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 E Series
loudspeakers referred to in
this guide are video-shielded
and can safely be placed near
a television.
CONNECTION TIPS
Speakers and electronics terminals have corresponding
positive (+) and negative (–) terminals. It is important to connect both speakers identically:
positive (+) on the speaker
to positive (+) on the amplifier
and negative (–) on the speaker
to negative (–) 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 as important
as ever in order to preserve the
proper ambience and direction-
ality of the program material.
To use the binding-post speaker
terminals, unscrew the colored
collar until the pass-through
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
banana-type connectors. To
comply with European CE
certification, these holes are
blocked with plastic inserts at
the point of manufacture.To use
banana-type connectors
requires the removal of the
inserts. Do not remove these
inserts if you are using the
product in an area covered by
the European CE certification.

TROUBLESHOOTING
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 has followed the
speakers, or has remained in
the same channel. If the prob-
lem 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 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
whether 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.
NOTICE: Important Safety
Notes
• Proper selection of mounting hardware and installation
of the wall brackets are the
responsibility of the customer.
• This product is not intended
for ceiling mounting.
Two Number 8 round head or
pan head screws should be
used per loudspeaker. The
screw head should be
between 5/16 inch (8mm) and
1/4 inch (6.3mm) in diameter,
and the screw should be at
least 2 inches (50mm) in
length.
When installing screws in any
wall, always use properly
selected wall anchors. Attach
two of the four self-adhesive
rubber pads that came with
the E10 loudspeaker to the
back of the enclosure in the
two bottom corners so that
the cabinet is spaced evenly
from the wall. Select a suitable mounting location on a
wall. (The ceiling is not a suitable mounting location.)
Drill two pilot holes, appropriately sized for the specific
self-tapping screw or wall
anchor that you will be using.
The holes should be 8 inches
(203mm) apart. See Figure 1.
The holes should be 3/4"
(19mm) below where you
want the top of the enclosure
to be positioned. Use a carpenter’s level to ensure that
the holes are even and that
the speaker will mount on the
level.
Install the two screws into
either a wooden wall stud or
anchor, and tighten them until
the back of each screw head
is about 1/8 inch (3mm) from
the wall. See Figure 2. Install
the loudspeaker by slowly
moving the cabinet toward
the screws so that the screw
heads clear the larger circular portion of the two keyholes. Once both screw
heads have entered the keyholes, the loudspeaker should
gently be lowered onto the
screw shafts. Check that the
loudspeaker is firmly locked
onto the screws by gently
pulling the speaker down and
forward.
