How to Operate in Four or Three Channel Mode

How to Operate Four Channel Mode

How to Operate Three Channel Mode

 

 

 

 

 

 

In the 4 Channel Operating Mode, all channels operate as independent 100 watt amplifiers. A typical four channel application is to drive a pair full range loudspeakers in the front section of a vehicle and a second pair in the rear. Re- fer to figures 9 and 10.

In the Three Channel, Tri-amp Mode, channel 1 operates as a 100 watt amplifier for the tweeter, channel 2 operates as a 100 watt amplifier for the mid-range and bridged channels 3&4 operate as a 400 watt amplifier driving a woofer.

Power

Power

The MCC404/MCC404M will turn on or off when the Control Center turns On or Off.

Note: There must be an Amp ON connection between the MCC404/MCC404M and the signal source unit in order for the amplifier power turn On and Off to function.

Input Source

Set the Channel 3&4 INPUT SOURCE Switch to the 3, 4 position for 4 Channel Mode.

Sensitivity Controls

The Sensitivity Controls allow setting of the input level of all four amplifier channels to provide an ideal match for the signal source being used.

Output Mode

Set both OUTPUT MODE Switches to the STEREO posi- tion to configure the amplifier for 4 channel operation.

High Pass Filter

Set the High Pass Filters’ Frequency Controls to 50 and the MULTIPLIER Switch to X.1. This will pass the full au- dible spectrum yet filter out power-robbing sub-sonics be- low 5 Hz.

Low Pass Filter

Set the Low Pass Filter Switches to the OUT position since both channels are operating at full frequency range.

Input Source

Set the Channel 3-4 INPUT SOURCE Switch to 3, 4.

Sensitivity Controls

The Sensitivity Controls allow setting the input level of amplifier channels 1, 2 and 3 to provide an ideal match for the signal source being used. Sensitivity Control 3 adjusts the woofer level balance and Sensitivity Control 4 has no effect.

Output Mode

Set the Channels 1-2 OUTPUT MODE Switch to the STE- REO position. Set the Channels 3-4 OUTPUT MODE Switch to the BRIDGED position.

High Pass Filter

Set both the High Pass Filters’ FREQUENCY Controls to 50 and the MULTIPLIER Switches to X.1.

Low Pass Filter

Set the Low Pass Filter Switches to OUT.
