Getting Started
About the No502 Media Console
Thank you for purchasing the Nº502 Media Console. True to the
Mark Levinson® tradition of home theater excellence, the superb
sound and broadcast-quality video processing capabilities of the
Nº502 Media Console are unsurpassed in today’s marketplace.
Product Description
The Nº502 Media Console features an intuitive interface with
user-configurable Activity list, separate audio and video profiles,
and independent speaker configurations. Profiles and Setups can be
configured and then assigned to multiple Activities, making setup
time shorter while providing maximum flexibility. With a wide
range of available audio and video input formats, multiple Activities
can be assigned to efficiently manage a wide range of media sources.
The fully automated calibration performs speaker distances and
levels calibration as well as Room Correction, which neutralizes
room modes, making all audio sources sound more accurate and
true to the original recording.
The large full-color front panel display, capable of producing
elegant bit-accurate graphics, allows access to the Nº502’s menu
system and can also be used in Preview mode. Preview mode
enables other video inputs to be viewed without disturbing the
current activity, providing an effective means to monitor multiple
inputs without disturbing the active video source.
The Nº502 features an extensive list of surround modes, including
Logic 7, Dolby, and DTS modes. To retain the purity of the audio,
the Nº502 has separate analog output cards for each channel and all
input/output connectors are isolated from the chassis to prevent
noise pickup from common impedance coupling. In addition, the
volume controls have been redesigned for improved noise
performance at lower volume settings while still preserving the full
digital depth of the audio.
The Nº502 contains state-of-the-art, broadcast-quality video
processing capability, enabling true-to-life colors, exceptional
detail, and deep blacks. In addition, the Nº502 uses
specially-designed motion adaptive video de-interlacing with edge
interpolation for both high-definition and standard definition
video sources. Advanced noise reduction and detail enhancement
circuitry cleans up and sharpens images degraded by compression
or analgo circuitry from such sources as standard DVDs and satellite
or cable broadcasts.

Mark Levinson Link2 functions are also supported.
The Nº502 Media Console is Mark Levinson’s finest processor to
date. The processing power and superb performance will simply
astound you, as will its simplicity and versatility, proving that this
product is the latest in a line of products that represent the very
best.

Getting Started
Installation Considerations
The Nº502 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
DO save all packing materials for possible future shipping needs.
DO inspect the Nº502 for signs of damage during shipment. If
damage is discovered, contact your authorized Mark Levinson
dealer for assistance in making appropriate claims.
DO locate and remove the accessory box from the carton. Make
sure it contains all of the items listed in the “What’s in the Box”
table on the previous page. If not, contact your authorized Mark
Levinson dealer.
Placement and
Ventilation
DO install the Nº502 Media Console on its own shelf for proper
ventilation.
DO install the Nº502 chassis on a solid, flat, level surface.
DO install the Nº502 Media Console close to associated
components to keep interconnecting cables as short as possible.
DO select a dry, well-ventilated location out of direct sunlight.
DO allow at least 3 to 4 inches (8 to 10cm) of clearance above the
Media Console for proper heat dissipation.
DO NOT place the Nº502 on a thick rug or carpet or cover the
Nº502 Media Console with a cloth, as this might prevent proper
cooling.
DO NOT expose the Nº502 Media Console to high temperatures,
humidity, steam, smoke, dampness, or excessive dust. Avoid
installing the processor near radiators and other heat-producing
appliances.
DO NOT install the Nº502 near unshielded TV or FM antennas,

Getting Started
Mark Levinson
DO NOT obstruct the IR (infrared) receiver/transmitter located on
the front panel display. The remote control must be in line-of-sight
with the front panel IR receiver. If strong sunlight or fluorescent
light shines on the IR receiver, remote control may be unreliable.
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” adapters. Doing so may cause
dangerous voltage to build up between components, which may
result in personal injuries and/or product damage.
Power Requirements
At the factory, the Nº502 Media Console is configured for 100, 120,
220, or 230-240 VAC power operation at 50Hz or 60Hz. Before
operating the Nº502, ensure that the power label on the rear panel
near the AC input connector indicates the correct operating voltage.
Caution!
DO NOT attempt to adjust the operating voltage. Consult a Mark
Levinson dealer if the operating voltage is incorrect or must be
changed for relocation purposes.
1-4
Different operating voltages may require the use of different
power cords and/or attachment plugs. Contact a Mark Levinson
dealer for additional assistance.
Operating States
Caution!
The Nº502 Media Console is designed for continuous operation and
has three operating states:
•

User Options
Customizing the No502
The Nº502 Media Console is customized through the Setup menu. The
Setup menu is organized to proceed through the setup process in a logical
manner. While nothing prevents the user from switching back and forth
between menu options, the simplest way of setting up the system is to
start from the top of the menu and work down. This is a particularly
useful approach since some of the early decisions affect the options
available in later menus.
The Setup menu contains the following submenus:
•
Displays – sets up video output parameters.
•
Speakers – sets up the speakers, crossovers, and calibration features.
•
Video Profiles – modifies the Video Profiles for the video
processing.
•
Audio Profiles – modifies the Audio Profiles for the audio
processing.
•
Activities – associates specific Profiles and Setups with each
individual activity.
•
User Options – sets up the general user preferences for system
parameters.
Setup of the Nº502 can be streamlined because of the Activity-based
nature of the menu structure. A number of common Activities have
already been set up at the factory and can provide a good starting place.
We recommend selecting the presets that most closely resemble your
system and then modifying them.
Add New, Name, & Delete
There are three commands that are available in every Display, Speaker,
Audio & Video Profile, and Activity menu in the Setup mode. These
commands – Add New, Name, and Delete – behave in the same manner in
every Setup menu.
Add New
The Add New menu option creates a new Setup, Profile, or Activity. When
selected, the Nº502 creates a copy of the current Setup, Profile, or Activity
and then saves the copy with a default name.

Customizing the Nº502
Deleting an existing Setup, Profile, or Activity is permanent and cannot
be recovered. It can, however, be recreated by using the Add New
command and making the modifications again.
Note
Setups and Profiles cannot be deleted if linked to an Activity. The Delete menu
option is grayed out and not accessible if the Setup or Profile cannot be
deleted.
Setup Step 1: Displays
The first decision you need to make is how many displays your home
theater system must support. For instance, you might want to use a front
projection system for watching movies but prefer to watch cable
television on a plasma display.
Create a new Display Setup for each display in your home theater
system. So, in the example above, you’d make two new Display Setups –
“Front Proj” and “Plasma”.
To create the new Display Setups:
1. Press Setup.
2. Select Displays and press Enter.
3. Select Add New and press Enter.
4. Select Name and press Enter.
5. Select the name of your new Display Setup using the Name Selector. If
required, refer to the “Name Selector” section at the end of this
chapter for instructions.
6. Select Save in the Name Selector and press Enter when finished
creating your new Display Setup name. The Nº502 saves the name and
opens the new Display Setup menu. Observe that the menu path on
the top of the screen indicates the new name.
7. Select Output Path and select the appropriate rear panel video output
connector for the Display Setup you just created.
8. If you are creating more than one new Display Setup, press the
button to return to Add New again.
9. Repeat Steps 3 through 7 until all you have created and named a new
Display Setup for each display you plan to use with your home theater
system.
For now, this is all you need to configure for each Display Setup. If
desired, refer to the next section, “Display Setup”, for explanations of the
other Display Setup options.

