General Notes
1. Do not connect the Amplifier Speaker Negative Terminal
Connection directly to the Vehicle Chassis. Failure to observe
this could result in damage to your Amplifier.
2. For additional connection information, refer to the owner s
manual(s) for any component(s) connected to the
MCC602TM 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. Use at least 14 Gauge (AWG) wire size
or larger. The speaker output terminals are large enough to
accept 12 Gage wire.
5. It is advisable to place an in-line fuse as close as possible to
the battery.
6. The pin configuration for the XLR Balanced Input connectors
on the MCC602TM. Refer to the diagram for connections.

General Notes, cont
8. The MCC602TM incorporates the very latest in Fully Double
Balanced Circuitry. As a result, the Loudspeaker Negative
Connections are above chassis ground and are not common
between channels. Do not combine any connections together
or ground them.
9. In the event that MCC602TM Power Amplifier over heats, due
to improper ventilation and/or extremely high ambient
temperature, the built in protection circuits together with the
built-in cooling fans will activate. The Power Guard LEDs
will both continuously indicate On and no sound will be
heard. When the temperature of the MCC602TM has returned
to a safe condition, sound will return and the Power Guard
Indictors will return to normal operation.
Introduction
Now you can take advantage of traditional McIntosh standards of excellence in the MCC602TM. Two 300 watt high
current output channels will drive any high quality loudspeaker system to its ultimate performance. The
MCC602TM reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is The Sound of
the Music Itself.
circuit is possible ONLY with the exclusive McIntosh Output Autoformer. The Balanced Input Connections guard
against induced noise and allow long cable runs without
compromising sound quality.
· Patented Autoformers
McIntosh designed and manufactured Output Autoformers
provide an ideal match between the amplifier output stages
and speaker loads of 2, 4 and 8 ohms. The Autoformers
also provide perfect DC protection for your valuable loudspeakers.
· Power Guard
Both channels include the patented McIntosh Power Guard
circuit that prevents the amplifier from being over driven
into clipping, with its harsh distorted sound that can also
damage your valuable loudspeakers.
· Sentry Monitor
McIntosh Sentry Monitor power output stage protection
circuits ensure the MCC602TM will have a long and
trouble free operating life.
Performance Features
· Power Output
The MCC602TM consists of two separate power amplifier
channels, each capable of 300 watts into 2, 4 or 8 ohm
loudspeakers with less than 0.005% distortion.
· Mono Parallel Operation
The MCC602TM can be set in Mono Parallel Operation
with 600 watts output into 1, 2, or 4 ohm loudspeakers with
less than 0.005% distortion. It can also function as two 300
watt amps both amplifying the same mono input signal.
· High Current Output
A peak output current of 50 amperes ensures that the
MCC602TM will successfully drive high quality loudspeakers, such as McIntosh, for a truly exciting sound experience.
· Fully Balanced Circuitry
The MCC602TM amplifier is fully balanced from input to
speaker output. Two matched amplifiers operate in PUSHPULL with their outputs magnetically combined in the
Output Autoformer. Each half of the amplifier contains
complementary balanced circuitry. The resulting double
balanced configuration cancels virtually all distortion. This
· Thermal Protection with Multi-Speed Cooling Fans
Built-in thermal protection circuits guard against overheating which could shorten the normal long life expectancy of
your McIntosh power amplifier. Cooling fan speed is controlled by temperature sensors attached to the interior of
the extruded aluminum cooling tunnel. The fans normally
run at a quiet low speed, when needed the fans will automatically switch to a higher speed for increased cooling.
· Illuminated Power Meters
The Illuminated Power Output Watt Meters on the
MCC602TM are peak responding and almost ten times
faster than a professional VU meter. They also indicate the
true power output of the amplifier regardless of the loudspeaker impedance, as they measure both the voltage and
current going to them.

Installation
It is recommended that a professional who is skilled in all
aspects of installation and operation install the
MCC602TM and any associated mobile audio equipment.
Amplifier Ventilation
Always provide adequate ventilation for the MCC602TM.
The amplifier requires an adequate airflow
into the cooling fans, which are located on the
left side of the amplifier. The warm air exits
the amplifier through vents on the heatsinks.
See figure 1. Be sure to provide at least 1-1/2
Cool Air
inches clearance in front of the cooling fans
and 1 inch clearance at the sides of the
heatsinks.
The cooling fans are controlled by tem-
Figure 1
perature sensors, attached to the interior of
the tunnel. The fans are normally off. If the
program material contains sustained loud pas-
Cool Air
sages demanding high power, the fans will
turn-on to increase cooling. If cooling is still
not sufficient, additional heating will shut
down the amplifiers internal power supply
completely and the Power Guard LEDs will
light. The fans will continue to run and once
normal temperature is restored, operation will
resume.
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 am-
Figure 2
plifier directly to the vehicle main frame using the hardware supplied with the amplifier.
It is not recommended that the amplifier
be mounted under the hood or in a location
where it will be directly exposed to the elements. The openings in the fan housings and
heat tunnel vents can allow internal components to be damaged by exposure to water,
chemicals or any form of road dust or debris.
Removing the End Caps
To access the MCC602TM Connecting Terminal Blocks,
remove the Glass Panel first (the above step) and then remove the Phillips Screws holding the End Caps on both
sides of the amplifier and lift the end caps off. See figure 3.
