How to Operate in Four or Three Channel Mode

How to Operate Four Channel Mode

How to Operate Three Channel Mode

In the Four Channel Mode, all channels operate as inde-

pendent 50 watt amplifiers. A typical four channel applica-

tion is to drive a pair of full range loudspeakers in the front

section of a vehicle and a second pair in the rear. Refer to

figures 7 and 8.

Power

The MCC204 will turn On or Off when the Control Center

turns On or Off.

Note: There must be an Amp ON connection between the

MCC204 and the signal source unit in order for the

amplifier power turn On and Off to function.

Input Source

Set the 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.

Mode

Set both MODE Switches to the STereo position to config-

ure the amplifier for four channel operation.

Crossover

Set the CROSSOVER Switches to the OUT position since

all channels are operating at full frequency range.

In the Three Channel, Tri-amp Mode, channel 1 operates as

a 50 watt amplifier for the tweeter, channel 2 operates as a

50 watt amplifier for the mid-range and bridged channels 3

and 4 operate as a 200 watt amplifier driving a woofer. Re-

fer to figures 7 and 8.

Power

The MCC204 will turn On or Off when the control center

turns On or Off.

Note: There must be an Amp ON connection between the

MCC204 and the signal source in order for the

amplifier turn On and Off to function.

Input Source

Set the 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.

Mode

Set the Channels 1-2 MODE Switch to the STereo position.

Set the Channels 3-4 output MODE Switch to the BRidged

position.

Crossover

Set the CROSSOVER Switches to the OUT position since

all channels are operating at full frequency range.
