stops, excessive force
and uneven surfaces may
cause the product and
cart combination to overturn.
10. Ventilation. Slots and openings in the
cabinet are provided for ventilation and to
ensure reliable operation of the product and
to protect it from overheating, and these
openings must not be blocked or covered. 
The openings should never be blocked by 
placing the product on a bed, sofa, rug or
other similar surface. This product should
not be placed in a built-in installation,
such as a bookcase or rack, unless proper
ventilation is provided or the
manufacturer’s instructions have been
adhered to.
11. 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 product
dealer or local power company. For products
intended to operate from battery power, or
other sources, refer to the operating
12. Grounding or Polarization. This
product may be equipped with a polarized
alternating-current-line plug (a plug having
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 unable
to insert the plug fully into the outlet, try
reversing the plug. If the plug should still
fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat
the safety purpose of the polarized plug.
13. Power-Cord Protection. Power-supply
cords should be routed so that they are not
likely to be walked on or pinched by items
placed upon or against them, paying 
particular attention to cords at plugs, 
convenience receptacles, and the point 
where they exit from the product.
14. Nonuse Periods. The power cord of the
product should be unplugged from the
outlet when left unused for long periods of
15. Outdoor Antenna Grounding. If an
outside antenna or cable system is
connected to the product, be sure the
antenna or cable system is grounded so as
to provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code,
ANSI/NFPA 70, provides information with
regard to proper grounding of the mast and
supporting structure, grounding of the lead-
in wire to an antenna discharge unit, size
of grounding conductors, location of
antenna-discharge unit, connection to
grounding electrodes, and requirements for
the grounding electrode. See Figure A.
16. Lightning. For added protection for
this product during a lightning storm, or
when it is left unattended and unused for
long periods of time, unplug it from the
wall outlet and disconnect the antenna or
cable system. This will prevent damage to
the product due to lightning and power-line
17. Power Lines. An outside antenna
system should not be located in the vicinity
of overhead power lines or other electric
light or power circuits, or where it can fall
into such power lines or circuits. When
installing an outside antenna system,
extreme care should be taken to keep from
touching such power lines or circuits, as
contact with them might be fatal.
18. Overloading. Do not overload wall
outlets, extension cords, or integral
convenience receptacles, as this can result
in a risk of fire or electric shock.
19. Object and Liquid Entry. Never push
objects of any kind into this product
through openings, as they may touch
dangerous voltage points or short-out parts
that could result in a fire or electric shock.
Never spill liquid of any kind on the
20. Servicing. Do not attempt to service
this product yourself, as opening or
removing covers may expose you to
dangerous voltage or other hazards. Refer
all servicing to qualified service personnel.
21. Damage Requiring Service. Unplug
this product from the wall outlet and refer
servicing to qualified service personnel
under the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen onto, or liquid has
been spilled into, the product; or
c. The product has been exposed to rain or
water; or
d. The product does not operate normally
when following the operating instructions.
Adjust only those controls that are covered
by the operating instructions, as an
improper adjustment of other controls may
result in damage and will often require
extensive work by a qualified technician to
restore the product to its normal operation;
e. The product has been dropped or
damaged in any way; or
f. The product exhibits a distinct change in
performance; this indicates a need for
22. Replacement Parts. When replacement
parts are required, be sure the service
technician has used replacement parts
specified by the manufacturer or that have
the same characteristics as the original
part. Unauthorized substitutions may result
in fire, electric shock or other hazards.
23. Safety Check. Upon completion of any
service or repairs to this product, ask the
service technician to perform safety checks
to determine that the product is in proper
operating condition.
24. Wall or Ceiling Mounting. The product
should be mounted to a wall or ceiling only
as recommended by the manufacturer.
25. Heat. The product should be situated
away from heat sources such as radiators,
heat registers, stoves or other products
(including amplifiers) that produce heat.

risk of electric shock to persons.
The exclamation point within an equilateral 
triangle is intended to alert the user to the 
presence of important operating and

Two 20' speaker cables for

Two 15' speaker cables for
connection from subwoofer to
front speakers.
Three 40' speaker cables for
connection from receiver to
left and right rear satellites
and center speaker.
Surround Speakers
5 – 6 ft.
Front Speakers
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 con-
venient 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 screwing the leg in to
angle the speaker up, or
unscrewing the leg slightly to
angle the speaker 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 listening position,
facing forward. 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.
The low-frequency material
reproduced by the
subwoofer is mostly omni-
directional, and this speaker
may be placed in a con-
venient 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 placing the
subwoofer in the listening
position and moving around
the room until the bass
reproduction is best. Place
the subwoofer in that

Separate and strip the 
ends of the speaker wire 
as shown. Speakers and
electronics terminals have
corresponding (+) and (–)
terminals. 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
amplifier. Wiring “out of
phase” results in thin sound,
weak bass and a poor 
stereo image.
With the advent of
multichannel 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.

Connection Tips
Pro Logic
(Non-Digital) – Speaker Level
Use this installation method
for Dolby Pro Logic appli-
cations (not Dolby Digital,
or other digital
processing), where the
receiver/processor does not
have a subwoofer output, or 
a volume-controlled preamp
(line-) level output:
Connect your receiver or
amplifier’s front left and right
speaker 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 terminals on the
back of your front left and
right speakers.  
Connect your receiver or
amplifier’s center, left and
right surround-speaker
terminals to the corre-
sponding terminals on the
back of your center, left and
right surround speakers.
