General Notes

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 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.

Introduction

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.”

Performance Features

·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 Channels

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 Current 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 Crossover 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.
