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 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  
RIGHT-  
CHANNEL  
SPEAKER  
Since the installation of a subwoofer can be somewhat more complicated  
than installing full-range speakers, it is essential that you read this sec-  
tion 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  
subwoofers volume level too high will result in an overpowering, boomy  
bass. Setting the volume level too low will negate the benefits of  
the subwoofer.

LISTENING  
AREA  
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.  
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 sub-  
woofer 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 lim-  
ited confines of a room, reflections, standing waves and absorptions gen-  
erated within the room will strongly influence the performance of any sub-  
woofer 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.

OPERATION  
Crossover Adjustment  
Power On  
The Crossover Adjustment Control ¢ determines the highest frequency at  
which the subwoofer reproduces sounds. If your main speakers can comfort-  
ably reproduce some low-frequency sounds, set this control to a lower  
frequency setting, between 50Hz and 100Hz.This will concentrate the  
subwoofers efforts on the ultradeep bass sounds required by today’s  
films and music. If you are using smaller bookshelf speakers that do  
not extend to the lower bass frequencies, set the Crossover Adjustment  
control to a higher setting, between 120Hz and 150Hz.  
Plug your subwoofers AC cord into a wall outlet. Do not use the outlets on the  
back of the receiver.  
¡
Initially set the Subwoofer-Level Control to theminposition.  
Turn on your sub by pressing the Power Switch on the rear panel.  
Turn on your entire audio system and start a CD or movie soundtrack at a  
moderate level.  
Auto On/Stand-By  
With the Power Switch in the ON position, the Status LED on  
the back panel will remain lit in red or green to indicate the  
On/Standby mode of the subwoofer.  
NOTE: This control will have no effect if the LFE/Normal Selector is set  
to LFE. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass  
Frequency is set by the processor/receiver. Consult your owners manual to  
learn how to view or change this setting.  
RED = STANDBY (No signal detected,Amp Off)  
GREEN = ON (Signal detected,Amp On)  
MAINTENANCE AND SERVICE  
The subwoofer will automatically enter the Standby mode after approxi-  
mately 10 minutes when no signal is detected from your system.The sub-  
woofer will then power ON instantly when a signal is detected. During

off the Power Switch for extended periods of nonoperation, e.g., when  
you are away on vacation.  
Adjust Gain  
All wiring connections should be inspected and cleaned or remade peri-  
odically.The frequency of maintenance depends on the metals involved in  
the connections, atmospheric conditions, and other factors, but once per  
year is the minimum.  
¡
Turn your Subwoofer-Level Control up to the halfway position. If no  
sound emanates from the subwoofer, check the AC-line cord and input  
cables.Are the connectors on the cables making proper contact? Is the  
AC plug connected to alivereceptacle? Has the Power Switch  
been pressed to theOnposition? Once you have confirmed that the  
subwoofer is active, proceed by playing a CD, record or cassette.  
Use a selection that has ample bass information.  
If a problem occurs, make sure that all connections are properly made  
and clean. If a problem exists in one loudspeaker, reverse the connection  
wires to the left and right system. If the problem remains in the same  
speaker, then the fault is with the loudspeaker. If the problem appears in  
the opposite speaker, the cause is in another component or cable. In the  
event that your subwoofer ever needs service, contact your local Infinity  
dealer or Infinity directly at 1.516.674.4INF or www.infinitysystems.com  
for a service center near you.  
Set the overall volume control of the preamplifier or stereo to a comfort-  
¡
able level.Adjust the Subwoofer-Level Control until you obtain a pleas-  
ing blend of bass. Bass response should not overpower the room but  
rather be adjusted so there is a harmonious blend across the entire musi-  
cal range. Many users have a tendency to set the subwoofer volume too  
loud, adhering to the belief that a subwoofer is there to produce lots of  
bass.This is not entirely true.A subwoofer is there to enhance bass,  
extending the response of the entire system so the bass can be felt as  
well as heard. However, overall balance must be maintained or the music  
will not sound natural.An experienced listener will set the volume of  
the subwoofer so its impact on bass response is always there but never  
obtrusive.  
Phase Control  
£
The Phase Switch determines whether the subwoofer speakers piston-  
like action moves in and out with the main speakers, 0˚, or opposite the  
main speakers, 180˚. Proper phase adjustment depends on several  
variables such as room size, subwoofer placement and listener position.  
Adjust the phase switch to maximize bass output at the listening position.
