* About Power Ratings
When making comparisons between
product specifications it helps to understand 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 field” basis for comparison. Make
sure the basis for the power rating is
clearly stated before comparing it to
another product’s specification.
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 Power” rating 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 output 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 Average” ratings to have
very different Dynamic Power performance.
However, loudspeaker efficiency is by
far the most important factor in determining how loud your system will play.
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
Manufacturer’s Association are currently
engaged in an effort to set standards for
specifying the actual acoustic output of
self-powered speakers. If we are successful, 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 Port™ patented bass port for
deep bass with low distortion.
• High-current 350 watt power amplifier.
• 7 low level input channels—left front,
right front, center, subwoofer, LFE, left
rear and right rear—to allow connection of every channel’s output to the
subwoofer. There is never a question
whether or not all the bass on your
recording is getting to your PSW1200
subwoofer!
• 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
program material
• Auto movie detect and bass boost.
(When the center channel input senses
a signal, it automatically boosts the
overall subwoofer level by 3dB)
• Auto on/off circuit that automatically
turns your Subwoofer on when it senses
a program signal. When no signal is
present, the amplifier turns itself off
within 15 minutes
• Unfiltered LFE/Subwoofer input for
use with low pass filtered subwoofer
output jacks
• Speaker and line level inputs and outputs
• Switchable high-pass filters. When
passed through the PSW1200, main
channel signals may be high pass
filtered at either 40Hz or 80Hz from
both line or speaker level outputs
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 phenomenon 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 placement to find the location that yields the
deepest, tightest bass in your favorite
listening position.

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
speaker’s finish. Remove grilles and
gently vacuum the dust.
Q. “WHY DOES MY SYSTEM HUM?”
Zantech (1-800-843-5465) or Channel
Plus (1-800-99-5225).
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.
If none of our suggestions work for you,
call our customer service number shown
below.
A. “It doesn’t know the words.”
This is what passes for humor in the
audio business. Here is the real answer:
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 electrical 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 television). You can obtain this device from
some audio dealers, Radio Shack stores,
TECHNICAL ASSISTANCE
OR SERVICE
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 “auto” position. 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.
Our cheerful customer service representatives are happy to answer your
questions and provide fast, friendly
service. In North America call (800)

(Fig. 18)–This control adjusts the
frequency range over which the
Subwoofer operates. This control only
affects signals that are sent through the
Front, Center and Rear line level “In”
jacks and the Speaker Level Inputs.
It has no effect on signals fed into the
LFE/Subwoofer input. When using
smaller main speakers, the upper range
of the control will probably yield the
best results. With larger speakers, the
lower end of the control range will probably sound best, but always let your
ear be the final judge. After setting
subwoofer levels, you may want to

experiment with the crossover frequency setting. Turning the knob up will add
more “warmth” to the bass and lower
midrange, possibly at the expense of
bass “tightness” and midrange clarity.
Turning the knob down will make
the bass and lower midrange sound
“thinner.” Experiment and set this
control to taste.

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.
WHAT IS BASS MANAGEMENT AND HOW
DO I USE IT?
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.
CONNECTING THE SUBWOOFER TO
THE SYSTEM—GENERAL
The PSW1200 was designed to allow
you to get the maximum bass performance from your stereo or home theater
system, regardless of the type of equipment you have. Due to the broad range
of equipment available, and the versatility 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.
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 “blend” per-
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 channel’s bass to another
speaker—generally 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.
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
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 electronics’ owner’s 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:
5
BASS MANAGEMENT/SPEAKER
SETUP SETTINGS
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.
Normal–(center speaker only) Bass frequencies 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 Jack–In 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 “tuning” tools, you shouldn’t
use this output unless it is unfiltered.
See page 13 for information on filtered
and un-filtered outputs.
THX Variation–In 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®
Dolby Labs mandates that Dolby Digitalprocessor equipped electronics must
offer “all channels small” and “all channels large” options, 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.
6
Large–When you select a speaker as
“Large” that speaker will be sent a fullrange signal: all the sounds that are on
that channel will go to that speaker.
Small–Most often Center and Surround
channels are small, bass-limited speakers 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 subwoofer output jack is “Off,” the bass
should go to the front Left and Right
channel outputs. If you select Front
speakers as “Small” and Subwoofer
“Off” you are going to lose a lot of bass.
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 “beefy” bookshelf
speaker like a Polk RT55 “small” or
“large”? Is it good or bad to have such
a speaker play bass?
“Small” Advantages
• 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

