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 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 ®
mode, 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 speakers, or has
remained in the same channel.
If the problem is in the same
channel, the source of the prob-
lem is most likely with your
receiver or amplifier, and you
should consult the owner’s
manual for that product for fur-
ther information. If the problem
has followed the speaker, con-
sult your dealer for further
assistance or, if that is not pos-
sible, visit www.jbl.com for
further information.
If the sys lays at low vol-
umes but shuts off as vol-
ume is increased:
• Check all wires and connec-
tions between receiver/ampli-
fier 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.
If there is no (or low) bass
output:
• Make sure the polarities
(+ and –) of the left and right
“Speaker Inputs” are con-
nected 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 con-
nections between receiver/
amplifier 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/amplifier
has other surround modes you
may use.
• In Dolby Digital or DTS mode,
make sure your receiver/pro-
cessor 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 responsi-
bility 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 loca-
tion on a wall. (The ceiling is not
a suitable mounting location.)
Drill two pilot holes, appropri-
ately 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 key-
holes, 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.
