Troubleshooting
If there is no sound from any
of the speakers:
• Check that 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 “Balance”
control on your receiver/
amplifier.
• Check all wires and con-
nections 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 all wires and con-
nections between receiver/
amplifier and speakers.
• Make sure all wires are
connected. 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 imped-
ance requirements of your
receiver/amplifier.
If there is no (or low) bass
output:
• Make sure the polarities
(+ and –) of the left and
right “Speaker Inputs” are
connected properly.
