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 con-
venient to set the center
speaker on top of the tele-
vision set, as shown in the
drawing. 

Two of the surround speak-
ers 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 forward. The surround
back speaker (SCS200.6 sys-
tem only) should be placed
on the wall behind the listen-
ing position, facing the cen-
ter channel speaker. The sur-
round speakers should not
call attention to themselves.
Experiment with their place-
ment until you hear a diffuse,
ambient sound accom-
panying the mainprogram
material heard in the front
speakers.

It is neither necessary nor
desirable to tilt the surround
speakers to aim them down
toward the listening area.
They should be aimed
straight ahead to produce
the proper effect.

The low-frequency material
reproduced by the sub-
woofer is mostly omnidirec-
tional, and this speaker may
be placed in a convenient
location in the room. How-
ever, bass reproduction will
be maximized when the sub-
woofer is placed in a corner
along the same wall as the
front speakers. Experiment
with subwoofer placement
by temporarily placing the
subwoofer in the listening
position and moving around
the room until the bass
reproduction is best. Place
the subwoofer in that loca-
tion.

Alternate placement for surround speakers in SCS200.5 
system only.

Surround back speaker is used 
only in SCS200.6 system.

On shelves.

On the wall. 
Wall brackets are included.

On optional stands.

Prepare the speaker wire as
described on page 8. Thread
the two conductors through
the two holes in the stand
bracket. Make sure to pre-
serve the proper polarity 
(+ and – connections) by
threading the positive con-

ductor through the hole on
the left, and the negative
conductor through the hole
on the right looking at the
front of the stand. Push
down on the red speaker ter-
minal and insert the bare end
of the positive wire into the

hole under the red cap.
Release the cap, and tug
gently on the wire to make
sure that the connection is
snug. Follow the same pro-
cedure to connect the nega-
tive wire to its terminal.

+

–

Gently pull the slack out of
the wire and screw the shelf
stand onto the back of the
speaker in two places, as
shown.

Important Safety Note: The
customer is solely responsi-
ble for proper selection of
mounting hardware not
included with the speakers,
and for proper assembly and
installation of the wall-brack-
ets, including but not limited
to the selection of appropri-
ate weight-bearing supports
and proper use of the
bracket. JBL disclaims any
liability for the selection of
mounting hardware and/or
bracket installation. Be sure
to follow these bracket
assembly and installation
instructions carefully. If you
have any questions or
doubts about your ability to
correctly wall-mount the
speakers, consult with your
authorized JBL dealer or
custom installer.

Step 1: Unscrew and remove
the large Molded Nut

™

. If

necessary, use the supplied
Metal Bar

∞

as a lever by

inserting it into one of the
holes in the outer edge of the
Molded Nut

™

.

Step 2: Firmly grasp the Ball
and Shaft

£

and pull it

straight out of the Attach-
ment Plate

¢

. Avoid leaning

it to the side for leverage, as
this may break off a tab.

Step 3: Slide the Molded Nut

™

onto the Ball and Shaft

£

with the threaded open-

ing facing the ball. Thread
the Metal Nut

¡

all the way

onto the Ball and Shaft

£

,

with the Metal Nut’s

¡

“knurled” surface facing
away from the ball. Refer to
the exploded drawing for the
proper orientation of these
three parts.

Step 4: Screw the Ball and
Shaft

£

into the Threaded

§

on the back of the

¶

until it

is fully seated in the
Threaded Insert

§

.

Step 5: Tighten the Metal Nut

¡

using a crescent wrench

(spanner) until it is firmly
seated against the back of
the Satellite Speaker

¶

and

has locked the Ball and

£

and the Satellite

¶

together. Note

that once the Metal Nut

¡

is

fully tightened, it may embed
some marks on the back of
the Satellite Speaker

¶

.

However, these marks will be
covered by the Metal Nut

¡

.

Step 6: Mount the Attach-
ment Plate

¢

into a wood

stud on the wall, using four
#10 pan-head wood screws
at least one inch long (not
supplied) 

•

. Make sure that

all four screws are driven
into the stud and not into dry-
wall.

Step 7: Holding the Satellite
Speaker

¶

with both hands,

reinsert the ball portion of
the Ball and Shaft

£

into the

¢

.

Step 8: Hand-tighten the
Molded Nut

™

while posi-

tioning the speaker for the
desired orientation. The
swiveling ball enables you to
aim the speaker to one side
or the other, or to tilt it up

Separate and strip the ends
of the speaker wire as
shown. The wires supplied
with the system may already
be stripped and tinned for
easy insertion into the
speaker terminals. You may
need to separate the two
conductors further in order
to thread them through the
shelf stand or floor stand
adaptor. Speakers and elec-
tronics terminals have corre-
sponding (+) and (–) termi-
nals. Most manufacturers of
speakers and electronics,
including JBL, use red to
denote the (+) terminal and
black to denote 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 
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.

To connect the supplied
speaker wires to the satellite
and center speaker termi-
nals, press the red or black
plastic cap for the desired
terminal, insert the bare end
of the wire into the hole
below the cap and release
the cap. 

Gently tug on the wire to
make sure that it is fully
inserted.

or down. Although stereo
imaging may be improved 
by aiming the front speakers
toward the listening position,
especially for music selec-
tions, the surround speakers
are intended to provide a 
diffuse, ambient sound that
is best achieved by aiming
the speakers straight out
from the wall. Aiming the
surround speakers toward
the listening position may
ruin the intended effect by
calling too much attention 

to the information in those 
channels.

Step 9: Once the speaker’s
orientation has been final-
ized, insert the Metal Bar

∞

into one of the holes in the
outer edge of the Molded
Nut

™

and tighten the

™

securely.

Keep the Metal Bar

∞

in a

safe place in the event that
you decide to adjust the
speaker’s orientation in the
future.
