Introduction
The MC-1 can be thought of as four units in one. At its heart is a
reference-quality 8-channel music and film digital audio computer
capable of creating or recreating a limitless amount of listening environ-
ments. This digital audio computer is mated to an 8-channel, 24-bit
Digital-to-Analog converter that rivals the most exotic and costly stand-
alone devices. To harness all of this digital audio power, the MC-1 also
includes a built-in line-level preamplifier with 8 analog audio inputs and
8 digital audio inputs for easy integration with multiple source compo-
nents. Since many of these source components are also capable of
outputting high quality video signals, the MC-1 includes a broadcast-
quality composite and S-video switcher with 8 inputs. The MC-1 also
includes a digital output, two RS-232 ports and three digital audio
expansion ports. The back panel includes a bare wire block terminal for
trigger outputs for easy connection to associated equipment.
The MC-1 is designed to satisfy the most rigorous demands, while
retaining simplicity for casual use as well. Using the system can be as
simple as pressing an input key and turning the volume up and down.
Less-used functions are organized into a simple on-screen menu
system and “hidden” buttons on the remote control. Controls are
provided to accommodate virtually any system configuration and to
allow for varying recording, mixing, and transmission styles, as well as
for system control from a second zone, and for control by sophisticated
automation systems.
The MC-1 includes NIGHTCLUB, CONCERT HALL, CHURCH, and
CATHEDRALeffectsforcreatinganidealcustomlisteningenvironment
as well as MUSIC LOGIC and MUSIC SURROUND which offer ambi-
ence extraction. As these programs use the same Lexicon technology
used by the overwhelming majority of professionals for adding ambi-
ence to their recordings, you will find playback greatly enhanced by the
MC-1, transporting you more deeply into the performance.
The MC-1 also recreates 5.1 channel soundtracks with stunning accu-
racy, and takes them to a new level of realism with Lexicon’s proprietary
Logic 7 technology. These effects allow you to expand 5.1 channel as
wellastwochannelsoundtracksfor7.1andvirtual7.1channelplayback
for an increased sense of spaciousness and envelopment.
The MC-1 provides separate effects for listening to 5.1 channel music
and down-mixing 5.1 channels to two channels, allowing you to fine-
tune the MC-1 for listening to 5.1 channel music or music videos, as well
as recording 5.1 channel sources on 2-channel devices.

soundtracks as well as Surround EX for those recorded in the Dolby
DigitalandDTSdiscreteformats. Theseenhancementsensurethatfilm
soundtracks, which are typically mixed for the acoustics of large
theaters, sound as the filmmakers intended when played back in the
relatively small environment of a home theater.
Using the Documentation
Because the MC-1 is designed to be customized for your system and
your listening space, the information required for installation is exten-
sive.
The Owner's Manual is designed to assist you in installing, calibrating
andoperatingtheMC-1.Itshouldbeusedinconjunctionwiththeremote
control when configuring the system to perform optimally in your
environment. This manual was written with the underlying assumption
that the installer is familiar with audio/video system installation. An
Installation Worksheet is provided at the end of this manual for docu-
mentation of the settings arrived at during the calibration procedure.
Glossary of Terms
Although the MC-1 performs very complex signal processing, a great
deal of effort has gone into making the technology behind the effects as
transparent as possible to the user. To understand the overall organi-
zation of the unit, it is helpful to define those few terms which are unique
to the MC-1.
AC-3 FX The term AC-3 FX (Dolby Digital Effects) is used to describe
all of the effects which are compatible with Dolby Digital input signals.
Any AC-3-capable software and/or source components should be
labeled with a logo, similar to the one on the MC-1 front panel.
DTS FX The term DTS FX (Digital Surround Effects) is used to describe
all of the effects which are compatible with DTS Digital Surround input
signals. Any DTS-capable software and/or source components should
be labeled with a logo, similar to the one on the MC-1 front panel.
Downmix describes the process of creating a two-channel output from
a multichannel (>2) signal. Downmixing is necessary to maintain
compatibility between multichannel formats and devices such as Dolby
Digital and DTS, and two-channel formats and devices, such as stereo
tape decks and VCRs.

