Receiver’s Speaker Outputs

Speakers and electronics 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
poor imaging.

To use the binding-post
speaker terminals, unscrew
the colored collar until the
pass-through hole in the cen­ter post is visible. 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.

BI-WIRING

The bi-wire connection
method requires one amplifier
and two sets of speaker wires.
By removing the shorting bars,
connections may be made to
the individual network
using four conductors,

sections

one for

each of the four terminals.

For single-wire connection,
leave the shorting bars in
place and connect only a sin­gle set of speaker wires (two
conductors) to the two upper
terminals.

WALL-MOUNTING

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 roundhead or
panhead screws should be
used for each loudspeaker.
The screwhead should be
between 5/16" (8mm) and 1/4"
(6.3mm) in diameter, and the
screw should be at least 2"
(50mm) in length.

When installing screws in any
wall, it is always preferable to
screw them into a wall stud. If
none is available, it is impor­tant to always use properly
selected wall anchors.

Attach two of the four self­adhesive rubber pads that
came with the 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.
A template is included with
your loudspeaker that indi­cates the proper locations for
the pilot holes. In the event
that the template is missing,
refer to this chart:

Model Distance Between

Pilot Holes

L810 6" (152mm)

L820 8-1/2" (216mm)

LC2 14-1/2" (368mm)

See Figure 1. The holes
should be 2-1/4" (57mm)
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 screwhead
is about 1/8" (3mm) from the
wall. See Figure 2.

Models L810 and L820 may
also be corner-mounted using
the keyholes located on the
bezeled corners. For corner
mounting, fold the mounting
template in half, place the
fold in the corner at the
desired height, and use the
outer holes. If the template is
missing, for corner mounting
drill each pilot hole 7-3/4"
(197mm) from the corner for
model L810, or 9-11/16"
(246mm) from the corner for
model L820. However, if your
corner is not precisely 90
degrees, these measure­ments may not work. In that
case, it is recommended that
you contact a professional
custom installer, who can
determine the correct loca-

tions for the pilot holes. Install
the loudspeaker by slowly
moving the cabinet toward
the screws so that the screw­heads clear the larger circu­lar portion of the two key­holes. Once both screwheads
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.

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

®

modes, 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
problem is in the same chan-

nel, 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, punctured or touching
each other.

• 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
modes, 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’s menu.
