either of the speakers, check
the following:
• Receiver/amplifier is on and a
source is playing.

speakers. Make sure all wires are
connected. Make sure none of
the speaker wires are frayed, cut,

tions between receiver/amplifier,

are connected. Make sure none
of the speaker wires are frayed,
cut, or punctured.
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 –).
If the system plays at low vol-
umes 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 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 impedance require-
ments of your receiver/amplifier.
