Output Wiring
All output wiring connections are made to the terminal strip located under the right
side access panel. Loosen the 2 Phillips-head screws on each side of the cover and
remove the cover.

IMPORTANT: Before making any connections or wiring changes to the amplifier
or any equipment connected to the amplifier, make sure that the amplifier is NOT

GND terminal of the output terminal strip. The COM and GND Terminals of the
output terminal strip are connected using a shorting clip. The shorting clip enables
the amplifier output to act as an unbalanced output (one side of the output
connected to ground). If desired, the output can be made to be a balanced output
with no connection to ground. To balance the output, simply remove the shorting
clip. All speaker connections remain the same as above including connecting the
shield to the GND terminal.
