IMPORTANT SAFETY
INSTRUCTIONS
READ BEFORE OPERATING EQUIPMENT
These products were designed and manufactured to meet strict quality
and safety standards. There are, however, some installation and
operation precautions which you should be particularly aware of.
1 . Read Instructions—All the safety and operating instructions should
be read before the system is operated.
2. Retain Instructions—The safety and operating instructions
should be retained for future reference.
3. Heed Warnings—All warnings on the appliances and in the
operating instructions should be adhered to.
4. Follow Instructions—All operating and use instructions
should be followed.
5. Cleaning—Unplug the appliances from wall outlets before
cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth
for cleaning. 6. Attachments—Do not use attachments not recommended
by the product manufacturer as they may cause hazards.
7. Water and Moisture—Do not use these appliances near water-
for example, near a bath tub, wash bowi, kitchen sink, or laundry tub, in a
wet basement, or near a swimming pool, and the like.
8. Accessories—Do not place these appliances on an unstable
cart, stand, tripod, bracket, or table. The audio/video products may fall,
causing serious injury to a child or adult, and serious damage to the
products. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the appliances. Any
mounting of the appliances should follow the manufacturer's instructions,
and should use mounting accessories recommended by the manufacturer.
9. Ventilation—Slots and openings in the cabinet are provided
for ventilation and to ensure reliable operation of the appliances and to
protect them from overheating, and these openings must not be blocked or
covered. The openings should never be blocked by placing the products
on a bed, sofa, rug, or other similar surface. These products should never
be placed near or over a radiator or heat register. These products should
not be placed in a built-in installation such as a bookcase or rack unless
proper ventilation is provided or the manufacturer's instructions have been
adhered to. 10. Power Sources—These products should be operated only
from the type of power source indicated on the marking labels. If you are
not sure of the type of power supply to your home, consult your appliance
dealer or local power company. For video products intended to operate
from battery power, or other sources, refer to the operating instructions.
1 1 . Grounding or Polarization—These products are equipped with
polarized alternating-current line plugs (plugs having one blade wider than
the other).
This plug will fit into the power outlet only one way. This is a safety
feature. If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, contact your
electrician to replace your
obsolete outlet. Do not
defeat the safety purpose of
the polarized plug.
12. Power-Cord
Protection—Power-
supply cords should be
routed so that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the appliances.
13. Lightning—For added protection for these audio/video products
during a lightning storm, or when they are leftun-attended and unused
for long periods of time, unplug them from the wall outlet and
disconnect the antenna or cable system. This will prevent damage to
the products due to lightning and power-line surges.
14. Servicing—Do not attempt to service these products yourself as
opening or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel. 1 5.
Damage Requiring Service—Unplug these products from wall outlets
and refer servicing to qualified service personnel under the following
conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the products
c. If the products have been exposed to rain or water.
d. If the products do not operate normally by following the operating
instructions. Adjust only those controls that are covered by the operating
instructions as an improper adjustment of other controls may result in
damage and will often require extensive work by a qualified technician
to restore the product to its normal operation.
e. If the product has been dropped or the cabinet has been damaged.
f. When the product exhibits a distinct change in performance-this
indicates a need for service.
1 6. Replacement Parts—When replacement parts are required, be sure
the service technician has used replacement parts specified by the
manufacturer or have the same characteristics as the original part
Unauthorized substitutions may result in fire, electric shock or other

For accessories information visit www.polkaudio.com 3
hazards. 1 7. Safety Check—Upon completion of any service or repairs to
these products, ask the service technician to perform safety checks to
determine that the products are in proper operating condition.
G ETTI N G STARTE D
Please inspect your loudspeaker carefully. Notify your Polk dealer if you notice any damage or missing items. Keep the carton and packing
material. It will do the best job of protecting your speaker if it needs to be transported.
Note to PSW505 owners only: Your PSW505 system includes a detachable power cord that's packaged seperately from the cabinet. Insert
female end into recepticle on amplifier plate and insert polarized AC plug into wall outlet(or power strip) as per safety instructions on inside
cover of this manual.
P LACE M E NT ( F I G U RE S 1 , 2 & 3)
Your PSW Series subwoofer offers many placement options—in an entertainment center, behind furniture, or next to a sofa or chair. It
can be placed anywhere in the room, but you will get the best performance from it when it is on the same side of the room as the front
speakers. Placing it near a wall or in a corner will increase bass loudness. Allow at least 6 inches (15cm) of space between the subwoofer
driver and a wall or obstruction (Figure 1). The subwoofer should onlybe placed on its base (Figure 2). It maylie on its side, but NEVER
LAY THE SUBWOOFER ON THE AMPLIFIER END-THIS WILL DAMAGE THE AMPLIFIER (Figure 3).
Your powered subwoofer is magnetically shielded for placement near video monitors. Allow at least 18" (45cm) of space between your subwoofer and any
television. If you notice video distortion or discoloration, immediately move the subwoofer away from the TV and call Polk Audio Customer Service 80()-
377-7655 (US & Can), 410-358-3600, 9am-6pm EST, Monday through Friday, or email: [e-mail].

CO N N E CTI N G THE SUBWOOFER T O THE SYSTEM—G E NERAL
If you elect to use the speaker level inputs, use two-conductor 16 gauge or thicker speaker wires. See your Polk dealer for
wire recommendations.
Note that one of the speaker input terminals on the rear of the speaker is marked red (+) and the other black (O. Make certain that
you connect the wire fromthe red (+) terminal of 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 color coding, ribbing,
or writing) on one of the two conductors to help maintain consistency. If your subwoofer doesn't 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" (12mm) 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.
U S I N G PU S H -TAB TE RM I NALS - PSW3 03 (FIGU RE 4)
Push the plastic tab of one connector to open up the hole. Insert the bare wire into the hole, and release the plastic tab. Repeat this
step for the other terminal.
Make sure that none of the bare wire ends (left & right) touch. Such contact could result in an electrical short and cause your receiver or
amplifier to turn off or malfunction.
US I N G B I N D I N G POST CO N N E CTI ON S - PSW404 AND
PSW505(Fl GURE 5)
Unscrew binding post hex nuts several turns. Make sure that none of the bare wire endstouch. Such contact could result in an electrical short
and cause your amplifier or receiver to turn off or malfunction.

