INTRODUCTION
Mclntosh Laboratory has earned a world wide reputation tor the technical superiority of
its contributions to high quality sound reproduction. The advanced level of Mclntosh product
innovations has integrity proven by time. The legendary reliability of Mclntosh products is a
matter of record since 1949. The "Classic Mclntosh" design is acknowledged as the most
outstanding in the audio industry.
Mclntosh products are designed to be maximum "User Friendly". Anyone can enjoy using
them. Ease of maintenance is another Mclntosh design philosophy that contributes to the
long useful operating life of all Mclntosh products.
The MX130, A/V Tuner Control Center is a full featured remote control center tor a complete Mclntosh Home Theater System. It provides six audio channels with the added features
of video switching.
The MX130 includes all the required Dolby Pro Logic™ decoding circuits to reproduce
Dolby Surround™ encoded movie soundtracks.
You also can enjoy the enhanced movie sound track reproduction possible from Home
THX® Audio processing circuits by having your Mclntosh dealer install the optional Mclntosh
THX-M Module in your MX130. The Home THX® Audio System is a licensing program of
Lucasfilm Ltd., which defines new technologies and quality standards for accuracy in home
theaters. The MX130 includes a built-in noise generator and the controls necessary for accurate volume level calibration of all six channels when setting up a home theater.
The MX130 has the added feature of the Mclntosh designed "HALL" signal processing
circuits. The "HALL" feature allows you to enhance the realism of two channel program
sources such as a compact disc. The Left and Right signals are reproduced through the Left
and Right Front loudspeakers. The same signals are combined and fed to the center channel
loudspeaker as mono center fill. The combined left and right are also fed to a digital processor with variable time delay for the surround loudspeakers. If a subwoofer is used in the
system, it will also operate in the "HALL" mode.
The MX130 includes a 25-pin connector on the rear panel to fit a single subrniniature "D"
computer type cable that fits a similar connector on a Mclntosh MC7106 six channel power
amplifier. This cable carries all six audio signals and AC power control to the MC7106 for
a complete Mclntosh Home Theater System.
The MX 130 has built-in capability for remotely controlling two separate listening areas. The
LISTEN signals are defined as Area "A" which is usually the main area where all the equipment is located. The RECORD signals are available at a pair of outputs marked AREA B OUT,
and can be used for a remote area with its own dedicated power amplifier and pair of speakers.
The desired program can be selected in Area "B" with the MX130 Hand Held Remote Controller transmitting to a wall mounted IR sensor, or from a WK-1 or WK-2 keypad.
Data ports are provided for twelve audio and video remote controlled accessories. This
feature allows you to control a compatible unit by transmitting with its hand held remote controller directly to a MX 130 sensor. Another data port connects to the optional Mclntosh HC-1
Home Controller to allow control of accessories or appliances.
The optional Model RCT-1, Remote Control Translator is also available to interconnect with
the MX130. The RCT-1 is a learning device which will allow the MX130 to remotely control
other brands of products.
The convenience of MX 130 remote control operation is enhanced by its capability to directly
interface with the Mclntosh CR10 Remote Control System. The CR10 can add an additional
four remote areas of control.
The MX130 includes twelve pairs of high level audio inputs in addition to the built-in AM-
6
FM tuner. Eight individual AM and FM station presets are available. Seven inputs are for traditional audio program sources, including the built-in Tuner. A pair of low level inputs is included for a moving magnet phono cartridge. Six of the audio inputs are for the audio portion
of an audio/video signal. Six matching standard and S Video inputs are also included. The
MX130 will simultaneously switch the six video and corresponding audio signals.
The MX130 uses digital Logic integrated circuits to drive Electromagnetic Switches for all input, output and operating functions. This is the most reliable and distortion free switching available.
Separate Record and Listen circuits allow recording from one source while listening to
another with audio or audio/video signals. A continuously variable Active Loudness control
allows loudness compensation to be selected for any setting of the volume control. The
Loudness control circuit elements are removed from the circuit path when the control is in
the flat or fully counterclockwise position.
Bass and Treble tone controls provide 12dB of boost or cut. At the center "Flat Response"
or detent position of the tone controls, all tone control circuit elements are removed from
the signal path. Other features include a precision digitally driven six channel volume control, front panel digital volume level indicator and Balanced outputs for the Left and Right
output signals.
Front panel Camcorder inputs and a headphone output are also provided. These connections are hidden behind a motor driven door which is opened and closed by a convenient
front panel Access pushbutton. The Mclntosh MX130 "Classic Mclntosh" all glass front panel
has all control, switch and pushbutton nomenclature illuminated.
The Mclntosh Home THX Audio licensed MX130 A/V Control Center, MC7106 six channel
power amplifier and a set of Mclntosh HT Series Home Theater loudspeakers will make a
perfect "Mclntosh Quality" Home Theater system. Your Mclntosh dealer can assist you
in setting up all the various components of your Mclntosh Home Theater to ensure you will
receive the best possible performance.

