10. Power Sources. This product should
be operated only from the type of power
source indicated on the marking label. If
you are not sure of the type of power
supply to your home, consult your prod-
uct dealer or local power company. For
products intended to operate from bat-
tery power, or other sources, refer to the
operating instructions.
11. Grounding or Polarization. This prod-
uct may be equipped with a polarized
alternating-current line plug (a plug hav-
ing one blade wider than the other). This
plug will fit into the power outlet only one
way. This is a safety feature. If you are

and will often require extensive work
by a qualified technician to restore the
product to its normal operation; or
e. The product has been dropped, or the
enclosure damaged; or
f. The product does not appear to oper-
ate normally or exhibits a marked
change in performance.
19. Attachments. Do not use attachments

Subwoofer
Surround Speakers
1.52 – 1.83m
(5 – 6 ft.)
Front Speakers
0 –0.61m (0 –2 ft.)
The front speakers should be
placed the same distance from
each other as they are from
the listening position. They
should be placed at about the
same height from the floor as
the listeners’ ears will be, or
they may be angled toward the
listeners.
The center-channel speaker
should be placed slightly
behind the front left and right
speakers, and no more than
two feet above or below the
tweeters of the left and right
speakers. It is often conve-
nient to set the center speaker
on top of the television set, as
shown in the drawing. Use the
supplied support leg to aim it
toward the listener by screw-
ing the leg in to angle the
speaker up, or unscrewing the
leg slightly to angle the speak-
er down.
The two surround speakers
should be placed slightly
behind the listening position
and, ideally, should face each
other and be at a level higher
than the listeners’ ears. If that
is not possible, they may be
placed on a wall behind the lis-
tening position, facing forward.
The surround speakers should
not call attention to them-
selves. Experiment with their
placement until you hear a dif-
fuse, ambient sound accompa-
nying the main-program mater-
ial heard in the front speakers.
The low-frequency material
reproduced by the subwoofer
is mostly omnidirectional, and
this speaker may be placed in
a convenient location in the
room. However, the best repro-
duction of bass will be heard
when the subwoofer is placed
in a corner along the same
wall as the front speakers.
Experiment with subwoofer
placement by temporarily plac-
ing the subwoofer in the listen-
ing position and moving
around the room until the bass
reproduction is best. Place the
subwoofer in that location.

MOUNTING OPTIONS
Satellites and Surrounds
On shelves.
Wall-Mounting
Attach plate to wall. The
brackets should be placed,
if possible, so that the
screws will fasten into a
wooden wall stud. If that is
not possible, use properly
selected wall anchors.
The customer is respon-
sible for proper selection
and use of mounting hard-
ware, available through
hardware stores, to prop-
erly and safely wall-mount
the speakers.
On the wall. Wall brackets
are included.
Slide speaker onto support.
On optional stands (FS300).
Place speaker and support
on wall plate.

Separate and strip the ends
of the speaker wire as
shown. Speakers and elec-
tronics terminals have corre-
sponding (+) and (–) termi-
nals. Most manu-facturers of
speakers and electronics,
including JBL, use red to
denote the (+) terminal and
black for the (–) terminal.
The (+) lead of the speaker
wire is noted with a stripe. It
is important to connect both
speakers identically: (+) on
the speaker to (+) on the
amplifier and (–) on the
speaker to (–) on the ampli-
fier. Wiring “out of phase”
results in thin sound, weak
bass and a poor stereo
image.
With the advent of multi-
channel surround-sound sys-
tems, connecting all of the
speakers in your system with
the correct polarity remains
equally important in order to
preserve the proper ambi-
ence and directionality of the
program material.

Dolby* Pro Logic* (Non-Digital) – Speaker Level
Use this installation method for
Dolby Pro Logic appli-cations
(not Dolby Digital, DTS®or
other digital processing),
where the receiver/processor
does not have a subwoofer out-
put, or a volume-controlled pre-
amp (line-) level output:
Connect your receiver or ampli-
fier’s front left and right speak-
er terminals to the left and right
terminals on the subwoofer
that are marked “High Level
In.” Connect the left and right
terminals on the subwoofer
that are marked “High Level
Out” to the cor-responding ter-
minals on the back of your front
left and right speakers.
Connect your receiver or ampli-
fier’s center, left and right sur-
round-speaker terminals to the
corre-sponding terminals on
the back of your center, left and
right surround speakers.

Use this installation method
for Dolby Pro Logic appli-
cations (not Dolby Digital, DTS
or other digital processing),
where the receiver/processor
is equipped with a subwoofer
output, or a volume-controlled
preamp (line-) level output:
Use RCA-type patch cords
to connect the line-level sub-
woofer outputs on your receiv-
er or amplifier to the line-level
inputs on the subwoofer.
IMPORTANT: Do not use the
LFE input on the subwoofer
with Dolby Pro Logic proces-
sors. Note: If your receiver or
amplifier only has one sub-
woofer output jack, then you
will need to use a Y-connector
(not included). Plug the male
end of the Y-connector into
your receiver or amplifier’s
subwoofer output jack, and
connect each of the two
female ends to separate RCA-
type patch cords. Finally, plug
the RCA-type patch cords into
the line-level inputs on the
subwoofer.
Connect each speaker to the
corresponding speaker termi-
nals on your receiver or ampli-
fier.
Use this installation method for
Dolby Digital, DTS or other dig-
ital surround processors:
Use the line-level input jack
marked “LFE” for the Low-
Frequency Effects channel.
Connect this jack to the LFE
output or subwoofer output
on your receiver or amplifier.
Connect each speaker to the
corresponding speaker termi-
nals on your receiver or ampli-
fier.
Make sure that you have con-
figured your surround-sound
processor for “Subwoofer
On.” The front left, front right,
center and rear speakers
should all be set to “Small.”

subwoofer. The SCS135 sub-
woofer will automatically turn
itself on or go into standby
(sleep) mode when left in the
standby mode (“Auto/On”
switch ™ in the “Auto” posi-
tion). When your receiver or
amplifier is off, or is not send-
ing program material to the
subwoofer, the subwoofer will
be in standby mode. When the
sub-woofer senses an audio
signal, it will automatically turn
itself on. If the subwoofer does
not sense a signal after
approximately twenty minutes,
it will automatically go into
standby mode.
When the “Auto/On” switch
™
is switched to the “On” posi-
tion, the subwoofer will remain
on, whether or not program
material is playing.
If you will be away from home
for an extended period of time,
or if the subwoofer will not be
used, switch the Master Power
switch ¡ to the Off position.
