Mcintosh Laboratory has earned a world wide reputation for the technical superiority of
its contributions to high quality sound reproduction. The advanced level of Mcintosh product
innovations has integrity proven by time. The legendary reliability of Mcintosh products is a
matter of record since 1949. The "Classic Mcintosh" design is acknowledged as the most
outstanding in the audio industry.
Mcintosh products are designed to be maximum "User Friendly". Anyone can enjoy using
them. Ease of maintenance is another Mcintosh design philosophy that contributes to the
long useful operating life of all Mcintosh products.
The C39, Audio/Video Control Center is a full featured remote control center for a complete Mcintosh Home Theater System. It provides six audio channels with the added features
of video switching.
The C39 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 Mcintosh dealer install the optional Mcintosh
THX-M Module in your C39. 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 C39 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 C39 has the added feature of the Mcintosh designed " H A L L " 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 " H A L L " mode.
The C39 includes a 25 pin connector on the rear panel to accommodate a single subminiature " D " computer type cable which fits a similar connector on a Mcintosh MC7106
six channel power amplifier. This cable carries all six audio signals and AC power control
to the MC7106 for a complete Mcintosh Home Theater System.
The C39 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 " B " , 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 HR39 Hand Held Remote Controller
transmitting to a wall mounted IR sensor, or from a WK-1 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 C39 sensor. Another data port connects to the optional Mcintosh 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 C39. The RCT-1 is a learning device which will allow the C39 to remotely control other
brands of products.
The convenience of C39 remote control operation is enhanced by its capability to directly
interface with the Mcintosh CR10 Remote Control System. The CR10 can add an additional
four remote areas of control.
The C39 includes twelve pairs of high level audio inputs. Seven inputs are for all the tradi-
5
INTRODUCTION
INTRODUCTION
tional audio program sources. 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 C39 will simultaneously switch the
six video and corresponding audio signals.
The C39 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 digital 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 Mcintosh C39 "Classic Mcintosh" all glass front panel
has all control, switch and pushbutton nomenclature illuminated.
The Mcintosh Home THX Audio licensed C39 Audio/Video Control Center, MC7106 six channel power amplifier and a set of Mcintosh HT Series Home Theater loudspeakers will make
a perfect "Mcintosh Quality" Home Theater system. Your Mcintosh dealer can assist you
in setting up all the various components of your Mcintosh Home Theater to ensure you will
receive the best possible performance.

The C39 can be placed upright on a table or shelf, standing on its own plastic feet. It can
HOW TO
INSTALL
THE C39
also be installed in an optional Mcintosh L74 equipment cabinet. Follow the mounting instructions enclosed with the L74 cabinet.
The C39 can be custom installed in a piece of furniture or cabinet of your choice. The
required panel cutout and unit dimensions are shown on Page 31 of this manual.
Always provide adequate ventilation for your C39, even though it develops very little heat.
Cool operation insures the longest possible operating life for any electronic instrument. Do
not install your C39 directly above a heat generating component such as a high powered
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.

All movies produced by major film companies have Dolby Stereo soundtracks.
When they
reach you via home video sources, the Dolby Surround encoding remains intact. Dolby Pro
Logic relies on the same decoding technology as the professional cinema processors to
decode the movie sound tracks that are found on video. The decoding process results in four
separate sound tracks which are Left Front, Center, Right Front, and Surround. The Dolby
Pro Logic decoded surround signals are monaural, but are reproduced by a non-directional
loudspeaker on each side of the listening area to help diffuse the sound. 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 C39 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 be used. A Home THX Audio system therefore requires six
discrete
audio
channels
and six
corresponding
loudspeakers.
The C39 provides six audio channels to take full advantage of the exciting sound reproduction capabilities of a Dolby Surround encoded movie sound track.
When the Mcintosh THX-M
module is installed in the C39 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 assist you in better
understanding the use of the various controls, switches and operating procedures of your C39.
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 and localization of a movie dialog regardless of the seating position.
DOLBY SURROUND LEFT and RIGHT SURROUND
Dolby Surround 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 your listening enjoyment. 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 nondirectional manner, allowing the
listeners to hear only a diffused sound. Properly installed surround loudspeakers will provide
ambience, and should not distract from the direct sound reproduced by the front loudspeakers.
H O M E THX AUDIO SURROUND CHANNELS
Home THX 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
information is included in the manual section "MclNTOSH HOME THEATER SURROUND
SOUND VOLUME LEVEL CALIBRATION".
SUBWOOFER
Home THX Audio specifications 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 C39 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 sound tracks with dramatic impact. Using a discretely placed
subwoofer also allows the optional use of somewhat smaller and less obtrusive front
loudspeakers.
Detailed information on Home Theater loudspeaker setup is covered in the manual enclosed with your Mcintosh HT Series Home Theater loudspeakers.