The MX130 can be placed upright on a table or shelf, standing on its own plastic feet. It
also can be installed in an optional Mclntosh L74 equipment cabinet. Follow the mounting
instructions enclosed with the L74 cabinet.
The MX 130 can be custom installed in a piece of furniture or cabinet of your choice. The
required panel cutout and unit dimensions are shown on a page near the back of this manual.
Always provide adequate ventilation for your MX130, even though it develops very little
heat. Cool operation insures the longest possible operating life for any electronic instrument.
Do not install your MX 130 directly above a heat generating component such as a high power
amplifier. In a system stack, the power amplifier should always be at the top. If all the components are installed in a single cabinet, a quiet running ventilation fan can be a definite asset
in maintaining all the system components at their coolest possible operating temperatures.
A custom cabinet installation should provide the following recommended minimum spacing dimensions for cool operation. Allow at least 1-1/2 inches (3.8cm) above the unit so airflow
is not obstructed. Allow 17-1/2 inches (44.5cm) depth behind the mounting panel, which includes clearance for connectors. Allow 1-1/8 inches (2.9cm) in front of the mounting panel
for knob clearance.

THE MX130
HOME THEATER
AUDIO
CHANNEL
CONFIGURATION
WITH DOLBY
PRO LOGIC™
AND HOME
THX® AUDIO
Ail movies produced by major film companies have soundtracks that are encoded with
Dolby Surround Sound. The decoding process is called Dolby Pro Logic and results in four
separate soundtracks which are Left Front, Center, Right Front, and Surround sound. The Dolby
Pro Logic decoded surround signals are monaural, but are reproduced by a non directional
loudspeaker on each side of the listening area. The Dolby Surround concept is the heart of
the Home Theater audio and video experience.
Dolby Surround encoding is also used for MTS and satellite broadcasts as well as other
audio-only program sources such as compact discs. Use the MX130 CINEMA 1 mode with
its Dolby Pro Logic processing to enjoy listening to these other program sources.
Home THX Audio circuits further process all the Dolby Pro Logic decoded signals including
the generation of separate spatially expanded left and right surround signals. Home THX Audio
also specifies that a subwoofer should be used. A Home THX Audio system therefore requires
six discrete audio channels and six corresponding loudspeakers.
The MX130 provides six audio channels to take full advantage of the exciting sound
reproduction capabilities of a Dolby Surround encoded movie soundtrack. When the Mclntosh
THX-M module is installed in the MX130, the audio enhancements possible by Home THX
Audio signal processing also will be available.
Descriptions of the functions of each channel of a Dolby Surround soundtrack as decoded
by Dolby Pro Logic and the addition of Home THX Audio processing, will help you in better understanding the use of the various controls, switches and operating procedures of your MX130.
DOLBY SURROUND, LEFT FRONT and RIGHT FRONT
These two channels are stereo channels in the traditional sense. The left and right signals
provide ambience, depth and spaciousness for reproduction of music and sound from a Dolby
Pro Logic decoded movie soundtrack. The front channels also reproduce similar information
from a two channel stereo source such as a compact disc or audio tape.
DOLBY SURROUND, CENTER FRONT
Dolby Surround movie soundtracks are encoded with a Center channel, which also includes
dialog information, to increase the realism of the home theater experience. The Dolby Pro
Logic decoded Center channel is reproduced through a loudspeaker placed in the front center
location, either above or below the viewing screen. A Center loudspeaker provides greater
intelligibility of a movie dialog and also contributes to the overall sound realism.
DOLBY SURROUND, LEFT and RIGHT
Dolby Surround movie soundtracks are encoded with a specially processed surround sound
signal. When decoded by Dolby Pro Logic processing circuits, the surround sounds can include all types of acoustical information and sound effects that enhance the listening enjoyment of a movie. The Dolby Pro Logic decoded surround sound channel is monaural, however,
it is reproduced through two separate loudspeakers placed on the left and right walls of the
listening area. The surround loudspeakers should radiate sound in a non directional manner,
allowing the listeners to hear only the sound that is reflected off the wall surfaces and not
directly from the loudspeakers. Properly installed surround loudspeakers will provide ambience,
and should not distract from the direct sound reproduced by the front loudspeakers.
HOME THX AUDIO SURROUND CHANNELS
Home THX Audio circuits add additional processing to all the original Dolby Pro Logic
decoded signals. The monaural surround signal is further processed into two separate spatially
expanded left and right surround signals.
There are specific Home THX Audio requirements for surround sound level calibration. This
8
information is included in the manual section "MclNTOSH HOME THEATER SURROUND
SOUND VOLUME LEVEL CALIBRATION."
SUBWOOFER
Home THX Audio spediciations require a subwoofer to be used in a home theater system.
A subwoofer loudspeaker is designed to reproduce only the lowest audio frequencies, which
are essentially non directional. The MX130 meets this requirement by combining the Left,
Right and Center channel signals and feeding them through a filter that allows only the bass
frequencies of 80Hz and lower to be fed to the subwoofer outputs. The non directional sound
characteristics of a subwoofer allow it to be placed in a wide range of room locations.
A well designed subwoofer will reproduce the low frequency music and sound effects present in today's action movie soundtracks with dramatic impact. Using a discretely placed
subwoofer also allows the optional use of slightly smaller front loudspeakers.