Output Path
The Output Path identifies which high-definition video output connector
on the rear panel carries the active video output signal for the selected
Display Setup. Three options are available -– HDMI 1, HDMI 2, and
Component. The output connectors can be assigned to multiple Display
Setups, but only one video output can be active at any given time.
Note
For all source materials with HDCP (High-Bandwidth Digital Content
Protection), video is disabled on the component output. However, the Nº502
menus are still displayed. The Detailed Status Panel identifies the presence of
HDCP source material.
Display Format
The Display Format parameter sets the aspect ratio of the output video
signal. The aspect ratio is a width-to-height definition of the video display
area. The Nº502 has two options:
•
16:9 aspect ratio - standard for HDTV format, this aspect ratio is also
referred to as widescreen. Almost twice as wide as it is high, it closely
matches the aspect ratio of theatrical movie theaters. This setting
should be used for displays with 16:9 aspect ratio.
Nº502 Media Console
Customizing the Nº502
•
4:3 aspect ratio - most commonly used for SDTV format, this aspect
ratio is almost square and is also referred to as full-frame or full-screen.
This setting should be used for displays with 4:3 aspect ratio.
When the source video and the display have different aspect ratios,
letterboxing or pillarboxing is implemented.
•
Letterboxing refers to the black bars placed above and below the
picture to fill up the screen when the source material is in a
widescreen format and the display is set to a full-frame format.
•
Pillarboxing refers to the black bars placed to the right and left of the
picture to fill up the screen when the source is in a full-frame format
and the display is in a widescreen format.
Optionally, use the Zoom Ratio parameter to reduce or eliminate any
black bars introduced by the aspect ratio of the source material.
Note
Color Space
For information regarding how the video setup, DVD setup, and display
settings interact to affect the display output, refer to the “Troubleshooting
Display Formats” section of the Chapter 4: Troubleshooting & Maintenance.
The Color Space parameter identifies the color mapping format used for
the video output signal. Color space is a mathematical model that uses
numerical combinations of red, green, and blue to map the colors of the
video image. The available selections are:
•
YCbCr 4:4:4 – provides a higher-resolution video output for those
higher sample rate formats available in some digitally formatted video
source materials .
•
YCbCr 4:2:2 – standard compressed format common to DVDs and
digitally formatted video source materials.
•
RGB Normal – provides a standard RGB color conversion to the
source video. This format is only available for HDMI outputs.
Typically, this setting is used with home theater displays, such as
plasma and front projections.
•
RGB Expand – utilizes an expanded RGB color space definition to
provide higher color resolution. This format is only available for
HDMI outputs. Typically, this setting is used with PC-type displays,
such as DVI interfaces.
For optimal results, we recommend setting the Color Space
parameter to the format that matches the native format of the
video display. The color space conversion of the input source material is
then done by the Nº502, using its state-of-the-art video processing
technology, rather than by the video display, which may not have the
same processing capabilities. If necessary, refer to the documentation
included with the display to determine its native color space format.
3-5
Customizing the Nº502
Resolution
Mark Levinson
The Resolution parameter identifies the video resolution, either interlaced
or progressive, of the output signal. Interlaced video reduces bandwidth
by loading only half of the frame at a time; first the even lines, then the
odd lines. Progressive video loads the whole frame in sequence, providing
better picture quality but also increased bandwidth usage as the frame rate
is doubled.
The available Resolution selections are:
•
Standard Definition – uses interlaced video at 480i or 576i.
•
Enhanced Definition – uses progressive video at 480p or 576p
resolution.
•
High Definition 720p – uses progressive video at 720p resolution.
•
High Definition 1080i – uses interlaced video at 1080i resolution.
•
High Definition 1080p – uses progressive video at 1080p
resolution. If the Component Video Output is selected, then this
option is not available for selection.
For optimal results, we recommend setting the Resolution
parameter to the format that matches the native format of the
video display. The resolution conversion of the input source material is
then performed by the Nº502, using its state-of-the-art video processing
technology, rather than by the video display, which may not have the
same processing capabilities. If necessary, refer to the documentation
included with the display to determine its native resolution.
3-6
Note
Resolution is a preference setting – if the preferred selection is not available,
then the Nº502 selects a different resolution level. For example, if the
Resolution is set to 1080p but the output is set to Component Video, the
Nº502 outputs at a 1080i resolution level. The display EDID can also affect the
allowed Resolution settings.
Output Frame
Rate
Selects the frame rate of the output signal. The Output Frame Rate
identifies the number of frames transmitted per second. Available
selections are 50Hz or 60Hz. For 1080p resolution, 24Hz is also available.
Zoom Ratio
The Zoom Ratio parameter is used to fill the display area, reducing or
eliminating the black bars resulting from letterboxing or pillarboxing.
Before adjusting the Zoom Ratio parameter, ensure that the Nº502 has
been properly configured to match the aspect ratio of the associated
display by verifying that the Display Format parameter is set to the proper
aspect ratio.
Available selections include:
•
Normal – select when no zoom is desired.
•
Widescreen – select when using a 16:9 display and the source
material is widescreen anamorphic with a 2:35:1 aspect ratio.
Nº502 Media Console
Customizing the Nº502
•
Fill – select when viewing content of a full-frame (4:3) source on a
16:9 display or when viewing the content of a letterbox (widescreen)
source on a 4:3 display. In the second case, if the source material is an
aspect ratio other than 16:9, the letterboxing may not be totally
removed.
•
Fill + Widescreen – select for the maximum amount of zoom. This
is equivalent to having both Fill and Widescreen zoom modes active
at the same time. Picture content may be cropped on the top, bottom,
and sides.
The Zoom Ratio parameter removes or reduces the black bars from
letterboxing or pillarboxing by zooming into the picture. This results in
the slight cropping of image edges and a small amount of resolution loss
due to image scaling, but no geometric distortions are added to the source
materials.
SD Component
Black Level
Note
The SD (Standard Definition) Component Black Level parameter sets the
black level of the video output. The black level is the adjustment required
to reach a pure black, or true black, image display. Video displays are
calibrated so that the black of the image display is true to the black information of the video signal. Available selections are 0 IRE and 7.5 IRE.
Select the setting that best matches the capabilities of the display.
This parameter is only available in 480i format on the component video
output.
Setup Step 2: Speakers
The second decision you need to make is how many speakers your
home theater system must support. Specifically, what is the maximum
number of speakers and subwoofers that you plan to use?
Add a new Speaker Setup for the maximum number of
speakers, including subwoofers, that you plan to use in your
home theater system and name it “Master”. Or select the preset that most
closely matches your maximum speaker configuration and modify it.
Calibrate the Master Speaker Setup, using the Automatic Calibration
process described in the next section, “Speaker Setup”. This provides you
with a maximum-speaker system that is fully calibrated for speaker
distances, output levels, and Room Correction.
There is a specific purpose to creating this master speaker configuration,
and it’s an important feature of the Nº502 Media Console.
The main advantage of this master speaker configuration, coupled with
the Add New functionality, is it dramatically reduces the amount of time
needed to setup and calibrate the speakers of your home theater system.
3-7
Customizing the Nº502
Mark Levinson
Whenever a speaker is added to the system, the Nº502 needs to be recalibrated. So, if you started your setup with a 2-channel Speaker Setup, when
you added the surround speakers, you’d have to recalibrate the whole
system. However, when a speaker is deleted, you don’t need to recalibrate
the system because all of the calibration settings for the other speakers
remain the same.
Therefore, you could create up to 10 Speaker Setups while only
having to calibrate ONE of them.
For example, if your maximum speaker configuration is a 7.2-channel
system:
1. Create a Master Speaker Setup containing a 7.2-speaker system (Front
L/R, Center, Surround L/R, Surround Back L/R, and Subwoofer 1 L/R).
2. Calibrate the Master Speaker Setup.
3. Create copies of the Master Speaker Setup by using the Add New
option.
4. Modify the new Speaker Setups for different speaker configurations.
In this manner, you can make multiple speaker configurations – for
example, 2-channel, 5.1-channel, 2-channel plus subs, etc .– while
calibrating only the Master Speaker Setup, because in every other
configuration you are only deleting speakers.

To set all of the speakers to full range, select the Set All Full Range
parameter. This parameter sets the Front L/R, Center, Surround, and Back
speakers to Full Range. If this option is selected, the Nº502:
Caution!
•
Does NOT set the Subwoofer 1 or Subwoofer 2 outputs to Full Range.
•
Does NOT route any low-frequency information, other than the LFE
channel information, to the subwoofer outputs.
In extreme cases, center and surround speakers may be damaged if
sent lower frequency information than they are specified to handle.
Subwoofer LPF
Identifies the crossover point of the subwoofers. This setting affects both
Subwoofer 1 and Subwoofer 2.
The Subwoofer LPF parameter can be configured in two ways:
•
Complementary – the Subwoofer LPF is automatically set to the
lowest crossover frequency of the active speakers, as determined by
the Frequency crossover settings. With this setting, the output of the
subwoofer(s) is designed to complement that of all other channels
perfectly to ensure that all of the source information is reproduced.
•
Full Range – no crossovers are enabled. This setting is provided for
subwoofers with internal crossovers that cannot be bypassed.
Subwoofer Slope
Sets the slope of the subwoofer low-pass filter. The available options are
24dB per octave or 48dB per octave.
Speaker
Calibration
The Nº502 offers both automatic and manual calibration of speaker
distances and output levels for each Speaker Setup. Calibration helps to
ensure accurate output-signal arrival time and level at the primary
listening position. However, calibration is not a substitute for proper
speaker placement.
All calibration settings are saved with each individual Speaker Setup.
Automatic calibration requires the HSG microphone kit. To order a HSG
microphone kit, refer to Chapter 1: Getting Started for details.
The Automatic Calibration procedure optimizes the Nº502 audio outputs
and performs Room Correction. The procedure calibrates for:
•
Room Correction
•
Speaker Distances
•
Speaker Levels

For optimal results, read all instructions before performing the Automatic
Calibration procedure.
The Room Correction adjustment, which is part of the Automatic
Calibration procedure, uses four microphones to measure the acoustic
characteristics and modal properties of the listening room and then
applies specific parametric filters to the outputs. The main advantages of
the Room Correction adjustment are:
•
it addresses what is important for the audio – the objective is not to
make the numbers better, but to make the audio sound better.
•
resonances are a feature of the room – treating them helps the entire
room, and improves the bass uniformity of the room.
•
the amount of correction can be adjusted by the listener.
•
the calibration is simple and reliable – it can even screen out external
noise sources.
For more information about the Room Correction adjustment and why
it’s an important part of enabling the system to run at optimal
performance levels, refer to the “Understanding Room Correction”
section in the Appendix.
Room Correction is not available with manual calibration.

