Your decision to own this piece of Mclntosh Stereo Equipment ranks you at the very THANK top among discriminating music listeners. You now have "The Best". The Mclntosh dedication to "Quality", is assurance that you will receive thousands of hours of musical enjoyment from this unit.
Each channel is coupled to the loudspeaker loads by a Mclntosh Output Autoformer with matched impedances of 2, 4 and 8 ohms. Each channel of the MC500 can produce a peak current output of more than 112 amperes, the highest ever for a Mclntosh stereo power amplifier.

Mclntosh Control Center by sending a signal to the MC500 POWER CONTROL FRONT IN connector on the rear panel. PANEL The ON position turns on the MC500 as long as its power cord is connected to a live AC FEATURES outlet. POWER GUARD The patented Mclntosh POWER GUARD circuit prevents the MC500 from ever being driven into clipping.
Connect cables from each loudspeaker Common or Minus terminal to the MC500. COM (Common) POWER OUTPUT terminals. Connect cables from each loudspeaker Hot or Plus terminal to the desired MC500 2, 4, or 8 (L and R) STEREO POWER OUTPUT terminals Most loudspeakers have their input terminals both marked and color coded.

TRUE POWER OUTPUT WATT METERS TECHNICAL Two illuminated 5-1/2 inch WATT meters are provided on the MC500 front panel. The meters DESCRIPTION are peak responding and their circuits are constantly reading both voltage and current delivered to the loudspeaker loads. The load impedance of a loudspeaker may differ at various parts of the audio frequency range, resulting in a change of output current requirements.
