McIntosh MCC406M, Owner'S Manual

4

Important Information

1. An optional McIntosh External Subwoofer Rotary Control,

Model Number R1163,

 is available from your McIntosh

Dealer.

2. 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.

3. For additional connection information, refer to the owner’s

manual(s) for any component(s) connected to the MCC406M
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 MCC406M can accept

speaker level inputs at its
Input Jacks. Refer to the
diagram for connection.

Performance Features

Introduction

•••••

Power Output

The MCC406M consists of six separate power amplifier
channels, with four channels each capable of 50 watts and
two channels each capable of 100 watts with less than
0.005% distortion.

•••••

Six Bridgeable Channels

The MCC406M includes four 50 watt amplifier channels.
Each pair of channels can be set in bridged configuration
for 200 watts output into a 4 ohm Loudspeaker. The two
100 watt channels may also be bridged for 400 watts out-
put into a 4 ohm Loudspeaker.

Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MCC406M Power Amplifier.
The MCC406M has 400 watts of combined power output
with high current capability from six, five, four or three
channels and will drive any high quality Loudspeaker Sys-
tem to its ultimate performance. The MCC406M reproduc-
tion is sonically transparent and absolutely accurate. The
McIntosh Sound is “The Sound of the Music Itself.”

•••••

High Current Output

A peak output current of 20 amperes ensures that the
MCC406M will successfully drive high quality Loud-
speakers, such as McIntosh, for a truly exciting sound ex-
perience.

•••••

Variable Crossover Filters

The 12dB per octave high pass filters have variable corner
frequencies from 5Hz to 5,000Hz and 12dB per octave low
pass filters with variable corner frequencies from 50Hz to
5,000Hz.

•••••

Illuminated Watt Meters

The MCC406M has Output Watt Meters that display the
combined output in watts for all six channels. The meters
respond 95% full scale to a single cycle tone burst at 2kHz.
It is almost ten times faster than a professional VU meter.

•••••

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 MCC406M 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.

•••••

Thermal Protection with Multi-Speed Cooling Fans

Built-in thermal protection circuits guard against overheat-
ing which could shorten the normal long life expectancy of
your McIntosh Power Amplifier. Cooling fan speed is con-
trolled 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 auto-
matically switch to a higher speed for increased cooling.

•••••

Subwoofer Output Remote Control

An optional Subwoofer Remote Control Accessory may be
connected to the MCC406M and allows varying the
Subwooofer output level.