Effect An effect is a configuration that determines how the MC-1 will
process an input signal. The MC-1 contains 24 effects: Panorama,
Nightclub, Concert Hall, Church, Cathedral, Party, 2-Channel, Music
Surround, Music Logic, Logic 7, TV Matrix, Pro Logic, THX Cinema,
Mono Logic, 5.1 2-Channel, 5.1 Music, 5.1 Logic 7, Dolby Digital, THX
5.1, DTS 2-Channel, DTS Music, DTS Logic 7, DTS Film and DTS THX
5.1.
Parameter Each Effect has a set of parameters (controls) that charac-
terize it. Parameter settings can be changed to customize each Effect
for your room and listening taste.
Effect Parameter values are stored/recalled with each Effect. Some
examples are: Subwoofer Level and Vocal Enhance
System parameter values are not associated with a particular Effect
andtheirvaluesdonotchangewhenanewEffectisloaded.Anexample
is: Speaker Configuration.
PCM FX The term PCM FX (Pulse Code Modulation Effects) is used to
describe all of the effects which are compatible with two-channel input
signals (analog or digital).
Two-Channel We use the term two-channel rather than "stereo"
because a two-channel input can contain monaural, stereo or matrix-
encoded stereo sound depending on how it was mixed.

Location Considerations
The MC-1 is a highly specialized signal processing computer and
requires special care during installation to ensure optimum perfor-
mance.
The MC-1 may be installed on a shelf or in a standard 19" equipment
rack, using an optional rack-mount kit available from Lexicon dealers.
Observe the following precautions:
•
•
Select a dry, well-ventilated location out of direct sunlight.
Do not stack the MC-1 directly above heat-producing equipment such
as power amplifiers.
•
Avoid placing the MC-1 near unshielded TV or FM antennas, cable TV
decoders, or other receivers. The MC-1 may interfere with some FM
tuners if it is placed immediately above or below them. Some products,
particularly power amplifiers, may cause hum if they are in close
proximity.
•
MakesuretheMC-1frontpanelIRreceiverwindowisunobstructed.The
remote control must be in line-of-sight to this receiver for proper
operation. If line-of-sight is impractical, an infrared remote repeater can
be used with the rear panel IR connector. The MC-1 may be placed in
a glass-doored cabinet but smoked glass will make the front panel
display difficult to read and will reduce the sensitivity of the IR receiver.
AC Connections
The MC-1 is designed to be connected to an uninterrupted AC power
line in the same manner as a VCR or a television. We recommend the
use of an AC line filter to protect against line surges, or the installation
ofalineconditionertoprotectagainstundervoltage(brownouts)aswell
as overvoltage conditions.
The MC-1 has a master power switch on the rear panel above the IEC
standardACpowerreceptacle. ThisswitchmaybeleftONcontinuously
when the unit is in regular use. When the MC-1 will not be used for an
extendedperiodoftime, orwheneveryouareconnectingordisconnect-
ing any cables to the unit, this switch should be turned OFF.
Connect the power cable to the MC-1, then plug the power cord into a
walloutletorintoanunswitchedoutletonasurgeprotector. Besurethat
the power cord is firmly seated in the connector on the rear panel of the
MC-1.

Wiring Considerations
Audio/Video Cables
There is debate over the audible effects of different types of intercon-
nects. Good engineering practices have minimized the effect that
cables might have on the inputs and outputs of the MC-1 — but feel free
to evaluate different interconnects in your system. Be conscious,
however, of the mechanical stress from repeated insertion and overly
tight connectors, and the possibly corrosive nature of some contact-
enhancing fluids.
Note that the use of standard audio cables for video or digital audio
applications may cause signal degradation, and is not recommended.
For these connections, please use only cables that are designed for the
application — these have different impedance characteristics than
cables designed for analog audio applications. Consult your dealer for
recommendations.
All cables should be kept as short as possible.
Speaker Connections
In general, speaker cables should be kept short, and low-impedance
wire should be used throughout to assure efficient power transmission
and avoid audible distortion. Recommended wire lengths are given in
the table below. Although these examples can be used as a general
guide, your system manuals should provide detailed information spe-
cific to your components.

up to 51 feet
Audio/Video Connections
Before making any connections, turn off ALL audio and video compo-
nents, including individual power amplifiers. (Unplug any components
that don’t have power switches.)
The MC-1 is designed to function as the control center of the system,
selectinginputsandcontrollingthevolumeofallspeakersinthesystem.
The following diagram shows a system with a tape deck, an AM/FM
tuner, a CD player with a coaxial digital audio output, a satellite receiver
with an optical digital output, a DVD player and a VHS VCR. This
example shows the tape deck and VCR set up for recording and dual-
zone audio.
Actual system connections will vary widely depending on the compo-
nents used. Consult your dealer for details on your particular require-
ments.

MC-1 Connections
Input sources should be connected directly to the MC-1 inputs.
Connect your main stereo amplifier to the MC-1 FRONT outputs.
Connect any additional amplifiers to the remaining outputs on the
MC-1: side amplifiers to the SIDE outputs, rear amplifiers to the REAR
outputs, center-channel amplifier to the CENTER output and the sub-
woofer amp to the SUBWOOFER output. If you are using di-pole
surround speakers, the amplifier driving them should be connected to
the MC-1 SIDE outputs.
Whenever possible, connect both analog and digital outputs of digital
sources. This enables use of a digital input for the main zone, and the
corresponding analog input for the Record/Zone 2 outputs.

