Troubleshooting - JBL SCS SAT 300 Owner's Manual

TROUBLESHOOTING

If there is no sound from any
of the speakers:
• Check that receiver/ampli-
fier 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 config-
ured 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 work-
ing correctly. Turn everything
back on, and determine
whether the problem has fol-
lowed the speaker, or has
remained in the same chan-
nel. 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 information. If the
problem has followed the
speaker, consult 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 imped-
ance 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 opera-
tion and the configuration of
your receiver or processor.
If your system has no sub-
woofer, 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 config-
ured 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.
