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.

If you plan to be away for an extended period, or have any other
reason to turn the system completely off, you can either unplug
your components, or use the power buttons on your various Mark
Levinson components.
When first connected to the AC mains, the audio and the video

If either or both units fail to enter standby normally, make sure that
both are turned on and the Nº40 communications cable is properly
installed between the two components.
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.
