeric
Display
Volume Knob
Sound Profile Button
The central window of the Nº40 audio processor contains two rows
of twelve alpha-numeric characters. This text-based display
provides you with information on the selected input, the type of
signal being received and/or the current surround mode, and the
current system volume.
Normally, you turn this knob to adjust the volume of the main
zone (your multichannel theater). The available range is 80 dB,
with 0.1 dB resolution over the top 60 dB, and 1 dB resolution for
the bottom 20 dB.
This control is speed-sensitive. When you turn the volume knob
quickly, it results in a larger volume change than when you turn
the knob the same amount, but more slowly. You can think of it as
being like variable-ratio, power-assisted steering in a luxury automobile. It delivers both rapid large-scale changes and fine
resolution, on an as-needed basis.
In addition, the volume knob can be used in conjunction with the
balance button to alter the relative volumes and/or delays of the
various speakers in the system.
The concept of a sound profile is central to making the most of
your investment in the Mark Levinson Nº40. In fact, much of the
section “Advanced Features” on page 7-1 deals with the subject;
please refer to that for more detail.
2-9
Suffice to say here that pressing the sound profile button cycles you
through the list of defined sound profiles, which are like little
“snapshots” of the system in different configurations. By choosing
a particular sound profile, the system can reconfigure itself on the
fly to better suit the needs of a particular piece of music or film.
Alternatively, you can think of a sound profile as being like a
“macro” of the many changes you might make to the system
manually to optimize it for a particular use. Rather than having to
do so manually every time, define it once, give it a name, and call it
up as needed.
When a profile is selected manually using either the front panel
sound profile button or the profile button on the remote control,
the Nº40 will remain in that profile until either a different profile or
a different input is selected. (Changes in the nature of the incoming
signal that might otherwise have triggered a change in profile are
ignored, in favor of the explicit user selection.)
Front Panel Operation Mark Levinson
2-10
Display Intensity Button
Recall Button
Pressing this button will cycle through several levels of illumination on the front panels of the Nº40, including both the alphanumeric display and the LCD display, as well as the various LED
indicators. The available brightness levels are High, Medium, Low,
and Off.
When Low is selected, the backlighting on the LCD display will be
turned off and most of the various LEDs will be off, turning on
again briefly when changes are made to let you know what is
happening. After a brief delay to let you see the change you have
made, they will once again extinguish themselves.
The balance button (described below) lets you make a large number
of incremental changes to the sound of the system, whether to
compensate for a poor recording or just to suit your fancy. These
changes include changes in both level (volume) and delay
(apparent distance of the sound).
Often, when you move on to another recording, the previous
settings can sound quite poor (since they are no longer
appropriate).
The recall button restores all such changes to their normal, calibrated levels and delays, as per the initial setup of your system. This
gets you back to the best starting point for any possible changes in
one easy step.
Balance Button
The balance control changes the perceived “balance” of the sound
along a left/right axis, and can be helpful when you are sitting offcenter. With a balance control, you can make the further speakers a
bit louder to compensate for their greater distance.
The balance button on the Nº40 does this and much more. By
clicking the balance button repeatedly, you cycle through all of the
various kinds of “balance” you might need in a multichannel
system:
• Subwoofer
Adjusts the level of the subwoofer channel, relative to the other
channels.
•Center
Adjusts the level of the center channel, relative to the other
channels.
• Stereo Front
Adjusts the level of the front left and front right channels, relative to the other channels.
Nº40 Media Console Front Panel Operation
• Surrounds
Adjusts the level of the surround channels, (normally at the
sides of the room) relative to the other channels.
• Surround Backs
Adjusts the level of the surround back channels, relative to the
other channels. (Note that this balance item can change
depending on your speaker setup.)
•L/R Balance
Adjusts the overall left/right balance of the system, much as the
balance control would in your car.
•F/B Fade
Adjusts the overall front/back balance of the system, much as
the fader control would in your car.
When you see the one you want displayed in the alpha-numeric
display on the Nº40 audio processor, use the volume knob to alter
the relative volume of the chosen subset of your speakers to meet
your requirements.
Mute Button and LED
Indicator
There is another incremental change you can make to the
“balance” of Nº40 audio processing. By pressing and holding the
balance button, you can alter the relative delays of the various
speakers in your system. This can be used to “tweak” the speaker
delays to create an extra sense of space, or (on the center channel)
to move the vocalist forward or back in the mix without altering
the basic volume of the vocals relative to the rest of the instruments. You could even use it to accommodate an off-center
listening position. (There is a better way of handling such things.
See “Sound Profile Menu” on page 5-19.)
After a few seconds, the balance mode will “timeout.” Alternatively,
enter can be pressed to return to normal operation more quickly,
should you wish to make other adjustments.
Pressing the mute button reduces the main output level of the Nº40
audio processor by an amount that you can modify, ranging from
-3 to -50 decibels, or completely off. When engaged, an LED indicator above the button lights up to indicate that the system is
muted. Pressing the mute button a second time without adjusting
the volume will return it to its previous setting. The magnitude of
the mute function is determined by the Mute level item in the User
options: Volume Options menu.
2-11
If you adjust the volume with either the front panel knob or the
remote control while the system is muted, the Nº40 will adjust its
volume from the muted level and disengage the mute function. The
factory default setting of the mute circuit is -20 dB. (See “Menu
Front Panel Operation Mark Levinson
System” on page 5-1 for information on changing the factory
default setting.)

Standby Button and
LED Indicator
When power is first applied to the Nº40 audio processor (the unit is
plugged in and the AC mains switch is pressed), it initializes
through a self-test and establishes communications with the Nº40
video processor. When this process is satisfactorily complete (it can
take about 30 seconds), the Nº40 goes to Standby and the LED indicators on both units begins to blink slowly.
Once the start-up process is complete, pressing standby on either
unit toggles both units between On and Standby.

Navigation Cluster
Enter Button
The up, down, left and right buttons are most often used to
move around within the menu system of the Nº40. For example, if you want to move to the right to see a submenu under a
currently selected menu item, press the right button on the
remote. If you want to move down a menu to highlight a different item, press the down button.
If you are at the end of a particular “branch” of the menu tree,
the up and down buttons can also be used to change the value
of a setting. For example, you would use the up and down
buttons to change the maximum volume setting, followed by
pressing enter to save the change.
Lastly, when you are in balance mode, the up, down, left and
right buttons will also control the front/back and left/right
balance, or the front/back and left/right delays (depending on
which “balance mode” you are in).
Recall that you can enter the delay adjustment mode by pressing and holding the balance button a few seconds; you can
think of this as a “power user” version of a balance adjustment.
The enter button has two functions in the menu system.
Menu Button
Input Select Rocker
Button
• If the current menu item has a submenu associated with it,
pressing enter will take you to that submenu. (In this situation, it works the same way as the right button.)
• If the highlighted menu item is a value (for example, the
maximum volume value in dB, or the speaker output levels
in dB, or the speaker distance in either feet or meters),
pressing enter will save any changes to the value.
During normal operation of the Nº40, the menu button
displays a menu of system services, including the setup menu.
Please see “Menu System” on page 5-1 for more information.
When in a menu, pressing the menu button also serves as a
“cancel” button does on a computer, allowing you to exit a
particular menu item without saving any changes.
The input select rocker button cycles through the list of defined
inputs, in either direction (based on which end of the rocker
you press). It duplicates the function of the input select knob
on the front panel.
Nº40 Media Console Remote Control
Surround Mode
Rocker Button
Volume Rocker Button
The surround mode rocker button cycles through the list of
available surround modes, in either direction (based on which
end of the rocker you press). It duplicates the function of the
surround mode knob on the front panel. As with that knob, the
list of available surround modes changes depending on what
type of audio signal has been selected. In general, there are
many more surround mode options for two-channel signals
than for multichannel signals.
This rocker button adjusts the volume of the main zone. The
available range is 100 dB, with is 0.1 dB resolution over the top
80 dB, and 1 dB resolution for the bottom 20 dB.
The Nº40 initially changes its volume slowly in response to
receiving this command from the remote control; it then accelerates. It does so because there are so many intermediate
volumes to cover (potentially 820 of them between off and
maximum volume). Beginning slowly makes it easy to accurately make minor adjustments to the volume. Subsequent
acceleration allows you to quickly make larger adjustments to
the volume of the system.
If you select a remote zone using the zone knob, you can also
adjust the volume in that remote zone from the remote control
in the main room. Be careful about doing so, however, as you
are not in the remote zone to judge the magnitude of the
change you are making. It is usually better to adjust the volume
in the remote zone from the remote zone itself, using the IR
input provided for such purposes.
4-3
Sound Profile Button
In addition, the volume rocker button can be used in conjunction with the balance button to alter the relative volumes and/
or delays of the various speakers in the system. (see below)
The concept of a sound profile is central to making the most of
your investment in the Mark Levinson Nº40. In fact, much of
the section Advanced User Features deals with the subject;
please refer to that for more detail.
Suffice to say here that pressing the profile button cycles you
through the list of defined sound profiles, which are like little
“snapshots” of the system in different configurations. By choosing a particular sound profile, the system can reconfigure itself
on the fly to better suit the needs of a particular piece of music
or film.
Alternatively, you can think of a sound profile as being like a
“macro” of the many changes you might make to the system
manually to optimize it for a particular use. Rather than having
to do so manually every time, simply define it once, give it a
name, and call it up as needed.
Remote Control Mark Levinson
When a profile is selected manually using either the front panel
sound profile button or the profile button on the remote
control, the Nº40 will remain in that profile until either a different profile or a different input is selected. (Specifically, changes
in the nature of the incoming signal that might otherwise have
triggered a change in profile will be ignored, in favor of the
explicit selection on the part of the user.)

