PRO SW-200P 200-Watt Powered Subwoofer

Your Optimus PRO SW-200P 200

Watt Powered Subwoofer is designed

to give you the best possible low fre-

quency sound for the ultimate home

theater experience. You will be aston-

ished 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 infrared remote control lets you

turn the subwoofer on and off and reg-

ulate its volume without interrupting

your listening. The LED power indica-

tor lets you see at a glance when the

subwoofer is operating.

Your subwoofer has an adjustable

high cut filter and high and low level in-

puts so it is easy incorporation into ex-

isting systems or it as an integral part

of a subwoofer/satellite combination.

It also has these features:

Auto On/Off — Automatically switch-

es the PRO SW-200P’s amplifier to

standby if the subwoofer does not re-

ceive a signal for 8–11 minutes.

Power Indicator — The red LED on

VOLUME lights when the amplifier re-

ceives an audio signal, and turns off

when the amplifier goes into standby

mode.

Hi

g

h Level Input — Lets you connect

the PRO SW-200P to an amplifier’s or

receiver’s speaker outputs.

Low Level Input — Lets you connect

the PRO SW-200P to an amplifier’s or

receiver’s line out jacks. These inputs

automatically sum left and right chan-

nel information.

Volume Control — Lets you match

the PRO SW-200P’s output level to

your satellite speakers’ output (if

used). Rotate it clockwise to increase,

or counterclockwise to decrease, the

subwoofer’s output.

Frequency Hz — Controls the high

frequency cutoff point. Rotated fully

clockwise, it cuts high frequencies

over 200 Hz. Rotated fully counter-

clockwise, it cuts high frequencies

over 50 Hz.

Remote Control — Lets you control

the PRO SW-200P’s volume from up

to 30 feet away. Just point the remote

control at the subwoofer’s infrared

lens.

Note: If you lose your remote control,

the subwoofer will still operate. Simply

unplug the PRO SW-200P for 10 sec-

onds, then plug it back in. Then use

VOLUME CONTROL to control the vol-

ume. You can order a replacement re-

mote control through your local

RadioShack store.

This symbol is intended to alert you

to the presence of uninsulated dan-

gerous voltage within the product’s

enclosure that might be of sufficient

magnitude to constitute a risk of

electric shock. Do not open the prod-

uct’s case.

This symbol is intended to inform

you that important operating and

maintenance instructions are includ-

ed in the literature accompanying

this product.

SAFETY INSTRUCTIONS

• 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 SW-200P needs ser-

vicing, contact your local Ra-

dioShack store.

• To prevent electrical shock, do not

use this polarized plug with an

extension cord receptacle or other

outlet unless the blades can be

fully inserted to prevent blade

exposure.

• Unplug the PRO SW-200P’s

power cord from the electrical out-

let if it will be left unused for a long

time.

• Only connect this unit to a power

supply of the type described in the

operating instructions 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 plugs, con-

venience receptacles, and the

point where it exits from the unit.

• Placing the subwoofer on the

same stand or shelf as your turnta-

ble can result in low frequency

rumble or acoustic feedback.

CAUTION

RISK OF ELECTRIC SHOCK.

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.

CHOOSING A LOCATION

Cautions:

• To prevent the cabinet from warp-

ing 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 SW-200P 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 sub-

woofer greatly affects its bass re-

sponse. 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-di-

rectional, factors such as room reflec-

tions, standing waves, resonance and

absorption strongly affect your sub-

woofer’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 re-

sponse.

We recommend that you test the sub-

woofer in different locations to deter-

mine where the best balance is

between your satellite speakers (if

used) and subwoofer. We also recom-

mend that you place the PRO SW-

200P 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.

CONNECTING TO AN

AMPLIFIER

You can connect your PRO SW-200P

to an amplifier/receiver’s line out or

speaker terminals.

Note: You can connect your PRO SW-

200P to your television if your televi-

sion has line out jacks.

Caution: To avoid any damage to the

subwoofer or amplifier, disconnect

power from your components before

making any connections.

Connecting to Line Out

Terminals

Your amplifier/receiver’s line out jacks

might be labeled either REC OUT or

PRE OUT.

Note: We recommend you connect the

subwoofer to an amplifier or receiver

that has at least two sets of line out

jacks. Connecting the subwoofer to an

amplifier or receiver with only one set

of line out jacks might result in no

sound from the satellite speakers. If

your amplifier has only one set of line

out jacks, follow the instructions under

“Connecting to Speaker Terminals” in-

stead.

1. Connect the PRO SW-200P’s

LOW LEVEL INPUT jacks to the

amplifier/receiver’s (or TV’s) line

out jacks. Be sure to connect the

jacks in phase, with left to left and

right to right.

2. Connect your satellite speakers (if

any) to the amplifier/receiver’s out-

put terminals as they would nor-

mally be connected.