Setup:7.2:AutoCalibration
Check Microphones
Run Automatic Calibration
Note
Follow the steps below to perform the Automatic Calibration procedure.
The calibration is done in two steps: Check Microphones and Run
Calibration. Until the Check Microphones test is performed successfully,
the Run Calibration menu option is grayed out and not available. This
prevents calibration errors due to potential microphone problems and
verifies that the Nº502 can accurately detect all of the microphones before
beginning the calibration.
The HSG microphone kit is required for the Automatic Calibration procedure.
Do not use other microphone brands.
Be sure to read and observe the care and handling instructions included
with the microphone kit to ensure optimal microphone performance.
Caution!
The microphones and cables included in the HSG microphone kit are
delicate and require careful handling. Dropping or otherwise physically
abusing the microphones may cause errors during use or irreparable
damage to the microphones. Treat the microphone cables carefully; do
Nº502 Media Console
Customizing the Nº502
not sharply bend the wires or place objects on them. Finally, never
make or break the microphone input connections unless the No502 is
placed in Standby mode or powered off.
To Perform Automatic Calibration:
1. Put the Nº502 into Standby mode.
2. Connect the Mark Levinson microphone cables to the Nº502 rear
panel Microphone Input connectors. Ensure there is a good
connection between the microphone cables and the connectors.
We recommend labeling each microphone with the microphone
input number reflected on the Nº502 rear panel connector, to make
possible troubleshooting simpler.
3. Take the Nº502 out of Standby mode.
4. Press Setup.
5. Select Automatic Calibration from the Speaker Setup menu and press
Enter.
Check Microphone
Test
6. Select Check Microphones and press Enter.
The Check Microphones procedure:
•
confirms that the microphones are properly connected and
functioning.
•
calculates the average level of the microphones connected to the
Microphone Input connectors to ensure that the microphone
levels are consistent. This average-level calculation eliminates
errors due to different individual microphone levels by allowing
the Nº502 to compensate for individual microphone sensitivities.
7. Place the four microphones in the listening space as instructed on the
display. Both initial instructions and status information are displayed
as the test proceeds.
Proper microphone placement is essential to achieving optimum
calibration results. Pay particular attention to ensuring that the
microphones are properly placed.
During the Check Microphones test, position the microphones:
D as close together as possible.
D relatively centered between, and equidistant from, the front left
and front right speakers.
D in a clear line-of-sight path with all of the speakers.
D in a location unobstructed by furniture and other fixtures, where
echoes will not obscure calibration noise signals.

Delete Video Profile
Video Profiles provide the video processing and video output controls for
the Nº502 Media Console. The parameters include basic controls such as
brightness or contrast, and state-of-the-art video processing technology
that can enhance the video source material. Because of the Activity-based
nature of the Video Profiles, you can create individual Video Profiles for
each video input source or type, allowing you to tailor your viewing
preferences to the media you’re watching and minimize the time you
spend adjusting the system.
The Video Profile Setup menu contains the following options:
•
Name – customizes the name of each Video Profile. Refer to the “Add
New, Name, & Delete” section found earlier in this chapter for more
details.
•
Deinterlacing – identifies the conversion type applied to the
interlaced video.
•
Adaptive Threshold – adjusts the adaptive processing, depending
upon the video source material.
•
Film Detection – detects the presence of film-originated material.
•
Chroma Bug Correction – corrects the chroma bug caused by
some mpeg decoding devices.
•
Noise Reduction – adjusts how much noise is filtered out.
•
Brightness – adjusts the brightness or overall tone of the video.
•
Contrast – adjusts the contrast, or the variations between the
lightest and darkest areas of the video image.
•
Saturation – controls the saturation, or color intensity, of the video
image.
•
Tint – controls the color balance of the video image.
•
Sharpness – enhances the sharpness of the video image.
•
Delete Video Profile – deletes Video Profiles that are no longer
needed. Refer to the “Add New, Name, & Delete” section found earlier
in this chapter for more details.
In most cases, there is no need to change the Video Profile parameters
from the default settings as these values are designed to be optimal with
most properly adjusted video source materials. However, the Video
Profiles are exceptionally useful when source-specific adjustments are
needed, removing the need to constantly alter the global settings of the
video display.
For instance, if you find that classic movies always seem to look washed
out, you could make a “Classic Movie” Video Profile that modifies the
Contrast and Brightness settings to improve the image. This Video Profile
can then be loaded whenever you want to watch an old movie and the
adjustment will be made automatically.

Customizing the Nº502
Deinterlacing
Mark Levinson
Deinterlacing is the process of converting the fields of an interlaced video
signal into a progressive frame. This process may introduce some image
degradation as it combines two fields. For example, since moving objects
are in a different position in each field, when the frames are put together
the moving objects don’t match up exactly, which creates a combing
effect (jagged edges that don’t line up correctly). Image flickering can also
be an issue, as well as various other video artifacts. However, the advanced
processing of the Nº502 can mitigate some of these artifacts.
The Nº502 has three types of deinterlacing formats available for selection:
Temporal Filtering -– applies a time-based filter between two or more
adjacent fields. The filter softens the image to help smooth motion
artifacts. This method is a linear deinterlacing technique.
Field Merging – combines adjacent fields using a weave-type algorithm.
This method is a linear deinterlacing technique.
Adaptive – selects the deinterlacing method based on the motion of
particular areas of the video frame. Still areas are processed differently
than areas with fast motion to provide the best overall image. This
method is a non-linear deinterlacing technique. This mode should always
be used, unless there is a specific artifact to address.
3-26
Adaptive
Threshold
Adjusts the adaptive processing applied to the video output signal. When
the parameter is selected, an adjustment bar opens with a range of 0 to 15.
The smaller numbers are better for fast moving scenes; the larger numbers
are better suited for highly detailed static scenes. This parameter is only
available if the Deinterlacing parameter has Adaptive selected.
Film Detection
Detects the presence of film-originated material so that the original
film-frame sequence may be recovered by weaving together the
appropriate video fields. This option can be turned On or Off; there are no
additional settings.
Note
This parameter is most effective when the video input has not been previously
scaled or processed by the source device and is a 480i or 576i interlaced
format.
Chroma Bug
Correction
Note
Corrects the chroma bug caused by some mpeg decoding devices. This
parameter can be turned On or Off; there are no additional settings.
This parameter is only effective when the video input is an interlaced format –
480i, 576i, or 1080i.
Nº502 Media Console
Customizing the Nº502
Noise Reduction
The Noise Reduction parameter reduces the video noise often present in
analog input sources. Selecting this option opens an adjustment bar with
a range from 0 to 64 in increments of one. The larger the number selected,
the greater the suppression of the noise.
Brightness
The Brightness parameter controls the lightness or overall tone of the
image, just like the Brightness control found on a television or computer
monitor. Technically, it controls the level at which black is reproduced on
the display.
When the Brightness parameter is selected, an adjustment bar displays.
The range of the Brightness adjustment bar is –64 to +64 in increments of
one.
Note
Trying to make the picture “blacker than black” by turning this control down
too far reduces the visible detail during the dark scenes of the video.
Contrast
The Contrast parameter controls the variations between the lightest and
darkest areas in the image. Technically, it controls the level at which the
peak white is reproduced, up to the maximum light output capability of
the display.
Note
Trying to exceed this maximum light output level reduces visible detail during
bright scenes of the video. In extreme cases, trying to exceed this maximum
can actually damage the video display.
When the Contrast parameter is selected, an adjustment bar displays. The
range of the Contrast adjustment bar is –64 to +64 in increments of one.
Saturation
The Saturation parameter controls the color intensity, or vividness, of the
image. Visually, it controls the “saturation” of the color in the video
signal. Technically, it controls the strength of the color portion of the
video signal compared to the black-and-white portion of the signal.
When the Saturation parameter is selected, an adjustment bar displays.
The range of the Saturation adjustment bar is –64 to +64 in increments of
one.
Tint
The Tint parameter controls the color balance of the image. Visually, the
Tint parameter controls the “hue” or “color balance” of the video signal.
Technically, it controls the phase of the color portion of the video signal.
When the Tint parameter is selected, an adjustment bar displays. The
range of the Tint adjustment bar is –64 to +64 in increments of one.
3-27
Customizing the Nº502
Mark Levinson
Sharpness
The Sharpness parameter controls the amount of “sharpness
enhancement” that is applied to the incoming video signal. The setting
acts on the vertical and horizontal, as well as luminance and chrominance parameters to offer an enhanced depth in the picture as well as
greater small-object detail. In general, the lower settings are applicable for
digital displays and sources, while the higher settings may be preferred for
CRT-based displays and analog sources.
Note
Indiscriminate use of the Sharpness parameter distorts the picture by adding
unnecessary ringing and noise to the video image. If adjustment is required,
turn up the Sharpness control until a slight “halo” forms around the transitions from light to dark or dark to light. Then back off the adjustment until the
“halo” disappears.
When the Sharpness parameter is selected, an adjustment bar displays.
The range of the Sharpness adjustment bar is 0 to +64 in increments of
one.
Audio Profiles
Audio Profiles provide the audio processing and audio output controls for
the Nº502 Media Console. Because of the Activity-based nature of the
Audio Profiles, you can create individual Audio Profiles for each input
source or type, allowing you to tailor your listening preferences while
minimizing the time you spend adjusting the system.
3-28
In most cases, there is no need to change the Audio Profile parameters
from the default settings as these values are designed to be optimal with
calibrated speakers.