Balance Button
The balance control changes the perceived “balance” of the sound
along a left/right axis, and can be helpful when you are sitting offcenter. With a balance control, you can make the further speakers a
bit louder to compensate for their greater distance.
The balance button on the Nº40 does this and much more. By
clicking the balance button repeatedly, you cycle through all of the
various kinds of “balance” you might need in a multichannel

• Subwoofer
Adjusts the level of the subwoofer channel, relative to the other

Adjusts the level of the front left and front right channels, relative to the other channels.
• Surrounds
Adjusts the level of the surround channels, (normally at the

• Surround Backs
Adjusts the level of the surround back channels, relative to the
other channels. (Note that this balance item can change
depending on your speaker setup.)

When you see the one you want displayed in the alpha-numeric
display on the Nº40 audio processor, use the volume knob to alter

listening position. (There is a better way of handling such things.
See “Sound Profile Menu” on page 5-19.)
After a few seconds, the balance mode will “time-out.” Alternatively, you can press the enter button to return to normal operation
more quickly.
Mute button
F1, F2, F3 function
keys
Pressing the mute button will reduce the main output level of the
Nº40 audio processor by a user-modifiable amount, ranging from 1
to 100 decibels. When engaged, an LED indicator above the mute
button on the front panel lights up to indicate that the system is
muted. Pressing the mute button a second time without adjusting
the volume will return it to its previous setting.
The magnitude of the mute function is determined by the Mute
level item in the User options: Volume Options menu.
If you adjust the volume with either the front panel volume knob
or the volume rocker button on the remote control while the
system is muted, the Nº40 will adjust its volume from the muted
volume and disengage the mute function. The factory default
setting of the mute circuit is -20 dB. (See The Nº40 Menu System for
information on changing the factory default setting.)
There is a wide range of functionality provided by the Nº40. If there
were a button for every one of those functions, its remote control
would be too large. Instead, we provide two mechanisms for quick
and easy access to those features you especially like to use.
The menu button calls up a toolbar that includes the setup menu
and several other items of interest. You can edit this toolbar as you
see fit, with the exception of the first item: the setup menu must
always be accessible, and cannot be removed. If you have two or
three functions that you want to access even faster, you can use the
function keys. You (or your installer) can specify which features
each of these three buttons will “trigger.” This is done in the User
options: Control Options menu of the setup menu. You might associate any of these function keys with a particular sound profile
(saving you from scrolling through a list), or a listener position, or a
THX toggle, or even a particular input. The list of options is quite
extensive, and the choice is entirely yours, based on whatever
makes the most sense to you.

After a few seconds, the backlighting will turn off to conserve
battery power.
When power is first applied to the Nº40 video processor (for
example, the unit is plugged in and the AC mains switch is
depressed), it goes through an initialization process that involves
self-testing and establishing communications with the Nº40 audio
processor. When this process has been satisfactorily completed (it
takes about 30 seconds), the Nº40 will enter standby and the LED
indicators on both units will begin to blink slowly.
Once the start-up process is complete, pressing standby on either
unit or the remote control will toggle both units between On and
Standby.
Using a #3 (small) Phillips screwdriver, remove the bottom plate to
access the battery compartment when it becomes necessary to
replace batteries. The Nº40 remote control uses two alkaline AAA

The Mark Levinson Nº40 Media Console uses a card cage design for
several reasons.
One important advantage of the card cage design is that it allows
you to take advantage of hardware features if you so choose. For
example, the Nº40 can support up to five zones: the main zone plus
as many as four additional and independent Remote or Record
zones, which we refer to as “RZones.” (As you will see, the hardware
involved in either a Remote zone or a Record zone is the same.)

Our card cage also provides a mechanism by which new technology
can more easily be introduced into the product, even after it has
been purchased and installed.
This flexibility of the design can be a two-edged sword, however.

specific to the particular zone.
Connect either (or both) of the video outputs to your intended
remote zone display device or video recorder, according to your
system design.These video outputs can easily drive extremely long
lengths of high quality 75Ω cable; however, as with any video
signal, long cable runs really require excellent quality cable to avoid
signal deterioration. Please consult with your dealer on the best
choice of video cable to suit your system design.
From the front panel, you can select the zone you wish to change
using the zone knob, and then route any defined input to both the
video outputs (S-video and composite) associated with the selected
RZone.
If you need to control a particular zone from a remote location,
simply use IR “repeaters” to direct appropriate infrared commands
to the IR input on that RZone card, in the video processor. Any
commands received at that IR input will be interpreted as being
intended for that particular RZone.

control ports to one of the power amplifier’s control ports using a
“straight-through” RJ-45 cable. If there are additional Mark
Levinson PHAST-compatible components in the system, daisy
Rear Panel Operation Mark Levinson
chain them in a similar way. These are fully bidirectional ports, and
the order in which they are connected is not important.
The RJ-45 cable needed for the connection between the Nº40 and
other PHAST-compatible Mark Levinson components can be
purchased from your Mark Levinson dealer. It can also be easily and
inexpensively made to length using two RJ-45 connectors and the
appropriate length (up to 100 feet/30 meters) of RJ-45 (flat, eight
conductor) cable.
RJ-45 cables and connectors are used throughout the world for both
telecommunications and computers, and are widely available at
low cost. The connectors are crimped on to the ends of the cable
such that pin 1 at one end is connected to pin 1 at the other end.
Such a “straight-through” connection is (counter-intuitively) made
by introducing a 180° twist in the cable between the two ends, as
shown below.

this manual can damage the Nº40 and the associated components, and will void the product warranties.
These ports also provide for extensive home automation flexibility
via the PHAST™ protocols, should you be interested in integrating
other brands of products into the system in a more comprehensive
control system. Your dealer can assist you in taking advantage of
these advanced features.
The Nº40 also includes two RS-232 ports. Port 1 is reserved for
future applications. Port 2 can be used in conjunction with external
control systems such as Audioaccess, AMX, or Crestron (port 2).
Your dealer can assist you in taking advantage of these advanced
features.
RS-232 port 2 can also be used to update the operating software of
the Nº40, so that your system will be able to incorporate new
features as they are introduced. Once again, your dealer can assist
you in taking advantage of these advanced features, should the
need arise.
The pin connections used on the RJ-11 connectors used for the RS232 ports are as follows:

The two “halves” of the Nº40 (the video processor and the audio
processor) need to be able to “talk to each other” in order to coordinate their efforts. The Nº40 communications port on each
component is reserved for this purpose.
Please connect this connector and similarly-labelled connector on
the other component, using the supplied RJ-11 communications
cable. After having done so, power up both units and please wait
until their standby LEDs begin blinking together, indicating that
the initialization and self-test routines are complete and the system
has entered standby.
Each of the three remote on/off triggers can be configured by your
installer to provide either 5V or 12V DC trigger signals.
These programmable triggers can be used to control other manufacturers’ power amplifiers, or to lower a projection television screen,
close drapes, or almost anything else you (or your installer) might
imagine. The most common way of controlling them is as part of a
sound profile, although your installer can also control them via RS232 commands, or via IR commands. Please see The Nº40 Menu
System for more detail on using sound profiles.
The tip polarity and power rating for each of these triggers is as
shown below:

A 1⁄8" mini-jack labeled IR input near the lower right corner of the
rear panel provides direct access to the infrared control circuitry of
the Nº40’s main zone.
The incoming signal for the remote IR input should conform to
widely-accepted IR repeater standards: that is, the signal present
should be between 5-12 volts DC, with a positive tip polarity, as
shown below:

Audio RZone
Expansion
As shipped from the factory, slots 8 and 9 are normally empty
except for a blank piece of metal that covers the opening. These
slots can be used for the audio portions of additional Remote or
Record zones (“RZones”) immediately, should you require them.
The RZones are counted from right to left; hence slot 8 is reserved
for RZone 4, and slot 9 is reserved for RZone 3. This is shifted one
slot over from the arrangement on the video processor, since the
audio processing and system communications card occupies slot 12
(see below).
As an alternative to their application for RZone use, slots 8 and 9
can instead be used for additional input cards, should they be
needed.
Audio RZones 1 & 2
As shipped from the factory, slots 10 and 11 are normally used
for the audio portions of the two standard Remote or Record
zones (“RZones”).
Figure 3-20: Audio RZones. The RZones are counted from right to left; hence slot 10 is
reserved for RZone 2, and slot 11 is reserved for RZone 1. This is
shifted one slot over from the arrangement on the video processor, since the audio processing and system communications
card occupies slot 12 (see below).
Each card includes two single-ended analog output pairs on
custom-designed RCA connectors, as well as an S/PDIF digital
output on another RCA connector. Each card also includes two
SHARC DSP chips so it can do real-time decoding and downmix

regardless of format, from a remote location. You can also make
a two-channel recording of multichannel material.
Nº40 Media Console Rear Panel Operation
Connect either (or both) of the audio outputs to your intended
remote zone system or audio recorder, according to your system
design.These audio outputs can easily drive extremely long
lengths of high quality cable; however, as with any audio
signal, long cable runs really require excellent quality cable to
avoid signal deterioration. Please consult with your dealer on
the best choice of cable to suit your system design.
From the front panel, you can select the zone you wish to
change using the zone knob, and then route any defined input
to both the audio outputs associated with the selected RZone
using the input select knob.
If you need to control a particular zone from a remote location,
simply use IR “repeaters” to direct appropriate infrared
commands to the IR input on that RZone card, in the video
processor. Any commands received at an IR input will be interpreted as being intended for that particular RZone.
Keep track of how these outputs are used, either by keeping a
simple list or by making a note on the Hookup Chart at the end
of this manual.

Optional Equipment
We believe that the Mark Levinson Nº40 with its standard equipment complement will meet the needs of almost every owner.
However, there is ample room for further expansion of the platform, should you want to customize your Nº40 further.
We have listed the optional equipment that is available, for your
reference.
3-20
Extra Input Modules
The first and most obvious addition for the Nº40 is one or more
extra input modules, above and beyond those that are included as
standard equipment. Any of the modules you see in the Nº40 can
also be purchased separately, and can be installed in one of the
available unused slots, with some limitations.
For the video processor:
•Slots 1-4
Each slot supports up to three analog input signals (either
composite, S-video or component).
•Slots 5-8
Each slot supports a single video input that can be either analog
or digital (when digital video input capability is offered); these
slots can also support separate sync signals. (For now, these are
where you would use component input cards.)
• Slots 9-12
These slots are reserved for the video portions of an RZone
(Remote or Record zone) use, and support analog output and
zone-specific IR input. Although not yet available due to the
lack of an industry standard, these slots will also support digital
video input and output. Note that such cards will not be available until there is an accepted industry standard for secure
distribution of digital video in the home.
For the audio processor:
•Slots 1-7
Each slot can support up to five separate audio signals, either
analog pairs or digital (two-channel or multichannel, as
needed).
• Slots 8-11
These slots are reserved for the audio portion of an RZone. They
can route either two-channel analog or digital signals to a
Remote or Record zone, and as discussed, the audio RZone card
Nº40 Media Console Rear Panel Operation
has significant on-board DSP resources for doing decoding and
downmixing as needed.
•Slot 12
This slot is reserved for the main zone digital signal processing
and the communications with the Nº40 video processor.
Although this card can be upgraded (if necessary at some point
in the future), the function of the card contained by this slot
will remain the same.
If you need any additional input cards for your Nº40, please contact
an authorized Mark Levinson dealer.
Extra RZone Cards
Amp Communication

Digital Output Card
The Nº40 supports up to four RZones (Remote and Record zones),
in order to support complex systems that might require as many as
five different sources being sent in as many as five different directions, simultaneously. Two RZones (both audio and video) are
provided as standard equipment. Additional RZone cards can be
added in pairs (audio and video) as needed to the maximum of four
RZones. (The fifth zone is your main room or theater.)
If your system would benefit from additional RZones beyond the
two that come as standard equipment in the Nº40, please contact
your authorized Mark Levinson dealer.

Menu System
Overview
The Mark Levinson Nº40 Media Console includes a comprehensive
and sophisticated graphical menu system that serves several critical
functions:
• it provides for initial configuration of the system with regard to
speakers, crossover, multiple zones, and defining inputs based
on your source components
• it allows you to define a variety of “user options” to ensure that
the system behaves the way you prefer with regard to items like
maximum volume settings, how, when and where information
is displayed, etc.
• it provides for fairly extensive customizing of the user experience, in effect allowing you to make the Nº40 work the way you
think it should (rather than being limited to the way we
thought it should work)
5-1
• it also allows you to define certain automatic responses, either
to selecting a particular input or to detecting a particular type of
audio signal; this capability effectively enables the system to
reconfigure itself based on what you are doing, without further
intervention from you
While little of this is difficult to understand, it nonetheless represents a lot of ground to cover. We will break it up into smaller
sections, according to the main menu icons in the menu system.
Throughout the menu system, certain paradigms hold true. First,
and perhaps most importantly, it is designed to let you see not only
where you are at any point in time, but how you got there. This
hierarchical “menu tree” approach to displaying the menu system
makes it easier to understand the entire system, since you can see
all (or at least most) of the portion you are in, at all times.
Second, it is designed to give you as much information as possible
without going unnecessarily deep into the menu system. Wherever
practical, the current setting for a parameter is displayed with the
parameter’s name, and associated parameters are grouped together
so as to all be visible at once. (The benefits of this organization
become more obvious once you begin to use the menu system.)
The menu system was also designed to lead you through the setup
and customizing process in a logical manner. While nothing
prevents you from hopping back and forth between major menu
groups, you will find that the fastest and simplest way of setting up
Menu System Mark Levinson
the system will be to start at the top, and simply work your way
through. This is important, since selections you make early on
affect the options you are subsequently given. For example, how
you elect to use your auxiliary channels (aux 1 and aux 2) will alter
many menu items further on in the menu system that pertain to
adjusting and using those channels.

Navigating The Menus
To access the menu system, press menu on either the front panel of
the video processor or on the remote control. This will bring up the
toolbars display (on the LCD display and on the monitor output,
and on your main video outputs as well, unless and until you turn
off the menus on the main video output), which is a list of up to six
different tools available at the push of the menu button. By default,
the first of these (which is always the setup menu) will be highlighted. Press enter to select it.
The Nº40 will generate the top level of the setup menu. Along the
left side of the screen you will see six icons, which correspond to:
• The Speakers Menu
• The Sound Profile Menu
• The Define Input Menu
• The Audio Defaults Menu
•The User Options Menu
• The Output Zones Menu
In the larger space to the right of this column of icons, you will see
the About… screen of information for your system. This information is displayed whenever you first enter the setup menu.
What you see in front of you is the “top level” of the Nº40’s hierarchical menu system. It is designed to help you find the controls and
features you want, quickly and easily.
One way to think of this system is to liken it to the branches and
leaves of a tree: from the main tree trunk, you can follow any of
several big branches outward, turning onto smaller and smaller
branches, until you reach the end of a branch, which is a “leaf.”
Ultimately, it is at these “leaves” of the tree that all settings are
changed. The branches that lead to them serve only to help
organize the hundreds of leaves, so you can find the one you want,
when you want it.
In the setup menu, the “big branches” are represented by icons
denoting the major areas in the Nº40 that can be modified in some
way. These “big branches” split into smaller ones, and then smaller
ones again, until they end in a “leaf.” You always modify the value
of a particular setting at a “leaf.”
Nº40 Media Console Menu System
Try to remember this “branch” and “leaf” idea. We will come back
to it in a few moments.
Using the up/down buttons on the remote control (or the zone
knob on the video processor), you can move the highlighted item
among any of menu items at the current level of the menu.
Press the right arrow button on the remote to move into the item’s
submenu.
If you move to the right by mistake, press either the left arrow
button on the remote or the menu button (which serves as a
“cancel” button within the menu system) to exit back to the
previous level of the setup menu.
Continue navigating around the menu until you find the item you
wish to change, at a “leaf” on the menu tree. Press the right arrow
button to edit the value of this last item; the menu will generally
display a list of the available values for that item. You can use either
the up/down buttons on the remote or the zone knob on the video
processor to select among the available values. Press enter or left
arrow to save the change and return up to the next higher
“branch.”
If you begin to make a change and decide against it, you can cancel
the change and move up one level in the menu by pressing menu.
So, to summarize:
• Pressing menu when outside the menu system calls up the
system’s toolbars on the video display, the first of which is the
setup menu. Press enter to enter the setup menu.
• Use the up/down arrow buttons (or the zone knob on the front
panel) to move among menu items on a given level.
• Use the right arrow button to move right, to an item’s
submenu.
• When you reach a “leaf” of the menu tree at which you want to
modify a setting, do so with the up/down arrow buttons (or the
zone knob on the front panel), and save the change by pressing
either enter or left arrow. (The exception to this is when you are
editing a name, in which case the left arrow moves the cursor to
the left within the word, for convenience when correcting an
error. You must press enter in a naming menu item to save your
change.)
• Use either menu (as a cancel button) to move left, “up” a level
in the menu system, without saving any changes.
5-3
• Exit the menu system entirely by moving left (or pressing
menu) off the column of icons that represent the first level of
the menu system.
Menu System Mark Levinson
Front panel menu navigation
Sometimes it is more convenient to navigate the menu system of
the Nº40 from the front panel, rather than from the remote control.
The controls on the front panel you need to use are as follows:
•Menu
The menu button on the front panel of the Nº40 video processor performs exactly as the menu button on the remote control
would.
•Enter
The enter function performs exactly as the enter button on the
remote control would.
•Zone knob
The Nº40 video processor’s front panel zone knob (the knob
adjacent to the menu and enter buttons) operates in the same
fashion as the up/down buttons on the remote control, allowing you to either move up and down in a menu list, or to increment/decrement a value of a menu item.

