Troubleshooting
11
Probable Cause:
Amplifier is not connected to
constant power outlet.
Amplifier is not receiving an
audio signal from receiver or
processor
Amplifier fuse might be blown.
The + and - polarity of the sub-
woofer wire might be reversed on
the subwoofer.
Crossover frequency not adjusted
correctly.
L/R line level input is connected
instead of the LFE line level input.
Situation:
No sound from
subwoofer(s)
Performance is less
than expected
Solution:
Make certain the amplifier is plugged
into an unswitched A.C. power outlet.
Make certain there is an audio signal
from receiver or processor and audio
connections resemble those in the
connections section of this manual.
Replace fuse (if fuse is not readily acces-
sible, consult your authorized dealer).
Check the entire system for proper polarity.
Experiment with the phase switch.
Adjust crossover frequency by turning the
crossover frequency control clockwise until
desired sound is obtained.
If bass management is enabled on receiver
or processor make sure to use the LFE line
level input. (See amplifier controls and
setup on the previous page.)