The Mono Signal, 2-Channel Signal, and Multi-channel Signal menu
options all relate to the selection of the default surround modes. The
default surround mode is assigned to any incoming input source that
matches the requirements for the surround mode defined.
•
Select the Mono Signal surround mode that you want assigned to any
incoming mono input sources for the active Audio Profile.
•
Select the 2-Channel Signal surround mode that you want assigned to
any incoming 2-channel input sources for the active Audio Profile.
•
Select the Multi-Channel Signal surround mode that you want
assigned to any incoming multi-channel input sources for the active
Audio Profile.
The surround mode can always be changed from the Profile setting by
using the Surround Mode Adjust button on the front panel or the
Surround button on the remote control. However, these changes are
temporary. If the Activity is changed or the incoming source is
interrupted, the surround mode reverts to the saved Audio Profile setting.
Some of the surround modes are dynamic and depend upon the Speaker
Setup and the incoming input source. Not all surround modes are
available in all situations. Refer to the “Using Surround Modes” section
found later in this chapter for more details.
LFE Mix
The LFE Mix parameter controls the output level of the LFE (Low
Frequency Effects) information – the .1-channel information – that is sent
to the audio output(s) labeled Subwoofer. Low frequencies from up to
seven other channels may be combined with the LFE information to
create the subwoofer output signal, which significantly increases
subwoofer output levels.
Careful adjustment of this parameter provides proper tonal balance and
reduces the risk of subwoofer overload. When the speaker setup does not
include a subwoofer, the LFE information is mixed into the speakers that
are set to Full or that have the lowest crossover points.
Selecting the LFE Mix parameter opens an adjustment bar with an
adjustment range of –10 to 0dB in 1dB increments.
L7 Auto Azimuth
The L7 (Logic 7) Auto Azimuth parameter maximizes steering accuracy.
When set to On, the Nº502 continually monitors the 2-channel input
signal and automatically adjusts the relative level and time offset of the
input channels to ensure that signals are sent to the appropriate channels
3-29

with maximum separation. When set to Off, the accuracy of the selected
surround mode varies among sources.
We recommend setting this parameter to On for film and broadcast
sources, and to Off for music sources. The L7 Auto Azimuth parameter
only applies when the Logic 7 surround modes are active.
Surround Back
Processing
The Surround Back Processing parameter determines the type of decoding
used for the surround processing of the audio signal. Two options are
available - Dolby Digital EX decoding or DTS-ES decoding. Each option
can be turned to Off, On, or Auto.
Dolby Digital Decoding
Dolby Digital Surround EX decoding is available when both the Surround
and Surround Back speakers are present and Dolby Digital Surround EX
decoding is active. Matrix decoding is then applied to derive the Surround
Back channels.
When the Surround Back Processing>Dolby Digital EX parameter is set to:
3-30
•
Off – Dolby Digital Surround EX decoding is NOT activated,
regardless of the input source.
•
On – Dolby Digital Surround EX decoding is always activated.
•
Auto – Dolby Digital Surround EX decoding is activated for flagged
5.1-channel Dolby Digital Surround EX sources. If the incoming
source is NOT flagged, then the decoding remains Off.

connector(s) to be used for the current Activity. Selecting the Video In
menu option displays the list of video input connectors available on the
rear panel. Select one of the available connectors to associate it with this
Activity.
Input Aspect Ratio
The Input Aspect Ratio parameter identifies the aspect ratio of the input
signal. This parameter, combined with the Display Setup: Display Format
parameter, ensures that all video sources are appropriately scaled. There
are three available settings:
•
Auto - sets analog and DVI source material to a 16:9 aspect ratio.
HDMI input sources specify the aspect ratio of the source material.
•
16:9 - treats all incoming source material as 16:9, regardless of the
existing format.
•
4:3 - treats all incoming source material as 4:3, regardless of the
existing format.
This control is used to aid the Nº502 in identifying the input aspect ratio
for correct processing. Generally, it should be set to Auto. But if a source is
not correctly identified, this control can be used to override the default
processing.

Stereo Analog In
Level
3-34
The Stereo Analog In(put) Level parameter adjusts the 2-channel stereo
analog audio input levels. Since analog audio sources can have a wide
range of input levels, the Nº502 allows the input levels to be
independently adjusted for each Activity through the Analog In Level
parameter.
Selecting the Stereo Analog In Level parameter opens an adjustment bar,
with an available range of –18.0dB to +12.0dB in 0.5dB increments.
Main Audio Delay
The Main Audio Delay parameter delays the audio signal until the sound
and picture are synchronized. This parameter should only need
adjustment if the audio and video become out of sync. This can happen if
the system uses any kind of post-processing on the video source, which
tends to add a small delay to the video output. Adjusting the Main Audio
Delay parameter on the Nº502 delays the audio signal to compensate for
any inherited video output delay, for each individual Activity.
Selecting this parameter opens an adjustment bar, with a range of 0.0ms
to 500.0ms in 0.5ms increments.
HDMI Audio
Output Options
This parameter identifies the format of the HDMI audio output signal.
The available selections include:
•
Encoded – the native format of the incoming signal is output. If the
receiving device does not recognize the native format, the Nº502
prompts a change to the audio output format.
•
PCM – the incoming signal is converted to a downmixed PCM format
before it is output.
•
Off – turns off the audio output entirely. If Off is selected, then NO
audio is output from the HDMI rear panel output connectors.

The Restore Options menu provides access to the Restore Factory Settings
parameter, which restores all parameter settings to the factory defaults.
Restoring the factory settings of the Nº502 erases all currently customized
settings, calibration values, and setup parameters. Once the factory
settings have been restored, all other values are permanently deleted.
Before performing this function, make sure that you’ve saved the Nº502
configuration settings. We’ve provided a configuration tool to make this
easier to accomplish. The Nº502 can download your configuration
settings to a file on the hard drive of a computer, via the Ethernet port on
the rear panel of the Nº502. For more information regarding how to save
your configuration, refer to the “Restoring Factory Default Settings”
section of Chapter 4: Troubleshooting and Maintenance.
When Restore Options is selected, a warning message is displayed. If
you’re sure you want to restore the factory defaults, select Restore and
press the Enter button. Otherwise, select Cancel and press the Enter
button to exit out of the menu without restoring the factory defaults.
Note
All parameter default settings are identified in the Menu Trees, which can be

Triggers
The Nº502 provides four trigger outputs that can be used to control other
products, such as amplifiers, lights, shades, and video screens. The triggers
3-41
Customizing the Nº502
Mark Levinson
can be activated by selecting a specific Activity or by taking the Nº502 out
of Standby mode.
For example, you might have an Activity Setup called “Movie”. When the
Movie Activity is selected, Trigger 1 activates to lower the video screen for
your front projection system, while Trigger 2 activates to close the
window shades. This example has Trigger 1 and Trigger 2 activated by an
Activity.
If Trigger 3 is set to activate when the Nº502 is taken out of Standby
mode, it might send a signal to the amplifiers so that they are powered up
at the same time.
Trigger Activation
The first decision you need to make is how you want the trigger outputs
activated – by the selection of an Activity or by leaving the Standby mode.
To set the activation method, enter the Setup>User Options>Control
Options menu. This menu has four available selections, Trigger 1 to
Trigger 4, allowing you to set the trigger activation methods individually.
Select the trigger location that you want to set up, and then select the
activation method:
•
Out of Standby – activates the trigger when the Nº502 is removed
from Standby mode.
•
On Demand Only – activates the trigger only when a specific
Activity is selected.
3-42
When activated, the trigger supplies a 12V signal to the associated rear
panel Trigger connector.
On Demand Only
Setup
When the On Demand Only option is selected, you must then configure
the specific Activity that turns on the trigger.
To associate the Activity to an On Demand Only trigger, go to the
Setup>Activities menu. Select the Activity that you want the trigger
activation associated with and then select the Triggers option.
The triggers can be set to two different states for each specific Activity:
Note
•
Trigger On – selecting the Activity supplies a 12V signal to the
associated rear panel Trigger connector.
•
Trigger Off – the Trigger supplies no voltage to the associated rear
panel Trigger connector when the Activity is selected.
Any of the Trigger Outputs can also be assigned to a Function key on the
remote control. In this case, the Trigger Output is activated whenever the
Function key is pressed.
Nº502 Media Console

