INSTRUCTION MANUAL

McINTOSH MODEL C-108

AUDIO COMPENSATOR

The McIntosh Audio Compensator is a complete control unit for professional
and home entertainment systems. Five input channels are provided; three which
produce constant amplification over the audio spectrum of 20 cycles to 20, 000
cycles, and two which are equalized for use with magnetic phonograph cartridges.

The C-108 Audio Compensator requires an external power source. A
McIntosh 50W-2, 20W-2, or A-116 Power Amplifier, or D-101 power supply may
be used for this purpose.