SUBWOOFER ADJUSTMENTS
The PSW1200 has a built-in power
amplifier and must be plugged into a
standard household 110-120V AC power
source in order to operate.
SUBWOOFER LEVEL
CONTROL– Subwoofer
The power switch has three positions:
“On,” “Off” and “Auto” (Fig. 16). In the
“Auto” position, the amplifier will automatically turn on, and the green pilot
light on the front of the subwoofer will
illuminate, as soon as the speaker senses a signal coming from your electronics. The amplifier and the green pilot
light will turn off approximately 15 minutes after input signal ceases. In the
“On” position, the power amplifier will
operate and the green pilot light will
illuminate until the switch is set to “Off”
position or the AC cord is disconnected
level is adjustable
via the knob on the front of the subwoofer under the logo pod (Fig. 17).
Play a piece of music that has an average amount of bass
content. Adjust by ear using a variety of
CDs and video sources. Adjust for deep,
powerful bass, avoiding “boominess.”

• You will probably get better blending

• The bass “attack” or “tightness” may
be better
• Imaging may be more even, seamless
and natural
HOW THE PSW1200 CAN HELP
If your system has no bass management/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-
ers as “Large” or “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.
Here’s 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
impact). But if you set your center to
“Large” and you hook up the Subwoofer

this case, you can select your Center as
“Large” and hook up the center channel
output directly to the Center channel
input of the PSW1200.

The Front, Rear, and Center, etc., labels
on the PSW1200’s inputs and outputs
are just there for convenience. There is
no reason why you cannot use a given
set of jacks for another channel. For

The PSW1200 offers a wide range of hook-up and use options. Each option has advantages and potential downsides. The option that
is best for you depends on your electronics, Your main speakers, and your personal taste. The hook-up method you use will have
a large impact on the “blending” between your main Front speakers and the Subwoofer. Read all the options before selecting

your speaker, and the wire from the
black (-) terminal of the amplifier to the
black (-) terminal on your speaker. Most
wire has some indication (such as colorcoding, ribbing, or writing) on one of the
two conductors to help maintain consistency. If your Subwoofer does not seem
to produce much bass, it is most likely
that one of the speaker wires is connected backwards. Double-check all
connections for correct polarity.
Strip 1/2” of insulation from each of the
two conductors on both ends to expose
the bare wire. Twist the exposed wire of
each conductor to form two un-frayed

receiver or amp (refer to the owner’s
manual supplied with your electronics
for assistance with proper hookup).
Connect the two conductors on the other
end of the wire to the speaker terminals. Repeat for the other channel.
To connect wire to the binding post,
unscrew the plastic hex nut on the binding post and insert the bare wire into
the hole near the base of the binding
post (Fig. 11). Do not insert the insulated part of the wire into the hole, as
this will not give you a good connection.
Twist the hex nut back down the binding
post until it firmly meets the wire. Do
not over-tighten.

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.
Connect the speaker outputs of your
receiver or power amplifier to the
Speaker Level In binding posts of the
14
PSW1200. You may connect your main
speakers either to the Speaker Level
Out binding posts of the PSW1200
(Fig. 9) or directly to your receiver or
amp (Fig. 10 next page).
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 terminals is marked red (+) and the other
black (-). Make certain that you connect
the wire from the red (+) terminal of

Connect rear line level

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.

HOW TO TELL IF YOUR SUBWOOFER
OUTPUT JACK IS FILTERED OR NOT
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 unfiltered, connect the subwoofer output
jack to any unused Line Level In jack
(Fig. 8). In either case, with Dolby
Digital systems, select Subwoofer as
“on” or “yes” in the “speaker set up” or
“bass management” function of your
electronics. Read the owner’s manual of
your electronics to learn how to select
LFE/SUBWOOFER IN -
Use the “speaker set-up” or “bass
management” function of your
Dolby Digital processor to select
Subwoofer as “on” or “yes.” Connect
the Subwoofer output jack to the
“LFE/Subwoofer” input 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 filtered. If all you can hear is bass, and
the vocals are barely or not at all
audible, your Subwoofer input jack
is filtered.
