BALBOA 10 (serv.man5) - JBL Audio User Guide / Operation Manual. Page 3

• Check that receiver/ampli-
fier is on and that a source is
playing.

• Review proper operation of
your receiver/amplifier.

• Check the “Balance” control
on your receiver/amplifier.

• Check all wires and connec-
tions between receiver/ ampli-
fier and speakers.

• Make sure no wires are
touching other wires or 
terminals and creating a short
circuit.

• Make sure all wires are con-
nected. 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 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 working correctly. Turn
everything back on, and deter-
mine 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 prod-
uct 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 
for further information.

• Check all wires and con-
nections 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 impedance
requirements of your receiver/
amplifier.

• Make sure the polarities 
(+ and –) of the left and right
“Speaker Inputs” are 
connected properly.

• If your system includes a
powered subwoofer, make
sure it is connected correctly,
plugged into an active AC out-
let and turned on. See the
owner's guide for your sub-
woofer for more information.

• If your system does not
include a powered subwoofer,
consider adding one for use
with digital “.1” surround for-
mats.

• Check all wires and connec-
tions between receiver/ampli-
fier and speakers. Make sure
all wires are connected. Make
sure none of the speaker
wires are frayed, cut or punc-
tured.

• 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/ampli-
fier 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.

• If you are using both side
surround and back surround
speakers, make sure that your
receiver/processor is config-
ured for 6.1/7.1 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.
