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 standards of excellence in the MCC404/MCC404M power amplifier. 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 McIntosh 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 configuration 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 variable from 40 Hz to 2,000 Hz that can be either cut or boosted ±12db. 12dB per octave high pass filters with variable 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 valuable loudspeakers.

Installation
Installation
It is recommended that a professional who is skilled in all aspects of installation and operation install the MCC404/ MCC404M and any associated mobile audio equipment.
Amplifier Ventilation
Always provide adequate ventilation for the MCC404/ MCC404M. 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 inches clearance in front of the cooling fans and 1 inch clearance at the sides of the heatsinks.
The cooling fans are controlled by temperature sensors, attached to the interior of the tunnel. The fans are normally off. If the program material contains sustained loud passages demanding high power, the fans will turn-on to increase cooling. If cooling is still not sufficient, additional heating will shut down the amplifier internal power supply completely and the Power Guard LEDs will light. The fans will continue to run and once normal temperatures are 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 amplifier 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 Glass Panel
To access the MCC404/MCC404M Controls, remove the glass panel by removing the four hex bolts with the supplied 3/32” hex key. See figure 2. Attach the supplied suction cup to the top center of the glass panel and carefully raise it high enough to put your hand under. Temporarily place the removed glass panel in a safe place, remove the suction cup and save it for future use.
Removing the End Caps
To access the MCC404/MCC404M 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.
