near water — for example, near a bathtub, wash
bowl, kitchen sink, or laundry tub; in a wet basement;
or near a swimming pool; and the like.
ACCESSORIES — Do not place this product on an
unstable cart, stand, tripod, bracket, or table. The
product may fall, causing serious injury to a child or
adult, and serious damage to the product. Use only
with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with
the product. Any mounting of the product should
follow the manufacturer’s instructions, and should
use a mounting accessory recommended by the
manufacturer.
CART — A product and cart combination should be
moved with care. Quick stops, excessive force, and
uneven surfaces may cause the product and cart
combination to overturn.
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.
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.
LOCATION – The appliance should be installed in a
stable location.
NONUSE PERIODS – The power cord of the appliance
should be unplugged from the outlet when left unused for a long period of time.
GROUNDING OR POLARIZATION
•
If this product is equipped with a polarized alternating
current line plug (a plug having one blade wider than
the other), it will fit into the 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.
•
If this product is equipped with a three-wire
grounding type plug, a plug having a third (grounding)
pin, it will only fit into a grounding type power outlet.
This is a safety feature. If you are unable to insert the
plug into the outlet, contact your electrician to
replace your obsolete outlet. Do not defeat the
safety purpose of the grounding type plug.
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.
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.
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 surges.
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.
OVERLOADING — Do not overload wall outlets,
extension cords, or integral convenience receptacles
as this can result in a risk of fire or electric shock.
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 product.
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.
DAMAGE REQUIRING SERVICE - Unplug this product
from the wall outlet and refer servicing to qualified
service personnel under the following conditions:
•
When the power-supply cord or plug is damaged.
•
If liquid has been spilled, or objects have fallen into
the product.
•
If the product has been exposed to rain or water.
•
If the product does not operate normally by 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.
•
If the product has been dropped or damaged in any
way.
•
When the product exhibits a distinct change in
performance — this indicates a need for service.
REPLACEMENT PARTS -- W hen replacement parts
are required, be sure the service technician has used
replacement parts specified by the manufacturer or
have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric
shock, or other hazards.
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.
WALL OR CEILING MOUNTING — The product should
not be mounted to a wall or ceiling.
HEAT — The product should be situated away from heat
sources such as radiators, heat registers, stoves, or
other products (including amplifiers) that produce
heat.

Subwoofer Rear Panel:
1. LIMIT INDICATOR – The LIMIT INDICATOR will blink on occasion when built-in limiter is
active. NOTE: If the indicator glows or starts to blink frequently, you should turn down
the SUBWOOFER LEVEL.
2. SIGNAL INDICATOR – The SIGNAL INDICATOR will glow when when there is a signal received
to the FULL RANGE input.
3. subwoofer gain control – This knob is used to regulate the output level of the subwoofer. Use this to set the balance between the speakers and subwoofers.
4. PROTECT INDICATOR – The PROTECT INDICATOR will begin to glow when the subwoofer goes
into protect mode. Protect mode prevents the subwoofer amplifiers from getting to hot. When the subwoofer goes into protect mode all output will stop. This is to protect the subwoofer and any speakers
connected to the subwoofer.
5. Power led - This L.E.D. will be lit when you switch on the power. 6. HIGH PASS XLR output – These outputs are used to send the incoming signal to a full range

7. PHASE SWITCH – The PHASE SWITCH reverses the polarity of the subwoofer. This switch
depends on the placement of the subwoofer relative to the speakers. Experiment with the
switch and postions of the subwoofer and speakers to find the best sound.
8. Full range XLR Input – These connections are designed to accept a line input signal from
a mixer or other line level device with a balanced output jack. Use a balanced cable when the
signal cable length exceeds 15 feet, this will reduce excessive signal loss. Be sure to connect
only line level input devices such as mixers to these inputs.
9. THRU (FULL RANGE output) – These outputs are used to send the signal from the FULL RANGE
INPUTS to another device.
