Unpacking and Placement
Unpacking the Nº37 Unpack your Nº37 CD Transport and remove all accessories from the carton.
Important! Keep all packing materials for future transport of your Nº37.
Shipping your new component in anything other than its
purpose-designed packing material may result in damage
that is not covered by the warranty.
Included with your new Mark Levinson product is a pair 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
one of our products.
Remove the Transport Screws Place the Nº37 CD Transport upside-down on a soft, clean surface. Remove the
transport screws from the bottom of the unit and save them with the packing
materials for future use.
Warning! The transport screws must be removed before operating the
Nº37, since they immobilize the transport mechanism during
shipping to prevent damage. These screws must also be
replaced before shipping the unit.
Placement of the Nº37 The Nº37 should be placed close to your digital audio processor, thus keeping
interconnect cabling reasonably shor t. It may be placed on a shelf or in a cabinet
where it is convenient to operate, but should not be rack mounted, so as to leave
access to the rear panel power switch.
The Nº37 is designed for continuous operation—hence the standby button on
the front panel rather than a power button. However, a rear-panel power switch is
provided for your convenience should you want to disconnect the unit from the
AC mains (as when taking a vacation, for example).
Be sure to allow 3 to 4 inches of clearance above the Nº37 to allow heat dissipation through air circulation.
Drawings are included in this manual to facilitate special installations and custom
cabinetry (see Dimensions).
6
Operating Voltage
& Frequency
The Nº37 CD Transport is set at the factory (internally) for 100V, 120V, 200V, 220V,
or 240V AC mains operation as appropriate for the country in which it is to be
sold. Make sure that the label on the rear of the Nº37 (adjacent to the power
cord) indicates the correct AC operating voltage for your location, as attempting to
operate the Nº37 at an incorrect voltage can damage the unit. (Note that only
230V units are sold in the European Union countries, per CE requirements.)
The Nº37 CD Transport is also set at the factory for operation on either 50 or
60 Hz AC line frequencies, as appropriate for the country in which it is to be
sold. It will not operate if it senses an incorrect line frequency.
Warning! Neither the voltage nor the line frequency setting may be
changed by the user. There are no user serviceable parts
inside the Nº37. Only qualified, authorized service personnel
may open the Nº37 CD Transport, as hazardous voltages exist
within the unit.
If the AC mains voltage or frequency indicated on your Nº37 is incorrect, please
contact your local, authorized Mark Levinson dealer or distributor.
The Nº37 can easily be powered by a normal 15-ampere AC mains line. If other
devices are also powered from the same AC line, their additional power consumption should be taken into account.

A Quick Start…
We recognize that many people are understandably eager to begin listening to
their new components, and that reading the manual is often done (if at all) at a
later time—perhaps while listening to music with the new product itself. We
strongly recommend that you read this manual thoroughly, as the Nº37 CD Transport incorporates many unusual features that enhance its operation.
Fortunately, we can help you get some music up and running on your system
quickly, so that you may begin enjoying your new CD transport while reading
more about it. The goal here is simply to make some music as quickly as possible. The following procedure assumes that the rest of your system is already
connected (e.g., digital processor to preamplifier, to power amplifier, to speakers,
etc.).
1 TURN OFF YOUR ASSOCIATED COMPONENTS
This minimizes the opportunity for a momentary electrical surge disturbing
your system while making connections. If you have a large power amplifier,
allow its power supply to fully discharge before proceeding (which may
take as long as several minutes, depending on its design).
2 REMOVE THE TRANSPORT SCREWS FROM THE BOTTOM OF THE Nº37
If you have not done so already, remove the slotted transport screws from
the bottom of the Nº37 now. Be sure to save them and all packing material
for possible future use. (Shipping the Nº37 without proper packing material
and without the transport screws in their proper positions may cause damage to the unit that would not be covered by the warranty.)
3 CONNECT THE Nº37 TO AC POWER
Connect the AC cord to the Nº37 at the receptacle on the rear panel, and
then to your AC outlet. Then turn on the power switch just above the AC
power receptacle. (The international symbol for “on” is a single vertical line:
|. “Off” is symbolized by a circle: O.) The Nº37 will take a few moments to
initialize and will then be ready to use.