Internal Web Pages
The Nº502 supports network connection to a computer through the
Ethernet port. The Internal Web Pages act as the Nº502’s interface with
the network. These pages provide:
Note
•
Download/Upload Configuration - the Nº502 configuration and
calibration settings can be downloaded to a computer via the rear
panel Ethernet port. Previously saved configurations can also be
uploaded in the same manner. For more information, refer to the
“Saving the Nº502 Configuration” section of the Appendix.
•
Software Upgrade - the interface for upgrading the Nº502
operating software. This interface will be used for any future software
upgrades. A separate document with further explanation will be
available with future software upgrades.
•
Error Reporting - the Error Log page tracks ML Net or
system-related error messages. This page is a diagnostics tool for Mark
Levinson Customer Service use.
To access the Internal Web Pages requires proper network setup on both the
Nº502 and the computer. To set up the computer, refer to your computer
operating manual. To set up the Nº502, refer to the “Network Setup”
description in the “Control Options” section found earlier in this chapter.
ML Net
The ML Net protocol allows you to control two or more Mark Levinson
products simultaneously via the Ethernet port.
To use ML Net, the following conditions are required:
•
only compatible with Mark Levinson products.
•
all products must have Ethernet communication ports.
•
an IP router with Auto-detect, capable of 10baseT or 100baseT
operation.
Refer to the product documentation of each Mark Levinson product to
verify compatibility.
Note
Since ML Net operates through the use of a router and the Ethernet
connection, all devices must have networking capability. To set up the Nº502
for network operation, refer to the “Network Setup” description in the
“Control Options” section found earlier in this chapter.
3-43
Customizing the Nº502
Masters and Slaves
Mark Levinson
ML Net uses a single “Master” device to control specific functions of other
ML Net-capable Mark Levinson products. An ML Net system can only
have one “Master” device; all other devices in the system become
“Slaves”. Slave devices receive and respond to the commands of the
Master device.
An ML Net system can simultaneously support one Master device and up
to 16 Slave devices. In most cases, the Master device is the Nº502 Media
Console. The Nº502 can never be a Slave device.
Note
If assigning a 17th Slave device is attempted, the ML Net Setup and ML Net
Status menus indicate that the designated Slave device remains in an
Unassigned state.
The Master device performs the following ML Net functions:
3-44
Note
Connecting the
Devices
•
Status Reporting – status conditions of the assigned Slave devices
can be reported to the Master device; the status includes Temperature,
Session Time, Total On Time, and Fault Reporting.
•
Display Intensity – the Display Intensity level of the front panel
display and LEDs on the Master device is replicated on all assigned
Slave devices.
The Display Intensity master command does NOT change the brightness
intensity of the amplifier LEDs.
•
Standby State – the Standby state of the Master device is replicated
by all Slave devices. When the Master device is put into Standby
mode, all assigned Slave devices go to Standby mode. When the
Master device is taken out of Standby mode, the Slave devices should
also come out of Standby mode.
•
Synchronized LEDs – the Standby LEDS of the Master device and
all assigned Slave devices blink in unison.
The first step is to connect all of the devices together. Ensure that all
components are powered Off or in Standby mode before connecting to the
Ethernet ports.
To set up an ML Net system:
•
All devices must be connected to an Auto-Detect capable router using
straight-through Cat. 5 cables.
•
Each device must be connected to the same subnet, which must
include a DHCP server. In most cases, this functionality is part of the
router.
•
Each device must have a unique IP address (usually assigned via DHCP
server).
Nº502 Media Console
Customizing the Nº502
The figure below illustrates a typical ML Net setup:
If more devices are desired than the router can handle, connect the
additional devices first to a switch, then connect the uplink of the switch
to a normal port on the router.
Once connected, power on the devices one at a time to ensure proper
functioning of the ML Net controls. The Nº502 Media Console must be
powered on first. Allow each device to complete the initialization
sequence before proceeding to the next device.
Note
Discovering Slaves
-ControlOptions-MLNet
ML Net Setup
ML Net Status
If a Trigger control and ML Net are both active on the same device, the
Trigger control takes priority.
Before the Master device can control any Slave device, the Slave devices
must be “discovered” and assigned to the Master device.
The Nº502, as the Master device, searches for other devices via the
Ethernet connection, compiling a list of discovered devices and their
current status. Each discovered device must then be assigned to the ML
Net system.
To assign the Slave devices to the Nº502, go to the ML Net Setup menu,
located in the Setup: Control Options menu.
All of the devices found by the Nº502 are listed in the ML Net Setup
menu. The discovered devices are described by the following states:
•
Unassigned – discovered device that is not assigned to the Nº502 or
any other Master device.
•
Assigned – discovered device that is assigned (by the user) to the
Nº502.
3-45
Customizing the Nº502
Mark Levinson
•
Other – discovered device is assigned to a different Master device.
•
Inactive – previously discovered device was assigned to the Nº502
but is no longer visible due to a lost connection.
Each listed device can be assigned or unassigned to the ML Net system. If
you choose to unassign an already assigned device, a warning message is
displayed asking for confirmation before unassigning it.
Note
In some cases, it may take a minute or two before changes occur in the ML
Net Setup and ML Net Status device information listings. This delay is due to
the nature of the Ethernet connection, as device status information may not
be immediately noted by the router.
Slaves can only be assigned to a Master from within the menu system of
the Master. You cannot assign Slaves to a different Master than the one
you are accessing.
ML Net and Link2
A system can use ML Net and Link2 together, but the Link2 control takes
precedence. In this case, the ML Net Slaves enter a Status-Only mode
whenever the Slave is under Link2 control. The Status-Only mode allows
the notifications and status requests, but any attempt made by the Master
to change the state of the ML Net Slave is ignored. The Slave sends a
message to the Master indicating it’s in Status-Only mode.
Status Reporting
The ML Net system provides Slave status information on the Master
device. These status reports are information-only and can be accessed on
the Nº502 in the ML Net Status menu. Select any assigned Slave device
from the menu list and the following status information is displayed:
3-46
•
Temp (Temperature) – identifies the current operating temperature
of the Slave device. The status field can include up to eight
temperature values, depending upon the capabilities of the Slave
device.
•
Session Time – identifies the amount of time that the Slave device
has been powered On. This time resets each time the Slave is put into
Standby mode.
•
Total On Time – identifies the total amount of time that the Slave
device has been powered On since its manufacture. Putting the Slave
into Standby mode does NOT reset this time.
If a Slave device is Inactive or Unassigned, then the status information is
not available. A Slave device is assigned to a different Master; the status
information is also not available.
Note
If the Nº502 cannot find any Slave devices, the message “No Devices Found”
is displayed on the ML Net menu pages.
Nº502 Media Console
Fault Reporting
Customizing the Nº502
The Nº502, as the Master device, is capable of reporting selected error
conditions of the Slave devices. Error messages are posted on the front
panel and main displays when the failure event occurs in the Slave device.
The error message identifies the failure and the identity of the Slave
device experiencing the failure.
The error conditions of the Slave devices that the Nº502 can report are:
•
Slave Device DC Offset – indicates that the Slave device is experiencing a signal-related fault.
•
Slave Device Over Current – indicates that the Slave device is
experiencing an over-current condition.
•
Slave Device Over Temperature – indicates that the Slave device
is overheating.
•
Signal – indicates that the Slave has had a general signal fault.
•
Power – indicates that the Slave has had a power failure.
•
Unknown – indicates that the Slave has a fault condition that is not
supported by the current ML Net version.
Using Surround Modes
The Nº502 Media Console logically presents the available list of surround
modes based upon the detected input and the system setup. This process
simplifies surround mode selection by presenting only the relevant modes
for each Activity. The available surround modes are then assignable to any
relevant Activity.
Selecting A New

The surround mode for the current Activity can be changed via the
Surround button.
1. Press the Surround button to display the list of surround modes. This
list is dynamically built by the Nº502 and includes all of the modes
available for the current Activity, based on the Activity setup and the
incoming source.
2. Use the and buttons to scroll through the list. The current mode
is displayed in red text. Repeated presses of the Surround button also
scrolls through the list.
3. Press the Enter button or the button to select the desired surround
mode. The selected surround mode now displays in red text,
indicating that it is now the active mode.
4. To close the list, press either the button or the Menu button.
The current Activity now has a new surround mode. However, this is a
temporary change and may be lost when a new Activity is selected or if
the input source is interrupted.

are indicated as such in the description.
For explanations of the individual Surround mode parameters, refer to the
“Surround Mode Parameter Descriptions” section found later in this
chapter.
Logic 7
3-48
The Logic 7 mode is an advanced mode that extracts the maximum sound
information from either surround-encoded programs or conventional
stereo material. These surround modes can derive up to 7.1-channels of
surround sound from a 2-channel or 5-channel input source. The Logic 7
mode provides full-frequency stereo surround channels that realistically
increase the perceived width, length, and sense of envelopment of the
listening space.
The Logic 7 mode also has additional bass-enhancement capability that
circulates low frequencies in the 40Hz to 120Hz range to the front and
surround speakers. This creates a soundstage that is broader and wider
than when the subwoofers are the sole source of bass energy. This
additional bass enhancement feature can be turned On or Off.
L7 Film (Logic 7 Film)
This Surround mode is designed for enhanced playback of 2-channel
stereo, multi-channel, or matrix-encoded film sources. Use this mode
with any source that contains Dolby Surround, DTS:Neo6, or similar
matrix-encoding to experience increased center channel intelligibility
and more accurate placement of sounds.

playback of recordings that contain added reverb. The L7 Music Surround
mode enhances the listening experience by extracting ambient sounds
from the input source and sending these sounds to all speakers. Since the
ambient sounds are heard from all directions, it creates a realistic playback
presentation that simulates what listeners experience in real spaces.
We recommend using this mode for classical music scores, since classical
music presentations are typically recorded in real spaces with additional
reverb to enhance the stereo mix.

