SW 50 Overview
The AudioSource SW 50 represents the state of the art in powered subwoofers. The highly efficient ported
enclosure houses a rugged eight-inch, reinforced driver, a fifty-watt amplifier, and a passive low frequency
crossover network. This precision matched combination ensures the SW 50 will deliver the best sound possible,
under even the most demanding conditions. The input level is variable over a wide range, allowing the SW 50
to complement a wide variety of systems. Line and hi level inputs are provided for fast and easy connection
to virtually any system. The two-way auto power function completes the generous list of features offered by
the SW 50.
A Few Words about Subwoofers
Subwoofers are designed to extend the bass response of your system beyond the limitations of most
speakers. This unit is to be used in conjunction with, not in place of, your existing left and right speakers.
The low frequency sounds reproduced by the subwoofer will radiate equally in all directions. It is not neces-
sary to have a pair of subwoofers. A single subwoofer can dramatically enhance a stereo TV, a stereo system,
or a full fledged home theater.
The advent of digital recording has increased the amount of low frequency information found on recorded
material. Subwoofers are designed to accurately reproduce this bass. Similarly, most movies intended for
home viewing feature bass well below the musical range of traditional loudspeakers. However, this information
is vital to the impact, ambiance, and believability of a scene. A subwoofer enhances those elements in your
home theater.
Placement Guidelines
Prior to installing your new AudioSource subwoofer, please consider the following guidelines. Placing the
subwoofer near a wall or in a corner will greatly increase its bass response. As frequencies reproduced by sub-
woofers are long and need room to propagate, a subwoofer placed near the listening position will not sound as
full as one placed farther away.
Finally, the cabinet of your AudioSource subwoofer is designed to blend in with most decors. If you
decide to place anything directly atop your subwoofer, please use great caution, as the speaker cabinet will
vibrate and items placed on top may shake loose or fall.

Using the Controls
Power
The power switch has two
positions: off and auto. The auto
position is the default setting. This
keeps the amplifier in a standby
mode. Using sophisticated signal
sensing circuitry, the amplifier is
instantaneously activated when a sig-
nal is detected at either of the inputs.
If no signal is detected after several
minutes, the amplifier switches back
to the standby mode. The off position
overrides this circuit, turning the subwoofer off manually. The power LED indicates the subwoofer's status.
Level
Since your subwoofer is designed to work in conjunction with other speakers, we have provided a level
control will allow you to balance the output of your unit with the rest of your system. Once set, the level
control should not require further adjustment. Begin with the level control at the minimum position. Slowly
increase the level until the subwoofer's output is equal to that of your other speakers.
Note: Output level is relative and can be different from location to location. Always return to the normal listening
location to evaluate any setting changes.
Connecting the SW 50
General Information
The diagrams on the following pages show three of the most common types of subwoofer connections. This
information will guide you through the connection process.
First, a few words regarding the functioning of your powered subwoofer: All signals into your powered
subwoofer will first pass through the crossover. The portion of the signal below the current crossover fre-
quency setting will be reproduced by the subwoofer. The unprocessed signal will be passed to the hi level
outputs. If you have a choice of connection options, remember that it may be easier to run long distances
with speaker wire than with line connectors.
Hi Level In
These inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power
amp or other device not equipped with line level outputs.
Hi Level Out
The original amplified signal from your source is present at these outputs for connection to the existing
left and right speakers.
Line In
These RCA jacks are designed to accept a line level signal from a receiver, pre-amp, surround sound
decoder or similar device. When using a single line level output from another unit, a Y connector should be
used to send the signal to both the left and right inputs. (Using the tape loop of a receiver or preamp is not
recommended. Tape jacks typically send a constant level, regardless of the volume setting, unlike preamp
outputs. This will affect the balance between the subwoofer and the rest of the system.)

Here the signal is already amplified as it leaves the receiver/amplifier. The speaker terminals of this unit
are connected to the hi level inputs of the SW 50. The left and right speakers receive the original amplified

Dedicated Subwoofer Connections
Many surround sound decoders, home theater processors and audio/video receivers are equipped with a
dedicated subwoofer line output. In this case, the signal is already processed and does not need to return to
the system or other speakers. Connect this line output to the line inputs of the SW 50. A Y connector should
be used to feed this single output to both the left and the right line inputs.

Television Enhancement
Many newer television sets are equipped with variable stereo outputs. The signal available at these
outputs varies with the television volume. In this situation, these variable audio outputs can be connected
directly to the SW 50 line inputs to enhance the bass response of the television's built-in speakers.
