Your decision to own this McIntosh MA6500 Integrated
Amplifier ranks you at the very top among discriminating
music listeners. You now have “The Best.” The McIntosh
dedication to “Quality,” is assurance that you will receive
many years of musical enjoyment from this unit.
Please take a short time to read the information in this
manual. We want you to be as familiar as possible with all
the features and functions of your new McIntosh.
• 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%
• 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.
• Electronic Input Switching
Digital Logic integrated circuits drive Electromagnetic
switches on all six inputs and operating functions for reliable, noiseless, distortion free switching.
• Speaker Switching
Front panel Speaker push-buttons control two switched
outputs that allow you to send signals to two separate pairs
of loudspeakers.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the MA6500 will have a long and trouble
free operating life. Built-in thermal protection circuits
guard against overheating.
• Illuminated Power Meters
The illuminated power output watt meters on the MA6500
are peak responding, and indicate the power output of the