Control.
LOUDNESS control, (small inner knob): Provides frequency response contoured to Conn-
12
pensate for the behavior of the human ear at softer listening levels. At the fully counterclockwise detent position, the frequency response is perfectly flat and the loudness circuit
components are removed from the signal path. Turn the control clockwise to modify the frequency response in the correct proportion required for softer listening levels. The compensated frequency response is not affected by changes in the volume control settings. First
adjust the VOLUME Control for the desired listening level, then adjust the LOUDNESS Control to the setting you personally prefer.
The LOUDNESS Control affects the LEFT FRONT, CENTER. RIGHT FRONT SUBWOOFer
Unbalanced, LEFT and RIGHT Balanced outputs and the corresponding outputs on the 6
CHANNEL Connector. These are Area "A" Outputs. The LOUDNESS Control is effective in
all five modes of operation.
The VCR1, VCR2, TAPE 1, TAPE 2 and Area "B" Outputs are not affected by the LOUDNESS
Control.
NOTE: The flat frequency response setting of the LOUDNESS Control is at the FULLY
COUNTER CLOCKWISE position, not at the center or 12 o'clock position where the
BALANCE Control is neutral.
M. SYS CAL (SYStem CALibrate)
Allows the volume level of all six channels to be accurately set using the built-in MX130
noise generator. Calibration includes individual channel volume adjustment or trimming which
may be required due to room geometry or differences in amplifiers or speakers. The calibration can be done by automatic or manual switching of the noise generator to each channel,
depending on the setting of the MX130 rear panel SURROUND CALIBRATE switch. The chosen
level calibration settings are then retained in the Control Center memory.
Surround sound calibration is possible in the HALL, CINEMA 1 and CINEMA 2 Modes.
Normal listening levels and surround calibration volume levels can be set as you desire
for HALL or CINEMA 1 Modes. For CINEMA 2 or Home THX ® Audio Mode, the requirements are more specific. Refer to the manual section "MclNTOSH HOME

antenna for urban or high signal strength areas. Extend the two dipole sections as straight
as possible. The antenna can be tacked behind the enclosure cabinet, placed under a rug
or along the wall. Since the antenna is directional, you may have to experiment with the correct position for best reception of your favorite FM stations. An indoor antenna may not prove
effective in houses or buildings with metal siding or insulation.
2. An all channel (UHF-VHF-FM) antenna can be connected. This type of antenna will be
similar to the flexible dipole in reception, but may be more convenient to install.

