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 con-
nectors, is 20 inches (51cm) behind the front mounting panel. Clearance required in
front of the mounting pane! 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 Mclntosh 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 pro-
ducing its maximum undistorted power output, and that you are being protected from over-
drive and clipping. The output level where Power Guard acts will be welt above the rated
power due to conservative Mclntosh 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 Mclntosh
dealer for assistance.)

STEREO: Connect cables from the stereo outputs of a Preamplifier, Control Center or other
accessory component to 7 IN and 8 IN.