Mode parameters.
5-Speaker
Enhance
Academy Filter
The 5-Speaker Enhance parameter simulates 7-channel playback in
5-channel speaker configurations. When set to On, the Nº502 provides an
increased sense of spaciousness and envelopment through the surround
speakers. This enhancement is most noticeable when the surround
speakers are positioned to the sides of the primary listening position, or
when the primary listening position is located against the rear wall. The
effectiveness of this parameter varies within the listening space. For best
results, place the surround speakers to the left and right of the primary
listening position. This parameter is available in all Logic 7 modes.
The Academy Filter parameter restores the proper tonal balance of older
mono film sources that have much narrower frequency responses than
more recent mono film sources. This parameter is available in the Mono
Logic mode.
3-55
Bass Enhance
The Bass Enhance parameter enhances the stereo bass, which results in
low-frequency reproduction that is less localized and more realistic in the
listening space. The effectiveness of this parameter varies depending upon
the room acoustics and the ability of the surround speakers to reproduce
low frequencies. For best results, use front, side, or rear speakers that are
capable of reproducing frequencies of 40Hz or lower. This parameter is
available in all Logic 7 modes.
Center Width
The Center Width parameter adjusts the center image.
•
When set to Min, the center image is heard just from the center
speaker.
•
When set to Max, the center image is heard as a “phantom” center

Troubleshooting & Maintenance
No Power
Incorrect operation is sometimes mistaken for malfunction. If problems
occur, see this section for troubleshooting information. If problems
persist, contact your authorized Mark Levinson dealer.
1. Examine the power cord to ensure that it is connected to both the rear
panel connector of the Nº502 and an electrical outlet.
2. Make sure the Nº502 is powered on with the power button.
3. Make sure the Nº502 is not in Standby mode (the LED should not be
slowly blinking).
4. Examine the electrical circuit breaker to ensure that power is being
supplied to the electrical outlet to which the Nº502 is connected.
Remote Control
Doesn’t Work
1. Eliminate obstructions between the remote control IR transmitter and
the front panel display IR receiver/transmitter. The remote control
must be in line-of-sight with the front panel IR receiver for proper
operation.
2. Replace the remote control batteries. Verify that the remote control
batteries are inserted correctly with the proper polarity.
3. Make sure the IR input connector is not being used.
4. Make sure the front panel display IR receiver/transmitter is not
exposed to strong sunlight, halogen light, or fluorescent light. This
can cause IR reception to become unreliable. If the Nº502 is placed
inside a glass cabinet, tinted glass will reduce the remote control
range.
5. If you have multiple Mark Levinson products, verify that you are
using the proper remote control for the product in question.
No Audio Output
1. Make sure that the source device is powered on, playing audio, and set
to the right output connector.
2. Make sure the master volume is set to an audible level.
3. Make sure that the volume is not muted. The LED beside the front
panel Mute button should not be illuminated.
4. Examine audio cables to ensure a solid connection between the Nº502
and associated components.
4-1
Troubleshooting & Maintenance
Mark Levinson
5. Make sure the Nº502 main output connectors are connected to an
operational power amplifier, and that the associated power amplifier
is connected to operational loudspeakers.
6. Verify that the Activity has the correct input and output rear panel
connections selected, as well as the correct Audio Profile. Refer to
Chapter 3: Customizing the Nº502 for more information.
Audio Has a
Humming Sound
1. If a cable TV connection is present, disconnect the cable from the wall
outlet. If this eliminates the humming sound, a ground loop isolation
device is required. Contact your dealer or cable provider for assistance.
2. Disconnect the components one at a time to isolate the problem.
Once the problem is identified, make sure the associated component
is properly grounded and connected to the same electrical circuit as
the Nº502.
4-2
Subwoofer(s)
Distorts
Frequently
The likely cause for the subwoofer(s) to distort is either an incorrectly set
output level or the subwoofer crossover point is set too low. Refer to the
“Speaker Setup” section of Chapter 3: Customizing the Nº502 for more
information.
Analog Audio
Sounds Distorted
1. Distorted analog audio is most likely caused by the input level of the
source being too high. If the input level is too high, then signal
clipping at the analog-to-digital converter occurs. This problem can
be resolved by adjusting the Stereo Analog In Level parameter. Refer to
the “Activities” section of Chapter 3: Customizing the Nº502 for more
information.
2. If the input source has a gain control for the analog output, verify that
it’s not adjusted too high.
Audio or Video RF
Interference
1. Verify that the Nº502 is not positioned too close to RF-emitting
devices. Move such items one at a time to isolate which device is
causing the problem.
2. Replace unshielded cables with shielded cables wherever possible.
Volume Can’t Be
Set to Maximum
Front Panel
Display Not
Working
The user has the option of manually setting a maximum volume level. If
set, this will prevent the maximum specified volume level of the Nº502
from being reached. Refer to the “User Options” section of Chapter 3:
Customizing the Nº502 for more information.
1. Verify that the front panel display has not been deactivated. Verify
that the Display Intensity parameter in the Setup:User OptionsDisplay Options menu is NOT set to Off.
Nº502 Media Console
Troubleshooting & Maintenance
2. Verify that the Monitor Output is not active. Connect a monitor to
the Monitor Out connector on the rear panel of the Nº502. If the
monitor displays an image matching the Main Zone display image,
then the Monitor Output is active. Refer to the “Rear Panel Overview”
section of Chapter 2: Basic Operation for more information.
No Video Output
1. Make sure that the source device is powered on, playing video, and set
to the right output connector.
2. Examine the video cables to ensure a good connection to the
associated component.
3. Verify that the selected output is not analog with an HDCP (HighBandwidth Digital Content Protection) input source. Source material
that carries HDCP-encoding is only available through the HDMI
output. No video is output on the analog output connectors.
4. Verify that the cable connections between the Nº502 rear panel
connectors and the other components are correct.
5. Verify that the Activity has the correct input and output rear panel
connections selected, as well as the correct Video Profile and Display
Setup. Refer to Chapter 3: Customizing the Nº502 for more information.
Video Format
Problems on
Fullscreen Display
Video format problems while using a fullscreen display (4:3 aspect ratio)
are typically due to incompatible or conflicting settings between the
incoming source, the display setup, and the Nº502 video format settings.
Examples of these errors include:
•
Extra pillarboxing (wider than normal black bars on the left & right
sides) and horizontal stretching, so that people appear tall & thin,
caused by incorrect settings on the source.
•
Black bars on the top & bottom and the left & right sides of the image
due to an incorrect aspect ratio setting on the Nº502 Media Console.
•
Black bars on all sides and vertical squashing, so that people appear
short & fat, caused by incorrect settings on the source.
Refer to the “Troubleshooting Display Formats” section found later in this
chapter for possible solutions to these errors.
Video is Behaving
Oddly With HDMI
Connections
Connecting together all of the components of your home theater system
with HDMI connectors requires every piece of equipment in the signal
chain to communicate its capabilities and requirements with respect to
the video stream and possible HDCP encryption. If any piece is not
communicating properly, then odd results can occur. For example, if the
timing of the communication is off, it might cause incorrect colors to
appear on the screen, or to shift all of the video to the left or toward the
top of the screen. If the video monitor doesn’t communicate properly, it
might load the color spacing incorrectly so that the screen appears to be
all one color, instead of displaying normal color.
4-3
Troubleshooting & Maintenance
Mark Levinson
To correct the problem, the system communication needs to be realigned,
which should clear the error. Some issues are easier to clear than others.
Typically power cycling the Nº502 will clear it, but some issues don’t need
a power cycle. We suggest you try the following:
1. Verify the HDMI cables have a good connection with the rear panel
connectors.
2. Put the Nº502 into Standby mode. Wait 10 seconds. Then take the
Nº502 out of Standby mode.
3. Power cycle the Nº502 by turning off the power switch; wait at least
10 seconds, and then turn the power switch to the On position. Then
take the Nº502 out of Standby mode.
4. With the Nº502 turned off, power cycle all other devices that are
connected to the Nº502, such as DVD and CD players, projectors, and
monitors. When finished turning all other devices back on, restore
power to the Nº502 and take it out of Standby mode.
Link2 Not
Working
1. Verify that the Nº502 and the amplifiers are daisy-chained properly.
Refer to the “Link2” section of the Appendix to verify proper setup.
2. Refer to the product documentation of each amplifier to verify
compatibility and the proper cabling.
4-4
3. Power down all of the devices, then power up the Nº502, followed by
each amplifier. Allow each device to go through its initialization
process before powering up the next device. The Standby LEDs should
now be blinking in unison.
Can’t Assign a
Slave in ML Net
You must assign the slave from the Master. Press the Setup button the
Nº502 and select User Options. Then select Control Options:ML Net:ML
Net Setup. Verify that the Slave you want to Assign is in the device list and
check its current state.
If the current state is assigned, then you must first unassign it from the
ML Net system. Once a Slave is assigned, it will not accept another
assignment until it has first been unassigned. Once the device is
unassigned, you can then reassign it to the desired ML Net system.
For explanations about other current states, refer to the “ML Net” section
of Chapter 3: Customizing the Nº502.
Configuration

Working
If you are having difficulty with the Configuration Download, the issue
may be related to the Network Setup of either the Nº502, the Ethernet
connection, or the setup of the connected computer.
1. Verify that the proxy server in the computer’s network setup is
disabled. An active proxy server can interfere with the configuration
download procedure.
Nº502 Media Console
Troubleshooting & Maintenance
2. If the web browser cannot find the Host Name of the Nº502,
verify the following:
•
Ensure that the local DNS server is properly configured. We
recommend configuring the local DNS Server to “DNS
Forwarding” mode. To configure the DNS Server, refer to the
setup manual of the server.
•

the browser, http://ML502.yourhome.network.com - where
ML502 is the default Host Name for the Nº502 and yourhome
is a subdomain in the local network.
•
Enter the IP Address of the Nº502 into the browser, for
example, http://192.168.50.2 - to find the correct address,
refer to Auto IP Address in the Setup:User Options-Control
Options-Network Setup menu.
3. Verify that the Nº502 and computer are connected properly.
Connecting the Nº502 and computer together without a router
requires a special type of network cable. Refer to the “Saving the
Nº502 Configuration” section of the Appendix for more details.
No Connectivity Via
Ethernet
•
•
If All Else Fails...
Verify that the network cables are properly connected between
the router, switch, or hub and the Nº502. If connecting to a
computer, verify that the computer network cable is in the
correct port.
Verify the age of the router, switch, or hub. If the router, switch,
or hub is more than ten years old, there may be a communication
issue with the Nº502. Power cycle the Nº502 and use a newer
router, switch, or hub between the network and the Nº502.
1. Power cycle the Nº502, waiting at least 10 seconds between
powering the Nº502 off and on.