3. An outdoor antenna designed specifically for the FM broadcast band is the best for optimum reception in all areas. In fringe areas, a directional FM antenna with a rotor is recommended. A rotor allows you to position the antenna for the best possible reception of a specific
FM station. Consult your Mclntosh dealer for assistance if you decide to install an outdoor
FM antenna system.
4. A signal from your local cable company can also be connected- Consult your Mclntosh
dealer and the cable company for installation assistance.
15 and 16. AUX (Auxiliary) and PH (PHono)
Both the PHono and Auxiliary inputs are selected by the same position on the front panel

When the MX 130 is packed for shipping, the AM loopstick antenna is folded flat and taped
against the rear panel. Remove the securing tape and fold it out, away from the panel for
proper AM reception. The AM loopstick antenna is directional so it is designed to be easily
moved to a wide range of positions. This allows you to move the loopstick to the position
for the best possible reception of your favorite AM stations.
19. L and R BALANCED OUTPUTS
Connect cables with XLR type Balanced Connectors from the MX 130 L (Left) and R (Right)
BALANCED OUTPUT jacks to the balanced input jacks of the power amplifier. Signals at the
BALANCED jacks are present whenever the MX130 Area "A" is on and operating, and are
the same signals as at the Unbalanced Left Front and Right Front Outputs.
Using balanced connectors and cables can reduce noise and interference by as much
as 40dB. This extra noise reduction can be a significant improvement, especially if the cables
are quite long.
If two separate mono power amplifiers are used with the MX130 to reproduce the
Left and Right Front signals, balanced cables can eliminate the possibility of hum
pickup.
If cable lengths between the MX130 and the power amplifiers are one meter or less, you
may find high quality unbalanced cables to be satisfactory.
Balanced Jack Pin Configuration:
Pin 1. System Ground
Pin 2. + Output
Pin 3. - Output

modes. The subwoofer always operates in CINEMA 1 and CINEMA 2 modes, regardless of
22
this switch setting.
29. HIGH PASS FILTERS
Set the switch to ON to remove all low frequencies below 80Hz from the Left Front, Center
and Right Front speakers. This mode of operation is preferred when all three front speakers
are small and compact. A Subwoofer will then be necessary to handle all bass frequencies
of 80Hz and lower. The ON position also automatically switches the SUBWOOFER channel
ON, regardless of other switch settings. Set the switch to OFF when full range front speakers
are used. The HIGH PASS FILTERS switch functions in all operating modes.
30. CHANNEL OUTPUT
This connector accepts a 25 conductor shielded subminiature "D" male-to-female computer type cable that feeds all six program signals and the AC power control signal to the
matching 6 channel (THX) connector on the rear panel of the Mclntosh MC7106 six channel
power amplifier. A single cable connection between the MX130 and MC7106 makes an easy
and convenient installation for a Mclntosh Home Theater system.
31. DATA PORTS
The 14 DATA PORTS provide data signals to be fed to compatible audio and video accessories. This allows you to control the accessory components with their own remote controllers transmitting to an MX130 sensor.
The HOME DATA port is provided for connecting to the HC-1 Home Controller. This allows
you to control accessories such as lights or viewing screen motors.
The SUM DATA port is used for connecting to the Mclntosh Model RCT-1 Remote Control
Translator. Any IR signal transmitted to a CR39 sensor results in data signals at this port.
The RCT-1 is a learning device that will allow the MX130 to remotely control most major brands
of accessory components.
All cables connected from the DATA ports use shielded wire with 1/8" mini phone
plugs. Connections are to the sleeve and tip of the plug.
32. EXTERNAL SENSORS (AREA A and AREA B)
Connect a coaxial cable from the AREA A EXTERNAL SENSOR coaxial connector to an
R649 Wall IR Sensor, WK-1 or WK-2 Keypad. This allows the MX130 Remote Controller to
send control signals to the MX130 for Area "A" functions without aiming it at the MX130
front panel. An example would be if the MX130 were installed behind a cabinet door that
would block the front panel sensor.
Connect a coaxial cable from the AREA B EXTERNAL SENSOR connector to an R649 Wall
IR sensor or Keypad installed in the remote Area "B". This allows you to turn on Area "B"
and select all the available system operating modes and program selections in Area "B".
Area "B" must have its own dedicated power amplifier and speakers.
All coaxial connections use either RG59U or RG6 coaxial cable. As many as four
Keypads or Sensors can be connected in parallel on each coaxial cable.
33. CD1/CD2 CONTROL

