* 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 products 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 Manufacturers 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.

GETTING STARTED
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.
Allow at least 6 inches (15cm) of space between any subwoofer driver and a wall or obstruction.

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?
A. “It doesnt 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,
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.
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) 377-7655, Monday through Friday, 9:00 AM through 6:00 PM Eastern time.

VARIABLE LOW PASS CROSSOVER
(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.
VARIABLE PHASE ALIGNMENT
(Fig. 18)–Have someone else turn the knob slowly while you sit in your favorite listening position. Use music with good bass and a deep male vocal. When you hear the best balance of deep bass and the natural lower octaves of the male voice, you have achieved

(Fig. 1b) NEVER LAY THE SUBWOOFER ON THE AMPLIFIER END – THIS WILL DAMAGE THE AMPLIFIER.
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-
fectly. A poor blend will sound unnatur­al; 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.
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.
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 owners 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
FIGURE 1b.
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.
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

the one thats right for you.
AC POWER
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.
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
from a power source.
SUBWOOFER ADJUSTMENTS
SUBWOOFER LEVEL CONTROL–Subwoofer 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.

Large Advantages
You will probably get better blending between main speaker and subwoofer.
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.
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 impact). But if you set your center to Large and you hook up the Subwoofer

to the Subwoofer output jack, the Center bass would not go to the Subwoofer. In 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.
(Fig. 2, previous page)
Now you have it all!
In fact, the PSW1200 has enough inputs to accept every channel of a 5.1 sur­round system. If you want to make sure
you get the bass from every channel through your Subwoofer, simply plug in the preamp output from each channel directly into the PSW1200. No guess­work and no lost bass information.
(Fig. 3)
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 example, assume you want to roll off the

HOOK-UP OPTIONS
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

bottom end of the Rear speakers at 40Hz. Simply use either the Front Line Level or Front Speaker Level in/out sets to do that (assuming they are not already in use). Be creative.
PSW1200 INPUT AND OUTPUT FEATURES AND USE
Front Speaker Level In–Although these are labeled Front, they can be used for any channel. If your equipment does
not haveor if you do not wish to use preamp level outputs to drive your Subwoofer, you can deliver signal via speaker wire
(Fig. 4). The signal will pass
through the Variable Low Pass Crossover.
FRONT SPEAKER LEVEL OUT–
These may be used to route signal to speakers, especially if you want the PSW1200 to filter bass frequencies out of those speakers.

(Speaker Level)–If you want to filter bass out of any speaker, connect the Speaker Level In and Out, and select either 40Hz or 80Hz. Use 40Hz for larg­er speakers, 80Hz for smaller speakers. This feature is useful if you have a stereo or Pro Logic system that has no bass management/speaker setup system and you want to filter bass out of your main speakers. If you do not want to fil­ter out any bass, select Full Range.
(See Fig. 4, previous page)
FRONT LINE IN–Any set of preamp out-
puts may be connected here, but usually Front channel outputs. The signal will pass through the Variable Low Pass Crossover. If you do not have a spare set of pre-outs use a Y connector.

your amplifier to the red (+) terminal on 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
strands. Connect two conductors to the 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 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.
Connect the speaker outputs of your receiver or power amplifier to the Speaker Level In binding posts of the
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

FRONT LINE OUT–Connect these to the
power amp (main) inputs only if you want a high pass filtered signal (selec­table 40Hz or 80Hz) to go into the amplifier
(Fig. 6). The filter cannot be
defeated.
SWITCHABLE HIGH PASS CROSSOVER–
(Line Level)–This selects the filter (crossover) frequency at either 40Hz
or 80Hz at 12dB/octave
(Fig. 6).
REAR LINE IN - Connect rear line level
preamp outputs here (Fig. 7 next page). The signal will pass through the
Variable Low Pass Crossover. Use Y connectors if you need to have these pre–outs connected to a power amplifier or Main In jacks.

CENTER LINE IN–Connect Center line
level preamp output here
(Fig. 7). (There is no need to plug something into both center inputs; one would be redun­dant.) The signal will pass through the Variable Low Pass Crossover. Use a Y connector if you need to have this pre­out connected to a power amplifier or Main In jack.
When this input senses a signal, it auto­matically boosts the Subwoofer’s output
by 3dB. This feature is useful because 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.

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 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 orbass management function of your
electronics. Read the owner’s manual of your electronics to learn how to select
this setting.
FIGURE 8.
HOW TO TELL IF YOUR SUBWOOFER OUTPUT JACK IS FILTERED OR NOT
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 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.
