damage immediately by calling your dealer
and/or the shipping company that deliv-
ered it.
2. Connections: Whenever changing, con-
necting or disconnecting signal or power
cables etc., always turn off all equipment.
This prevents transients from entering the
equipment and prevents electrical energy
from reaching you. Keep all connections
out of the reach of children. Before moving
the unit, be certain to disconnect any
interconnection cords with other compo-
nents, and make certain that you discon-
nect any powered units from the AC outlet.

amplifier-clipping, which causes damage
not covered by guarantee.
Active (Powered) Products:
19. 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 Make certain that the proper
space (more than 10cm) is provided both
above and below the unit for ventilation. If
the amplifier will be installed in a cabinet
or other enclosed area, make certain that
there is sufficient air movement within the
cabinet, with means provided for hot air to
exit and for cool air to be brought in.
Do not obstruct the ventilation slots on the
top of the unit or place objects directly
over them. Remember, power amplifiers
generate heat, and the heatsink fins and
ventilation slots that form part of the cabi-
net are specially designed to remove this
heat. Placing other electronic equipment
CAUTION: To prevent electric shock,
 do not remove the grounding plug 
on the power cord, or use any plug 
or extension cord that does not have 
a grounding plug provided. 
Make certain that the 
AC outlet is properly grounded. 
Do not use an adapter plug 
with this product.
The lightning flash with arrowhead

near these heat-dissipation systems may
possibly affect the long term reliability of
both your amplifier and the objects placed
above it.
Do not place CDs, record jackets, owner’s
manuals or other paper on top of or
beneath the unit or in between products
containing amplifiers in a stack. This will
block the air flow, causing degraded per-
formance and a possible fire hazard.
20. 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 sup-
ply to your home, consult your product
dealer or local power company. For prod-
ucts intended to operate from battery
power, or other sources, refer to the oper-
ating instructions.
21. Grounding or Polarization. This product
may be equipped with a polarized alternat-
ing-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.
22. 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 parti-
cular attention to cords at plugs, con-
venience receptacles, and the point where
they exit from the product. To avoid safety
hazards, use only the power cord supplied
with your unit. If a replacement cord is
used, make certain that it is of a similar
gauge. We do not recommend using exten-
sion cords with this product. As with all
electrical devices, do not run power cords
under rugs or carpets or place heavy
objects on power cords. Damaged power
cords should be replaced immediately, by a
qualified service technician, with cords
meeting factory specifications. When dis-
connecting the power cord from an AC
outlet, always pull the plug; never pull the
23. Non-use Periods. The power cord of
the product should be unplugged from the
outlet when left unused for long periods of
24. Lightning. For added protection for this
product during a lightning storm, or when it
is left unattended and unused for long peri-
ods of time, unplug it from the wall outlet
and disconnect the antenna or cable sys-
tem. This will prevent damage to the prod-
uct due to lightning and power-line surges.
25. Overloading. Do not overload wall out-
lets, extension cords, or integral conven-
ience receptacles, as this can result in a
risk of fire or electric shock.
26. Damage Requiring Service. Do not
attempt to service this product yourself, as
opening or removing covers may expose
you to dangerous voltage or other hazards.

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 operate
normally or exhibits a marked change in
27. Object and Liquid Entry. Never push
objects of any kind into this product
through openings, as they may touch dan-
gerous voltage points or short-out parts
that could result in a fire or electric shock.

Center Channel Speaker
ATX Series loudspeakers are
designed to give very good per-
formance in a wide variety of
placements. Best results, how-
ever, will be obtained when the
speakers are placed on a
strong and sturdy stand at a lit-
tle distance from walls and cor-
ners. Placement in corners will
increase the amount of bass,
which can result in a “heavy”
or “boomy” sound. If such
placement is unavoidable, it is
recommended that you use the
tone control on the amplifier or
receiver to reduce the bass. 
For good stereo imaging, we
suggest that you begin with the
two loudspeakers about 
2.5 metres from your listening
position and at a similar 
distance apart. 
Every room is different and we
strongly recommend that you
experiment a little from this
basic starting position in order
to get the most pleasant
To connect the loudspeaker
system to your amplifier or re-
ceiver use two-conductor insu-
lated wire. For each channel,
the red terminal on the loud-
speaker should be connected
to the red or (+) loudspeaker
terminal on the amplifier or
receiver and the black terminal
on the loudspeaker should be
connected to black or (-) termi-
nal on the amplifier. We recom-
mend 1.3 mm wire as minimum,
but longer wire runs might
require thicker wire. If in doubt,
please consult your authorized
JBL dealer who can recom-
mend suitable cables.
