Read First!
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings.Install in
accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as
radiators,heat registers,stoves or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized plug has two
blades with one wider than the other.A groundingtype plug has two blades and a third grounding
prong.The wide blade or the third prong are provided
for your safety.If the provided plug does not fit into
your outlet,consult an electrician for replacement
of the obsolete outlet.
10. Protect the power cord from being walked
on or pinched,par ticularly at plugs,convenience
receptacles and the point where they exit from
the apparatus.
11. Only use attachments/accessories specified by
the manufacturer.
12. Use only with the cart,stand,tripod,
bracket or table specified by the manufacturer or sold with the apparatus.
When a cart is used,use caution when moving
the cart/apparatus combination to avoid injury from
tip-over.
13. Unplug this apparatus during lightning storms
or when unused for long periods of time.
14. Refer all servicing to qualified service 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.
15. Do not use attachments not recommended by
the product manufacturer, as they may cause
hazards.
16.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 instructions.
17. 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.
18.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.
19. Do not overload wall outlets,extension cords,or
integral convenience receptacles,as this can result
in a risk of fire or electric shock.
20. 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.
21. 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.
22.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. 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.The product should be mounted to a wall or
ceiling only as recommended by the manufacturer.

INTRODUCTION
Infinity PS-10 and PS-12 Powered Subwoofers
The Infinity PS-10 and PS-12 powered subwoofers continue Infinity’s
longstanding commitment to accurate sound reproduction.Our
proprietary technology and engineering resources work together to
deliver uncompromisedlow-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.
P
LACEMENT
Since the installation of a subwoofer can be somewhat more complicated
than installing full-range speakers,it is essential that you read this section very carefully prior to connecting the subwoofer to your system.
Should you have questions relating to your installation,it is advisable
to call either your dealer or Infinity’s Customer Service Department
for advice.
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.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 an overpowering,boomy
bass.Setting the volume level too low will negate the benefits of
the subwoofer.
Here are several additional facts on installation that may prove useful.
It is generally believed by most audio authorities that low frequencies
(below 125Hz) are nondirectional and,therefore,placement of a subwoofer within any listening room is not critical. While in theory it is true
that the larger wavelengths of extremely low frequencies are basically
nondirectional,the fact is that,when installing a subwoofer 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,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 your room and the amount and quality of bass
required (for example,whether or not your room permits placement of the
subwoofer near either satellite).Be sure to leave a minimum of six inches
between the wall and the port on the subwoofer.
Figure 1.This example shows the subwoofer positioned behind the
right-channel satellite speaker to re-create the actual location of
bass instruments in an orchestra and/or add impact to movie
soundtracks.
