INCLUDED
Two satellites for Left/Right front or
surrounds. Wall-mount brackets.
150-180 cm
Surround SpeakersFront Speakers
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 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
listening position, facing for-
ward. The surround speakers
should not call attention to
themselves. Experiment with
their placement until you hear
a diffuse, ambient sound
accompanying the main-
program material heard in the
front speakers.
SCS SATPair 178 speakers are
perfect for bringing music to
additional rooms in your home.
If your receiver or amplifier is
equipped with A/B speaker
switching, simply connect the
pair of speakers to the unused
pair of speaker terminals on
your receiver, following the
directions in the Speaker
Connections section. If you
plan on playing both pairs of
speakers simultaneously,
check with the manufacturer
of your receiver or amplifier to
find out whether that use is
recommended.

MOUNTING OPTIONS
Satellites and Surrounds
On shelves.
Wall-Mounting
The customer is responsible
for proper selection and use
of mounting hardware,
available through hardware
stores, to properly and safely
wall-mount the speakers.
On the wall. Wall brackets
are included.
On optional stands.
Separate and strip the ends of
the speaker wire as shown.
Speakers and electronics
terminals have corresponding
(+) and (–) terminals. Most
manufacturers of speakers
and electronics, including JBL,
use red to denote the (+)
terminal and black for the (–)
terminal.
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 a poor stereo
image.
With the advent of multi-
channel surround-sound
systems, connecting all of the
speakers in your system with
the correct polarity remains
equally important in order to
preserve the proper ambience
and directionality of the
program material.
Stereo
If you are using the JBL SCS
SATPair178 in a stereo system,
connect them to the Left and
Right speaker outputs of your
amplifier/receiver.
Surround
If you are using the JBL SCS
SATPair178 as front or rear
speakers in a surround
system, connect them to the
appropriate front or rear Left
and Right outputs according to
the instructions included with
your surround
amplifier/receiver.
SPEAKER CONNECTIONS
Connection Tips

5
If there is no sound from any of
the speakers:
• Check that receiver/amplifier
is on and a source is playing.
• 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.
If there is no sound coming
from one speaker:
• Check the “Balance” control
on your receiver/amplifier.
• 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.
• In Dolby Digital or DTS®
modes, make sure that the
receiver/processor is
configured so that the
speaker in question is
enabled.
If there is no sound from the
center speaker:
• Check all wires and
connections between
receiver/
amplifier and speaker. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed, cut
or punctured.
• If your receiver/processor is
set in Dolby Pro Logic mode,
make sure the center
speaker is not in phantom
mode.
• If your receiver/processor
is set in Dolby Digital or DTS®
mode, make sure the
receiver/processor is con-
figured so that the center
speaker is enabled.
If the system plays at low
volumes but shuts off as
volume is increased:
• Check all wires and connecti-
ons 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 low (or no) bass
output:
• Make sure the connections
to the left and right “Speaker
Inputs” have the correct
polarity (+ and –).
• If a powered subwoofer is
used, make sure that the
subwoofer is plugged in and
turned on.
• In Dolby Digital or DTS®
modes, make sure your
receiver/processor is
configured so that the
subwoofer and LFE output
are enabled.
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 if 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 disc’s menu.
