PRO-SW220P 200-Watt-Powered Subwoofer

Your RCA PRO-SW220P 200-Watt

Powered Subwoofer is designed to give

you the best possible low frequency sound

for the ultimate home theater experience.

You will be astonished by the realism it

adds to movie sound effects and the power

it lends to all kinds of music.

The subwoofer combines the power of a

built-in 200-watt RMS amplifier with a

responsive, 12-inch coated paper cone

woofer — all housed in a ported bass-

reflex enclosure to produce tight, floor-

rumbling powerful bass (down to 36 Hz)

that you can feel as well as hear. The

power indicator lets you know when the

subwoofer is operating.

Your subwoofer has an adjustable high cut

filter and high and low level inputs so it is

easily incorporated into existing systems,

or used as an integral part of a subwoofer/

satellite combination.

Its other features include:

Auto On/Off — automatically switches

the PRO-SW220P’s amplifier to standby if

the subwoofer does not receive a signal for

about 11 minutes.

Standby Indicator — power indicator

changes color when the subwoofer is

connected to power but not receiving a

signal.

High-Level Input — lets you connect the

subwoofer to an amplifier’s or receiver’s

speaker outputs.

Note: You need speaker wire (not

supplied) to connect the subwoofer to an

amplifier or receiver’s speaker outputs.

High Level Output — lets you connect

the subwoofer between an amplifier or

receiver (without line out terminals) and

other speakers.

Low Level Input — lets you connect the

subwoofer to an amplifier’s or receiver’s

subwoofer out or pre out jacks. These

inputs automatically sum left and right

channel information.

Note: You need phono cables (not

supplied) to connect the subwoofer to an

amplifier or receiver’s subwoofer out or

pre out jacks.

Volume Control — lets you match the

PRO-SW220P’s output level to your

satellite speakers’ output (if used).

Phase (Polarity) Switch — Inverts the

subwoofer’s output polarity so you can set

it to match the main speakers.

Frequency Hz Control — lets you set the

high frequency cutoff point. Rotated fully

clockwise, the subwoofer cuts high

frequencies over 200 Hz. Rotated fully

counterclockwise, it cuts high frequencies

over 50 Hz.

• Never open the cabinet or remove the

metal control panel, as this might

result in electrical shock or damage to

the unit.

• If your PRO-SW220P needs servicing,

contact your local RadioShack store.

• To prevent electrical shock, do not use

a polarized plug with any extension

cord or outlet unless the blades can be

fully inserted to prevent blade

exposure.

• Unplug the PRO-SW220P power cord

from the electrical outlet if it will not

be used for a long time.

• Only connect this unit to a power

supply of the type described in the

owner’s manual or marked on the

unit.

• Route the power-supply cord so it is

not likely to be walked on or pinched

by items placed upon or against it,

especially at the plug, the outlet, and

the point where the cord exits the

unit.

• Placing the subwoofer on the same

stand or shelf as your turntable can

result in a low-frequency rumble or

acoustic feedback.

Cautions:

• To prevent fire or shock, do not

expose this subwoofer to rain or

moisture.

• Do not place the subwoofer with its

metal plate against the floor.

• Place the subwoofer away from heat

sources such as radiators, stoves, or

other appliances that produce heat.

WARNING: To reduce the risk of fire or

shock hazard, do not expose this product to

rain or moisture.

Cautions:

• To prevent the cabinet from warping

or discoloring, do not place the

subwoofer in a place where it is

exposed to direct sunlight or excessive

humidity.

• Do not place the subwoofer where it

might be knocked over or exposed to

falling objects.

• The metal control panel on the back

of the PRO-SW220P acts as the heat

sink for the subwoofer’s internal

amplifier. Therefore, place the unit at

least 4 inches (10 cm) away from a

wall, and do not let anything come

into contact with this panel.

Where and how you position your

subwoofer greatly affects its bass response.

Adjusting the subwoofer’s volume control

in relation to the left and right speakers

and adjusting the subwoofer’s high cut

filter also affects your speakers’ overall

sound.

Although low frequencies are non-

directional, factors such as room

reflections, standing waves, resonance,

and absorption strongly affect your

subwoofer’s performance. For maximum

bass output, place your subwoofer in a

corner. To reduce output, move it away

from corners and back walls. Even slightly

moving the subwoofer can have a major

effect on bass response.

We recommend that you test the

subwoofer in different locations to

determine where the best balance is

between your satellite speakers (if used)

and subwoofer. We also recommend that

you place the PRO-SW220P at least 4

inches away from the wall, and at least 2–3

feet away from your television or

computer’s disk drive system so the

subwoofer’s magnet will not distort the

colors of your TV picture or erase your

floppy disks.

