* About Power Ratings  
SPECIFICATIONS  
PSW1200  
When making comparisons between  
product specifications it helps to under-  
stand what they mean, particularly with  
amplifier power ratings. The Federal Trade  
Commission has recently issued new  
regulations regarding the power ratings  
of all amplifiers including self-powered  
speakers. Polk Audio supports this effort  
to standardize power testing methods in  
order to provide consumers with a level  
playing fieldbasis for comparison. Make  
sure the basis for the power rating is  
clearly stated before comparing it to  
another products specification.

Inputs  
Speaker and line level  
The FTC rating is based on the continuous  
power output of the amplifier. However,  
music and movies are not continuous but  
are mainly composed of short bursts of  
sound. For this reason we also supply a  
Dynamic Powerrating which measures  
the ability of the amplifier to produce power  
in short bursts similar to those found in  
music and movies. In our experience an  
amplifier with higher Dynamic Power out-  
put will play louder under most conditions  
regardless of the continuous power rating.  
Dynamic Power is typically greater than  
continuous average power although it is not  
uncommon for two amplifiers with identical  
FTC Continuous Averageratings to have  
very different Dynamic Power performance.

However, loudspeaker efficiency is by  
far the most important factor in determin-  
ing how loud your system will play.  
Line Level Outputs:  
Switchable 40Hz or  
80Hz, 12db/octave  
Loudspeaker efficiency is usually given as  
the amount of sound produced by 1 watt at  
a distance of 1 meter. A medium efficiency  
loudspeaker rating would be around 87 dB  
from 1 watt at 1 meter. A highly efficient  
loudspeaker might be 90 dB. Each 3dB  
increase in efficiency doubles the sound  
output for a given power input. So a 100  
watt, 90 dB self-powered speaker and a  
200 watt 87 dB unit would produce the  
same sound output. For this reason we  
also specify the loudspeaker efficiency  
and calculated maximum sound output.

Polk Audio and the Consumer Electronics  
Manufacturers Association are currently  
engaged in an effort to set standards for  
specifying the actual acoustic output of  
self-powered speakers. If we are success-  
ful, consumers will be able to use these  
ratings to make more meaningful product  
comparisons and better purchasing  
decisions in the future.

FEATURES:  
GETTING STARTED  
Two 12-inch direct radiating smooth  
response subwoofer drivers.  
Power Portpatented bass port for  
deep bass with low distortion.  
High-current 350 watt power amplifier.  
7 low level input channelsleft front,  
right front, center, subwoofer, LFE, left  
rear and right rearto allow connec-  
tion of every channels output to the  
subwoofer. There is never a question  
whether or not all the bass on your  
recording is getting to your PSW1200  
subwoofer!  
Please inspect your subwoofer and its  
drivers carefully. Notify your Polk dealer  
if you notice any damage or missing  
items. Keep the carton and packing  
material. They will do the best job of  
protecting your PSW1200 if it needs  
to be transported.  
PLACEMENT  
The Polk PSW1200 subwoofer may be  
placed anywhere in the room, but for  
the greatest possible bass output, place  
the subwoofer near a corner of the  
room. Due to a room acoustics phenom-  
enon called standing waves,bass  
response may be uneven throughout a  
room. In some areas of the room, the  
bass will be very loud, in others very  
weak. Experiment with subwoofer place-  
ment to find the location that yields the  
deepest, tightest bass in your favorite  
listening position.  
Front panel volume control  
Variable low-pass crossover and  
variable phase controls allow you to  
optimize performance to match your  
audio system, room acoustics, and

Ground loops and hum can also be the  
result of faulty electrical wiring in your  
home. Consult a licensed electrician to  
evaluate and, if necessary, repair the  
AC wiring in your home. Light dimmers  
also tend to introduce noise into audio  
systems. Remove them.  
MAINTAINING THE APPEARANCE  
OF YOUR PSW1200  
Your new speaker cabinet is finished in  
woodgrain vinyl that can be dusted or  
cleaned with a moist soft cloth. Avoid  
harsh detergents and cleaning fluids,  
they can permanently damage your  
speakers finish. Remove grilles and  
gently vacuum the dust.  
If none of our suggestions work for you,  
call our customer service number shown  
below.  
Q. WHY DOES MY SYSTEM HUM?”  
A. It doesnt know the words.”  
TECHNICAL ASSISTANCE  
OR SERVICE  
This is what passes for humor in the  
audio business. Here is the real answer:  
If, after following the hook-up  
directions, you have trouble, please  
double-check all wire connections.  
If the problem is that you are not getting  
enough bass, make sure the AC cord is  
connected to a live AC power source and  
that the power switch is set to the on”  
or autoposition. Should you isolate  
the problem to the speaker, contact the  
authorized Polk Audio dealer where you  
made your purchase. Authorized Polk  
Audio dealers are the best source for  
advice and assistance.  
If you have any electrical 60Hz hum  
in your system, you are more likely  
to hear it once you hook up your  
Subwoofer. Most hum problems are  
caused by ground loops. That is, the  
electrical grounds of the components in  
your system are not at the same electri-  
cal potential. A very common ground  
loop source is cable TV. Disconnect the  
coaxial cable from your TV and/or VCR.  
If the hum goes away, the cable is the  
ground loop villain. In that case, you  
need a 75-ohm ground loop isolator.  
This device is about the size of a pen  
and is attached to your coaxial cable  
where it plugs into your VCR (or televi-  
sion). You can obtain this device from  
some audio dealers, Radio Shack stores,  
Our cheerful customer service repre-  
sentatives are happy to answer your  
questions and provide fast, friendly  
service. In North America call (800)