4 CONNECT A DIGITAL OUTPUT TO A MATCHING DIGITAL INPUT ON YOUR
PROCESSOR
The Nº37 supports a variety of types of digital outputs to ensure compatibility with any digital processor you might wish to use. These digital outputs are found on the rear of the Nº37. Madrigal has found that, when fully
optimized at both ends, the AES/EBU professional digital interconnection
standard is the finest available. Depending on your processor, however, you
may find that a different interface is best in your system. It is important to
use high quality digital cable such as Madrigal MDC-1 for AES/EBU (via
XLRs), or MDC-2 for S/PDIF (via RCA or BNC) connections.
8
5 POWER UP THE REST OF THE SYSTEM, LEAVING THE POWER AMPLIFIERS
FOR LAST
Always turn the power amplifer(s) off first, and on last. This good habit
minimizes the opportunity for unexpected transients to be passed to your
loudspeakers.
6 SELECT THE INPUTS YOU ARE USING ON YOUR DIGITAL PROCESSOR
AND PREAMPLIFIER
Take care that a Tape Monitor switch does not override your selection of
the digital processor’s input on your preamplifier, or you will be struck by
how “quiet” your new digital source is.…
7 LOAD A DISC IN THE DRAWER AND PRESS PLAY; SLOWLY RAISE THE
VOLUME ON YOUR PREAMPLIFIER
Congratulations! You should now be able to enjoy your favorite music while
reading the rest of this manual. (Please, do read the rest of this manual.)
Warm up/break-in period Although your Mark Levinson Nº37 CD Transport delivers outstanding perfor-
mance 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 few hours as the Nº37 reaches thermal equilibrium. Depending on how cold
the Nº37 was when you first connected it to AC power, full thermal equilibrium
might take as long as a day or two, after which time its performance will remain
quite constant.
The only exception to this rule is if power is removed from the unit for more
than a few minutes, allowing it to cool down. Depending on the degree of cooling involved, you should expect a brief warm-up period before the Nº37’s sound
quality is at its best. Unless your Nº37 was allowed to become quite chilled, subsequent thermal re-stabilization should not take long.

Special Design Features
Congratulations on your purchase of the Nº37 CD Transport. The Madrigal design
team is confident you will enjoy the outstanding performance of the Nº37 for
many years. In case you are interested in technical details, what follows is a brief
outline of some of the key technologies in your new transport.
A New Generation The characteristics of an outstanding CD transport are simple to define: it must
recover the correct data from the disc, and deliver it to the digital processor without any timing errors (sometimes called “jitter”). As simple as this sounds, achieving it in reality has been extremely difficult—as evidenced by the significant
sonic differences between various CD transports.
Conventional CD transport design depends on the quality of the oscillator used
to control the rate at which the disc itself spins. This oscillator exists in an extremely “noisy” electrical environment close to the motor that spins the disc. The
electrical noise introduces timing errors in the delivery of the digital signal that
have come to be known as “jitter.” Subsequent handling of the digital audio signal in traditional transport designs cannot improve upon this “jittery” signal, lacking a better reference. To the contrary, the various stages of signal processing between the laser pickup and the final output can only contribute additional jitter of
their own.
The Mark Levinson Nº37 leaps beyond conventional digital audio technology by
employing a proprietary, closed-loop jitter-reduction system in conjunction with a
double speed CD-ROM drive. Using a custom-made crystal oscillator with better
than five part-per-million accuracy, the digital signal is reclocked immediately before the output, eliminating transport-related jitter from the digital audio signal.
This same crystal oscillator controls the all-digital servo used to control the rate
at which the disc spins.
In effect, the design of the Nº37 turns the accepted status quo on its head. By
placing the all-important reference clock in the final stage of the transport’s out-
put section, and slaving the mechanical subassemblies to it rather than the other
way around, the signal presented to the outputs of the Nº37 is uncontaminated
by electrically- or mechanically-induced jitter. The sonic advantages of this design
are immediately apparent in the clarity, warmth and stunning dynamic contrasts
exhibited by the Nº37.
