The Phase Control determines
whether the subwoofer
speaker’s piston-like action
moves in and out with the
main speakers, 0°, or opposite
the main speakers, 180°. There
is no correct or incorrect set-
ting. 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.

Phase Control
Remember, every system,
room and listener is different.
There are no right or wrong
settings; any setting you
choose will result in excellent
performance. Should you
decide to fine-tune your
system for optimum
performance, be patient and
trust your ears. It will be
worth the effort involved to
fully “tweak” your system.
Troubleshooting
If you used the high-level
(speaker) inputs and there is
no sound from any of the
speakers, check the
following:
• Receiver/amplifier is on
and a source is playing.
• Powered subwoofer is
plugged in.
• Check all wires and connec-
tions between receiver/ampli-
fier and speakers. Make sure
all wires are connected. Make
sure none of the speaker wires
are frayed, cut or punctured.
• Review proper operation
of your receiver/amplifier.
If there is low bass output,
check the following:
• 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.
• Powered subwoofer is
plugged in.
• Adjust the crossover point.
• If you are using a Dolby
Digital/DTS receiver or
processor, make sure that the
subwoofer adjustments on
the receiver/processor are
set up correctly.
If you used the line-level
inputs and there is no sound
from the subwoofer, check
the following:
• Receiver/amplifier is on and
a source is playing.
• Powered subwoofer is
plugged in.
• Check all wires and con-
nections between receiver/
amplifier and subwoofer. Make
sure all wires are connected.
Make sure none of the wires
are frayed, cut or punctured.
• Review proper operation of
your receiver/amplifier.