Note: If you connect your PRO SW-

200P to your amplifier/receiver’s line

out terminals and your amplifier/re-

ceiver has a line out selector switch,

be sure to switch it to the correct

source.

Connecting to Speaker

Terminals

Connect the amplifier/receiver’s

speaker output terminals to the PRO

SW-200P’s HIGH LEVEL INPUT termi-

nals. Be sure to connect the terminals

in phase, connecting positive (+) to

positive and negative (–) to negative.

Wiring the PRO SW-200P with + to –

causes reduces bass performance.

Connecting Speakers

You can connect your left and right

speakers to your amplifier/receiver (as

shown in the illustration on Page 4), or

to the PRO SW-200P’s HIGH LEVEL

INPUT speaker terminals (as shown

above). The connection for the PRO

SW-200P remains the same.

If you use MEGACABLE or any other

high quality, low gauge speaker wire,

the terminals will be too small to ac-

commodate the wires from both the

left (or right) speaker and the PRO

SW-200P. You need two pairs of

Speaker Pins (RadioShack Unlimited

No. 10458503) to make the connec-

tion. Follow these steps to connect the

wires to each terminal using Speaker

Pins.

1. Twist together the ends of the

wires from the left speaker’s posi-

tive terminal and the amplifier/

receiver’s left positive speaker ter-

minal.

2. Position the twisted wire ends

between the open barrel ends of

the Speaker Pin.

3. Using a pair of pliers, crimp down

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 SW-

200P.

CONNECTING TO

POWER

Plug the PRO SW-100P’s AC power

cord into an AC outlet.

ADJUSTING THE

VOLUME

Once you have made all connections,

follow these steps to adjust the volume

control.

1. Rotate VOLUME CONTROL on the

front of the subwoofer to MIN.

2. Turn on your amplifier/receiver

and another component (such as

a radio, cassette player, CD

player, or turntable).

3. Begin play of an audio source

(such as a CD) and adjust the

amplifier/speaker’s overall volume

to a comfortable level. Rotate VOL-

UME CONTROL clockwise, a little

at a time, until you achieve a

pleasing balance of bass between

the PRO SW-200P 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 VOLUME

CONTROL, use the amplifier/

receiver’s volume control to con-

trol the speakers’ volume.

ADJUSTING THE HIGH

CUT FREQUENCY

FREQUENCY HZ adjusts the level (be-

tween 50 Hz and 200 Hz) at which the

subwoofer begins passing frequen-

cies to other speakers. This control’s

setting depends on the low frequency

capabilities of your satellite speakers

(if used), speaker placement, and oth-

er factors that affect bass perfor-

mance.

To adjust the high cut frequency, first

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 FREQUEN-

CY HZ counterclockwise a little, then

rotate VOLUME CONTROL clockwise

by about the same amount. This in-

creases low bass output without affect-

ing the mid-bass output.

To reduce low bass output without af-

fecting the mid-bass output equally, ro-

tate FREQUENCY HZ clockwise and

VOLUME CONTROL counterclockwise.

Note: Set FREQUENCY HZ to 200 Hz

when using the PRO SW-200P with

the Mini Home Theater Satellite

Speakers (RadioShack Cat. Nos. 40-

4082/4083) and Mini Home Theater

Center Speaker (Cat. No. 40-4084).

CARE AND

MAINTENANCE

Your Optimus PRO SW-200P 200-

Watt Powered Subwoofer is an exam-

ple of superior design and craftsman-

ship. The following suggestions will

help you care for your subwoofer so

you can enjoy it for years.

• Keep the subwoofer dry. If it gets

wet, wipe it dry immediately. Liq-

uids can contain minerals that cor-

rode electronic circuits.

• Use and store the subwoofer only

in normal temperature environ-

ments. Temperature extremes can

shorten the life of electronic

devices, and distort or melt plastic

parts.

• Handle the subwoofer gently and

carefully. Dropping it can damage

circuit boards and cases and can

cause the subwoofer to work

improperly.

• Keep the subwoofer away from

dust and dirt, which can cause

premature wear of parts.

• Use only fresh batteries of the rec-

ommended size and type. Old bat-

teries can leak chemicals that can

damage your subwoofer’s elec-

tronic circuits.

• To maintain the cabinet’s finish, do

not let it come into contact with

water vapor, alcohol, benzene,

insecticide, or similar liquids. Do

not place a plastic covering on top

of the cabinet, as the plastic’s

color could come off and stick to

the finish. Clean the subwoofer

cabinet with a soft, dry cloth.

• Never touch the subwoofer ele-

ments with your hands or expose

them to excessive shocks. If the

subwoofer is dented or bent, the

sound is distorted as well.

Modifying or tampering with the sub-

woofer’s internal components can

cause a malfunction and invalidate

your subwoofer’s warranty. If your sub-

woofer is not performing as it should,

take it to your local RadioShack store

for assistance.
