PRO SW-200P 200-Watt Powered Subwoofer
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.
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.
High 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.
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!
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.
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.

Cautions:
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.
• 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.
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.
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.
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.
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.
Caution: To avoid any damage to the
subwoofer or amplifier, disconnect
power from your components before
making any connections.

Note:
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.
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.
2. Connect your satellite speakers (if
any) to the amplifier/receiver’s out-
put terminals as they would nor-
mally be connected.

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.

Plug the PRO SW-100P’s AC power

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.

• 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.
