7. Ventilation - Locate the instrument for proper ventilation. For example, the instrument should not
be placed on a bed, sofa, rug, or similar surface that may block ventilation openings; or, placed
in a built-in installation, such as a bookcase or cabinet, that may impede the flow of air through
the ventilation openings.
8. Heat - Locate the instrument away from heat sources such as radiators, heat registers, stoves, or
other appliance (including amplifiers) that produce heat.
9. Wall or Cabinet Mounting - Mount the instrument in a wall or cabinet only as described in the owner's

kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc.
11. Cleaning - Clean the instrument by dusting with a dry cloth. Clean the panel with a cloth moistened
with a window cleaner.
12. Object and Liquid Entry - Do not permit objects to fall and liquids to spill into the instrument through
enclosure openings.
13. Nonuse Periods - Unplug the power cord from the AC power outlet when left unused for a long period
of time.
14. Damage Requiring Service Service must be performed by qualified service personnel when:

Mclntosh Laboratory has earned a world wide reputation for its technical contributions to
improved sound reproduction. The technical innovations in Mclntosh products have integrity
proven by time. The Mclntosh "Classic" design is recognized as the most outstanding in the
industry.
Mclntosh products are designed to be maximum user friendly so anyone can enjoy using
them. They are also designed for easy maintenance. The legendary reliability of Mclntosh
products has been a matter of record since 1949.
The MC7106, Six Channel Power Amplifier, is ideal for a "Mclntosh Quality" Home Theater
system. It can also be used in systems where multi amplifiers are needed for remote zones.
All three pairs of stereo channels can be switched into Bridged configuration for 320 watts
each. You have a choice of six 100 watt channels, (160 watts into 4 ohms), four 100/160 watt
channels and one 320 watt channel, two 100/160 watt channels and two 320 watt channels
or three 320 watt channels. The MC7106 configuration is perfect for a home theater system
that will reproduce Dolby SurroundTM soundtracks. The MC7106 has been Home
THX® Audio licensed by Lucasfilm Ltd. to meet all the specialized THX requirements for
reproducing Dolby Surround movie soundtracks. The MC7106 includes a rear panel 25 pin
connector for a computer type cable to accept all six audio channels and AC power control
information from a Mclntosh C39 or MX 130 Audio/Video Control Center. The C39 and MX 130
include built-in Dolby Pro Logic™ decoding circuits, and can be converted to Home
THX® Audio with the add-on Mclntosh THX-M module. The Home THX® Audio System is a
licensing program of Lucasfilm Ltd. which defines new technologies and quality standards
for accuracy in home theaters.
Each of the six MC7106 direct coupled channels can deliver a Peak Output Current of 25
amperes, making it compatible with a wide variety of loudspeakers. All six channels incorporate the Mclntosh POWER GUARD circuit which prevents output clipping with its harsh
and damaging distortion.
There are front panel LED electronic power level indicators for all six channels which ac-
curately read the percentage of maximum power output. The top LED for each channel display
lights whenever the Power Guard circuit is activated. This indicates that the amplifier is being protected from overdrive and clipping. The output level where Power Guard acts will be
well above the rated power due to conservative Mclntosh design philosophy.
The LED power level displays will automatically dim as the room lights dim. A rear panel
control allows you to adjust the LED illumination intensities when they are dimmed, or turn
them off completely. The front panel is "Classic Mclntosh", all glass, with lighted nomenclature.

The amplifier can also be custom installed in a cabinet of your choice. The mounting panel
cutout and amplifier dimensions are shown in the diagrams found on Page 6 of this manual.
Always provide adequate ventilation for the amplifier. The trouble free life of any electronic
instrument is greatly extended by providing sufficient ventilation for proper cooling.

The recommended minimum depth for mounting, including clearance for connectors, is 20
inches (51cm) behind the front mounting panel. Clearance required in front of the mounting
panel surface is 1 inch (2.54cm).