MC-1 Digital Controller
Installation
Video Connections
The MC-1 has eight composite and S-Video inputs. Connection to an S-
Video input will override the composite signal connected via the RCA-
type connector. Note that an S-Video input will be output on both the
composite and S-Video outputs. Composite input signals will not be
output as S-Video.
You can assign any video source to any (or all) of the eight MC-1 inputs
via the Input Configuration submenu of the Setup menu. This can be
very useful in systems which use a VCR as the tuner for TV viewing, as
the video feed from the VCR can be assigned to both the VCR and TV
inputs. The VCR's audio signals can be fed to both inputs with Y-
connectors. (DonotuseY-connectorsonvideosignals.)Thisallowsthe
audio and video signals from the VCR to be used for both TV and VCR
viewing.
You can also assign any video source to audio-only sources such as an
AM/FM tuner, to enjoy music from another source while viewing a video
source.
It is important to remember that the impedance characteristics of
composite video and digital audio are different from analog audio. You
should only use cables specifically designed for video and digital audio.
Consult your dealer for recommendations.
Digital Audio Connections
The MC-1 has eight S/PDIF digital audio inputs: five coax via RCA and
three optical via TOSLINK™. The digital inputs can be set up to be
selected with any (or all) of the eight inputs via the Input Configuration
menu.Usingthedigitalinputswillalwaysprovidesuperiorperformance.
Expansion Port Input Connections
The MC-1 also has three digital audio expansion ports (A, B and C).
These coaxial digital audio inputs are capable of accepting stereo PCM
signals up to 24-bit/96kHz. Expansion Port A feeds the Left and Right
Front channels directly. Expansion Port B feeds the Center and
Subwoofer channels directly, and Expansion Port C feeds the Left and
Right Surround channels directly.
Note: These inputs are designed to completely bypass all of the digital
signal processing of the unit, including the crossovers and effects.
For DVD players that support true 24/96 digital audio outputs, we
recommendconnectingoneDVDdigitalaudiooutput toExpansionPort
A, and another DVD digital audio output to one of the MC-1's eight
S/PDIF digital audio inputs.

Installation
NOTE: Whenever playback of a 24/96 disc is desired, press 2-CH
while holding down the Shift button on the remote control. If you
are using SMALL loudspeakers, these inputs will send a full
frequency response signal to the outputs, completely bypassing
the internal crossovers. Do not use this input with Dolby Digital or
DTS signals.
Whenever playback of non-24/96 discs is desired, select the regular
input on the MC-1 remote control or front panel.
Digital Output
For digital-to-digital audio recording, the MC-1 also includes a coaxial
digital audio output (S/PDIF OUT). Any digital audio input (coaxial or
optical) selected for Record or Zone 2 will be sent directly to this output.
NOTE: Analog audio inputs and the Expansion Port inputs are not
available at the S/PDIF OUT, and the REC/ZONE 2 option in the
Input Configuration menu does not affect the S/PDIF OUT.

Input Gain (Analog Inputs Only)
For optimal performance when using analog inputs, the unit must be
driven to its full input level without clipping. Despite industry attempts at
standardization, different analog sources have a wide range of output
levels.Tocompensateforthis,eachoftheeightMC-1analoginputscan
be assigned a different input gain, assuring optimum performance
regardless of the source. For use with a calibration tone, the Dolby
reference point is indicated by an enlarged tick mark on the Input Level
meters.
The GAIN control is only available
for analog inputs. Whenever a digi-
tal input is selected under AUDIO
IN, this control is automatically
set to OFF.
The MC-1 GAIN function can be set to AUTOMATIC to monitor the
analog input level and automatically optimizes the input gain. If the
signal level is too high, input gain is automatically decreased to a point
which does not cause clipping. When the signal level remains low
(>12dB below clipping for 2.5 minutes), the input gain is increased in
1dB steps to maximize dynamic range.
When MANUAL is selected, the display shows the last auto level
setting. (If the auto level feature has not been used, the display shows
the last manually entered level.) The auto level setting indicates the
optimum input level value as determined by the unit. The ▲ and ▼

