General Notes
1. Connecting Cables are available from the McIntosh Parts
Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo mini
phone plugs on each end.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the MA6500
Integrated Amplifier.
3. There is a built-in turn on delay which will mute the speaker
outputs for approximately two seconds when the amplifier is
turned on.
4. It is very important that loudspeaker cables of adequate size
be used in your music system, to ensure that there will be no
power loss or heating. Cable size is specified in Gauge
numbers or AWG (American Wire Gauge). The smaller the
Gauge number, the larger the wire size:
If your loudspeaker cables are 25 feet (7.62m) or less,
use 16 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 50 feet (38.1m) or less,
use 14 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 100 feet (76.2m) or less,
use 10 Gauge (AWG) wire size or larger.
5. In the event that the MA6500 Integrated Amplifier over heats,
due to improper ventilation and/or extremely high ambient
temperature, the built in protection circuits will activate. The
MA6500 Front Panel Power Guard LED’s will both
continuously indicate On and the audio output signal will be
muted. When the temperature of the MA6500 has returned to
a safe condition, sound will return and the Power Guard
Indicators will return to normal operation.

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.
••
• 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
amplifier.

Installation
Installation
The MA6500 can be placed upright on a table or shelf,
standing on its four feet. It also can be custom installed in a
piece of furniture or cabinet of your choice. The four feet
may be removed from the bottom of the MA6500 when it
is custom installed as outlined below. The four feet together with the mounting screws should be retained for
possible future use if the MA6500 is removed from the
custom installation and used free standing. The required
panel cutout, ventilation cutout and unit
dimensions are
shown.
