The Northridge Series speaker
models indicated above may be

available through hardware stores,
to properly and safely wall-mount
the speakers. This product is not
intended for ceiling mounting.
Adjustable wall-mounting brackets
are included with models N24II
and N24AWII. Optional, adjustable,
wall-mounting brackets are
available from JBL for model
N26AWII. Contact your dealer,

If there is no sound from
any of the speakers:
•Check that receiver/amplifier is
on and that a source is playing.
•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 connections
between receiver/amplifier
and speakers. Make sure no
wires are touching other wires or
terminals and creating a short
circuit.
•Make sure all wires are
connected. Make sure none of
the speaker wires are frayed, cut
or punctured.
•In Dolby* Digital or DTS®mode,
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 the system plays at low
volumes but shuts off as volume
is increased:
•Check all wires and connections
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 no (or low) bass output:
•Make sure the polarities
(+and–)of the left and right
“Speaker Inputs”are connected
properly.
•Consider adding a powered
subwoofer to your system.
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 configured so that
the center speaker is enabled.