TheMC-1V-DISCinputisselected.AmovieencodedinDolbySurround
is put in the laser disc player and starts to play. The LDD-1 recognizes
that the movie is not AC-3 encoded, and automatically routes the laser
disc player's PCM (2-channel digital) signal to the MC-1. The MC-1
identifies the signal as PCM and automatically loads the LOGIC 7 effect
(as specified in the INPUT CONFIG menu).
Now, assume the movie is replaced with one that is encoded in Dolby
Digital (AC-3). When it begins to play, the LDD-1 recognizes the signal
as being AC-3 encoded and demodulates it for the MC-1. The MC-1
automatically loads the 5.1 Logic 7 effect.
The FX ▲ and ▼ buttons are used to audition the other available AC-
3 effects and DOLBY DIGITAL is selected. At some point during the
movie, the PAUSE button on the laser disc player is pressed. This
causes the laser disc player to temporarily replace the AC-3 output
signal with a PCM signal. This change is recognized by the MC-1, which
automatically loads the Logic 7 effect (because in this example, AUTO-
MATIC is selected as the setting of FX FORMAT and LOGIC 7 is
selected as the PCM FX in the INPUT CONFIG menu). Because the
laser disc is paused, there is no audio. When PAUSE is released,
playback is resumed and the MC-1 automatically reselects the DOLBY
DIGITAL effect because it was the last effect selected before the audio
was paused. To go back to the default effect, simply press the input
button.
Now, the movie is replaced with a 5" music disc that is encoded in DTS.
When the disc begins to play, the LDD-1 recognizes that it is not AC-3
encoded, and automatically routes the signal to the MC-1. The MC-1
recognizes the DTS signal and automatically loads the DTS LOGIC 7
effect*.TheFX ▲ and▼ buttonsare usedtoauditiontheotheravailable
DTS effects and DTS MUSIC is selected. At some point, the skip button
onthelaserdiscplayerispressedseveraltimestoadvancetoadifferent
track . This causes the laser disc player to temporarily replace the DTS
output signal with a PCM signal while it searches for the selected track.
This change is recognized by the MC-1, which automatically loads the
Logic 7 effect (because in this example, AUTOMATIC is selected as the
setting of FX FORMAT and Logic 7 is selected as the PCM FX in the
INPUT CONFIG menu). Because the disc player is searching, there is
no audio. When playback is resumed, the MC-1 automatically reselects
the DTS MUSIC effect.* To go back to the effect selected as a default,
simply press the input button.
* As the MC-1 is in AUTOMATIC mode, there may be a brief burst of noise before normal

In the previous example, if PCM ONLY had been selected, rather than

AC-3 Only
When AC-3 ONLY is selected as the FX FORMAT, only AC-3 effects
can be used on that input. Any other type of signal received on that input
will cause the MC-1 to mute and display "NO AC-3 AUDIO." The FX ▲

Audio In
This option in the INPUT CONFIG menu determines which audio input
connector on the MC-1 rear panel will be used for the MAIN zone. Using
the digital inputs will always yield better performance, and these should
be used whenever a source component has a digital audio output. The
options available for AUDIO IN are: ANALOG, COAX (1-5) and OPTI-
CAL (1-3).
Analog
When ANALOG is selected for a given input, the MC-1 will use the
corresponding analog stereo audio input to generate the MAIN OUT-
PUTS. Note that selecting ANALOG will automatically select PCM
ONLY as the FX FORMAT as the AC-3 and DTS effects are only
compatible with digital inputs.
COAX 1-5 and OPTICAL 1-3 (Digital Audio Inputs)
When one of these eight digital inputs is selected, the MC-1 will use it
to derive the signal for the MAIN OUTPUTS. Note that all eight digital
inputs can be used for various MC-1 inputs. This is particularly useful
when using a source component such as a VCR, laser disc or DVD
player to drive multiple MC-1 inputs.
WhenusingaPCMdigitalaudiosourcesampledat48kHz, thefollowing

MC-1 Digital Controller
Record/Zone 2
The MC-1 is designed to be the control center of any system. As such,
there are separate outputs for easy integration of external recording
devices as well as an additional “zone” in multi-room installations.
The Record and Zone 2 outputs on the MC-1 are wired in parallel so that
the input selection will always be the same for both. For example, if the
CD input is selected for Record, the CD input is also output to Zone 2.
The primary difference between the Record and Zone 2 outputs is that
Zone2hasitsownvolumecontrol, whiletheRecordoutputlevelisfixed.
As protection against feedback, the TAPE and VCR inputs are normally
blocked from being used as sources for the Record and Zone 2 outputs.
This default condition can be changed in the Input Configuration menu
as follows.
NOTE: When listening to DTS material
from a source component, DTS digital
data may also be sent out of the analog
outputs. DTS data, which sounds like
loud white noise, may cause damage to
a system.
Use ▲ and ▼ to select REC/ZONE 2, then press SELECT. The ▲ and
▼ buttons will select ANALOG, DIGITAL, or BLOCKED as the state of
the Zone 2 output.
ANALOG allows maximum flexibility from digital sources by utilizing
both the digital and analog outputs of a digital source component
(provided both are connected). The MC-1 processes the digital input
signal for the main zone, and simultaneously routes the analog input
signal to the Record and Zone 2 outputs. Since no D/A converters are
necessary for the analog input signal, the functionality in the Main zone
is not compromised.
DIGITAL routes the digital signal, assigned to the input, to the MC-1’s
24-bit Digital to Analog (D/A) converters. After conversion, the signal is
sent to the Record and Zone 2 outputs. As this setup bypasses the
D/A converters in the source component, and utilizes the 24-bit D/A
converters in the MC-1, sound quality can be dramatically improved
when recording or listening in Zone 2. Note, however, that this setup
automatically loads the appropriate 2-Channel effect in the main zone.
NOTE: Removing the block from any
inputwhichhasbothaninputandoutput
attached to the MC-1 may cause dam-
aging feedback.
BLOCKED simply blocks the input from being sent to the Record and
Zone2outputs. Thispreventsfeedbackfromoccurringwithdevicesthat
have both an input and output attached to the MC-1 (Tape deck, VCR,
etc.).

