RCA PRO-SW220P User Manual

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 bass­reflex enclosure to produce tight, floor­rumbling 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.

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.

High-Level Input — lets you connect the
subwoofer to an amplifier’s or receiver’s
speaker outputs.

This symbol is intended to alert
you to the presence of uninsu­lated dangerous voltage within
the product’s enclosure that
might be of sufficient magnitude
to constitute a risk of electric
shock. Do not open the product’s
case.

This symbol is intended to
inform you that important operat­ing and maintenance instruc­tions are included in the
literature accompanying this
product.

!

• 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.

• T o pr event 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.

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.

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.

• 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 non­directional, 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 can connect your PRO-SW220P to an
amplifier/receiver’s subwoofer out or pre
out jacks or speaker terminals.

Note: You can connect your PRO­SW220P 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
