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 owners
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 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 LEDs 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.

7. For added protection for this product during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent
damage to the product due to lightning or power line
surges.
8. Do not use attachments not recommended in this
owners manual as they may cause hazards.
AVIS RISQUE DE CHOC NE PAS OUVRIR.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
NO USER-SERVICEABLE
PARTS INSIDE. REFER
SERVICING TO
QUALIFIED PERSONNEL
To prevent the risk of electric shock, do not remove
cover (or back). No user serviceable parts inside. Refer
servicing to qualified personnel.
General:
1. Read all the safety and operating instructions, contained in this owners manual, before operating this
equipment.
2. Retain this owners manual for future reference about
safety and operating instructions.
3. Adhere to all warnings and operating instructions.
4. Follow all operating and use instructions.
5. Warning: To reduce risk of fire or electrical shock,
do not expose this equipment to rain or moisture.
This unit is capable of producing high sound pressure levels. Continued exposure to high sound pressure levels can cause permanent hearing impairment or loss. User caution is advised and ear protection is recommended when playing at high volumes.
6. Caution: to prevent electrical shock do not use this
(polarized) plug with an extension cord, receptacle
or other outlet unless the blades can be fully inserted to prevent blade exposure.
Installation:
9. Locate the equipment for proper ventilation. For example, the equipment should not be placed on a bed,
sofa, rug, or similar surface that may block ventilation
openings; or, placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air
through the ventilation openings.
10. Locate the equipment away from heat sources such as
radiators, heat registers, stoves, or other appliance (including amplifiers) that produce heat.
11. Mount the equipment in a wall or cabinet only as described in this owners manual.
12. Do not use this equipment near water; for example,
near a bathtub, washbowl, kitchen sink, laundry tub, in
a wet basement or near a swimming pool, etc.
13. Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The equipment may fall, causing serious injury to a person, and serious damage to
the product.
Connection:
14. Connect this equipment only to the type of AC power
source as marked on the unit.
15. Route AC power cords so that they are not likely to be
walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit
from the instrument.
16. Do not defeat the inherent design features of the polarized plug. Non-polarized line cord adapters will defeat
the safety provided by the polarized AC plug. If the
plug should fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the grounding-type plug.

Introduction
The MA6500 Remote Controlled Integrated Amplifier is a
simple but elegant instrument that allows you to enjoy outstanding music reproduction. It includes a wide range of
convenient operating functions to enhance your listening
experience. The classic McIntosh MA6500 will perfectly
complement a McIntosh Loudspeaker System for a stereo
system of incomparable performance and style.
Performance Features
· Power Output
The MA6500 combines a 200 watts per channel power amplifier 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 required
panel cutout, ventilation cutout and unit dimensions are
shown.
Always provide adequate ventilation for your MA6500.
Cool operation ensures the longest possible operating life
for any electronic instrument. Do not install the MA6500
directly above a heat generating component such as a high
powered amplifier. If all the components are installed in a
single cabinet, a quiet running ventilation fan can be a definite asset in maintaining all the system components at the
coolest possible operating temperature.
Front View of the MA6500
custom installed
A custom cabinet installation should provide the following
minimum spacing dimensions for cool operation. Allow at
least 6 inches (15.24 cm) above the top, 2 inches (5.08cm)
below the bottom and 1 inch (2.54 cm) on each side of the
amplifier, so that airflow is not obstructed. Allow 21 inches
(53.3 cm) depth behind the mounting panel, which includes clearance for connectors. Allow 1-1/8 inches (2.9
cm) in front of the mounting panel for knob clearance. Be
sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing.
NOTE: In Europe, if the MA6500 is custom mounted, an
additional ventilation opening of 6 inches (15.24 cm) in
height, running the full width of the front panel, needs
to be directly above the front top of the MA6500.
