General Notes
1. An optional McIntosh External Subwoofer Rotary Control,
Model Number R1163, is available from your McIntosh
ealer.
2. o not connect the Amplifier Speaker Negative Terminal
Connection directly to the Vehicle Chassis. Failure to observe
this could result in damage to your Amplifier.
3. For additional connection information, refer to the owners
manual(s) for any component(s) connected to the MCC404/
MCC404M Amplifier.
4. There is a built-in turn on delay which will mute the speaker
outputs for approximately two seconds when the amplifier is
turned on.
5. 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.
6. It is advisable to place an in-line fuse as close as possible to
the battery.
7. The MCC404/MCC404M 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 MCC404M/MCC404 can
accept speaker level inputs at
its Input Jacks. Refer to the
diagram for connection.
Performance Features
Introduction
·Power Output
The MCC404/MCC404M consists of four separate power
amplifier channels, each capable of 100 watts into 4ohm
speakers with less than 0.005% distortion.
·Four Bridgeable hannels
The MCC404/MCC404M includes four 100 watt amplifier
channels. Each pair of channels can be set in bridged con
figuration for 400 watts output into 4 ohm loudspeakers
with less than 0.007% distortion.
·High urrent Output
A peak output current of 20 amperes ensures that the
MCC404/MCC404M will successfully drive high quality
loudspeakers, such as McIntosh, for a truly exciting sound
experience.
·Equalizer and Variable rossover Filters
The one band equalizer has a center frequency that is vari
able from 40 Hz to 2,000 Hz that can be either cut or
boosted ±12db. 12dB per octave high pass filters with vari
able corner frequencies from 5Hz to 5,000Hz and 12dB per
octave low pass filters with variable corner frequencies
from 50Hz to 5,000Hz.
·Power Guard and Sentry Monitor
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. McIntosh Sentry
Monitor power output stage protection circuits are present
on all channels to ensure the MCC404/MCC404M 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 valu
able loudspeakers.
Now you can take advantage of traditional McIntosh stan
dards of excellence in the MCC404/MCC404M power am
plifier. Four 100 watt high current output channels will
drive any high quality loudspeaker system to its ultimate
performance. The MCC404/MCC404M reproduction is
sonically transparent and absolutely accurate. The McIn
tosh Sound is The Sound of the Music Itself.
