- 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. Five input channels are provided: three which produce constant amplifica- tion over the audio spectrum of 20-20, 000 cycles, and two which are equalized for magnetic phonograph cartridges. THE AUDIO COMPENSATOR IS A COMPLETE PRE-AMPLIFIER AND RECORD COMPENSATOR: THEREFORE, THE USE OF AN AUXILIARY EQUAL- IZER OR PRE-AMPLIFIER WITH THIS UNIT IS NOT RECOMMENDED. INSTALLATION OF MODEL C-8 and C-8P, AUDIO COMPENSATORS The C-8 and C-8P Audio Compensator may be mounted in any type equip- ment cabinet, relay rack panel, door, wall, etc., or in its own cabinet for chair side operation. It is not necessary to disassemble the Audio Compensator for mounting. Cut a rectangular hole in the panel to be used for mounting, insert the Audio Compensator, and secure with wood or machine screws. Mounting tem- plates are provided with this manual for the C-8 and C-8P. When installing the C-8P, the power supply section should be mounted at least two feet from the Audio Compensator. After these units have been secured in their desired location, proceed as follows: 1. Connect speaker to output of power amplifier. 2.
