GETTING STARTED

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.

PLACEMENT (FIGURES 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 only be
placed on its base

(Figure 2). It may lie 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 800-377-7655
(US & Can), 410-358-3600, 9am-6pm EST, Monday through Friday, or email: [e-mail].

CONNECTING THE SUBWOOFER TO THE SYSTEM—GENERAL

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 (-). Make certain that you connect the wire

from the 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.

USING PUSH-TAB TERMINALS – PSW303 (FIGURE 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.

USING BINDING POST CONNECTIONS – PSW404 AND PSW505(FIGURE 5)

Unscrew binding post hex nuts several turns. Make sure that none of the bare wire ends touch. Such contact could result in an electrical short and cause your
amplifier or receiver to turn off or malfunction.

RECOMMENDED HOOK-UP METHOD FOR “SATELLITE” SYSTEMS
SUCH AS POLK RM SERIES SPEAKERS
(FIGURES 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.

RECEIVER SET

All surround receivers allow you to “customize” their performance depending on the size of your speakers. Refer to the owner’
surround processor to learn how this is done. T

-UP / BASS MANAGEMENT

s manual of your receiver or

o 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.” (W

e 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 may be 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 CONNECTION AND AUTO ON/OFF (FIGURES 10, 11 & 12)

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. When no signal is present, the circuit turns the subwoofer off after a few minutes. If you are concerned about the brief delay between 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 ADJUSTMENTS (FIGURES 10, 11 & 12)

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:

“MAKING ADJUSTMENTS” OR “FINE TUNING” (FIGURES 10, 11 & 12)

• For RM System adjustments please refer to their owners manuals.
olume—Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without “boominess.”

• V

• Low Pass—This control adjusts the frequency range 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.