Digital Servo Control The laser mechanism used in the Nº37 uses all digital servo controls of its opera-
tions. Critical functions such as focus and tracking are handled completely in the
digital domain with mathematical precision. Whereas conventional, analog servos
require periodic realignments for optimum performance (to compensate for the
aging of various analog components), a digital servo remains stable over time,
never needing readjustment under normal conditions.
10
Output Versatility All high quality digital output configurations are supported in the Nº37. A new
complementary driver for the balanced AES/EBU electrical output delivers outstanding performance to the high quality XLR connector. Single-ended S/PDIF
electrical outputs are provided via both BNC and RCA connectors, and the ST
optical output uses a high-bandwidth Hewlett Packard® part for superior performance.
All digital interfaces have been carefully optimized to deliver the finest performance each interface standard allows. As a direct result, the Nº37 performs optimally with any digital processor, without having to resort to techniques which
would limit its compatibility to other Mark Levinson products.
Industrial Design The Nº37 shares the handsome industrial design of other Mark Levinson compo-
nents such as the Nº36 digital audio processor. The combination of the handbrushed, black-anodized aluminum faceplate and bead-blasted custom-machined
buttons make operating the Nº37 a tactile as well as a sonic pleasure.
A large, easily read display provides information as to the operational status of the
Nº37 from across the room, making the supplied remote control more genuinely
useful than on products lacking such a display.
In keeping with its sophisticated design, the Nº37 also incorporates a Madrigaldesigned loading mechanism. Contrasting strongly with the bulky, plastic drawers
commonly used, the slim 1⁄8 inch drawer is machined from a solid piece of aluminum and rides on highly polished bearings. Its variable-speed design opens and
closes quickly, but without jarring the disc contained within, nor risking a jam
from dislodging it.
Convenience Features Too often, high performance CD transports have eschewed convenience in the
hopes of seeming more “performance-oriented.” While there were good arguments for such a “minimalist” design in the days of analog turntables, the time is
long gone when the audiophile needed to give up operational convenience for
musical performance. After all, convenience features in a digital product are
largely a matter of writing appropriate software, and have no affect on the quality
of the digital data itself.
The Nº37 also supports custom programs, including “delete programming”
wherein selected tracks are omitted from the playlist. This allows the user to skip
the one or two songs on an otherwise good disc that have been overplayed ad
nauseam. The Nº37 will remember such programs for thousands of discs, should
you want to save that many programs.
Communications Links As with all Mark Levinson 30-series components, the Nº37 incorporates a sophis-
ticated inter-component communications bus. Unique among high performance
audio systems, Mark Levinson 30-series components offer a degree of system integration that makes even complex systems easy to use.
For example, bringing the Nº37 CD transport out of standby will also bring the
Linked digital audio processor, preamplifier and power amplifier(s) out of
standby, and select the appropriate inputs on both processor and preamplifier so
that a CD can be enjoyed. Even a sophisticated system with any components can
thus offer one-button simplicity of operation.
In short, the Mark Levinson Nº37 establishes a new standard for performance and
practicality among high end CD transports and should be auditioned by anyone
who desires the finest in digital audio.

When power is first applied to the Nº37 (or when power is restored after
an interruption), the display is automatically set to its brightest level.
Pressing the display intensity button once dims the display one level; pressing it again dims it further; pressing it again turns the display off. Pressing
display intensity once more returns the display to its brightest level. (If
other Mark Levinson components in the system are “Linked” to the Nº37, all
display intensities can change in unison. See Linked Functions for more information.)
If the display is set to “off”, pressing any key will cause it to light at medium
intensity for approximately four seconds in order to display the action of
the key press.
2 INFRARED TRANSCEIVER (WITHIN DISPLAY)
Infrared commands transmitted from the remote control are received by a
receiver behind this section of the display. Remote control of the Nº37 may
be unreliable if there is not a clear line of sight between the remote control
and the receiver (if the remote is far off-axis, or if the Nº37 is within a cabinet, for example). In such a case consider using a third-party IR repeater to
route the signal to the IR input jack on the rear panel (see Rear Panel, Nº37,
below).
12
In addition to receiving IR commands, the Nº37 has the ability to teach a
learning remote control its own commands from an IR transmitter located
in this same area. (See Using Learning Remote Controls for more informa-
tion.)
