Troubleshooting
Probable Cause:
Situation:
Make certain the amplifier is
plugged into an unswitched AC
power outlet.
Make certain there is an audio sig-
nal from receiver or processor.
Replace fuse (if fuse is not readily
accessible, consult your authorized
RBH Sound dealer).
Check the entire system for proper
polarity. Experiment with the phase
switch settings.
Adjust the crossover frequency by
turning the crossover frequency
control clockwise until the desired
sound is obtained.
If bass management is enabled on
receiver or processor make sure to
use the LFE line level input. (See the
