IMPORTANT: Make sure all
equipment is turned off before
making any connections.
For speaker connections, use
a high-quality speaker wire
with polarity coding. The side
of the wire with a ridge or other
coding is usually considered
positive (+) polarity.
NOTE: If desired, consult
your local JBL dealer about
speaker wire and connection
options.
The speakers have coded
terminals that accept a variety
of wire connectors. The most
common connection is shown
in Figure 1.
To ensure proper polarity,
connect each + terminal on
the back of the amplifier or
receiver to the respective +
(red) terminal on each speaker,
as shown in Figure 2. Connect
the – (black) terminals in a
similar way. See the owner’
s
guides that were included
with your amplifier, receiver
and television to confirm
connection procedures.
IMPORTANT: Do not reverse
polarities (i.e., + to
–
or
–
to +)
when making connections.
Doing so will cause poor
imaging and diminished bass
response

FINAL
ADJUSTMENTS
Check the speakers for
playback, first by setting the
system volume control to a
minimum level, and then by
applying power to your audio
system. Play a favorite music
or video segment and increase
the system volume control to a
comfortable level.
NOTE: You should hear
balanced audio reproduction
across the entire frequency
spectrum. If not, check all
wiring connections or consult
the authorized JBL dealer from
whom you purchased the
system for more help.
Both the amount of bass you
hear and the stereo-image
quality will be affected by a
number of different factors,
including the room’s size and
shape, the construction
materials used to build the
room, the listener’s position
relative to the speakers, and
the position of the speakers in
the room.
Listen to a variety of music
selections and note the bass
level. If there is too much bass,
move the speakers away from
nearby walls. Conversely, if you
place the speakers closer to
the walls, there will be more
bass output.
Nearby reflecting surfaces can
adversely affect stereo-imaging
quality. If this happens, try
angling the speakers slightly
inward toward the listening
position until the optimum
effect is achieved.
CARE OF YOUR
SPEAKER SYSTEM
Each Project Array enclosure
has a finish that does not
require any routine main-
tenance. When needed, use
a soft cloth to remove any
fingerprints or dust from
the enclosure or grille.
NOTE: Do not use any cleaning
products or polishes on the
cabinet or grille.
WIRING THE SYSTEM
Separate and strip the ends of
the speaker wire (not supplied)
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.
The (+) lead of the speaker
wire is sometimes noted with
a stripe or other demarcation.
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.
