Troubleshooting
If there is no sound from
any of the speakers, check
the following:
• Receiver/amplifier is on and
a source is playing.
• Review proper operation of
your receiver/amplifier.
If there is no sound coming
from one speaker, check the
following:
• Check the “Balance” control
on your receiver/amplifier.
• 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.
If the system plays at low
volumes but shuts off as
volume is increased, check
the following:
• Check all wires and connec-
tions between receiver/
amplifier and speakers.
• Make sure all wires are con-
nected. Make sure none of the
speaker wires are frayed, cut
or punctured.
• If more than one pair
of main speakers is being
used, check the minimum-
impedance requirements of
your receiver/amplifier.
If there is low bass output,
check the following:
• Make sure the polarity
(+ and –) of the left and
right “Speaker Inputs” are
connected properly.