34. VIDEO INPUTS, SAT, TV, LV, VCR1, VCR2, and V-AUX (S or Standard)
Connect coaxial cables from the video outputs of six separate video accessories to the
appropriate video inputs. These six video inputs can be selected by either the LISTEN, Area
"A" switch, or the RECORD, Area "B" switch. The corresponding audio signals are also
selected simultaneously.
Use either S or Standard Video connectors for all inputs and outputs. Do not mix
connector types.
35. AM ANTenna
A DIN connector socket is provided to allow an external AM antenna to be added for greater
AM signal pickup sensitivity. This can be either a long single lead wire, or a shielded loop cable.
Connect a long line AM antenna to terminal number "4" on a male 7 pin DIN plug and
insert the plug into the AM ANTenna socket on the MX130 rear panel.
A shielded loop consists of a length of shielded microphone cable or coax cable, arranged
in a single turn loop. For best reception, orient the loop vertically. It may be attached around
the frame of a window, behind a curtain, on the back of the equipment cabinet or in some
similar manner. Signal strength is proportional to the size of the loop. The larger the loop,
the greater is the signal strength.
To prepare the loop antenna from the shielded cable, strip 3/4 of an inch of outer insulation
from each of the cable ends. At one end, completely remove the 3/4" of shield, since the
shield is not connected at this end of the cable. Then remove 3/8" of insulation from the center
conductor. On the other end of the cable, leave the shield intact and strip 3/8" of insulation
from the center conductor. On this end only, twist the center conductor and the shield together
so they make a good electrical connection.
At the cable end with the exposed center conductor and no shield, connect only the center
conductor of the cable to terminal number "4" on a male 7 pin DIN connector plug. Connect
the other end of the cable, with the center conductor and shield connected together, to terminal number "7" on the DIN plug. Terminal number "7" is also chassis ground. Insert the
DIN plug into the AM ANTenna socket on the MX130 rear panel to connect the loop.

the MX130 TO MULTI-ROOM CONNECTOR to the matching connector on a Mclntosh CR10
Remote Control System. With a CR10 connected, as many as four additional remote areas
can be controlled. CD2, TUNER, TAPE 1, TAPE 2 and PH/AUX can be used by the CR10. All
signals selected by the MX130 LISTEN, Area "A" switch are fed to the VIDEO inputs on the