LIMITER OFF
The MC-1 provides a Subwoofer Peak Limiter that prevents the
subwoofer signal level from exceeding a preset value. The limit is
factory preset to a level of +15dB. This setting can be changed within
the limiter’s operating range of -5dB to +35dB, with -5dB providing
maximum limiting.
To turn off the limiter or to change its setting, select the SUB PK
LIMITER parameter in the Output Levels menu.
If you want to turn the limiter off, first turn the system volume down in
order to prevent the subwoofer from overloading.
Press ▼ to select LIMITER, then press SELECT. Press ▼ to select
OFF. Press DONE twice to return to the Output Levels menu. While
readjusting the system volume back to a comfortable listening level,
check to be sure the subwoofer or its amplifier is not overloading on
passages with loud low frequency peaks.
Selecting LIMITER ADJUST in the Sub Peak Limiter menu invokes a
calibration routine for setting the optimal peak level for your installation.

Speaker Distance
The Speaker Distance control automatically sets the appropriate time
delays for all of the loudspeakers in a system. Although this adjustment
is not a substitute for proper speaker placement, it will help to ensure
accurate signal arrival times from all channels at the listening position.
To set up Speaker Distance, you must physically measure the distance
from the primary listening position to the front baffle of each individual
speaker in your system. An easy and accurate way to accomplish this
is to have a person sit in the primary listening position, holding the end
of a measuring tape, while a second person extends the tape measure
to the front baffle of each speaker in turn.
To enter these values, select SPEAKER DISTANCE in the Listener
Position menu and press SELECT. Use ▲ and ▼ to highlight feet or
meters and press SELECT. Press SELECT again to highlight NEAR-
EST SPKR. Use ▲ and ▼ to enter the actual distance, then press
DONE.

Once you have entered the distance to the nearest speaker, the MC-1
will automatically calculate the maximum allowable distance. The

equal to your nearest speaker. Use SELECT and ▲ and ▼ to highlight
and enter actual distances for each speaker. The MC-1 rounds off
distance settings into discrete steps – choose the closest step to the
actual distance in these cases. If a speaker distance is further than the
MC-1 can accommodate, set it to the maximum allowable distance.
(This will vary, depending on your intial entry for NEAREST SPKR.)
A/V Sync Delay
A/V Sync Delay compensates for the delay that occurs when a video
processor, such as a scan rate converter, is used with the MC-1. Most
of these processors alter the original audio/video timing relationship by
adding delay to the video signal as it is processed. A/V Sync Delay
applies a corresponding delay to the audio signal to restore the original
audio/video timing relationship. It can also be used to compensate for
poorly mastered source material.
If your video material appears to be out of sync, engage A/V Sync Delay
intheLISTENERPOSITIONmenu. Withavideosourcerunning, adjust
the delay along its range with ▲ and ▼.
Notethatitisbesttouseanon-filmsourcewhensettingA/VSyncDelay,

Calibrate Panorama
Panorama works by canceling the sound going from each speaker to
the opposite ear. Its effectiveness is highly dependent on the geometry
of your front loudspeakers, the room and your listening position. The
correct timing of the canceling signal varies with the relative angle
between your main speakers.
Find a mono source, such as an announcer on FM radio or a mono film,
and listen for a tightly focused center image of speech or singing. If the
imageisoff-center,adjusttheMC-1’sinputbalancecontrols. (Themore
centered the monaural image, the better Panorama will work.)

canceling signals to arrive at both ears at the same time you must be
centered precisely between the speakers. It will be easiest to calibrate
this parameter if you start equidistant from the two front speakers, even
if this is not your normal listening position. Once you have heard the

Panorama
Panorama extracts the natural ambience from recorded music and
moves it outward from the speakers, producing greater width and depth
of image and a feeling of enhanced spaciousness. This mode adds no
additionalsoundbutexpandstheexistingstereoimage.Panoramaalso
works well with Dolby Stereo movies, bringing the surround track
outward into the room.
The location of the front speakers and the listening position are crucial
to Panorama’s effectiveness and for best results your system and the
MC-1 together should be set up and calibrated according to the
procedure in Chapter 2. The strength of the Panorama effect drops off
as you move away from the prime listening position, especially to the
sides. Video systems with the L/R main speakers spaced closely on
either side of a TV screen will produce a usable effect over a somewhat
wider area than set-ups with a large angle between the L/R main
speakers.

