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.
23. Non-use Periods. The power cord of
the product should be unplugged from the
outlet when left unused for long periods of
time.
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.
Unplug this product from the wall outlet
and refer servicing to qualified service per-
sonnel under the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen, 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 instruc-
tions. 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; 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
performance.
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.
Never spill liquid of any kind on the prod-
uct. The apparatus shall not be exposed to
dripping or splashing and no objects filled
with liquids, such as vases, shall be placed
on the apparatus.
28. Heat. The product should be situated
away from heat sources such as radiators,
heat registers, stoves or other products
(including amplifiers) that produce heat.
Avoid installation in extremely hot or cold
locations, in an area that is exposed to
direct sunlight or near heating equipment.
When positioning the product in its final
location, make certain that it has adequate
ventilation on all sides, as well as on the
top and bottom.
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
cord.

ATX Series loudspeakers are

placements. Best results, how-

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-

mend 1.3 mm wire as minimum,

require thicker wire. If in doubt,

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.

advantage of solid-angle gains.
If you get too much bass, adjust
the ”VOLUME” towards ”MIN”.
The result will be lower distor-
tion and higher reliability. If the
excessive bass is at one or
more discrete frequencies,
then it might be necessary to
consider dealing with room
modes.
• Move both the subwoofer and
the listener.

OPERATION
With LFE Connection
If you are using the LFE input,
the subwoofer's CROSSOVER
control is NOT active, because
this function is controlled by
your surround processor.
When using the LFE input, set
the subwoofer's VOLUME con-
trol to "Max" and calibrate the
subwoofer level along with the
other speakers according to
the set-up instructions in the
owner's manual for your sur-
round receiver/amplifier.

Other Connections
If you are using any other con-
nection method, start with the
subwoofer VOLUME control in
the "9 o'clock" position and the
CROSSOVER in the 12 o'clock
position. To fine-tune the sub-
woofer's volume and crossover
frequency settings, listen to
familiar material with powerful
bass at a typical listening level.
Bass response should not over-
power the room, but instead
contribute to a harmonious
blend across the entire musical
range. Many users have a ten-
dency to set the subwoofer vol-
ume and crossover too high,
believing that a subwoofer is
there to produce lots of boom
and shake the room to make its
presence felt. This is not entire-
ly true. A subwoofer is there to
enhance bass, extending the
response of the entire system
so that bass can be felt as well
as heard.
However, overall balance must
be maintained; otherwise, the
music will not sound natural.
An experienced listener will set
the volume and crossover
of the subwoofer so that its
impact on bass response is
always there, but is never
obtrusive.

Connection Tips
Separate and strip the ends of
the speaker wire as shown.
Speakers and amplifiers/
receivers have corresponding
(+) and (–) terminals. The (+)
lead of the speaker wire is
noted with a stripe. It is impor-
tant to connect all the 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.
