proven by time. The Mclntosh "Classic" design is recognized as the most outstanding in the

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.

INTRODUCTION

The MC7106 can be placed upright on a table or shelf, standing on its four plastic feet. 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.

Allow at least 1-1/2 inches (3.8cm) above the heat sink area to allow the free flow of air. 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).