A Home Theater combines the newest high fidelity surround sound audio concepts with
the high quality video reproduction of the latest big screen TV sets and monitors. All the excitement of the special audio and video effects of today's action movies are now possible
in your own home using a laser video disc player or VCR as a source.
All movies produced by major film companies have soundtracks that are encoded with
Dolby Surround Sound. The decoding process is called Dolby Pro Logic and results in four
separate soundtracks which are Left Front, Center, Right Front, and Surround. This concept
is the heart of the Home Theater audio experience.
Lucasfilm Ltd. has developed a process for enhancing the reproduction of Dolby Pro Logic
movie soundtracks by adding additional signal processing to all the Dolby decoded soundtracks. This process is called Home THX Audio.
To experience the maximum pleasure from your Mclntosh Home Theater System, the electronics and loudspeakers should be set up as closely as possible to the recommended configurations. You may find it convenient to take advantage of the technical knowledge and experience of your Mclntosh dealer to assist you in the setup procedure.
Reproducing Dolby Surround movie soundtracks with Dolby Pro Logic decoding requires a
specific selection and location of loudspeakers. If you are using the optional Mclntosh THX-M
module in your MX130 for Home THX Audio processing, the requirements are even more specific.
Mclntosh has introduced the HT Home Theater line of loudspeakers specifically designed
for home theater use. These loudspeakers include models for Left Front, Center and Right
Front, Surround Sound and a Subwoofer. The Mclntosh HT Series loudspeakers are licensed
for Home THX Audio, and are ideal for reproducing Dolby Surround encoded movie soundtracks using Dolby Pro Logic decoding as well as Home THX Audio processing enhancement.
These loudspeakers also reproduce normal stereo music sources such as a compact disc
with outstanding fidelity.
Mclntosh is also manufacturing the Model MC7106, six channel power amplifier, specifically
designed for Home Theater use. The MC7106 is also licensed for Home THX Audio and includes a convenient 25 conductor THX connector that accommodates a computer type cable
to receive all six audio channels and AC power control from a matching connector on an
MX130 Control Center.
Dolby Pro Logic decoding produces four specific channels of audio information from a Dolby
Surround encoded soundtrack. These channels include Left Front. Center, Right Front and
Surround sound.
The front left and right loudspeakers provide the fundamental two channel stereo music
and sound. The center channel is also called the dialog channel since it reproduces soundtrack dialog information. A center channel greatly increases the intelligibility of spoken dialog.
The three front loudspeakers should have wide horizontal sound dispersion to allow the
effective area for audience participation to be spread as wide as possible in the home theater
room. The vertical acoustic dispersion of the front speakers should be restricted to avoid
floor and ceiling reflections that could interfere with the indirect reflected surround sounds.
The Dolby Pro Logic decoded surround sound signal is mono, but requires two separate
loudspeakers. One is mounted on the left wall of the listening area and the other on the right
wall. They should be approximately at or slightly above ear height. For the correct ambience
effect, surround sound must be non directional and reflected from the room wall and appear
to come from all directions, rather than heard directly from the loudspeakers.
The addition of a subwoofer can greatly enhance the enjoyment of your home theater. A
subwoofer can reproduce the exciting low frequency music and sound effects of today's action

movies with a dramatic impact. Since a subwoofer is inherently non directional, it can be
placed in a variety of room locations. A good subwoofer also allows the optional use of smaller
and less conspicuous loudspeakers in the front and center locations.
Home THX Audio specifies that a subwoofer be used. The MX130 includes the required
circuits to feed the correct bass signals of 80Hz and lower to the output that feeds the subwoofer power amplifier.

(as seen from the side)
HOME
THEATER
LAYOUT
The front speakers must be aimed directly at the
listening area, This is due to their vertical directivity,
which greatly enhances dialog intelligibility and image localization.
The Surround speakers must be even with and above
the listener. This ensures that the audience hears only
ambient, reflected sound from the Surround channels,
and can never localize them independently.

LEVEL
CALIBRATION
The Mclntosh MX130 has a convenient built-in noise generator to allow trimming volume
levels tor each of the six channels. This process is described as Surround S o u n d Calibration. These selected volume levels are then retained the MX 130 Control Center memory. (The
Dolby Reference Level is 200mV at the input.)
MANUAL CHANNEL CYCLING FOR CINEMA 1 DOLBY PRO LOGIC SURROUND LEVEL
CALIBRATION
1. Set the MODE Switch to CINEMA 1.
2. Set the MX130 VOLUME control to a level indication of 30% ± 10%.
3. Set the rear panel SURROUND CALIBRATE Switch to MANUAL.
Press the SYS CAL surround level calibration pushbutton. This starts the built-in noise
generator and feeds it first to the LEFT FRONT channel to begin the level calibration process. Each further press of the SYS CAL pushbutton feeds the noise generator signal to the
other five channels in the following order: CENTER, RIGHT FRONT, RIGHT SURROUND, LEFT
SURROUND and finally the SUBWOOFER.
Adjust the levels of each of the six individual channels with the front panel UP ( ) or DOWN
( ) SURR LEVEL pushbuttons until you achieve the level match you prefer in the listening
area. It is recommended that all channel volume levels be as close to the same as possible.
Any changes made in channel calibration levels will be read as a TRIM number on the
front panel % VOLUME indicator. Trim numbers will indicate + (Plus) or - (Minus) from 0
to 19. You may repeat the calibration process as often as desired until you are satisfied with
the results.
After the last channel, the Subwoofer, has been calibrated, press the SYS CAL
pushbutton again to exit the calibration mode.
You can also exit or cancel the calibration mode at any time by adjusting the front
panel VOLUME control or pushing one of the remote controller VOLUME pushbuttons.
The dimensions and shape of the listening room can affect bass frequencies that are
reproduced by a subwoofer. You may have to experiment with different locations for the subwoofer until you find one that works best in your room.
(For future reference, list the final calibration trim numbers in the space provided in this
manual. If the MX 130 AC power cord is disconnected from the AC power line, or AC power
is interrupted, the backup power supply will turn off and calibration memory will be lost. The
calibration process must then be repeated.)

