JBL SCS150SI - Manual (Page 8)

If there is no sound from any
of the speakers:
• Check that receiver/amplifier
is on and a source is playing.
• Check that the powered
subwoofer is plugged in, and
its Power switch ¡ is
switched on to the “
• ”
position.
• 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.
• 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.
• In Dolby Digital or DTS
modes, make sure that the
receiver/processor is
configured 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 is in the same place,
i.e., the speaker that was
working previously now has
no sound and the speaker that
was not working now sounds
fine; or whether it has moved,
i.e., the speaker that was not
working still has no sound and
the speaker that was working
is still fine. If the problem is in
the same place, 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 our
Web site at www.jbl.com for
further information.
If there is no sound from the
center speaker:
• Check all wires and
connections between
receiver/amplifier and
speaker. Make sure all wires
are connected. Make sure
none of the speaker wires are
frayed, cut or punctured.
• If your receiver/processor is
set in Dolby Pro Logic mode,
make sure the center speaker
is not in phantom mode.
• If your receiver/processor
is set in Dolby Digital or DTS
mode, make sure the
receiver/processor is con-
figured so that the center
speaker is enabled.
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 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 –).
• Make sure the subwoofer
is plugged into an active
electrical outlet.
• Make sure the powered
subwoofer is plugged in, and
its Power switch ¡ is
switched on to the “
• ”
position.
