- 1 - INSTRUCTION MANUAL McINTOSH MODEL C-8 and C-8P AUDIO COMPENSATORS The McIntosh Audio Compensator is a complete control unit for professional or home entertainment systems. The Model C-8 derives its power from any McIntosh power amplifier: the Model C-8P is self-powered.

UNIT CABLE" on C-8P. Connect audio cable provided between RETMA pin jack labeled "MAIN OUTPUT" on C-8P and 2.5V input of power amplifier. (Socket labeled "PRE-AMP INPUT" on McIntosh power amplifiers.) The Audio Compensator delivers 2.5 volts of audio signal at full output.

- 3 - INPUT CONNECTING PROCEDURE The inherent hum and noise voltages applied to the input of the Audio Compensator are -110 DBM, or less than 3 microvolts. To avoid lowering the sig- nal to hum ratio of the Audio Compensator, by adding hum voltages to the input, extreme care must be taken in its installation.
"INTER-UNIT CABLE" between pins #1 and #2 (pin #1 is ground), and at the RETMA pin jack labeled "MAIN OUTPUT". The inter-unit cable connecting the C-8 to any McIntosh power amplifier uses the octal socket output. The pin jack output may be used for driving a second power amplifier if so desired.

- 10 - VOLTAGE AND RESISTANCE CHART Resistances measured to ground with pin #4 of inter-unit cable socket shorted to pin #1 D.C. Voltages measured with VTVM to ground using D-8 power supply. Signal voltage measured with all controls in flat position, 1000 cycle signal of 10 MV in channel 3, volume control fully on, and with a VTVM.