1. Set the MODE Switch to CINEMA 1.
2. Set the MX130 VOLUME control to a level indication of 30%, ± 10%.
3. Set the rear panel SURROUND CALIBRATE Switch to AUTO.
4. Press the SYS CAL Surround Level calibration pushbutton to start the automatic channel
cycling for the calibration process. The built-in noise generator turns on and automatically
feeds a signal for two seconds, to all six channels in the following order: LEFT FRONT, CENTER,
RIGHT FRONT, RIGHT SURROUND, LEFT SURROUND and SUBWOOFER.
When either the UP ( ) or DOWN ( ) SURR LEVEL pushbutton is pressed during Automatic

channel cycling, the channel switching function will temporarily stop to allow the level to be
adjusted. One second after an UP ( ) or DOWN ( ) SURR LEVEL pushbutton has been pressed
and then released, the automatic switching will continue to the next channel.
Adjust the levels of each of the six individual channels with the front panel UP ( ) or DOWN
( ) SURR LEVEL pushbuttons until you achieve the level match you prefer in the listening
area. It is recommended that all channel volume levels be as close to the same as possible.
A convenient method for surround volume level calibration in the Automatic channel cycling mode, is to use the UP ( ) or DOWN ( ) pushbuttons on the MX130 Hand
Held Remote Controller and operate it from a position located in the listening area
at seated ear height. First press the SYS CAL pushbutton on the MX130 front panel
to start the automatic process.
Any changes made in channel calibration levels will be read as a TRIM number on the
front panel % VOLUME indicator. Trim numbers will indicate + (Plus) or - (Minus) from 0
to 19. You may repeat the calibration process as often as desired until you are satisfied with
the results.
After all six channels have been calibrated, exit the automatic channel cycling
calibration mode by momentarily pressing either an UP ( ) or DOWN ( ) VOLUME
pushbutton on the Hand Held Remote Controller, or by moving the front panel VOLUME
control.
If the front panel VOLUME control is adjusted, or the remote controller VOLUME
pushbuttons are pushed any time during the automatic channel cycling procedure,
the calibration function will be canceled.

CINEMA 2 HOME THX AUDIO SURROUND SOUND LEVEL CALIBRATION
INTRODUCTION
The design of Home THX Audio amplifiers, preamplifiers and decoders includes careful
control of the signal gains of each of the many circuits involved. Loudspeaker sensitivities,
room size and listening distance will all contribute to the overall playback levels that are correct for the Home THX Audio process.
The built-in noise generator in the MX130 allows trimming volume levels to the desired
Home THX Audio requirements for each of the six channels. This process is described as
Surround Sound Calibration. These selected volume levels are then retained in the Control
Center memory.
After THX calibration is completed, your system, including a Home THX Audio licensed Mclntosh MC7106 power amplifier and HT Series loudspeakers, will reproduce movie soundtracks
from laser video discs at the same levels as heard by the movie producer who mixed the
original soundtracks. Video tape audio levels may vary from those of laser video discs. You
of course may change the overall volume levels to any settings you personally prefer. However,
it is nice to know that by using a Home THX Audio Mclntosh Home Theater System, you can

