personnel. Servicing is required when the
apparatus has been damaged in any way, such
as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally, or
has been dropped.
Do not use attachments not recommended by 15.
the product manufacturer, as they may cause
hazards.
This product should be operated only from the 16.
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 instructions.
If an outside antenna or cable system is 17.
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.
An outside antenna system should not be located 18.
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.
Do not overload wall outlets, extension cords, or 19.
integral convenience receptacles, as this can
result in a risk of fire or electric shock.
Never push objects of any kind into this product 20.
through openings, as they may touch dangerous
oltage points or short-out parts that could result
in a fire or electric shock. Never spill liquid of
any kind on the product.
The apparatus shall not be exposed to dripping 21.
or splashing, and no objects filled with liquids,
such as vases, shall be placed on the apparatus.
Do not attempt to service this product yourself, 22.
as opening or removing covers may expose you
to dangerous voltage or other hazards. Refer all
servicing to qualified service personnel.
When replacement parts are required, be sure 23.
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.
Upon completion of any service or repairs to this 24.
product, ask the service technician to perform
safety checks to determine that the product is in
proper operating condition.
The product should be mounted to a wall or ceiling 25.
only as recommended by the manufacturer.

INTRODUCTION
Infinity® PS312 Powered Subwoofer
The Infinity® PS312 powered subwoofer continues the longstanding Infinity
commitment to accurate sound reproduction. Our proprietary technology
and engineering resources work together to deliver uncompromised low-
frequency performance in any stereo or multichannel home theater system.
Unpacking the Subwoofer
If you suspect damage from transit, report it immediately to your dealer. Keep
the shipping carton and packing materials for future use.
PLACEMENT
Since installing a subwoofer can be somewhat more complicated than
installing full-range speakers, read this section very carefully prior to
connecting the subwoofer to your system. Should you have questions relating
to your installation, call your dealer or visit www.infinitysystems.com for
assistance.
The performance of the subwoofer is directly related to its placement in the
listening room and how you align the subwoofer with its satellite speakers.
Most audio authorities believe that low frequencies (below 125Hz) are
nondirectional, and, therefore, the location of a subwoofer within any
listening room is not critical; but within the limited confines of a room,
reflections, standing waves and absorptions generated within the room will
strongly influence the performance of any subwoofer system. As a result,
the specific location of the subwoofer becomes important, and we strongly
recommend that you experiment with placement before choosing a final
location.
Placement will depend upon the amount and quality of bass required and upon
your room (for example, whether or not your room permits placement of the
subwoofer near either satellite). Be sure to leave a minimum of 15cm (nearly
six inches) between the wall and the port on the subwoofer.
Setting the volume of the subwoofer in relationship to the left and right
speakers is also of critical importance because it is essential that the
subwoofer integrate smoothly with the entire system. Setting the subwoofer’s
volume level too high will result in overpowering, boomy bass. Setting the
volume level too low will negate the benefits of the subwoofer.
