If there is no sound from any
of the speakers:
• Check that receiver/amplifier
is on and a source is playing.
• 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,
or touching each other.
• 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,
or touching each other.
• In Dolby
®
Digital or DTS
®
modes, make sure that the
receiver/processor is con-
figured so that the speaker
in question is enabled.
• Turn off all electronics
and switch the speaker in
question with one of the
other speakers that is
working correctly. Turn
everything back on, and
determine whether the
problem has followed the
speaker, or has remained
in the same channel. If the
problem is in the same
channel, the source of the
problem is most likely with
your receiver or amplifier,
and you should consult the
owner’s manual for that
product for further informa-
tion. If the problem has
followed the speaker, con-
sult your dealer for further
assistance or, if that is not
possible, visit www.jbl.com.
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,
or touching each other.
• If more than one pair of
main speakers is being
used, check the minimum
impedance requirements
of your receiver/amplifier.
If there is low (or no) bass
output:
• Make sure the connections
to the left and right “Speaker
Inputs” have the correct
polarity (+ and –).
• If your system includes a
subwoofer, check its oper-
ation and the configuration
of your receiver or proces-
sor. If your system has no
subwoofer, consider adding
a powered subwoofer.
If there is no sound from
the surround speakers:
• 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,
or touching each other.
• Review proper operation of
your receiver/amplifier and
its surround sound features.
• Make sure the movie or
TV show you are watching
is recorded in a surround
sound mode. If it is not,
check to see whether your
receiver/amplifier has other
surround modes you may use.
• In Dolby Digital or DTS
modes, make sure your
receiver/processor is con-
figured so that the surround
speakers are enabled. When
five satellites are in use,
remember to configure your
receiver or processor for
6.1-channel operation,
and when six satellites
are in use, configure your
receiver or processor for
7.1-channel operation.
• Review the operation of
your DVD player and the
jacket of your DVD to make
sure that the DVD features
the desired Dolby Digital
or DTS mode, and that you
have properly selected that
mode using both the DVD
player’s menu and the DVD
disc’s menu.