fectly. A poor blend will sound unnatur-  
al; you will be aware that the main and  
subwoofer speakers are separate units.  
In a well-blended system, the subwoofer  
will not call attention to itself; you will  
simply hear at lot more deep, tight,  
exciting bass. Experiment with alternate  
hook-up methods to find the one that  
works best for you.  
FIGURE 1b.  
WHAT IS BASS MANAGEMENT AND HOW  
DO I USE IT?  
Bass management involves moving bass  
signals from one speaker to another. For  
example, if you have a speaker that is  
not well suited to reproducing loud deep  
bass, bass management allows you to  
move that channels bass to another  
speakergenerally to the subwoofer.  
The PSW1200 has some built-in bass  
management features for those systems  
that have no bass management facility  
at all, or for those whose facilities are  
inadequate for your needs.  
The PSW1200 is not magnetically  
shielded and should not be placed  
close to a television set. If you see  
any color distortion in your TV, move  
the subwoofer a few inches farther  
from the set.  
Stereo receivers and preamps never  
have bass management facilities.  
If you have a stereo-only system, go  
immediately to page 9. Dolby Pro Logic®  
receivers and processors usually have  
minimal bass management facilities.  
Dolby Digital® processors always have  
bass management features but  
CONNECTING THE SUBWOOFER TO  
THE SYSTEMGENERAL  
The PSW1200 was designed to allow  
you to get the maximum bass perfor-  
mance from your stereo or home theater  
system, regardless of the type of equip-  
ment you have. Due to the broad range  
of equipment available, and the versatil-  
ity of the PSW1200, we are not able to  
describe every possible hook up method.  
Start by understanding the issues and  
the capabilities of the PSW1200. From  
there, you should be able to determine  
the hook up method that is perfect  
for you.  
the capabilities and operation may  
vary from model to model.  
The bass management system function  
in your receiver or processor is usually  
accessed through an on-screen display  
and may be called Speaker Set-Up.”  
Some units use switches on the front  
and/or rear panels. Read your electron-  
icsowners manual to learn how to  
access your bass management/speaker  
setup features. Here is a list of the  
terms and choices you will find, and  
how they operate:  
WHAT ARE THE GOALS?  
The first goal is to make sure that all  
the bass information on the recording  
gets to your speakers. Second, that the  
bass gets to the speakers that are best  
suited to reproduce it. And third that all  
the speakers in the system blendper-