3 SPECIAL MODE INDICATOR
The first character in the display is reserved for indication of special modes
of operation. For example, a
gram
(a special sequence of tracks) is being played: A and B alternate
P is displayed in this space to indicate a Pro-
while an A-B loop is being repeated.
4 TRACK INDICATOR
The next two characters are used to indicate the number of the track being
played. When a compact disc is loaded but the transport is in the stop
mode, this same space indicates the total number of tracks on the disc (or
in the program for the current disc, if programmed).
5 TIME INDICATOR
The time section of the display can be set to display any of the following
four indications of time in minutes and seconds: time elapsed in track,
time elapsed on disc, time remaining on disc, time remaining on track.
These four options are accessed by pressing the mode button to the right
of the display (see 6, below), which cycles through the four modes of time
display, using the time on disc and time remaining LEDs to indicate which
mode is chosen at any moment. When in stop, the indicated time will always default to the total remaining time on the disc (or in the playlist for
the current disc, if programmed). This time indication may be changed if
desired once in stop.
6 MODE BUTTON
The mode button cycles through the four time display modes used to indicate where you are on the disc. These four display modes are:
• time elapsed in track (neither LED lit)
• time elapsed on disc (time on disc LED lit)
• time remaining on disc (time on disc and time remaining LEDs lit)
• time remaining on track (time remaining LED lit)
These four options are accessed by repeatedly pressing the mode button,
which cycles through the four modes. In effect, the Nº37 assumes you will
be most interested seeing elapsed time on the current track; only depar-
tures from that assumption are denoted by LEDs. The Nº37 will remember
the last display mode selected and continue to display that information until
you change it, except in stop (when it always defaults to showing the time
remaining on disc, or in the disc’s playlist if it has been programmed). If
desired, once in stop the time indication may be changed to show any of
the other display modes.
Along with program + and program –, the mode button is also used to
change the link settings. (See Linked Functions.)
13
7 REPEAT BUTTON
You may choose to either repeat the entire disc (including any programs
you might have entered for that particular disc) or an individual track by
pressing the repeat button. From normal operation, the first press of the
repeat button will cause the display to show RPT DISC momentarily, and
subsequently will light the disc repeat LED below the display (number 10
in the front panel illustration). Pressing the repeat button again will display
RPT TRK for a moment and then light the track repeat LED (number 12 in
the front panel illustration). Pressing it a third time will cycle out of any repeating mode, as will pressing stop/drawer at any time. In either case, both
repeat LEDs will be extinguished and the display will show RPT OFF for a
few moments.
8 DRAWER
The Nº37 employs an elegant, slim drawer that is machined from a solid
piece of aluminum. It is normally opened and closed by pressing the
stop/drawer button (number 14 in the front panel illustration). If opened, it
may also be closed simply by gently pushing the front edge inward (as
though you were going to close it manually). The Nº37 will interpret this as
a request to close the drawer and take over for you, smoothly closing the
drawer.
If the Nº37 senses an obstruction during opening of the drawer mechanism,
it will attempt to re-close. If successful, it will read the disc’s table of contents and display the disc’s number of tracks and total time (followed by
the playlist’s track and time information, if one exists). If for any reason the
drawer does not close fully, the display will show DRAWER to indicate the
problem. After removing the obstruction, press the stop/drawer button
again to close the drawer normally.
Similarly, if the Nº37 senses an obstruction during the closing of its drawer
(as might be caused by an improperly seated CD, or an inquisitive child’s
finger), it will stop immediately and attempt to reopen. If the nature of the
obstruction prevents this also, it will stop where it is and wait for your intervention, displaying DRAWER to indicate the problem. After removing the ob-
struction, press the stop/drawer button again to close the drawer.
9 PROGRAM – AND PROGRAM + BUTTONS
Using these two buttons, the Nº37 can be easily programmed to play a special “playlist,” or sequence of tracks, on any par ticular disc. Pressing pro-
gram +
adds a selection to a program.
Alternatively, it may simpler to omit the one or two songs that you have
heard too many times on the radio, playing the rest of the tracks in order.
Pressing program – will delete the selected track from the playlist, omitting
it on playback.
