internal signal routing
2-channel/4-channel input switch - routes RCA input from channels 1/2 to channels 3/4.
When the switch is engaged, channel 1 input is
routed to both amplifier channels 1 and 3 with
input channel 2 routed to amplifier channels 2
and 4.
Switch in the engaged position.
When the switch is disengaged, channels 1, 2,
3, and 4 receive signal individually from their
respective inputs.
Switch in the disengaged position.
Level controls - Independent level controls for channels 1/2 and 3/4 adjust the input
sensitivity from 100 mV to 8 VRMS.
Output - Three position switches determine the output configuration. Each stereo pair of channels can
be configured in either stereo, summed-bridged and bridged-mono.
When the switch is in the left position, the output channels are configured
for stereo operation.
When the switch is in the center position, the output channels are configured for
summed mono bridged operation by mixing the left and right input signals together.
When the switch is in the right position, the output channels are configured
for a bridged mono output using a single RCA input. Ch 1 input is used for
channels 1 & 2 and ch 4 input is used for channels 3 & 4.