5 SPEAKER ENHANCE simulates 7 speaker playback through a 5
speaker system, providing a heightened sense of spaciousness and
envelopmentwithoutextraspeakers. Thisenhancementismostnotice-
able if the surround speakers are positionned directly to the side of the
listening position, or if the listening position is located against the rear
wall.
Note that, although this provides very convincing improvement to a 5
speaker system, it is not a substitute for a properly set up and calibrated
7 speaker system. The difference is most noticeable when the listener
is seated to one side or the other of the calibration position.
ACADEMY FILTER is provided to recreate the proper tonal balance of
older monaural films that were recorded with much narrower and duller
frequency response than current films.
AUTO AZIMUTH is short for auto azimuth error correction/automatic
input balance. Auto Azimuth should be set to ON for films, and OFF for
music. When ON, special patented algorithms continually monitor the
input signal and adjust both the relative level and time offset of the two

frequencies (<80Hz) may cause damage to them.
BASS RT (low frequency reverberation time) depends on MID RT and
is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for
a more natural effect in smaller spaces.
CENTER LEVEL adjusts the output level from the center speaker.
EFFECT LEVEL adjusts the loudness of the side and rear speakers.
When there are no side speakers, it adjusts the amount of ambient
signal mixed into the main loudspeakers. In Panorama, this control

FRONT STEERING provides three basic settings which have been
developedspecificallytooptimizecenterchannelsignalstrengthforfilm
and music.
The FILM setting has excellent frontal image stability through the whole
roomduringdialogandvocals, whilepreservingthefullwidthofthefront
image in the spaces between dialog, and for music without vocals. The
front image during vocals is noticeably narrower than with the MUSIC
setting, but highly satisfactory nonetheless.
The MUSIC setting reproduces sound in all three front speakers when
a strongly centered, or mono signal is present. This is an excellent
choice for heavily centered pop music such as metal and sounds more
natural for broadcast material with a single announcer. OFF sets the
center channel level to 4.5dB less than the front left and right speakers,
and then leaves the level unchanged as the steering varies. This setting
is equivalent to conventional stereo with a slight center fill.
HALL SIZE allows you to select room sizes of lengths ranging from 4-
38 meters, depending on the effect selected.
INPUT BALANCE allows you to compensate for the occasional source
with audible channel imbalance. When selected, screen graphics
indicate the relative left/right position.
LIVENESS adjusts the amount of recirculation within the effect. Higher
values mimic more reflective surfaces in the simulated space and
increase the amount of time it takes the sound to decay. At very high
values, the decay is audibly less smooth than in the Church and
Cathedral Effects, which are more effective at simulating very live
spaces.

LOW FREQ WIDTH allows you to apply low-frequency spatial correc-
tion to the signal. Positive values of LOW FREQ Width indicate that the
difference signal (L-R) has additional energy below 500Hz, while the
sum (L+R) has correspondingly less. Negative settings of LOW FREQ
WIDTH can compensate for recordings with too much of this property.
This control can add needed spaciousness and warmth to classical
recordings made with coincident or near-coincident microphones.
MAIN LEVEL controls the level of the mono signal that is reproduced by
the main speakers. When a center speaker is part of the configuration
manyfilmsmaysoundbetterwhenthiscontrolissetbetween6-12. This
spreads the film sound out around the screen and can be more pleasant
than restricting the dialog and much of the other film sound to the center
speaker.
MID RT (midrange reverberation time) is the time required for midrange
sounds to decay 60dB in level.
PRE-DELAY increases the delay between the direct sound and the
onset of reverberation. Because some pre-delay is inherent in the
programmaterial,avalueof0isusuallyagoodstartingpoint.Increasing
the pre-delay value will make the hall sound larger.
RE-EQUALIZER equalizes the left, center, and right channel outputs to
match the overall frequency balance of the original recording. Without
this re-equalization, many films and some television programs will
sound too bright.
REAR DELAY adjusts the amount of time between the appearance of
a signal in the front channels and its emergence from the rear. Gener-
ally, the correct delay is about 16 milliseconds, but the setting depends
on speaker set-up and source material. In general, the delay should be
low enough so that the rear sound does not become identifiable as a
distinct source. The settings also affect the side outputs.
REAR DELAY OFFSET is an additional delay added to the rear
channels. This delay increases the apparent size of the listening space
by increasing the rear delay time. Feel free to experiment to find the
setting that works best.
REAR LEVEL controls the volume level of the rear speakers. Although
we have selected a default value, the correct setting will vary with each
recording, the room, and your personal taste.
REAR ROLLOFF sets the frequency above which the rear-channel
sound is attenuated. The appropriate setting will vary with the program
material. It should be set high enough to give presence and airiness to
the rear sound without placing distracting instrumental overtones or
other sounds behind you. The settings also affect the side outputs.