A program may be entered any time a disc is in the Nº37 and the unit is in
the stop mode. For detailed information on programming the Nº37, see Pro-
gramming the Nº37 later in this manual.
14
10 DISC REPEAT LED
This LED is lit when the Nº37 is set to repeat a disc (or a disc’s program, if
it has one) endlessly. This feature is accessed using the repeat button (see
number 7, above).
11 PREV/REW BUTTON
Pressing this button momentarily will return you to the beginning of the
previous track. Pressing and holding this button will instead perform a re-
duced-volume reverse scan of the music, reminiscent of the audible rewind
function found on many cassette decks. This scanning mode allows you to
quickly find a particular point within a track. (Incidentally, if you wish to
listen to the current track over again from the beginning, simply press play
while the track is playing.)
12 TRACK REPEAT LED
This LED is lit when the Nº37 is set to repeat a single track endlessly. This
feature is accessed using the repeat button (see number 7, above).
13 NEXT/F.FWD BUTTON
Pressing this button momentar ily will advance the Nº37 to the beginning of
the next track. Pressing and holding this button will instead perform a re-
duced-volume fast forward scan of the music, reminiscent of the audible
fast forward function found on many cassette decks. This scanning mode
allows you to quickly find a particular point within a track.
14 STOP/DRAWER
Pressing this button once while a disc is playing will stop the disc, resulting
in the total number of tracks and the total time on the disc being displayed.
(Both the time on disc and the time remaining LEDs are lit to clarify the
meaning of the information being displayed at this point.)
Pressing this button once the disc has stopped, or if there is no disc in the
transport, will cause the drawer to open. If the disc is still playing, you may
press the button twice rapidly, to effect both the stop command and the
drawer open command; the Nº37 will remember the second button push
and execute it as soon as the disc has stopped spinning.
Pressing the stop/drawer button will cause an open drawer to close. If it
senses a disc in the drawer, the Nº37 will take a moment to read the disc’s
table of contents so that it may display the total number of tracks and the
total time on the disc for your information. If a custom playlist exists for the
disc, the total number of tracks and the total time of the playlist is displayed
instead.
Finally, pressing and holding the stop/drawer button while the Nº37 is
stopped will display the version number of the operating software and its
checksum. This “hidden feature” allows you to double-check the version
number and integrity of the software in your unit without having to open it
up, should this ever become necessary.
15
15 TIME ON DISC AND TIME REMAINING LED INDICATORS
These LEDs are used to indicate which of the four available display modes
the Nº37 is in. The four indications of time that can be displayed are:
• time elapsed in track (neither LED lit)
• time elapsed on disc (time on disc LED lit)
• time remaining on disc (time on disc and time remaining LEDs lit)
•
time remaining on track (time remaining LED lit)
These four options are accessed by repeatedly pressing the mode button,
which cycles through the four modes. If a custom playlist exists for the current disc, time elapsed or remaining “on disc” refers to the playlist rather
than the entire disc.
16 PL AY BU TTON
As you might guess, press this button in order to play a disc. If a programmed sequence of tracks exists for that particular disc, the program will
be played from its beginning. Also, as you might expect, you may press the
play button immediately after placing a disc in the Nº37’s drawer; the
drawer will close and the Nº37 will enter the play mode as soon as it has
read the disc’s table of contents and checked to see if a program exists that
ought to be played.
The play button has another important function: if you wish to return to
the beginning of the track currently playing, simply press play to restar t at
the beginning of that same track. If the Nº37 is in pause, pressing play will
resume play.
Playing “Index 0” A few CDs have recorded sounds in the space immediately preceding the

Index 1, which is where the track is normally thought of as “beginning.”)

To change whether or not Index 0 is audible, press and hold the play but-
ton for a few seconds, until the display reads NDXØ OFF or NDXØ ON. To
toggle between on and off, click on the play button. When you have made
your selection, press and hold the play button again until the display reads
SAVED.

the extended pause mode After about two minutes in pause, the Nº37 will go into an “extended
pause” mode, showing X-PAUSE briefly in the display. Extended pause stops
the disc and turns off the laser against the possibility that you have been
called away and may not return for some time. The Nº37 will slowly flash
the double bars (") to indicate that you are in the extended pause mode
rather than normal pause.