You can connect your PRO-SW220P to an

amplifier/receiver’s subwoofer out or pre

out jacks or speaker terminals.

Note: You can connect your PRO-

SW220P to your TV if it has variable line

out jacks.

Caution: To avoid any damage to the

subwoofer or amplifier, disconnect power

from your components before making any

connections.

Use this connection if your amplifier/

receiver has jacks labeled SUBWOOFER

OUT or PRE OUT. Do not use the PRE

OUT jacks if they are already connected by

cables or jumpers to your amplifier.

1. Connect the PRO-SW220P’s LOW

LEVEL INPUT jacks to the amplifier/

receiver’s line sub out or pre out jacks

(or TV’s audio line out jacks).

2. Connect your satellite speakers (if

any) to the amplifier’s or receiver’s

output terminals as they would

normally be connected.

Notes:

• On some receivers/amplifiers, the

subwoofer out is a single jack. Use a

single phono cable (not supplied) to

connect the subwoofer jack to the L

input on the PRO-SW220P.

• When connecting to a TV, we

recommend using variable line output

jacks, which will allow the PRO-

SW220P’s volume to change with the

TV’s volume. Refer to your TV owner’s

manual. Also, you can connect to the

TV line out and then adjust the TV

volume up or down. If the subwoofer

volume changes with the TV volume,

then the TV line out is variable.

Connect the amplifier/receiver’s speaker

output terminals to the PRO-SW220P’s

HIGH LEVEL INPUT speaker terminals. Be

sure to connect the terminals in phase,

connecting positive (+) to positive and

negative (–) to negative. Wiring the

subwoofer with + to – causes reduced bass

performance. To match the subwoofer’s

polarity with your system’s polarity and

receive full bass response, slide the

PHASE switch to REV or NOM. Choose

the setting that provides the greatest bass

output.

You can connect your left and right

speakers to your amplifier/receiver (as

shown in “Connecting to Subwoofer Out

or Pre Out Terminals”), or to the PRO-

SW-220P’s HIGH LEVEL OUTPUT

speaker terminals (as shown above).

::: The High Level Output is a pass-

through, and only works when using a

High Level Input.

However, if you use MEGACABLE or

any other high-quality, low-gauge speaker

wire, the terminals will be too small to

accommodate the wires.

You need two pairs of speaker pins

(available at your local RadioShack store)

to make the connection.

Follow these steps to connect the wires to

each terminal using speaker pins.

1. Separate the conductors for a length

of about 2 inches on the end of each

wire. Then strip 1/2 inch of insulation

from the ends of each conductor and

twist the wire ends.

2. Position each wire end between the

open barrel ends of the speaker pin.

3. Using a pair of pliers, crimp the open

barrel ends of the speaker pin to hold

the wire ends in place.

4. Plug the speaker pin into the proper

terminal on the PRO-SW220P.

Once you have made all connections,

follow these steps to adjust the PRO-

SW220P’s volume.

1. Rotate VOLUME CONTROL to MIN.

2. Turn on your amplifier/receiver and

another component (such as a radio,

cassette player, CD player, or

turntable).

3. Begin playing an audio source (such

as a radio) and adjust the amplifier/

speaker’s overall volume to a

comfortable level. Rotate VOLUME

CONTROL on the PRO-SW220P

clockwise a little at a time, until you

achieve a pleasing balance of bass

between the PRO-SW220P and the

main speakers (and satellite speakers,

if used). Bass output should not

overpower the main speakers, but

should blend across the entire musical

range.

Once you have adjusted the PRO-

SW220P’s VOLUME CONTROL, use the

amplifier/receiver’s volume control to

control the speakers’ volume.

FREQUENCY HZ adjusts the level

(between 50 Hz and 200 Hz) at which the

subwoofer begins passing frequencies to

other speakers. This control’s setting

depends on the low frequency capabilities

of your satellite speakers (if used), speaker

placement, and other factors that affect

bass performance.

While playing music, rotate FREQUENCY

HZ clockwise until the music sounds too

bass-heavy. Then rotate it

counterclockwise until the bass sounds

more natural.

If the mid-bass sounds natural but you

want more low bass, rotate FREQUENCY

HZ counterclockwise a little, then rotate

the subwoofer’s VOLUME CONTROL

clockwise by about the same amount. This

increases low-bass output without

affecting the mid-bass output.

To reduce low-bass output without

affecting the mid-bass output, equally

rotate FREQUENCY HZ clockwise and the

subwoofer’s VOLUME CONTROL

counterclockwise.