Nº40 Media Console Menu System
The About... Screen
The first screen you see in the setup menu consists of a column of
icons (each of which represents a major area within the setup
menu) and a large field to the right of those icons that contains
certain information about your Mark Levinson Nº40.
We call this field of information the Nº40’s “About…” screen, since
it is similar to the “About…” boxes that you see on your computer,
describing whatever application you might be in at the time.
When you move to the right off any of the icons, the submenus of
the menu icon you have selected replace the “About…” screen.
The Nº40 Media Console has five major components in its software.
The Operating System (OS) software includes most of what you see
in the menus, as well as all of the software that responds to your
actions on either front panel or the remote control. In this regard, it
is much like the operating system of a computer. There is an OS
component for each component (Audio and Video).
System Locked/
Unlocked
Personalization
The Digital Signal Processing (DSP) software includes a variety of
applications that are specific to particular tasks that need to be
performed, such as decoding Dolby Digital or DTS, or performing
THX Ultra2 post-processing. There are two blocks of DSP code used
in the Main Zone (A and B), and another block of DSP code used by
the RZone DSPs. Each of these software components is identified
with a version number. The Nº40 is modular in its software design
as well as in its hardware design, allowing it to add new capabilities
as time and technology move on. Your Mark Levinson dealer can
update your software to incorporate such new features or capabilities as they become available.
The About… screen also indicates whether the setup of your Nº40
has been locked. Your dealer can lock the Nº40 system settings to
prevent accidental corruption of important system settings.
Your dealer can also create a brief personalization message on this
screen, which can be up to 256 characters long, and can occupy up
to six lines of text. This text area can be used by your dealer,
perhaps to identify the system as yours as a deterrence to would-be
thieves. For this reason, this field can not be edited from within the
Nº40 itself.
5-5
Menu System Mark Levinson
Speakers Menu
The first thing you need to tell your Nº40 Media Console about is
the speakers with which it has to work. The Nº40 has remarkably
powerful and flexible bass management capabilities that allow it to
redirect deep bass away from any speaker than cannot easily reproduce it, to those that can.
In addition, it can (within limits) compensate for any speakers that
might be missing from what would be considered a “standard” 5.1
channel configuration, and it can take advantage of additional
speakers beyond a “standard” 5.1 channel configuration.
Many of the menus within the Nº40 setup menu system automatically change to reflect the nature of the speakers you are using. This
is another important reason for defining the speakers used in the
system first, since without this critical information you may find
that a needed feature elsewhere in the menus is not available.
But in order to do these things, you (or your installer) must provide
certain information about the speakers you have selected to use.
5-6
Note The information conveyed to the Nº40 through the Speakers menu
describes the actual speakers available in the system and their optimal
use. Please complete this section of the menu system before moving
on to any other.
If you would like to use your speakers differently some of the time,
for example using your front speakers full range for two-channel
stereo listening, use the “sound profile” capabilities of the Nº40,
described later.
Center
Subwoofer
If you are using a center channel speaker, choose “yes” in the menu
and center channel information will be directed to the center
channel output.
If for some reason you cannot use a center channel speaker in your
system, choose “no” in the menu. The Nº40 will create a “phantom
center channel” by splitting center channel information equally
between the front left and front right speakers.
If you using one or more subwoofers in the system, select “yes” in
the menu. If not, choose “no” (in which case the information that
would normally be reproduced by a subwoofer will be redirected to
other speakers in the system that can handle deep bass).
Left/Right Surround
If you using one or more surround speakers in the system, select
“yes” in the menu. If not, choose “no.”
Nº40 Media Console Menu System
Note that in many systems, these speakers can be described as
“side” speakers. We have elected to use the standard nomenclature
as advocated by Lucasfilm for their Home THX® Audio System and
Surround•EX technologies. The Nº40 supports many possible
system configurations, and using industry-standard terminology
should minimize any possible confusion.
For example, if you have a standard 5.1 channel system (front left,
front center and front right, plus surround left and surround right,
plus a subwoofer), you would choose “yes” in this menu and use
the Nº40 surround outputs to drive the amplifiers associated with
your surround speakers.
In a system configured to take advantage of two pairs of surround
speakers (as in one Surround•EX configuration), your primary
surround speakers are located to the sides of the listening area, and
the surround back speakers will be behind you.
Auxiliary
In addition to the standard 5.1 channels found in all modern multichannel systems, the Nº40 provides two channels that can be
configured for any of several uses, depending on your associated
equipment.
None
If you have a standard 5.1 channel system (front left, front center
and front right, plus surround left and surround right, plus a
subwoofer), choose “none” in this menu. The speaker setup in the
room would look something like the following:

The indicated angles are measured from front-and-center, and are

angles indicated, and try to maintain as much symmetry as possible.)
Note The subwoofer is not shown in these drawings, since no one
subwoofer location is always going to be optimal in all rooms.
Menu System Mark Levinson
If there is information that would normally be presented to the aux
outputs (for example, in a Surround•EX sound track), this setting
will cause it to be redirected to the available pair of surround
speakers to ensure that you do not miss anything in the
soundtrack.
Extra mono subwoofer only
Select the “extra mono sub only” option for the auxiliary channels
if you have a standard 5.1 channel system, but prefer to use two
separate subwoofers.
The extra subwoofer is a second, mono channel that is identical to
the main subwoofer output in content, but which has its own
distance and level setting adjustments. This is often the best way to
achieve maximally uniform and accurate bass response in a room.
Playing the same information in carefully chosen, staggered locations in the room minimizes the adverse effects of room modes on
bass reproduction. Please consult with your dealer on the best way
to take advantage of this capability in your particular room.
5-8
Specifically, in this setting:
• The subwoofer channel becomes the sub #1 channel
• The aux 1 channel remains unused
• The aux 2 channel becomes the sub #2 channel.
In this case, the sub #1 and the sub #2 outputs contain the same
information, but operate with independent distance and level
settings, indicated by “sub #1” and “sub #2” in the menu system
when this option is selected.
Stereo left subwoofer only
Some installations require separate left and right subwoofers, rather
than two mono subwoofers. This is partly a matter of preference,
and sometimes a matter of speaker design philosophy. If your
system requires this approach but does not require a surround back
(Sb), select “stereo left sub only” from the menu.
In this case, the aux 2 output becomes the left subwoofer output,
and contains all redirected bass from any speakers on the left side of
the room that are bass-limited; in addition, it contains one-half of
the center channel’s redirected bass (if any), and one-half of the low
frequency effects (LFE) channel (if any) in discrete multichannel
soundtracks.
Nº40 Media Console Menu System
To summarize, in this setting:
• The subwoofer channel becomes the right sub channel
• The aux 1 channel remains unused
• The aux 2 channel becomes the left sub channel.
One surround back speaker
If your system requires only a surround back (Sb) in addition to the
standard 5.1 channels (front left, front center and front right, plus
surround left and surround right, plus a subwoofer), select “one
surround back” from the menu.
In this case, the aux 1 output becomes the surround back (Sb)
output to be used with the amplifier that drives the surround back
speaker, as shown:

To summarize, in this setting:
• The aux 1 channel becomes the surround back channel
• The aux 2 channel remains unused.
5-9
Two surround back speakers
If you have two separate pairs of surround speakers in the main
zone of the system, select “two surround backs” from the menu.
To summarize, in this setting:
Menu System Mark Levinson
• The aux 1 channel becomes the surround back right
channel (sbr)
• The aux 2 channel becomes the surround back left
channel (sbl).
THX recommends that these speakers be placed together, facing
forward at the rear of the room for best Advanced Speaker Array
effects as indicated below:

Nº40 Media Console Menu System
We have omitted indicating where the subwoofer is located in these
drawings, since no one subwoofer location is always going to be
optimal in all rooms.
The surround back speakers can be used to reproduce Surround•EX
surround information, and other similar information on nonencoded material (such as DTS 6.1 ES). They are generally designated Sbl and Sbr for surround back left and surround back right,
respectively. These speakers are used to provide center fill information behind you to maximize surround envelopment and certain
types of “flyover” effects.
Surround back speaker and mono subwoofer
Alternatively, you can decide to use the extra two channels of
hardware in your Nº40 for an extra subwoofer and a single
surround back (Sb) channel.
The extra subwoofer is a second, mono channel that is identical to
the main subwoofer output in content, but which has its own
distance and level setting adjustments. This approach is often the
best way to achieve maximally uniform and accurate bass response
in a room. Playing the same information in carefully chosen, staggered locations in the room minimizes the adverse effects of room
modes on bass reproduction. Please consult with your dealer on the
best way to take advantage of this capability in your particular
room.
5-11
The surround back (Sb) channel is used to drive the amplifier
channel that in turn drives a single surround back speaker that is
normally located directly behind the primary listening position.
This speaker is used to provide center fill information behind you
to maximize surround envelopment and certain types of “flyover”
effects. The resulting room layout looks the same as in Figure 5-2 on
page 5-9.
The indicated angles are measured from front-and-center, and are
approximate guidelines only. (Try to stay within about 10° of the
angles indicated, and try to maintain as much symmetry as possible.)
We have omitted indicating where the subwoofers are located in
these drawings, since no subwoofer location is always going to be
optimal, in all rooms.
Specifically,
• The subwoofer channel becomes the sub #1 channel
• The aux 1 channel becomes the surround back channel
• The aux 2 channel becomes the sub #2 channel.
In this case, the sub #1 and the sub #2 outputs contain the same
information, but operate with independent distance and level
Menu System Mark Levinson
settings, indicated by “sub #1” and “sub #2” in the menu system
when this option is selected.
Surround back and left subwoofer
Some installations require separate left and right subwoofers, rather
than two mono subwoofers. This is partly a matter of preference,
and sometimes a matter of speaker design philosophy. If your
system requires this approach as well as a surround back (Sb), select
“surround back & left sub” from the menu.
In this case, the aux 1 output becomes the surround back output to
be used with the amplifier that drives the surround back speaker.
The resulting room layout looks the same as in Figure 5-2 on page
5-9.
In this case, the aux 2 output becomes the left subwoofer output,
and contains all redirected bass from any speakers on the left side of
the room that are bass-limited; in addition, it contains one-half of
the redirected center channel bass (if any), and one-half of the low
frequency effects (LFE) channel (if any) in discrete multichannel
soundtracks.
5-12
Crossovers
To summarize, in this setting:
• The subwoofer channel becomes the right sub channel
• The aux 1 channel becomes the surround back channel
• The aux 2 channel becomes the left sub channel.
Once you have defined what speakers are going to be used in the
main zone, you can further specify the nature of the crossovers
used with those speakers. Note that your options in this section of
the menu will vary somewhat, depending on how you elect to use
the aux channels. The menus update dynamically, to reflect how
you elect to use the available hardware.
If you are using THX-certified speakers…
If you are using THX-certified loudspeakers, you should use the
THX crossover frequency of 80 Hz and a low pass crossover slope of
24 dB/octave. These options are listed as 80 Hz, THX and 24dB/oct,
THX in the menu system as a reminder. Please make sure that if
your THX subwoofer has switches or controls to give you different
options, make sure that those switches/controls are in the “THX”
position. This will ensure the correct alignment to the main
speakers.
Frequency
For each logical group of loudspeakers other than subwoofers, you
are given a choice as to both the crossover frequency and the cross-
Nº40 Media Console Menu System
over slope that ought to be used. Thus, you have independent
control over the crossover characteristics for each of the following
groups:
• Front left and front right
•Center
• Surround left and surround right
• Any surround back channel(s) you have elected to use.
For each of these logical groups of speakers, you can select a crossover frequency from among the following:
• Full range (e.g., not “crossed over” at all)
• 30 Hz to 100 Hz, in 10 Hz increments.
Similarly, for each of these logical groups of speakers, you can select
a crossover slope of either:
• 12 dB per octave, THX
•18 dB per octave.
If you are using THX-certified loudspeakers, you should use the
THX crossover frequency of 80 Hz, and a high pass crossover slope
of 12 dB/octave. These options are listed as “80 Hz, THX” and “12
dB/oct, THX” in the menu system, as a reminder.
Caution In extreme cases, you can damage center and surround speakers
speakers by sending them lower-frequency information than they
are designed to handle.
These crossover settings are not required in order to take advantage
of the Home THX processing mode. Rather, they are designed to
integrate THX-certified loudspeakers into the system as seamlessly
as possible.
Slope
By default, the subwoofer receives any low frequency information
that cannot be handled by the other speakers in the system, as
defined by the crossover settings for those speakers. This approach
is sometimes called a “complementary” crossover, in that the
output of the subwoofer is designed to complement that of all the
other channels perfectly, to ensure that all information is
reproduced.
5-13
However, some subwoofers have their own built-in crossovers that
cannot be bypassed. Since it is usually inadvisable to have multiple
crossovers in series with each other, the Nº40 also provides a “full
range” option for the subwoofer output. This full range output is
Menu System Mark Levinson
the sum of all active channels for whatever is being played in the
main zone, and is a full bandwidth mono signal. An appropriate
low pass filter must be applied to this signal before it is reproduced,
presumably in the subwoofer’s own electronics.
(Note that to ensure that all information is reproduced in this
scenario, any speakers that have a high pass filter associated with
them should use the same frequency, and that frequency must be
the same as is used by the external subwoofer crossover.)
Finally, there are two more options: we can specify that the low
pass filter on the subwoofer output be either an 18 dB per octave or
a 24 dB per octave low pass filter. The latter of these two crossover
slopes is the one advocated by THX for use with THX-certified loudspeakers, and is denoted by “24 dB per octave, THX” in the menu as
a reminder.
Thus the subwoofer options are limited to defining the nature of
the crossover slope that will be employed (since the frequency
information is defined by what is “left over” from the high pass
portions of the crossover). In summary, they are:
5-14
THX Audio Setup
• Complementary
•Full range
• 18 dB per octave
• 24 dB per octave, THX.
If you are using THX-certified speakers, you should use the THX
crossover frequency of 80 Hz and a low pass crossover slope of 24
dB per octave for the subwoofer. These options are listed as “80 Hz,
THX” and “24 dB per octave, THX” in the menu system, as a
reminder. These crossover settings are not required in order to take
advantage of the Home THX processing mode. Rather, they are
designed to integrate THX-certified loudspeakers into the system as
seamlessly as possible.
This menu allows you to set up THX Ultra2 processing for your
speaker and room setup.
Boundary gain compensation
If your listening position results in most of the listeners being close
to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that the overall sound quality becomes
boomy. The Boundary Gain Compensation (BGC) feature provides
an improved bass balance. This menu is used to tell the Nº40
whether to allow or prohibit use of the BGC feature in your
listening position. You should only allow this feature to be used if
your subwoofer is THX Ultra2
certified or extends down to at least 20Hz.
Nº40 Media Console Menu System
ASA back separation
If you have two back speakers, the Nº40 needs to get an indication
of how far apart they are in order to implement the Advanced
Speaker Array technology of THX Ultra2 Cinema and THX Music
Mode. You will be given the following options:
• Together: Separation is less than 1 foot (<0.3m)
• Intermediate: Separation is between 1 and 4 feet (>0.3–1.2m)
• Apart: Separation is greater than 4 feet (>1.2m).
THX recommends that they be placed together facing forward for
best ASA effect.
Listener position
One of the big advantages of high quality multichannel systems is
that the “sweet spot” in which a film can be enjoyed is expanded as
compared to simple two-channel stereo. However, there are limits.
In particular, if you want the best possible performance in two or
three different locations in the room, the distances from the
speakers and their perceived output levels can vary significantly.
You may have a “best seat in the house” location in the middle of
the room, where the speakers are placed symmetrically about you.
You may, however, also want to optimize the sound for when are
reading in your favorite chair, or while you work at your desk – all
positions that are unlikely to be “optimal” on their own.
By creating different listener positions that correspond to the main
locations from which you might use the system, you can optimize
the performance of the system for different situations, including
those in which you do not want to be limited to the primary
seating area.
The listener position section of the speaker menu allows you to give
a meaningful name to each position, and then to calibrate the
distances and output levels required to compensate for different
listening locations in the room.
Up to four listener positions can be defined. You can associate any
defined listener position with any sound profile you care to define.
See The Sound Profile Menu for more information on their use.