precisely duplicate the original sound levels specified by the people who produced the movie.
You can use other Mclntosh power amplifiers that do not have an indicated Home THX
Audio sensitivity setting, but you may have to adjust the volume levels on the power amplifiers
to achieve the desired results.
Accurate THX Volume calibration requires the use of a calibrated sound level meter
positioned in the listening area at seated ear height. The meter is necessary to set
the acoustic sound levels from each loudspeaker to 75dB as specified by the Hone
THX Audio standards.
MANUAL CHANNEL CYCLING FOR CINEMA 2 HOME THX AUDIO SURROUND LEVEL
CALIBRATION
1. Set the MX130 LISTEN Selector switch to the LV (Laser Video Disc Player) position.
2. Set the MODE Switch to CINEMA 2.
3. Adjust the MX130 Volume control until the front panel Volume Level Indicator reads
"44". This is the recommended Home THX Audio starting reference volume setting.
This volume setting produces the required audio output when connected to a Home THX Audio
licensed Mclntosh MC7106 power amplifier driving Mclntosh HT Series loudspeakers.
4. Set the rear panel SURROUND CALIBRATE switch to MANUAL.
5. Place the sound level meter in the primary listening area. Set the meter for flat response
or C weighting, slow mode if available, and to an appropriate range for reading a sound pressure
level of 75dB.
6. Press the SYS CAL Surround calibration pushbutton. This activates the built-in noise
generator and feeds it first to the LEFT FRONT channel to start the level calibration process.
Each further press of the SYS CAL pushbutton feeds the noise generator signal to the other
five channels in the following order: CENTER, RIGHT FRONT, RIGHT SURROUND, LEFT SURROUND and finally the SUBWOOFER.
Adjust the levels of each of the six individual channels with the front panel UP ( ) or DOWN
( ) SURR LEVEL pushbutton until the sound level meter reads as close as possible to 75dB
in the listening area.
Any changes made in channel calibration levels will be read as a TRIM number on the
front panel % VOLUME indicator. Trim numbers will indicate + (Plus) or - (Minus) from 0
to 19. You may repeat the calibration process as often as desired until you are satisfied with
the results.
(For future reference, list the final calibration trim numbers in the space provided in this
manual. If the MX130 AC power cord is disconnected from the AC power line, or AC power

LEVEL CALIBRATION
The Automatic channel cycling mode of Home THX Audio surround level calibration is not
recommended since there may not be adequate time to get valid readings from the Sound
Level Meter.
WHEN HOME THX AUDIO CINEMA 2 SURROUND CALIBRATION IS COMPLETED,
A LASER VIDEO DISC WILL PLAYBACK ITS MOVIE SOUNDTRACK IN YOUR MclNTOSH
HOME THESTER SYSTEM AT THE SAME VOLUME LEVELS HEARD BY THE MOVIE
PRODUCER WHO CREATED THE ORIGINAL SOUNDTRACK. THIS WILL ALSO BE THE
SAME LEVEL THAT YOU WILL HEAR IN A THX CALIBRATED MOVIE THEATER. VIDEO
TAPE AUDIO LEVELS MAY VARY FROM THOSE OF A LASER VIDEO DISC.
SURROUND LEVEL ADJUSTMENTS DURING LISTENING
During the actual listening and viewing process of a movie, you may wish to adjust the
LEFT and RIGHT SURROUND sounds to volume levels different from this set during the
calibration process. Do this by pressing the UP ( ) or DOWN ( ) SURROUND pushbutton
on the MX130 Hand Held Remote Controller until you are satisfied with the results. These
changes will remain as long as the MX130 continues to operate.
When the MX130 is turned off, the surround sound volume level changes you made
during listening are canceled and all the original calibrated levels are restored.
If you wish to permanently recalibrate to different surround trim levels, turn off the MX 130.
This will cancel the manual level changes and restore the volume levels set in memory during the most recent calibration process. Then turn the Control Center back on and repeat
the calibration process to put your new preferred surround sound levels in memory.
Do not attempt to recalibrate surround levels after manual adjustment without first
turning the MX130 OFF and then ON, to restore the calibration memory to the original
settings.
If you do not have a sound level meter available, you can calibrate all six channel
levels by ear. You will find the results enjoyable, however, you will not necessarily be
listening at the same exciting volume level as intended by the movie producer.
