NOTES:
1. Do not connect the McIntosh Amplifier Speaker Negative
Terminal Connection directly to the Vehicle Chassis. Also
do not connect the Loudspeaker Negative Terminal
Connection directly to the Vehicle Chassis. Failure to
observe the connection procedures as outlined in this
owners manual could result in damage to your McIntosh
Amplifier.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the MCC82
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
at least 16 Gauge (AWG) wire size or larger.

Introduction
Now you can take advantage of traditional McIntosh standards of excellence in the MCC82 power amplifier. Two 40
watt high current output channels will drive any high quality loudspeaker system to its ultimate performance. The
MCC82 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the
Music Itself.”
Performance Features
· Power Output
The MCC82 consists of two separate power amplifier
channels, each capable of 40 watts into 4ohm speakers
with less than 0.005% distortion.
·
Two Bridgeable channels
The MCC82 includes two 40 watt amplifier channels
which can be set in bridged configuration for 80 watts output.
4
·
High Current Output
A peak output current of 12 amperes ensures that the
MCC82 will successfully drive high quality loudspeakers
such as McIntosh for a truly exciting sound experience.
· Noise Canceling Inputs
Interference produced by other sources in a vehicle are not
amplified by the MCC82.
· Power Guard
All 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.
·
Sentry Monitor
McIntosh Sentry Monitor power output stage protection
circuits are present on all channels to ensure the MCC82
will have a long and trouble free operating life.
· Speaker Protection
If for any reason, a DC (Direct Current) voltage appears at
the speaker output terminals, a built-in circuit turns off the
amplifier power supplies to prevent damage to your valuable loudspeakers.
Installation
Installation
It is recommended that the MCC82 and any associated mobile audio equipment be installed by a professional who is
skilled in all aspects of installation and operation.
Always provide adequate ventilation for the MCC82.
Be sure to provide at least 1 inch clearance at the sides of
the heatsinks. The amplifier can be mounted vertically or
horizontally and may be located under a seat if adequate
clearance is available. The preferred installation method is
to mount the amplifier directly to the vehicle main frame
using the hardware supplied with the amplifier.
It is not recommended that the amplifier not be mounted
under the hood or in a location where it will be directly exposed to the elements. The openings in the side vents can
be damaged by exposure to water, chemicals or any form
of road dust or debris.
To access the connecting terminals, remove the screws
holding the gold end caps on both sides of the amplifier
and lift the end caps off. The Top Panel Controls and
Switches are accessible by removing the Top Panel by removing the four screws and carefully lifting off the top
panel.

How to Connect the MCC82
How to Connect the MCC82
1. Connect the power control cable from the Control Center Amp On to the MCC82 ON connector on the right
side of the amplifier.
2. Connect cables from two separate loudspeakers to the
amplifier Left and Right terminals, being careful to observe the correct polarities.
4. Connect audio cables from the control center outputs to
the MCC82 Left and Right Inputs.
Note: All cables should be connected to the amplifier before
connecting the DC power cables to the battery.
5. Connect the MCC82 to the vehicle battery terminals
using a minimum size of 10 AWG cables.
Note: If the amplifier is mounted to an insulated mounting
surface, connect a 10 AWG wire (minimum size) from
the amplifier
chassis
directly to
the vehicle
main frame
using the
hardware
shown in
figure 1.

How to Operate the MCC82 in Bridge Mode
In the Stereo Operating Mode, both channels operate as independent full frequency range 40 watt amplifiers application is to drive a full range pair of loudspeakers in the front
section of a vehicle and a second pair in the rear.
The MCC82 can be operated in Bridged Mono Mode for
100 watts into 4 ohms or 80 watts into 8 ohms. The
Bridged mode outputs are floating above chassis ground.
Refer to Figure 3 and 4.
1. Set the MCC82 Mode switch to the Bridged position.
2. Adjust the Left Level control to the X position if using a McIntosh Control Center.
3. Connect the cable from the signal source component
to the Left input.
4. Connect the loudspeaker cables to the appropriate
bridged terminals.
Input Level Controls
The Level controls allow you to set the input sensitivity of
both amplifier channels to provide an ideal match for the
control center being used. The most desirable setting allows the control center to have a useful volume range as
wide as possible from loud to soft. A good measure is to set
the MCC82 level controls so the control center volume is
approximately
at its mid position for normal
listening levels. The Level
controls can be
set for any sensitivity from 3

volts to 0.3
volts. Refer to figure 2.
Power
The MCC82 will turn on or off when the Control Center
turns on or off.
Figure 3
Note: There must be an Amp ON connection between the
MCC82 and the McIntosh Control Center in order for
the amplifier power turn on and off to function.
