TROUBLESHOOTING

If you used the high-level
(speaker) inputs and there 
is no sound from any of the
speakers:

• Check that the receiver/
amplifier is on and a source 
is playing.

• Check that the powered 
subwoofer is plugged into 
an active electrical outlet 
and is switched on.

• Check all wires and connec-
tions between the receiver/
amplifier and the speakers.
Make sure all wires are con-
nected. Make sure none of the
speaker wires are frayed, cut
or punctured, or touching each
other.

• Review proper operation 
of your receiver/amplifier.

If there is low (or no) bass out-
put:

• Make sure the connections
to the left and right “Speaker
Inputs” have the correct 
polarity (+ and –).

• Make sure that the sub-
woofer is plugged into an
active electrical outlet and
switched on.

• Adjust the crossover point.

• Flip the Phase Control switch
to the opposite position.

• If you are using a Dolby
Digital/DTS receiver or 
processor, make sure that the
subwoofer and bass manage-
ment adjustments on the
receiver/processor are set up
correctly.

• Slowly turn the Level Control
clockwise until you begin to
hear the desired amount of
bass.

If you used the line-level
inputs and there is no sound
from the subwoofer:

• Check that the receiver/
amplifier is on and a source is
playing.

• Check that the powered 
subwoofer is plugged into an
active electrical outlet and is
switched on.

• Check all wires and 
connections between the
receiver/amplifier and the sub-
woofer. Make sure all wires
are connected. Make sure
none of the wires are frayed,
cut or punctured, or touching
each other.

• Review proper operation of
your receiver/amplifier.

• Slowly turn the Level 
Control clockwise until you
begin to hear the desired
amount of bass.

• Make sure that you have
configured your receiver/
processor so that the sub-
woofer/LFE output is on.

Phase Control

The Phase Control 

deter-

mines whether the sub-
woofer’s pistonlike action
moves in and out in phase with
the main speakers or opposite
the main speakers. There is no
correct or incorrect setting.
Proper phase adjustment
depends on several variables
such as subwoofer placement
and listener position. Adjust
the Phase switch to maximize

bass output at the listening
position.

Remember, every system, room
and listener is different. There
are no right or wrong settings;
this switch offers the added
flexibility to adjust your sub-
woofer for optimum perfor-
mance for your specific 
listening conditions without
having to move your speakers.
If at some time in the future

you happen to rearrange your
listening room and move your
speakers, you should experi-
ment with the Phase switch in
both positions, and leave it in
the position that maximizes
bass performance.