Troubleshooting & Maintenance
Troubleshooting Display Formats
The video format is directly affected by a number of different
variables, causing a wide range of potential format problems between
the input source and the main display. This guide identifies common
format issues and suggests possible resolutions.
Note
This guide assumes that the system you are troubleshooting uses a
Widescreen display.
There are four main places where the video format is directly
impacted:
•
Input Source – the incoming video format has a fixed aspect
ratio and resolution that may not be suitable to the main display.
•
Media Player – most DVD players provide a few different aspect
ratios and zoom options.
•
Display Screen – most displays have a variety of resolution
settings, although the aspect ratio is typically fixed.
•
Nº502 Media Console – the Nº502 provides different aspect
ratio settings, resolution formats, and zoom settings, which can
alter the displayed video output.
For optimal results, make adjustments to the source video through
the Nº502 Media Console to take advantage of its superior video
processing capabilities.
To help minimize the variables that can affect the display format,
verify the following setup conditions before you start
troubleshooting:
Note
•
Verify that the display and DVD player are set to a generic,
normal, or standard setting that does not add any formatting to
the displayed image. This minimizes the amount of formatting
that the DVD player and the display add to the source image and
simplifies potential troubleshooting.
•
Verify that all zoom modes on the Nº502, display, and DVD
player are set to Normal mode.
When the input format is DVI or analog, the input resolution is 480i or
480p, and the input source is a fullscreen or letterbox DVD, in order to
view the image correctly the DVD player must be set to a mode that
adds the black bars on the left & right sides of the image and the Nº502
must be set to a 16:9 aspect ratio.

Troubleshooting & Maintenance
Mark Levinson
To use the troubleshooting tables:
1. Find the table with the same Input Source as you are using.
2. Use the Symptoms and Output descriptions to identify the
format issue you are troubleshooting.
3. Use the Possible Solution descriptions to identify and solve the
format issue.
Note
Input Source
The Front Panel Display of the No502 does not reflect display format
issues. Therefore, if the Main Zone display has a formatting issue and the
No502 front panel display does not show the same issue, the problem
must lie with the setup of the Main Zone display.

• Image is not stretched or squashed
• No black bars
• Image is not stretched or squashed
• Image has small black bars on the
top & bottom (letterboxing)
4-12
• This is a correct image. All format settings are
correct as set.
• The black bars (letterboxing) are part of the DVD
image. In most cases, the black bars are included
on these DVDs because the original movie was
filmed in a wider widescreen format than the 16:9
aspect ratio displays available for home theater
system.
• The first Output image is typical of a 16:9 aspect
ratio; the second Output image is typical of aspect
ratios greater than 16:9.
• Image is squashed vertically, so
that people appear short & fat
• Image has too much letterboxing
on the top & bottom
• This image is NOT formatted correctly.
• The DVD player may be set to the wrong aspect
ratio.
• The Nº502 may be set to the wrong display format.
• Image has black bars on the left &
right sides (pillarboxing)
• Image is stretched horizontally, so
that people appear tall & thin
• This image is NOT formatted correctly. On a
widescreen source, there should NEVER be black
bars on the left & right sides.
• The display may be incorrectly set. If the display
settings are the issue, the front panel display of the
Nº502 should be showing a correct image.
• It’s normal for widescreen aspect ratios that are less
than 16:9 to have some pillarboxing.
• Image has black bars on the left &
right sides (pillarboxing)
• Image is NOT distorted
• This image is NOT formatted correctly. On a
widescreen movie, there should NEVER be black
bars on the right & left sides.
• The display may be incorrectly set. If the display
settings are the issue, the front panel display of the
Nº502 should be showing a correct image.
• The Nº502 may be set to the wrong aspect ratio.
• It’s normal for widescreen aspect ratios that are less
than 16:9 to have some pillarboxing.

• Image is not stretched or squashed
• Image is complete, no cropping at

image area available.
• Image is stretched horizontally, so
that people appear tall & thin
• Image has too much pillarboxing
on the right & left sides
• This image is NOT formatted correctly. For a
fullscreen source, the left & right bars should
ALWAYS be present and the image should not be
distorted.
• The display may be incorrectly set.
• Image fills the screen, but some of
the image is cropped or missing
• No black bars on the left & right
sides
• This image is NOT formatted correctly.
• A stretch mode or zoom mode may be set on either
the display, DVD player, or Nº502 setup. Verify all
stretch and zoom modes are set to normal.
• Image has black bars on the top &

Rack Mount Kit Instructions
Follow these instructions to install the Nº502 Media Console into the
optional rack mount. To order a rack mount kit, contact an authorized
Mark Levinson dealer for availability and pricing.
1. Using a Phillips head screwdriver, install the rack shelf to the rack
using four of the screws included in the rack mount kit.
Note
Be sure to tighten all screws so that they fit firmly. Ensure that you do NOT
overtighten the screws. Overtightening the screws may strip the threads,
thereby making the connection not secure.
2. Slide the Nº502 Media Console onto the rack shelf until the front
panel is flush with the edges of the rack.
3. Position one of the dress plates included with the rack mount kit
across the top of the Nº502 and screw to the rack using two of the
screws from the kit.
4. Position the second dress plate across the bottom of the Nº502 and
screw to the rack using the last two screws from the kit.
A-6
You have now completed the rack shelf installation. The finished
assembly occupies six rack units. The slots in the rear of the rack shelf are
designed for cable management.

Understanding Room Correction
The Nº502’s Room Correction calibration is a powerful tool for optimizing
the sound of your home theater system. We’ve included this section to
provide a little background information explaining why correcting the
room is so important for optimal sound quality.
Sound Wave
Behavior
The listening environment greatly impacts both the way that you hear
sound and the actual sound wave behavior. Outdoors, in the “open air”,
sound typically travels in straight lines, as there is little to obstruct the
sound. However, a room has walls, a floor, and a ceiling, as well as
furniture, door openings, windows, and people – all of which reflect the
sound waves and create resonances within the room.
A reflected sound wave, or reflection, means that a sound wave
bounces, or “reflects”, from any object only once.
Resonance is the phenomena of multiple reflections at a specific
wavelength. All rooms have resonances because sound waves always
reflect from the hard surfaces – the walls, ceiling, and floor – of the room.
Sound Waves in
a Room
A-12
In a typical listening room, you hear only a small amount of the sound
directly from the speakers. Most of the sound you hear is reflected off of
the walls, floor, and ceiling, in addition to reflections from the furniture,
windows, door openings, and people present in the room.
DIRECT SOUND
REFLECTED SOUND
To put it simply, think of sound waves as moving objects. The wavelength
of audible sound can be as long 54 feet (20Hz) or as short as 0.667 inches
(20kHz). A good general principle to remember is that if the wavelength is
longer than the size of the object, the wave will pass around the object as
if it wasn’t there. If the wavelength is shorter, strong reflections will occur.
For example, the wavelength of 100Hz is 11 feet, so it will pass around
any person standing in a room. However, the wavelength of 1kHz is only
1.1 feet, so it will bounce, or reflect, off of almost everything solid –
people, walls, furniture – in its path. In short, what this means is that
while the 1kHz sound wave has lots of scattered reflections within the
room, the 100Hz sound wave will actually resonate more because its
wavelength is closer to the size of the room.
Nº502 Media Console
Appendix
The lower frequencies tend to behave in predictable ways because the
wavelengths are larger than the typical objects in a room. The mid and
high frequencies generally behave differently from room to room because
the foot-by-foot and inch-by-inch details differ dramatically from room to
room. For example, no two rooms have the same placement of chairs,
tables, lampshades, bookshelves, or people.