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 Dolby Stereo sound tracks. When they
reach you via home video sources, the Dolby Surround encoding remains intact. Dolby Pro
Logic relies on the same decoding technology as the professional cinema processors to
decode the movie soundtracks that are found on video. The decoding process results in four
separate soundtracks which are Left Front, Center, Right Front, and Surround. The Dolby Pro
Logic decoded surround signals are monaural, but are reproduced by a non-directional
loudspeaker on each side of the listening area to help diffuse the sound. The Dolby Surround
concept is the heart of the Home Theater audio and video experience.
Lucasfilm Ltd. has developed a process for enhancing the reproduction of Dolby Surround
sound tracks by adding additional signal processing to all the decoded sound tracks. This
process is called Home THX Audio.
To experience the maximum pleasure from your Mcintosh Home Theater System, the electronics and loudspeakers should be set up as closely as possible to the recommended
21
HOW TO
SETUP YOUR

HOME THEATER

configurations. You may find it convenient to take advantage of the technical knowledge and
experience of your Mcintosh 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 THX-M module
in your C39 for Home THX Audio processing, the requirements are even more specific.
Mcintosh 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 Mcintosh HT 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.
Mcintosh 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 a C39
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 called the dialog channel since it also 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 surfaces
rather than 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 C39 includes the required curcuits to feed the correct bass signals of 80Hz and lower to the output that feeds the subwoofer power amplifier.

Home THX Cinema Directivity
(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.

(as seen from above)
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.

2. Set the C39 VOLUME control to a level between 3 0 % ± 10%.
3. Set the rear panel SURROUND CALIBRATE Switch to MANUAL.
Press the SYS CAL, (SUR CAL),surround level calibration pushbutton. This starts the builtin noise generator and feeds it first to the LEFT FRONT channel to begin the level calibration
process. Each further press of the SYS CAL, (SUR 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, (SUR CAL) 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 many times as desired until you are satisfied
with the results.
After the last channel, the Subwoofer, has been calibrated, press the SYS CAL, (SUR
CAL), pushbutton again to exit the calibration mode.
You can also exit or cancel the manual 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 sub-
woofer 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 C39 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.)

Adjust the levels of each of the six individual channels with the front panel UP ( ) or DOWN
( ) SURR LEVEL, (SUR CAL) 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

A convenient method for surround volume level calibration in the Automatic mode,
is to use the UP ( ) and DOWN ( ) SURROUND pushbuttons on the C39 Hand Held
Remote Controller and operate it from a position located in the listening area at seated
ear height. First press the SYS CAL, (SUR CAL) pushbutton on the C39 front panel
to start the automatic channel cycling 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

with the results.
After all six channels have been calibrated, exit the automatic calibration mode by
momentarily pressing either an UP (

CINEMA 2 H O M E 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 C39 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
Mcintosh 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 sound tracks. 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 by using a Home THX Audio Mcintosh Home Theater System,
you can precisely duplicate the original sound levels specified by the people who produced
the movie.
You can use other Mcintosh power amplifiers that do not have an indicated Home THX
Audio sensitivity setting, but you may have to make adjustments of the volume levels on the
power amplifiers to achieve the desired results.
26
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 Home
THX Audio
standards.
MANUAL C H A N N E L CYCLING FOR CINEMA 2
HOME THX AUDIO SURROUND LEVEL CALIBRATION
1. Set the C39 LISTEN Selector switch to the LV (Laser Video Disc Player) position.
2. Set the MODE Switch to CINEMA 2.
3. Adjust the C39 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 Mcintosh MC7106 power amplifier driving Mcintosh 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, (SUR 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, (SUR 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, (SUR CAL) pushbuttons 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 many times 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 C39 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.)
After the last channel, the Subwoofer, has been calibrated, press the SYS CAL, (SUR
CAL) pushbutton again to exit the calibration mode.
You can also edit or cancel the manual 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.
If the front panel VOLUME control is adjusted, or the remote controller VOLUME
buttons are pushed at any time during the calibration procedure, the calibration function will be canceled.

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 those set during the
calibration process. Do this by pressing the " U P " or " D O W N " SURROUND pushbuttons on
the C39 Hand Held Remote Controller until you are satisfied with the results. These changes
will remain as long as the C39 continues to operate.