ROLLOFF mimics the absorption of the air in the hall and, typically,
should begin with a low frequency to simulate large spaces.
SIDE LEVEL controls the volume level of the side speakers. Although
we have selected a default value, the correct setting will vary with each
recording, the room, and your personal taste.
SIDE ROLLOFF provides a high frequency cutoff for the side speakers.
The optimal setting for this control will vary widely with the source
material.
SOUNDSTAGE controls the level of the surround speakers relative to
the front speakers in a dynamic way. The MC-1 attempts to detect
whetherornotthesoundsourcewasoriginallyencodedfromasurround
source by looking for occasional bursts of rear-steered material, and by
identifying the directional orientation of the background sound between
strong sounds. Whenever there is an indication that the source was
originally surround encoded, the Soundstage control automattically
reverts to the REAR setting — which gives the rear speakers full level.
The NEUTRAL position attenuates the rear speakers 3dB. The FRONT
position attenuates the rear speakers 6dB. The effect is to move the
listening position forward in the listening space.
SPEECH DETECT activates a circuit that distinguishes monaural
speech from other inputs. Essentially, this control turns down the effect
to make speech clearer. Whenever stereo signals are present, the right
and left input channels are used independently as inputs to the ambi-
ence synthesis. If there is a strong monaural speaking voice present at
the same time, this component of the input to the effect is reduced while
the stereo component is increased.
If the input signal is pure monaural speech the reverb is almost entirely
attenuated. SPEECH DETECT is a real benefit to some popular music
(where spoken voice, such as rap, occurs along with the music), stereo
television and early stereo movies. Any stereo material which was not
carefully mixed for Surround is a good candidate for playing through the
Nightclub, Concert Hall, Church or Cathedral Effect with speech detect
on.
SUBWOOFERLVL boostsorcutsthesubwooferoutputlevel. Although
the normal subwoofer level is set during the calibration procedure, with
some recordings it may be desirable to increase or decrease this deep
bass level.
SURROUND LEVEL adjusts the loudness of the signals sent to the rear
channels. This control should be set so that the rear is audible without
calling attention to itself. Numerical values and screen graphics are
displayed during adjustment. The settings also affect the level of the
side outputs.

SURROUND ROLLOFF allows the high frequencies of the surround
channels to be attenuated with the same detection circuitry as that
described for the Soundstage control. The attenuation is quite attractive
on many music and broadcast sources which were not mixed for
surround. When a surround source is detected, these filters are re-
moved, so the rear speakers can reproduce surround events with full
bandwidth. This control should be set high enough to give presence and
airiness to the rear sound without placing distracting instrumental
overtones or other sounds behind you. The settings also affect the side
outputs.
SURROUNDS selects the type of surround decoding used by the
MC-1. STEREO provides extraction of five channels of surround infor-
mation from a standard 4-2-4 matrix-encoded soundtrack (Dolby Sur-
round, Ultra*Stereo, etc.) The drama of this effect is dependent on the
source material and is most noticeable with strong stereo music
soundtracks. The DECORRELATED setting electronically alters the
monaural surround channel to provide added spaciousness and envel-
opment.
VOCAL ENHANCE boosts vocals in the center channel. By targeting
specific frequencies, it can boost only vocals, without raising the entire
center channel level (which would alter the output balance achieved
during calibration).

REF OFFSET indicates the Dialog Normalization value that is present
in AC-3 bitstreams. In AC-3, dialog is reproduced at -31dBFS (31dB
below full scale). If the program material was mixed so that dialog is at
-31dBFS, then REF OFFSET=0dB. If the dialog was mixed at a "hotter"
level, for example, -27dBFS, then REF OFFSET = -4dB and the MC-1
would adjust the levels down 4dB to bring dialog back to -31dBFS.

