Volume
Crossover Frequency
The crossover frequency knob
determines the highest fre-
quency your subwoofer will
reproduce. It allows a seam-
less transition from the
subwoofer to the satellite
speakers. Experiment with this adjustment to find the
crossover frequency that
sounds best with your
speakers. When using the
speaker level connections,
the crossover adjustment will
also limit the low frequencies being sent to your satellite
speakers. This means that
your satellites won’t have
to try and reproduce the
information the subwoofer
is playing.
If you used the high-le vel
(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/
amplifier 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 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 con-
nected. Make sure none of
the wires are frayed, cut, or
punctured.
• Review proper operation of
your receiver/amplifier.
