MODEL: E30
The supplied self-adhesive
rubber feet may be attached to
the bottom corners of your
speakers to protect your
furniture.
MODELS: E60,
E80, E90
These models feature four rub-
ber feet which enable them to
be placed on a smooth-surfaced
floor, such as tile or hardwood.
Four metal spikes are supplied
for use when the speaker is to
be placed on a carpeted sur-
face, to decouple the speaker
from the floor and prevent
unwanted damping.
To insert the spikes, gently lay
the speaker on its side (not its
front or back) on a soft,
nonabrasive surface. Each
spike screws into the threaded
insert in the center of each rub-
ber foot. Make sure all four
spikes are screwed in
completely for stability.
NEVER
drag the speaker to
move it, as this will damage the
spikes, 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 cen-
ter 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 cus-
tomary for anchoring bookcases
and wall units. The customer is
responsible for proper installa-
tion and proper selection of
hardware.
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 touch-
ing 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
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 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
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 connec-
tions 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 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
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/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.