Troubleshooting
If you encounter a problem, please review the items in the following
checklist. Also be sure to thoroughly check all other connected compo-
nents such as speakers, receiver/amplifier/preamp, VCR, TV, CD
player, etc.
Problem
Possible Cause and Solution
Power does not come on
Check line cord to ensure good connection to the AC outlet and to the
receptacle on the MC-1 rear panel. Check to make sure that the MC-1
rear panel power switch is ON.
No audio
Check the Status menu (under DISPLAY ADJUST: ON-SCREEN or
FRONT PANEL menu — or press and hold Record/Zone 2 on the
remote and press OSD ON) to verify that audio is being received.
Remote control not working
No output
Check batteries to be certain that they are inserted correctly with proper
polarity. Make sure that the infrared sensor on the MC-1 front panel is
not obstructed. See "If all else fails..." on the following page.
Make sure that signal is coming into the MC-1. (Check the Status menu
by pressing and holding Record/Zone 2 on the remote, then pressing
OSD ON. This menu will display input level meters and sample rate, if
applicable.)
Increase VOLUME using the remote control and check Front/Back and
Left/Right BALANCE.
Check the MC-1 MUTE controls to make sure they are not engaged.
Check all other equipment settings and connections and verify that the
amplifiers being fed by the MC-1 are operational.
Remember that the MC-1 mutes the output to any speakers which are
not configured in the Setup menu. If speakers are added to (or removed

Hum
Finding and eliminating audio hum in a complex installation can be a
very frustrating task. Often, the easiest way to identify the culprit(s) is to
systematically eliminate devices from the audio chain. If Cable TV is
connected to any component in the system, start by unplugging the
Cable completely, preferably right at the wall jack. If this eliminates, or
greatlyreducesthehum,itisworthacalltoyourCablecompany.Aquick
fix, assuming your cable is round 75Ω wire, is to attach a 75-300Ω
transformer to the end, then attach a 300-75Ω transformer to that, so
that the end is back to a round 75Ω wire. There are commercially
availableantennaleadisolatorswhichmayprovideadditionalinsulation
from electrical surges.
Interference with Radio or TV
The MC-1 does generate minimal amounts of RF energy and is in
compliance with FCC rules and CE standards. If some interfering noise
is noted, move AM loop and FM "T" type antennas away from the
MC-1 and reorient them as necessary. Use shielded cable for FM and
TV antenna feeds.
Erratic recall of modes
If all else fails…
Severe power surges or sags can confuse the MC-1 memory. To
correct, or if you simply want to start over, restore the factory defaults
with the procedure described at the end of this section.
Turn off all amplifiers. Turn the master power switch on the MC-1rear
panel OFF, wait 10 seconds, then turn it ON again. This causes the unit
to run a diagnostic self-test routine which takes a couple of seconds. If
theMC-1LCDdisplaysnormallyattheendofthistest,noproblemshave
been found with the MC-1 circuitry. If the internal tests fail, the LCD may
display an error message, or no message at all. If this happens, contact
your dealer or Lexicon Customer Service.
If you find that your custom settings are routinely being corrupted, the
lithium battery in the MC-1 may need replacing. This part is not field-
replaceable — contact your dealer or Lexicon Customer Service.
If the unit is still behaving erratically, perform the Restore Defaults
procedure described on the following page.
Lexicon maintains a knowledge base on its website
questions and additional troubleshooting information.

Troubleshooting
MC-1 Digital Controller
Routine Maintenance
Other than occasional replacement of the batteries in the remote
control, the MC-1 requires minimal maintenance. Use a soft, lint-free
cloth slightly dampened with warm water to clean the exterior surfaces
of the unit.
Do not use alcohol, benzene or acetone-based cleaners
or any strong commercial cleaners.
Do not use abrasive materials such as steel wool or metal polish. If the
unit is exposed to a dusty environment, a low-pressure blower may be
used to remove dust from the MC-1 exterior.
Restoring Defaults
If severe power surges or sags cause problems with normal MC-1
operation, or you simply want to start with a clean slate, you can restore
all of the factory defults with the following procedure.
This will erase any programs you have stored,
as well as all setup and calibration values.
Note any settings you want to re-use before proceeding.
Turn the MC-1 OFF with the remote. Turn the unit back ON and
immediatelypressandholdMUTEontheremote.(Makesureyoudonot
block the infrared receiver on the MC-1 front panel.) The on-screen
display will read:

To restore defaults, use ▲ or ▼ to highlight RESTORE DEFAULTS,
then press SELECT. This will clear and reload all preset effects and all
factory settings of Volume, Balance, Contrast, Configuration, etc.
When the message FACTORY DEFAULTS RESTORED is diplayed,
press DONE to return to normal operation. All of the adjustable parame-
ters in the MC-1 have now been reset to the values assigned when it
cleared final Quality Control at the factory.
If you cannot solve functional problems through these procedures,
consult your dealer or Lexicon Customer Service.
DO NOT OPEN THE UNIT.
DOING SO WILL VOID YOUR WARRANTY, AND
MODIFICATIONS MAY RENDER THE UNIT UNSERVICEABLE.