Name
The name can be up to twelve characters long (e.g., “main chair,”
“couch,” “desk”). This name is entered with the keyboard window.
To do so:
1. Select the “name” menu item
2. Press enter (or right arrow, on the remote). This brings up the
keyboard window. The current name is displayed in the Name
Menu System Mark Levinson
Line with a blinking cursor on the currently active character. A
keyboard with characters and operations to select is shown with
one highlighted character
3. Rotate the zone knob and the input select knob (or use the up/
down arrows on the remote) to move the highlight to the
desired character or operation and press enter to select it
The selected character will be added to the Name Line at the
cursor, and the cursor will move one space to the right.
The following operations are available to complete editing the
name:
• insert Adds a space at the cursor position
• del Deletes the current cursor position
• clear Clears the entire Name Line
• cap Toggles the characters between capital and small letters
5-16
• save Saves the current Name Line and returns to the menu
• quit Returns to the menu without saving the Name Line
• ––> Moves the cursor one space to the right
• <–– Moves the cursor one space to the left.
4. Repeat steps 1 - 3 to fill in the name.
5. To end the editing session, use the save or quit operations. The
menu button also performs the quit operation directly.
Distances
The first item under “distances” gives you a choice of either English
(feet) or metric (meters) measurement systems. Pick whichever you
prefer. Then measure the straight-line distance between the front of
each speaker in turn and the listener position you are defining. (A
tape measure is helpful for doing this.) By entering these distances
into the Nº40, it can calculate the appropriate delays required to
ensure that the sounds from each channel arrive at your listening
position at the correct time.
Levels
The next and last step in defining a listening position is to calibrate
the output levels for the various speakers to be correct for that location. Use a sound pressure level (SPL) meter such as the Goldline
SPL120 or the Radio Shack Realistic 33-2050, and set the meter for
“C-weighting” and “Slow” response.
With the meter at the listening position being defined, and
pointing straight up at the ceiling so as to avoid favoring one
Nº40 Media Console Menu System
speaker over another, adjust the output levels of each speaker in
turn to 75 dB SPL (C-weighted, slow). (The Nº40 will automatically
generate appropriate test signals when you move into the section of
the menu in which you can adjust output levels.)
When adjusting the subwoofer level, be sure to move the meter
back and forth around the listening position by at least a foot or
more (or about a half-meter) to average out the local effects of room
modes (standing waves). Doing so will give you a more accurate
measurement of the real subwoofer output in the listening area.
Boundary gain compensation
If your listening position results in most of the listeners being close
to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that the overall sound quality becomes
boomy. If this is the case for this particular listening position, turn
BCG on. If not, leave it off.
Disable this position
Bass Peak Limit
Four listening positions are more than you will probably need. This
option allows you to disable any unused listening positions so that
they do not show up in any lists or menus. Listening position one
cannot be disabled.
5-17
The last item in the speakers setup menu is a bass peak limit
control. This menu item establishes a maximum volume setting for
the subwoofer output, and is provided as a safety measure against
the possibility of overdriving your subwoofer into destruction.
Some powered subwoofers have built-in protection against overload, or have amplifiers designed to be incapable of destroying the
subwoofer driver itself. If your system employs this sort of protection, leave the bass peak limit at its maximum (and therefore
effectively disabled) setting. After all, the speaker designer knows
the limitations of his/her product better than either you or we can.
It is best to let the speaker designer decide.
However, many subwoofers lack any protection against being overdriven, other than your own discretion in using the volume
control. While this discretion is always a good thing – if your
system starts to sound distorted, “fuzzy” or garbled at high
volumes, turn it down! – some people might prefer to have the
system itself provide a measure of additional protection. This task
falls to the bass peak limit item of the speaker menu.
In discrete multichannel digital audio, it is possible to have six (or
more) channels of information that contain deep bass information.
In many cases, the only speaker in the system that can reproduce
deep bass is a single subwoofer. If one subwoofer is expected to do
the work of six speakers, and the listener-controlled volume is
Menu System Mark Levinson
turned up fairly high, it is easy to imagine the woofer being taken
beyond its limits.
With the bass peak limit control, you are given an opportunity to
establish a maximum volume beyond which you do not want your
subwoofers to go. If you are reasonably judicious with your main
volume control during listening, you do not have to perform this
adjustment at all. It is provided to give you the option of imposing
an artificially low upper limit on bass transients (explosions, etc.),
without affecting the perceived balance of bass at normal volumes.
1. Enter the bass peak limit menu and choose test signal: enabled.
You have the option of setting the bass level manager volume
level arbitrarily, without the benefit of listening to a test signal;
or by listening to a low-frequency (bandwidth-limited) pink
noise signal through the subwoofer(s). After experimenting
with the bass level manager, you might want to reset it to its
maximum setting (effectively disabling it). This would be best
done without having to endure an extremely loud test signal
(e.g., test signal: disabled).
5-18
When you choose to use the test signal by changing test signal:
from disabled to enabled, the low frequency test signal will be
sent to your subwoofer(s) at a modest volume, when you enter
the adjustment item on the menu. (The adjustment is made on
the next item down on the menu from test signal: enabled/
disabled.)
Regardless of the previous setting, the initial setting of the bass
level manager when you enter its menu is a low value. This is
done to avoid a sudden, potentially speaker-endangering level
of the test signal being sent to your subwoofer(s).
2. Raise the volume of this test signal to the loudest level you are
likely to want to hear from your subwoofers, being careful not
to overdrive them.
This is a potentially tricky area, since you don’t want to limit
the performance of your subwoofers unnecessarily. At the same
time, neither do you want to overdrive them during the calibration of the system! (One way out: have your dealer do the calibration, since he or she is more familiar with the capabilities of
the speakers you purchased.)
3. Save this volume setting.
Save the setting by pressing enter, which also disables the test
signal and resets its next turn-on level to a low level. (This last
step on the Nº40’s part ensures that the test signal always starts
out at a modest volume.)
Nº40 Media Console Menu System
Sound Profile Menu
This section of the Nº40 Setup Menu allows you to create customized sound profiles that suit your needs. Once defined, you can
cycle through them using the profile button on the remote control
or the sound profile button on the audio processor’s front panel.
People often want to adjust their multichannel audio systems a bit
differently, depending on the material to which they are listening.
For example, when watching an action movie you may want to
exaggerate the surround and subwoofer channels a bit to make it
even more exciting. Yet, when you listen to music, the same “exaggerations” sound artificial and objectionable.
Similarly, you may prefer to use Dolby Pro Logic II & THX when
watching a Dolby Surround encoded movie (that has a two channel
sound track), but you may prefer the stereo surround mode for
listening to two channel classical music.
Simple, one-time adjustments of this sort can be made by using the
balance and the surround mode controls, as described in “Audio
Processor Front Panel” on page 2-7. However, you may find that
your adjustments are more extensive, and/or done more regularly.
If so, you can define a sound profile that will reconfigure your
system to your preferences either at the touch of a button or
automatically.
5-19
Name
You can also associate any defined sound profile with either a
particular input, or with a particular type of audio signal. These
options are discussed in “The Define Input Menu” on page 5-31
and “The Audio Defaults Menu” on page 5-42.
This powerful concept allows you to reconfigure the Nº40 for
particular uses, quickly, easily, and (at your option) automatically.
You can always override any automatic selection of a sound profile
by pressing the profile button on the remote control or the sound
profile button on the audio processor’s front panel. Up to twenty
sound profiles can be defined and used (though you may want to
limit the number you use, to keep the list more manageable).
Note that if you edit and save a sound profile while it is active, your
changes will be reflected beginning the next time that profile is
selected. Sound profiles are designed to provide automatic, intelligent “initial defaults” for different activities, without preventing
you from making manual changes. For that reason, they are triggered only by other actions: manual selection, input selection, or
the detection of a new signal. They do not “lock you into” a certain
mode of operation.
The name can be up to twelve characters long (e.g., “main chair,”
“couch,” “desk”). You enter the name with the keyboard window as
follows:
Menu System Mark Levinson
1. Select the name menu item.
2. Press enter (or right arrow, on the remote).
Invokes the keyboard window. The current name is displayed in
the Name Line with a blinking cursor on the currently active
character. A keyboard with characters and operations to select is
shown with one highlighted character
3. Rotate the zone knob and the input select knob (or use the up/
down arrows on the remote) to move the highlight to the
desired character or operation and press enter to select it
The selected character will be added to the Name Line at the
cursor, and the cursor will move one space to the right.
The following operations are available to complete editing the
name:
• insert Adds a space at the cursor position
5-20
Listener Position
• del Deletes the current cursor position
• clear Clears the entire Name Line
• cap Toggles the characters between capital and small letters
• save Saves the current Name Line and returns to the menu
• quit Returns to the menu without saving the Name Line
• ––> Moves the cursor one space to the right
• <–– Moves the cursor one space to the left.
4. Repeat steps 1 - 3 to fill in the name.
5. To end the editing session, select save or quit. The menu button
also performs the quit operation directly.
The first characteristic of a sound profile is selecting a defined
listener position, discussed previously in The Speakers Menu. For
example, you watch movies from one chair in the room, but you
may enjoy listening to music while reading in a different chair with
better lighting. If you define different listening positions for each
location, you could create a “Reading” sound profile that would call
up your preferred listening position.
This menu item lists all the defined listener positions. If you decide
you need a new one, simply go back to the speakers menu and
create it; it will appear in the sound profiles menu the next time
you enter it.
Select the listener position that makes the most sense for the
activity for which you are creating a sound profile. If you would
prefer to control your listening position manually, choose no
Nº40 Media Console Menu System
change. The profile will then make no change to the current
listening position. If all of your profiles are set to no change, then
the Nº40 will power up to the first listening position and the
listening position is only changed in the audio controls menu or
through a direct command.
Multichannel Signal
The multichannel signal menu item describes what (if any) further
processing you would like to have applied to a discrete multichannel signal such as Dolby Digital 5.1, DTS 5.1, AAC 5.1 or MPEG
5.1, when you are in this particular sound profile.
When receiving and decoding a multichannel signal, allowable
surround modes depend on the number of back speakers you have
defined and the particular input signal being decoded. The
following surround modes are available.
•Downmix (2ch)
Downmix the multichannel signal to a 2-channel signal for
reproduction on the left and right front speakers.
• Multichannel
Signal passes through with no processing.
•THX Cinema
5-21
Engage THX processing for movies.
• Surround Plus
This surround mode is only available if there are one or two
surround back speakers defined. If there is one back speaker,
then it gets a scaled sum of the surround channels (sl or sr). If
there are two back speakers, the left surround back speaker gets
a scaled version of the left surround and the back right speaker
gets a scaled version of the right surround. It is not available for
six channel streams (Dolby-EX or DTS-ES).
• Surround Plus + THX Cinema
Add THX cinema processing to above.
• Surround Matrix
Use DTS NEO:6 matrix processing to create surrounds and back
channels from the surround left and surround right channels. It
requires one or two back speakers.
• THX Surround EX
Use Dolby Pro Logic II matrix processing to create the
surrounds and back channels from the surround left and
surround right channels. Add THX cinema post processing. If
the multichannel signal is DTS, then DTS NEO:6 is used instead
Menu System Mark Levinson
of Dolby Pro Logic II and the mode is called Surround Plus +
THX Cinema. One or two surround back speakers are required.
•THX Ultra2 Cinema
Use THX Advanced Speaker Array technology to create the
Surround and Back channels from the surround left and
surround right channels. Add THX cinema processing including
RE-EQ, Timbre Matching and Adaptive Decorrelation. Two back
speakers are required and it is not available for six channel
streams (Dolby-EX or DTS-ES).
•THX Music Mode
Uses THX ASA processing to provide a wide stable rear soundstage for multichannel music. Two surround back speakers are
required and it is not available for six channel streams (DolbyEX or DTS-ES).
• Surround Redirect
The surround channels are sent to the surround back speakers
and the primary surround speakers are turned off. Two
surround back speakers are required and it is not available for
six channel streams (Dolby-EX or DTS-ES).
5-22
2 channel signal
If the input stream is a Dolby encoded stream with the EX flag set
indicating that it contains back channel information, THX
Surround EX mode will be automatically engaged and your choices
will be limited to Downmix, Surround Matrix or THX Surround EX.
If the input stream is a DTS encoded stream with the ES flag set
indicating that it contains back channel information, it will default
to Multichannel or THX Cinema depending on whether a THX
mode was indicated in your profile. Manual setting choices will
then be limited to Downmix, Multichannel or THX Cinema.
If the input is a six channel analog input or DTS 96/24, the
Surround Matrix mode and all THX modes cannot be used. If an
invalid mode is called for in the profile, its closest valid mode will
be selected automatically. If the invalid mode contained back
channel information, the new mode will be Surround Plus. If not,
the new mode will be Multichannel.
This menu item describes any further processing you would like to
apply to a two channel signal such as 44.1 kHz PCM from a CD,
Dolby Digital 2.0, or MPEG 2.0, when you are in this particular
sound profile.
There are significantly more options available for processing most
two-channel signals than for processing multichannel signals. This
makes sense when you think about it, since most of the options for
two channel signals are different ways of processing the two
channels to use most or all of your speakers.
Nº40 Media Console Menu System
The Nº40 provides a variety of processing options for two channel
material. They include:
•2-ch Stereo
Used to play the two-channel signal in its native state through
the front left and front right speakers. Note that if you have
specified a crossover and subwoofer, it will still be used in this
mode. (You can change this as another part of the sound
profile.)
• Stereo Surround
Used with music to extract ambient information contained in a
recording, and to place that information out in the surround
speakers where it belongs. The front left and front right channels remain unprocessed, and a slight amount of center-fill
information is added to widen the effective listening area. This
is a relatively subtle effect that strives to be as natural as possible rather than have a striking effect.
• Mono Center
The mono signal is formed by summing the left and right channels. The result is sent out the center speaker only.
• Mono on Front Speakers
The mono signal is formed by summing the left and right channels. The result is sent out all three front speakers (L,C,R).
• Mono Surround
The mono signal is formed by summing the left and right channels. This mode uses all available loudspeakers to add some
additional ambience to create a larger sound field.
•Dolby Pro Logic
Used with specially encoded two channel recordings, correctly
called “Dolby Surround” recordings, but often called “Pro Logic
encoded” recordings. Although some Dolby Surround music
recordings exist, the large majority of Dolby Surround recordings are films created after 1976. (Note that most of these films
will sound better when reproduced with the addition of THX
post-processing.)
•Dolby Pro Logic with THX
5-23
The same decoding as above, but with the addition of THX post
processing: re-equalization of the front channels, and decorrelation and timbre-matching of the surrounds.
• Dolby Pro Logic II Movie
Can be used with either music or movies (though again, most
movies benefit from THX as well); it even works well with mate-
Menu System Mark Levinson
rial that was not specifically encoded for Dolby Pro Logic playback.
• Dolby Pro Logic II Movie with THX
The same decoding as Dolby Pro Logic II Movie, but with the
addition of THX post processing: re-equalization of the front
channels, and decorrelation and timbre-matching of the
surrounds.
• Dolby Pro Logic II Music
This mode is a specific permutation of the Dolby Pro Logic II
system that is optimized for multichannel playback of twochannel music material that has not been specially encoded in
any way.
• NEO:6 Cinema
Provides up to six full-band channels of matrix decoding from
stereo matrix material
5-24
Mono Signal
Note Mono material is sometimes released as a two-channel recording,
• NEO:6 Cinema with THX
The same decoding as NEO:6 Cinema, but with the addition of
THX post processing: re-equalization and timbre matching
filters.
• NEO:6 Music
Expands stereo non-matrix recordings into the five- or sixchannel layout in a way which does not diminish the subtlety
and integrity of the original stereo recording.
As of today, the only truly “mono” digital signal that exists is Dolby
Digital 1.0, a mono version of the Dolby Digital standard. It is most
commonly used on old movies that were originally released in
mono, such as The Wizard of Oz or Casablanca.
where both channels are exactly the same. The signal itself is still in a
two channel format, however, and will be processed as such even
when there is only one channel of unique information being
conveyed.
Your processing options for one channel/mono material include:
• Mono in Center
A “true” mono, reproduced only through the center channel
speaker (and subwoofer, if configured with a crossover). Noisy
mono sound tracks sometimes enjoy significant noise reduction
by being reproduced in this mode.
Nº40 Media Console Menu System
• Mono on Fronts
Places the same mono information in both the left and right
speakers, creating a “phantom” center image that some people
prefer to using the center speaker only.
• Mono Surround

