The MC 7108, Eight Channel, 5-Way Power Amplifier can be operated in five different configurations. 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.

MC7108 OUTPUT OPERATING CONFIGURATIONS

(4 ohm loudspeaker loads)

1. 8-40 watt channels
2. 6-40 watt channels and 1 - 100 watt bridged pair channel
3. 4-40 watt channels and 2 - 100 watt bridged pair channels
4. 2-40 watt channels and 3·100 watt bridged pair channels
5. 4 - 100 watt bridged pair channels

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 McIntosh CR10 Remote Control System.

Operating configuration Number 1 is also ideal for a McIntosh Home Theater System using the MC7108 together with a McIntosh 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 McIntosh 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 McIntosh Home Theater System using the MC7108 together with the McIntosh 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.

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.

HOW TO INSTALL THE MC7108

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). If mounted in a custom cabinet, cut out a ventilation hole in the amplifier mounting shelf according to the recommended dimensions.

FRONT PANEL DISPLAY

A front panel Red LED indicator is provided for each of the four pairs of channels. This indicator turns on when the speaker relays for that specific channel pair turn on.

All eight channels of the MC7108 incorporate the McIntosh POWER GUARD circuit which prevents output clipping with its harsh and damaging distortion. A front panel LED Power Guard indicator is provided for each of the eight channels. The LED lights whenever the power Guard circuit is activated for any particular channel. This indicates that the amplifier is producing its maximum undistorted power output, and that you are being protected from overdrive and clipping. The output level where Power Guard acts will be welt above the rated power due to conservative McIntosh design philosophy.

(If the POWER GUARD indicators turn on and stay on continuously for any given pair of channels, it indicates a problem is present. If this condition occurs, contact your McIntosh dealer for assistance.)

REAR PANEL ANDHOW TO MAKE CONNECTIONS
