Connecting the Compressor
Audio Connection
Inputs are actively balanced, and are also capable of
unbalanced operation. The outputs are transformer
balanced, and are capable of driving balanced or
unbalanced lines.
Input connections are made with the female XLR
connectors on the rear of the unit. This connector is wired
with pin 2 HOT, pin 3 common and pin 1 is ground
(shield).
Output connection is made using the male XLR connectors
on the rear of the unit. This connector is wired with pin 2
HOT, pin 3 common and pin 1 is ground (shield).
If you experience hum when using both output connectors
simultaneously, you may have a ground loop. To correct
this problem, disconnect the ground wire (pin 1) from the
XLR cable plugged into the 7802’s output. This interrupts
the ground path and breaks the ground loop, which is
causing the hum.
