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
subwoofer wire might be
reversed on the subwoofer.
Crossover frequency not
adjusted correctly.
L/R line level input is con-
nected 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
accessible, consult your authorized
dealer).
Check the entire system for proper
polarity. Experiment with the phase
switch.
Adjust crossover frequency by turn-
ing 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.)
