• Power Output
The MA6500 consists of two separate power amplifier
channels, each capable of 200 watts and a sophisticated
control center in one compact unit with less than 0.005%
distortion.
••

• Power Guard
Both channels include the patented McIntosh Power Guard
circuit that prevents the amplifier from being overdriven
into clipping with its harsh distorted sound that can also
damage your valuable loudspeakers.

Digital Logic integrated circuits drive Electromagnetic
switches on all six inputs and operating functions for reli-
able, noiseless, distortion free switching.
••
••
• Speaker Switching
Front panel Speaker push-buttons control two switched out-
puts that allow you to send signals to two separate pairs of
loudspeakers.

McIntosh Sentry Monitor power output stage protection cir-
cuits ensure the MA6500 will have a long and trouble free
operating life. Built-in thermal protection circuits guard
against overheating.
