Speaker Outputs
RIGHT LEFT
Speakers and electronics terminals have corresponding (+) and
(–) terminals. It is important to connect both speakers identi-
cally: (+) on the speaker to (+) on the amplifier and (–) on the
speaker to (–) on the amplifier. Wiring “out of phase” results in
thin sound, weak bass and a poor stereo image.
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 imped-
ance requirements of your
receiver/amplifier.
If there is low bass output,
check the following:
• Make sure the polarities
(+ and –) of the left and
right “Speaker Inputs” are
connected properly.
If there is no sound from
the center speaker, check
the following:
• Make sure that your receiver’s
Center Channel Mode is in the
”normal“ or ”wide“ position. If
it is in the ”phantom“ position,
the center speaker will not play.
• Check all connections
between processor/amplifier
and the center speaker.
