1.5 Ground Switch
Ground On
This setting couples the audio signal's ground to
the chassis ground of the power amps and control-
lers connected to the PB 5.
Ground Off
This setting severs the audio signal's ground from
the chassis ground of the power amps and control-
lers connected to the PB 5 to eliminate humming
caused by ground loops.

You can reverse the pin 2 and 3's pin assignments
of the audio input using the Polarity switch.
In the 2+ position, pin assignments are:
pin 1 = ground, pin 2 = signal (+), pin 3 = signal (-).
In the 3+ position, pin assignments are:
pin 1 = ground, pin 2 = signal (+), pin 3 = signal (-).