RECOMMENDED H O O K-UP METHOD FOR "SATELLITE" SYSTE MS
SUCH AS PO LK RM S E R I ES SPEAK
ERS (F I G U RE S 6 & 7)
Connect the left and right front speaker outputs of your receiver or amplifier to the speaker level inputs of the powered subwoofer using
speaker wire.
Then, connect the left and right front satellite speakers using speaker wire from the speaker level outputs from the powered
subwoofer. If it is more convenient, parallel wire the subwoofer and front satellites from your receiver (Figure 7), Connect the
Center Channel Speaker directly to the center channel output from your receiver.
Connect the Rear Surround Satellites directly to the rear or surround channel outputs from your receiver.
and
R ECE IVER SET-UP 1 BASS MANAGEMENT
All surround receivers allow you to "customize" their performance depending on the size of your speakers. Refer to the owner's manual of
your receiver or surround processor to learn how this is done. To get the best performance from small "satellite/subwoofer" type systems,
use the following settings with the above hook-up method: Front speakers set to "large"
Center speaker - set to "normal" or "small"
Surround speakers - set to "small"
Subwoofer - set to "OFF" or "none." (We know. Doesn't make sense, right? Your system obviously has a subwoofer. But really truly, this
is the correct setting for the recommended hook-up method. By setting the front left and right speakers to "Large" and routing them through
the subwoofer as instructed above, you deliver a full range signal to the subwoofer's low pass filter. The low pass filter directs low
frequencies and to the subwoofer. Full range signal is passed to the front speakers, for perfect sub/sat blending.)
HOOK-UP METHOD #2 (FIGURE 8)
This method can be used with electronics that include a "SUB OUT" feature (Figure 8). It is not recommended for use with compact sub/sat
systems. Connect a single RCA cable from the "SUB OUT" of your electronics to the LFE input of the subwoofer. This input bypasses the
subwoofer's variable low pass filter and relies on the filter built into your electronics. If your "SUB OUT" is an unfiltered signal (check your
owner's manual), use either left or right "Line Level Input," to use the low pass crossover in the subwoofer. When using method #2, it is
necessary to adjust the settings of your electronics as follows: Front speakers = large or small depending on their output capabilities;
Subwoofer = "ON."
HOOK-UP METHOD #3 (FIGURE 9)
This method is for use with electronics featuring "PRE OUT" jacks—and maybe used as a secondary hook up method for use with compact
satellite speakers such as Polk RM Series. Connect the left and right preamp output from your electronics to the left and right LINE LEVEL
input of the subwoofer. This may require use of RCA "Y" cables (not supplied) to hookup both the subwoofer and your power amplifier.
When using method #3, it is necessary to adjust the settings on your preamp/processor as follows: Front speakers = LARGE; Subwoofer =
"OFF" or "NO."
AC POWER CON N ECTI O N AND AUTO ON/OFF ( FI G U RE S 1 0, 1 1 & 1
2)
These PSW series subwoofers feature auto on/off circuitry, marked "auto" on the power switch, that automatically turns your subwoofer on
when it senses a program signal. Vhen no signal is present, the circuit turns the subwoofer off after a few minutes. If you are concerned about
the brief delaybetween when the music starts and when the subwoofer turns on, simply leave your subwoofer in the "on" position. When the
power switch is set to "OFF" (PSW303 or PSW404) or "STANDBY" (PSW505) it consumes a low amount of power. If this is a concern,
you may want to leave your PSW system unplugged during extended periods of non use, such as during a vacation.
Note (PSW505 owners only): Your PSW505 has a detachable power cord.
SUBWOOFER ADJ USTMENTS (FI G URES 1 0, 1 1 & 1 2)
Your Powered Subwoofer offers a range of setting options. We recommend the following settings as starting points, but the settings that
are best for you depend upon your speaker placement, electronics and personal taste. After you've become familiar with what the settings

do, experiment with alternate options to find the method that works best for your system setup. You'll find an informative article on
"Subwoofer Positioning and Adjustment" in the set up section at: http://www.polkaudio.com/home/faqad/
" MAK I N G ADJ USTMENTS " OR " FI N E TU N I N G " (F I G U RE S 1
0, 1 1 & 1 2 )
•For RM System adjustments please refer to their owners manuals.
•Volume—Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without "boominess."
•Low Pass—This control adjusts the frequencyrange over which the subwoofer operates. 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. If male vocals sound "thin," turn this control up until the voice sounds rich but not
boomy. If male vocals sound too "thick" or "chesty," turn this control down until the voice sounds natural. NOTE: This control does
not operate when the subwoofer is connected with Method #2 (LFE Input).
•Phase Switch—Have someone switch between the two settings 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 natural lower octaves of the male voice, you have
achieved optimum phase tuning.
Q: " Why does my system h u m ? "
A : "Because it do esn 't know the words. "
This is what passes for humor in the audio business. Here's the real answer: If you have any electrical (50/60Hz) hum in your system you're
going to hear it clearly as soon as 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 attaches to your coaxial cable where it plugs into your VCR (or television). They're simple to
install and usually solve the hum problem. Find 75 ohm ground loop isolators at your audio dealer, Radio Shack stores, or online at
http://shop.polkaudio.com.
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.