BASS MANAGEMENT/SPEAKER  
SETUP SETTINGS  
LargeWhen you select a speaker as  
Largethat speaker will be sent a full-  
range signal: all the sounds that are on  
that channel will go to that speaker.  
DOLBY PRO LOGIC  
Wide(center speaker only) The center  
speaker is sent a full-range signal: all  
the sounds that are on that channel will  
go to the center speaker.  
SmallMost often Center and Surround  
channels are small, bass-limited speak-  
ers and are set to Small.When you  
select a speaker as Small,frequencies  
below a certain point (usually 80Hz) are  
taken out and sent somewhere else.  
Where does that bass go? It will go to  
the subwoofer output jack if that jack is  
turned On(see below). If the sub-  
woofer output jack is Off,the bass  
should go to the front Left and Right  
channel outputs. If you select Front  
speakers as Smalland Subwoofer  
Offyou are going to lose a lot of bass.  
Normal(center speaker only) Bass fre-  
quencies below 100Hz are filtered out of  
the center channel and sent to the Front  
and Subwoofer outputs.  
Phantom(center speaker only) Not part  
of the bass management/speaker setup  
system at all. This simply sends all the  
center information into the front speakers.  
Subwoofer Output JackIn Pro Logic  
units this output is nothing more than  
summed left and right front channels  
with a low pass (lets only bass through)  
filter, usually fixed at 80Hz. Because a  
fixed filter negates the Variable Low  
Pass Crossover function, one of your  
main bass tuningtools, you shouldnt  
use this output unless it is unfiltered.  
See page 13 for information on filtered  
and un-filtered outputs.  
Subwoofer Yes (ON) / No (OFF)–  
This determines whether the subwoofer  
output jack is fed signal. If it is Off,”  
any bass redirected from other channels  
and the LFE-channel bass should go to  
the Front L&R outputs.  
SMALL AND LARGE DECISION MAKING  
Most of the time this choice is easy to  
make. A very small bookshelf or on-wall  
speaker should always be selected as  
Small. A main speaker with built-in  
powered subwoofers should be selected  
as Large. Sometimes this choice is not  
so clear cut. Is a beefybookshelf  
speaker like a Polk RT55 smallor  
large? Is it good or bad to have such  
a speaker play bass?  
THX VariationIn THX certified Pro Logic  
receivers and processors, the front main  
speakers can also be selected as WIDE  
(LARGE) or NORMAL (SMALL). When  
selected as NORMAL (SMALL), the bass  
is filtered out of the front  
channels and sent to the subwoofer  
output jack.  
DOLBY DIGITAL AND DTS®  
SmallAdvantages  
Dolby Labs mandates that Dolby Digital-  
processor equipped electronics must  
offer all channels smalland all chan-  
nels largeoptions, but beyond that  
there are no standards. Most units allow  
any combination of Large / Small”  
choices for Front, Center and Surround  
channels, but not all do. In such cases,  
the PSW1200 allows you to overcome  
that limitation.  
By rolling off the bottom end (taking  
out the bass) of a speaker, it can play  
a lot louder, with less distortion. If you  
play your system very loud, and your  
speakers are not full-range behemoths,  
this is the right choice for you  
The midrange will be clearer and  
better defined

LargeAdvantages–  
ers as Largeor Small, you can use  
the high pass filters on the PSW1200 to  
roll off their response at 40 Hz instead  
of relying on the fixed 80 Hz filter in  
your receiver or processor.  
You will probably get better blending  
between main speaker and subwoofer.  
The bass attackor tightnessmay  
be better  
Imaging may be more even, seamless  
and natural  
Heres another example: you have a  
large full-range Center speaker like the  
Polk CS1000p. You want it to play  
Center bass frequencies (for better  
imaging) and you also want to send  
those Center bass frequencies to the  
Subwoofer (to get better system  
HOW THE PSW1200 CAN HELP  
If your system has no bass manage-  
ment/speaker setup feature or if it does  
not meet your needs, the PSW1200 can  
help. For example, if you are torn  
between setting your front main speak-  
impact). But if you set your center to  
Largeand you hook up the Subwoofer

SPEAKER CONNECTIONS  
Speaker level hook up is often the most  
convenient method and may yield the  
best results, especially if the subwoofer  
is placed far from your electronics.  
Speaker wires are a lot less susceptible  
to picking up hum and noise than are  
long RCA cables.  
Use 2-conductor 16 gauge or thicker  
speaker wires. See your Polk dealer for  
wire recommendations. Note that one of  
each set of Speaker Level Input termi-  
nals is marked red (+) and the other  
black (-). Make certain that you connect  
the wire from the red (+) terminal of

most people like a little more bass for  
movies than music. When you are  
listening in stereo, the Center channel  
speaker is off so the boost does not  
kick in.As soon as you put on a movie  
in surround sound, the Center speaker  
turns on and the 3dB bass boost  
engages. If you do not want to use this  
feature, use an available input instead  
of one of these.  
When this input senses a signal, it auto-  
matically boosts the Subwoofers output

HOW TO TELL IF YOUR SUBWOOFER  
OUTPUT JACK IS FILTERED OR NOT  
Use the speaker set-upor bass  
managementfunction of your  
Dolby Digital processor to select  
Subwoofer as onor yes.Connect  
the Subwoofer output jack to the  
LFE/Subwooferinput of the  
PSW1200. Disconnect the other  
speakers in the system so that all  
you can hear is the Subwoofer. Play  
music or a movie with vocal content.  
If you can hear and understand the  
words, your output jack is not fil-  
tered. If all you can hear is bass, and  
the vocals are barely or not at all  
audible, your Subwoofer input jack  
is filtered.  
LFE/SUBWOOFER IN - Use this input only  
if you have a Dolby Digital system and  
know your Subwoofer output jack is low  
pass filtered (Fig. 7 previous page).  
If the Subwoofer output jack is unfil-  
tered, connect the subwoofer output  
jack to any unused Line Level In jack  
(Fig. 8). In either case, with Dolby  
Digital systems, select Subwoofer as  
onor yesin the speaker set upor  
bass managementfunction of your  
electronics. Read the owners manual of  
your electronics to learn how to select  
this setting.
