SPEAKER PLACEMENT
Proper placement of the
speakers is an important
step in obtaining the most
realistic soundstage
possible. These recommendations are for the
optimum placement of the
loudspeakers. Use these
placement recommendations
as a guide. Slight variations
will not diminish your
listening pleasure.
All of the Northridge Series
loudspeakers referred to in
this guide are video-shielded
and can safely be placed
near a television.

SPEAKER CONNECTIONS
These models are shipped
with four self-adhesive
nonskid pads that are to be
used when the loudspeaker
is intended to be placed on a
smooth-surfaced floor, such
as tile or hardwood. Gently lay
the speaker on its side (not its
front or back) on a soft,
nonabrasive surface. Attach
each pad to the bottom of its
foot in the widest portion of
the recessed area.
DO NOT attach the pads if
the speaker will be placed
on carpeting.
NEVER drag the speaker to
move it, as this will damage
the pads, the feet and/or the
wood cabinet itself. Always
lift the speaker and carry it
to its new location.
CAUTION: Floorstanding
(tower) loudspeakers have
a high center of gravity and
may become unstable and tip
over during earthquakes or if
rocked, tipped or improperly
positioned. If this is a
concern, these speakers
should be anchored to the
wall behind them, using
the same procedures and
hardware customary for
anchoring bookcases and
wall units. Customer is
responsible for proper
installation and proper
selection of hardware.
Without pad With pad
The supplied self-adhesive
felt pads may be attached to
the bottom corners of your
speakers to protect your
furniture.

CONNECTION TIPS
Speakers and electronics
terminals have corresponding (+) and (–) terminals.
It is important to connect both
speakers identically: (+) on
the speaker to (+) on the
amplifier and (–) on the
speaker to (–) on the amplifier.
Wiring “out of phase” results
in thin sound, weak bass and
a poor stereo image. With the
advent of multichannel
surround sound systems,
connecting all of the speakers
in your system with the
correct polarity remains
equally important in order to
preserve the proper ambience
and directionality of the
program material.To use the
binding-post speaker
terminals, unscrew the
colored collar until the passthrough hole in the center
post is visible under the collar.
Insert the bare end of the wire
through this hole; then screw
the collar down until the
connection is tight. The hole
in the center of each collar is
intended for use with bananatype connectors.

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 for
use with digital “.1” surround
formats.
If there is no sound from
the surround speakers:
• 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.
• 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
if your receiver/amplifier has
other surround modes you
may use.
•
In Dolby Digital or DTS mode,
make sure your receiver/
processor is configured so
that the surround speakers
are enabled.
• 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.