The solution makes use of some specific information provided by
Dolby Digital sound tracks to provide some degree of compression
to reduce the dynamic range to something more appropriate to the
environment. Since this feature depends on information only available within Dolby Digital sound tracks, it is only available when the
Nº40 is decoding Dolby Digital.
Your sound profile options for the Dolby Digital Compression
feature are:
• None (no compression)
• Mild (slight compression of the recording’s dynamic range)
• Medium (moderate compression of the recording’s dynamic
range)
• Full (maximum compression of the recording’s dynamic range).
5-26
Front L/R High Pass
Filter (HPF)
The front L/R high pass filter specifies the frequency above which
information is passed to the front left and right loudspeakers.
The normal, or default, setting for these speakers is established in
the speaker menu, and should represent the way you want to use
the system most of the time (if not always). However, there may be
special applications where a different crossover setting would be
preferable. For example, if you have full range speakers that you use
for the front left and front right, it may make sense to cross them
over to a subwoofer for most multichannel material, if the
subwoofer has superior dynamic range capabilities. But you may
prefer to run the front left and right speakers full range for simple
two-channel recordings, played in 2-channel stereo mode. This
would effectively turn off the subwoofer and change the Nº40based multichannel system into a high quality stereo system.
The options for changing the stereo high pass filter for a particular
sound profile include:
•Normal
The default setting for new profiles, and the same as you have
described in the speaker menu.
•Full range
This effectively defeats the crossover as far as the front left and
front right speakers are concerned.
• Full range with subwoofer
Provides for “redundant” bass below 50 Hz, as the front left and
front right speakers will be full range while the subwoofer will
also operate below 50 Hz.
Nº40 Media Console Menu System
• 30-100 Hz
A normal, complementary crossover, available in 10 Hz increments.
In the normal setting, your subwoofer will reproduce whatever the
main front stereo speakers are not reproducing. For example, if you
change the crossover for the front left and front right speakers to 40
Hz, the subwoofer will reproduce front left and front right information below 40 Hz.
When the main speakers are set to full range in 2-channel stereo
mode, no information is sent to the subwoofer.
Full range with sub allows the subwoofer to reinforce a “full range”
main set of speakers that might in fact have reduced output below
about 50 Hz (a surprisingly common problem).
The best solution for such problems is usually to lower the crossover frequency to something consistent with what the main
speakers can actually do, perhaps to 30, 40, or 50 Hz (depending on
the speakers and the room). This is the function of the 30-100 Hz
settings.

