The MC 7108, Eight Channel, 5-Way Power Amplifier can be operated in five different con-
figurations. Each of the eight channels can be operated individually, in Mono pairs or Bridged
pairs into either 8 or 4 ohm loads. Each of the 8 channels of the MC7108 can produce 40
watts into a 4 ohm load. Each of the 4 bridged pairs can produce 100 watts into 4 ohm loads.

CHANNEL MODES
Each of the four pairs of channels has a three position MODE switch. In STEREO mode, each
channel can be operated as a separate mono amplifier, or as four stereo pairs. In MONO mode,
the two (separate) stereo signals are combined to mono in each channel. The volume level of
each mono channel of the pair can be controlled by its own LEVEL control. The BRIDGED mode
combines the two channels in bridged configuration as described above.
Operating configuration Number 1 is ideal for a multi-area remote controlled audio system.
The four pairs of channels make an ideal power amplifier to operate the four remote areas
controlled by a Mclntosh CR10 Remote Control System.
Operating configuration Number 1 is also ideal for a Mclntosh Home Theater System using
the MC7108 together with a Mclntosh C39 or MX 130 Audio/Video Control Center. A rear panel
connector accepts a 25 conductor computer type cable that will connect to a C39 or MX130
A/V Control Center to receive all six channels of audio for a Mclntosh Home Theater System.
Each of the six audio signals are fed to six of the MC7108 channels in the order specified
in the manual section describing the rear panel connections.
Operating configuration Number 4 is ideal for a Mclntosh Home Theater System using the
MC7108 together with the Mclntosh MX 118 Audio/Video Tuner Control Center. The five Dolby
Surround Pro Logic™ processed soundtracks are reproduced in the following manner. Three
bridged 100 watt pairs can be used for the Left Front, Center and Right Front loudspeakers.
The remaining two 40 watt channels can be used for the Left and Right Surround loudspeakers.
INTRODUCTION
The MC7108 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, mounting shelf ventilation cutout and amplifier dimensions are shown in the diagrams
found on a page further back in 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.