VERSUS

A-13
The strength of each reflection, and the end effect of the resonance,
depends upon how the wavelength of the sound compares to the size and
shape of the reflecting object. A small wavelength will have strong
reflections from a large object, while a large wavelength will pass around a
small object with very little reflection. The surface of the reflecting object
can also have a strong effect on the reflections. For example, a smooth
surface, like a cabinet face, will reflect very differently from a sculpture
that has many different edges to scatter reflections. A good visual example
of this effect is the way light reflects from a faceted diamond, which
scatters the light from its many surfaces, versus how light reflects from a
mirror, where the light bounces back in the same path.
The strength of the sound wave reflections can also be affected by the
transmission properties of the reflector. For example, depending upon its
size and stiffness, a wall may have its own resonant frequency. This can
happen when a sound wave of sufficient amplitude hits the wall and
causes it to resonate.
Parallel walls can create very strong reflections because the same
wavelength bounces between them multiple times. The multiple copies,
or reflections, of the same waveform are “added together” when they
reach the listener, but the phenomenom does not necessarily produce
louder sound. The relative timing between the multiple copies can
produce phase shifts, meaning that there may be delays in how long it
takes some of the reflections to reach the listener. These delays mean that
the phase of the waveform will not match exactly and hence some reflections may actually subtract instead of add to the overall sound level. The
Appendix
Mark Levinson
end result of this effect is that you hear an extremely complicated sum
that cannot be easily characterized, but that contributes to the resonances
that create the overall “room sound”.
PARALLEL
REFLECTIONS
How Speakers
Compensate
A-14
Good speaker designers know that there are inevitable differences from
one room to another that they cannot control. So they try to develop
speaker systems that will take best advantage of the known features in any
room. For example, a typical cone driver does not radiate all frequencies
evenly in all directions. With a floor-standing speaker, designers know
how far above the floor each driver in the speaker will be and they take
that height into consideration.
But no matter how good the speaker design is, the designer is still forced
to make assumptions on how the typical home theater is set up and where
the speakers will be placed; and it’s entirely possible, perhaps even
probable, that your home theater will vary greatly from the designer’s
vision of the typical room.
Therefore, for best results, avoid setting up your home theater room in a
manner that creates problems that the speaker designer couldn’t anticipate. Here are some tips for arranging your listening room for optimal
sound enjoyment:
•
If the room is still under construction, try to avoid building large
enclaves or rectangular cavities such as foyers, bay windows, stairway
entrances, and so on. Such spaces resonate specific frequencies that
can greatly affect the sound quality within the room.
•
Try not to place speakers in cabinets or build them into walls unless
the manufacturer has specified them for such applications.
•
Seats should be positioned away from walls and corners. Seating
positions too close to one or more walls are subject to bass increases.
•
Speakers designed to be freestanding should be used that way;
likewise, those designed to be set against a wall or in a corner should
be used that way. Every close boundary wall provides a boost in the
Nº502 Media Console
Appendix
bass, so a speaker placed inappropriately will produce either
insufficient or excessive bass.
This last point is very important. In most speaker designs, high-frequency
sound is directional, while low-frequency sound is omnidirectional. If
you’ve ever stood behind a speaker, this phenomenom is quickly apparent
as you’ll hear more bass than anything else. High frequencies are usually
projected in front of the speakers, while the bass, or low frequencies,
radiate in all directions.
So a speaker set in a corner will reflect the bass from both walls, while the
treble, or high frequencies, are not reflected from the corner walls at all.
Some speakers are designed to be placed in a corner and are hence
designed to accommodate for the expected wall reflections. If one of these
speakers is then placed freestanding away from the wall, the bass will not
be adequate because it will not have the corner reflections to “boost” the
bass sound.

Room Modes
Room modes are resonances that occur when sound wave frequencies
reinforce each other as they reflect back and forth betweeen the hard
boundaries – the walls, ceiling, and floor – of the room. The size and
shape of the room determines which specific frequencies resonate.
A typical room exhibits many room modes. The resulting “sound” of a
room is the addition of all the room’s modes. Since not all room modes
have a positive effect, the room “sound” tends to be complicated. Other
factors, such as wall stiffness or the position of furniture in the room, can
also have an effect on the room’s resonances. At higher frequencies, these
effects become less predictable and can change as people move around
the room. However, at low frequencies, the modes are predictably
consistent due to their long wavelengths, which means that
low-frequency mode problems can be mitigated.
Appendix
How Room
Modes Affect
the Listener
Mark Levinson
Room modes affect the frequency response you hear in several ways. The
most pronounced effect of room modes is to make certain frequencies too
loud. But the most difficult to solve is the tendency of some resonances to
linger in the room after the speaker has stopped vibrating. A very strong
resonance can linger as long as half a second and in the worst cases, the
sound will also have a distinct pitch.
These lingering resonances are not always noticed by listeners because the
frequencies are usually too low to be discernible as a detail unless the
listener specifically listens for them. But they do present a serious problem
because the lingering sound often obscures the following details of the
music or soundtrack. For example, the lingering sound from a kick drum
could mask the details of the following vocal passage. Subjectively, you
might feel as if you were listening to the music through a layer of gauze.
You might try to fix things by adjusting the overall volume or by tweaking
your audio controls. However, none of these fixes can provide satisfactory
results as each can cause detail loss in other areas.
For example, turning down the bass sufficiently to solve the problem with
the kick drum requires all of the bass frequencies to be turned down,
which could leave the rest of the score with too little bass.
Correcting
Room Modes
A-16
The too-slow decay of a resonance mode can be corrected only by
applying the proper filter. The severity of a resonance mode is defined by
its “Q” value, or Quality Factor. The higher the Q of a resonance, the
bigger its amplitude and the slower its decay. Proper treatment of a
resonance requires a filter with not only the correct frequency and depth,
but also the correct Q.
The Room EQ calibration of the Nº502 identifies room resonances and
measures both their Q and frequncy in a highly precise manner. Using
this information, the calibration then applies the proper parametric filters
to neutralize these resonances.

Surround Sound Issues
Surround sound is a key component of modern multimedia
presentations. An action movie DVD may have great video, but the
moving image of an explosion offers little thrill to the viewer without an
accompanying BOOM! A tire-screeching vehicle entering the field of view
from the left is more effective if the accompanying audio also comes from
the left. The surround sound system is what makes it all work; hence,
properly setting up the surround sound system is essential. In most
installations, the seating positions pose a bigger problem than the system
setup.
The two key adjustments for each speaker are timing and level. The subtle
differences in timing of the sound coming out of each of several speakers
is what gives you, the listener, a sense of direction. These subtle timing
differences can be as short as a few milliseconds. If you are too close to
one speaker in the system, many of the audio effects will seem to come
from only that direction because the sound from the speaker arrives at
your ears too early. Since sound travels a bit faster than 1,100 feet per
second, each foot of travel takes just under a millisecond. So if one
speaker is 5 feet too close to you, its sound will arrive at your ears
approximately 5 milliseconds too early.
The surround processor distance settings allow the surround sound
system to delay the sound from each speaker just enough to realign them
all to each other. Levels must also be balanced because a speaker
positioned too close to you will be too loud compared to the other
speakers.
Perfect settings for level and distance apply to only one position in the
room. For example, if one set is 8 feet from every speaker in the room, no
other location in the room will also be exactly 8 feet from them all. A seat
to the left of that first one might be 3 feet closer to the left side speaker,
and the same amount further away from the right side speaker. No single
set of distances will fit both seat positions. Fortunately, our perception
will tolerate some deviation from “perfect” level and distance settings.
In the figure on the following page, the distance value for the side
speakers is set to a location about midway between the two seats, giving
an error of only 1.5 feet for both side speakers for both seats.
A-17
Appendix
Mark Levinson
Distance value for side speakers
should be set to
this point
When a room has multiple viewing positions, the distance and level
settings will be more accurate if all of those seats are clustered together as
closely as possible.
A-18
If a favorite listening chair must be located in a remote corner of the
room, the listeners will have to choose whether to accommodate the
remote seat or to ignore it. No set of values will work perfectly for
everyone if one or more seats are too far away from the “average”
position. Any compromise to accommodate remote seats will degrade the
audio for everyone.

The main purpose of Link2 is to allow a single “master” device to control
specific functions of other Link2-capable Mark Levinson products.
In order to use Link2, the following conditions must be met:
SLAVEªIN SLAVEªOUT
AMPLIFIER
•
Link2 support is only available for the Mark Levinson Nº502 Media
Console and the Nº400-series Power Amplifiers.
•
All products must have Link2 communication ports.
Refer to the product documentation of each Mark Levinson product to
verify compatibility and cabling requirements.
AMPLIFIER
SLAVEªIN SLAVEªOUT
To use Link2, all devices are daisy-chained together using Cat. 5 Ethernet
cables, as demonstrated in the figure on the left. Each “chain” can have
only one “Master” device; all other devices in the chain become “Slaves”.
Slave devices receive and respond to the commands of the Master device.
AMPLIFIER
SLAVEªIN SLAVEªOUT
The Link2 protocol can support a maximum of one Master and eight
Slaves in a chain. The Nº502 Media Console can only be used as a Master
device. The power amplifiers must be Slave devices.
Ensure that all components are powered Off before connecting the Link2 ports.
AMPLIFIER
SLAVEªIN SLAVEªOUT
Once connected, power on the linked components one at a time to
ensure proper functioning of the Link2 controls. The Nº502 Media
Console must be powered on first.
Allow each component to complete the initialization sequence before
proceeding to the next component. Once all components are powered on,
verify that the front panel Standby LEDs on the linked components are
blinking in unison.
The Nº502 can perform the following Link2 functions:
•
Synchronized LEDs – the Standby LEDS of the Nº502 and all linked
amplifiers should blink in unison.
•
Standby Link – the state of the Nº502 Standby mode is replicated by
all linked amplifiers. When the Nº502 is taken out of Standby mode,
the amplifiers should also come out of Standby mode. Likewise, when
the Nº502 is put into Standby mode, the amplifiers should also go
into Standby mode.
•
Fault Condition Reporting – if a linked power amplifier
experiences a fault condition, it’s reported on the Nº502. If this
occurs, the power amplifier number and the fault condition code are
displayed. The power amplifier number refers to its position in the
chain. For example, AMP1 refers to the first amplifier in the chain.
Refer to the product manual of the amplifier for a description of the
fault condition code.
