internal signal routing, cont’d
Channels 5/6 input switch (P650 and P850) – selects input from three possibili-
ties.
When the switch is in the left position, channels 5/6 receive input from the 5/6 DIN
inputs.
When the switch is in the center position, channels 5/6 receive input from channels
1/2 RCA input.
When the switch is in the right position, channels 5/6 receive input from a summed
input of channels 1, 2, 3, and 4 RCA input. Channel 5 receives the summed input
of channels 1 and 3. Channel 6 receives the summed input of channels 2 and 4.
Channels 7/8 input switch (P850) – selects input from three possibilities.
When the switch is in the left position, channels 7/8 receive input from the 7/8 DIN
inputs.
When the switch is in the center position, channels 7/8 receive input from channels
3/4 RCA input.
When the switch is in the right position, channels 7/8 receive input from a summed
input of channels 1, 2, 3, and 4 RCA inut. Channel 7 receives the summed input of
channels 1 and 3. Channel 8 receives the summed input of channels 2 and 4.
Level controls – Independent level controls for channels 1/2, 3/4,
5/6 and 7/8 adjust the input sensitivity from 90 mV to 5 VRMS.
Note: When crossover 3/4 output is selected for channels 1/2 and 3/4,
the 3/4 level control adjusts the output level for channels 1/2 and 3/4 simultaneously. When
crossover 5/6 is selected for channels 5/6 and 7/8, the 5/6 level control adjusts the output level for
channels 5/6 and 7/8 simultaneously.
Output – Three-position switches determine the output configuration. Each stereo pair of chan-
nels can be configured in either stereo, summed-bridged or 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, ch 4 input is used for
channels 3 & 4, ch 6 is used for channels 5 & 6 and ch 7 is used for channels 7 & 8.
