FEATURES
compatible Mclntosh Control Center by sending a signal to the MC500 POWER CONTROL
IN connector on the rear panel.
The ON position turns on the MC500 as long as its power cord is connected to a live AC
outlet.
POWER GUARD
The patented Mclntosh POWER GUARD circuit prevents the MC500 from ever being driven
into clipping. This protects you from distortion and possible speaker damage. The POWER

INPUTS
CONNECTING CABLES
Use high quality connecting cables. Your Mclntosh dealer can advise you on the types
and lengths of cables that will work best in your installation.
The MC500 has input facilities for both Balanced and Unbalanced cables. Use either
type of input, but not both at the same time.
STEREO

STEREO UNBALANCED INPUTS
Connect shielded cables with RCA type connectors from the outputs of a Preamplifier, Con-
trol Center or similar accessory unit to the Unbalanced Inputs of the MC500
STEREO BALANCED INPUTS
It is possible for unbalanced interconnecting cables to pick up interference from other equip-
ment, AC cables or electrical appliances. Using Balanced cables will provide an additional
40dB of protection against such hum or noise interference.
If two MC500 amplifiers are used in Bridged Mono as a stereo pair, use the Balanced In-
puts to avoid the possibility of ground loop hum pickup,
Use 2 conductor shielded cable with XLR type connectors. The MC500 Balanced Input
connectors are Female, requiring a Male connector plug.