The surround modes for Dolby Pro Logic II music and DTS NEO:6
music have settings that can be adjusted to suit your taste. THX
cinema processing can also be adjusted. The Nº40 allows you to
define a set of all of these adjustments in each profile.

•Center Width
The center width control allows variable adjustment of the
center image so it can be heard only from the center speaker
(most narrow); only from the left/right speakers as a phantom
image (most wide); or from all three front speakers to varying
degrees. The default setting of neutral applies a small amount of
“width” to the center signal, which improves the blending of
the center speaker with the main speakers.
•Dimension
A simple control that alters the ratio of L+R to L–R for the 2channel input signals. It allows the user to gradually adjust the
soundfield either towards the front or towards the rear. If a

Delete This Profile
Add New
You can create a sound profile and subsequently decide to eliminate
it. Or you may want to delete one of the factory-default sound
profiles we provide as suggestions in order to help you get started.
If so, enter that profile’s submenu and select the following menu
item:
>>>>Delete this profile<<<<
will be asked to confirm your decision to delete the sound profile. If
you are sure you want to delete this profile, press enter to confirm.
If you prefer to think about it before deleting it, press menu to
cancel the action. (You can always re-create the sound profile if you
make a mistake.)
At the end of the list of all the profiles that have already been
defined, you will find one more menu item under the Profile menu:
Add new
You can create as many as twenty sound profiles to handle various
ways in which you would like to use your system, though you
should avoid creating more than you really need. Remember: you
can always make ad hoc changes in things like balance, delays,
surround modes, and so forth. The sound profiles merely provide
initial default conditions that are usually suitable to a variety of
different situations. Having too many of them can make it harder
to keep track of which one you actually want at any point in time.

Nº40 Media Console Menu System
The Define Input Menu
As can be seen from the rear panel diagrams and explanations
earlier in this manual, the Nº40 Media Console includes a plethora
of connectors and options for hooking up source components. The
Define Inputs menu specifies how you want to use the available
hardware, and gives you several powerful options designed to make
daily operation of the system simpler and more intuitive.
When you first enter the Define Inputs menu, you will see a list of
any and all inputs that have already been defined, along with the
last item, which allows you to add new inputs beyond those already
defined. When you highlight any particular input definition, you
can see all of the subordinate settings associated with that input,
along with a menu item that allows you to delete any input you no
longer need.
The parameters for each input that you can specify are as follows.
Name
The name can be up to twelve characters long (e.g., “main chair,”
“couch,” “desk”). This name is entered with the keyboard window.
To do so:
1. Select the name menu item
5-31
2. Press enter (or right arrow on the remote). This brings up the
keyboard window. The current name is displayed in the Name
Line with a blinking cursor on the currently active character. A
keyboard with characters and operations to select is shown with
one highlighted character
3. Rotate the zone knob and the input select knob (or use the up/
down arrows on the remote) to move the highlight to the
desired character or operation and press enter to select it
The selected character will be added to the Name Line at the
cursor, and the cursor will move one space to the right.
The following operations are available to complete editing the
name:
• insert Adds a space at the cursor position
• del Deletes the current cursor position
• clear Clears the entire Name Line
• cap Toggles the characters between capital and small letters
• save Saves the current Name Line and returns to the menu
• quit Returns to the menu without saving the Name Line
• ––> Moves the cursor one space to the right
• <–– Moves the cursor one space to the left.

4. Repeat steps 1 - 3 to fill in the name.
5. To end the editing session, use the save or quit operations. The
menu button also performs the quit operation directly.

Audio
The audio parameter defines which audio connection (or connections) you want to associate with this particular input. There are
some cases in which you may need more than a single audio
connection from a source component to the Nº40. You can associate up to three input connectors with a single input definition. In
so doing, you also establish the priority of connection, with the
first input listed having the highest priority, followed by the
second, followed again by the third.
You can also assign a function key or toolbar to a direct command
that will force the Nº40 to migrate to the next type of input and
suspend the automatic migration. Automigration will resume when
the input is changed, the Nº40 is put in standby, or the recall
button is pressed.
Since there are so many connectors on the rear panel of the Nº40, it
could be difficult for some people to remember “which wire was
connected where.” We have done several things to make this
simpler for you.
First, you will find rear panel hookup charts at the back of this
manual, which we suggest you copy and use when hooking up the
system. Take notes as to what source components are connected to
which input connectors. These notes will be quite helpful later,
when you are in the Inputs menu.
Second, we have provided a graphical user interface (GUI) for
defining these connections, one that depicts the rear panel of the
processor in question. For many people, this visual depiction of the
rear panel is what they need to sort things out.
Lastly, we also specify input connectors verbally by a simple “slot &
connector” system. The slot numbers are engraved along the edge
of the top cover of each processor, and the connectors are
numbered from top to bottom on each card. Thus “slot 3,
connector 4” is the fourth connector down on the card sitting in
the third slot from the left, as seen from the rear of the unit.
To specify the particular connector(s) you wish associated with an
input:
1. Select the audio menu item
2. Press enter (or right arrow, on the remote). You will see a list of
three possible audio inputs
Nº40 Media Console Menu System
3. Rotate the zone knob (or use the up/down arrows on the
remote) to select the audio input (first, second or third priority)
that you want to define or edit
4. Press enter (or right arrow, on the remote) to select that input
for editing.
You will see a graphic of the rear panel of the audio processor,
complete with all installed input cards. Connected inputs will
be highlighted in blue, and the currently active input will be in
yellow.
5. Rotate the zone knob and the input select knob to navigate the
yellow highlight around the inputs.
Informational text will describe the currently highlighted
input. You can also de-assign the input or quit to leave the
input unchanged.
6. Press enter to save the currently highlighted input and return
to the audio inputs menu.
Pressing the menu button quits the operation.
Note You can associate the same physical connector with more than a single
input.
RF Adjust
If one of your connectors is an RF demodulator, you must calibrate
that input with your Laser disc player with the following procedure.
1. Connect the RF out of the Laser disc player to the connector on
the RF demodulator card. Play a disc that has an AC-3 track.
2. Enter “RF Adjust” and use the zone knob or the up/down navigation keys on the remote to adjust until errors = 0.
3. Press enter to save the new value.
Video
The method for defining which of the many video inputs is associated with a particular input is similar to the method used for audio,
with one important exception: there is only one video connection
supported per input.
5-33
When you enter the video connection portion of the input menu,
you will see a similar user interface for defining these connections,
one that depicts the rear panel of the processor in question. For
many people, this visual depiction of the rear panel is what they
need to sort things out.

One of the most powerful uses of the sound profile capability of the
Nº40 is to associate a default sound profile with an input. You can
always override this default profile, but used intelligently, this
feature can largely automate the reconfiguring of the system to suit
different situations. This will be discussed in more detail later, in
the “Advanced Features” on page 7-1.
If you would like to automatically switch to a particular sound
profile whenever you select the input you are defining, select it
from the list of profiles provided here. Of course, you cannot select
a profile that has not yet been defined; this is why the sound profile
menu comes before the inputs menu. (Naturally, you can jump
back and forth between the menus as needed to get the job done.)
