General Notes
1. An optional McIntosh External Subwoofer Rotary Control,
Model Number R1163,
is available from your McIntosh
Dealer.
2. Do not connect the Amplifiers Speaker Negative Terminal
Connection directly to the Vehicle Chassis. Failure to observe
this could result in damage to your Amplifier.
3. It is advisable to place an inline fuse as close as possible to
the battery.
4. For additional connection information, refer to the owners
manual(s) for any component(s) connected to the MCC204
Amplifier.
5. There is a built-in turn on delay which will mute the speaker
outputs for approximately two seconds when the amplifier is
turned on.
6. 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. If your loudspeaker cables are 25 feet
(7.62m) or less, use at least 16 Gauge wire size or larger.
7. The MCC204 Line Level OUTPUTs are wired as a Y
connection with the INPUTs to pass the input signals on to
additional amplifiers (keep cable lengths as short as
possible). The McIntosh MX406 Control Center is capable of
driving several additional
power amplifiers with no
degradation of the signal.
8. The MCC204 can accept
speaker level inputs at its Input
Jacks. Refer to the diagram for
connection.
