SW 80 Powered Subwoofer
About Subwoofers
Subwoofers extend the bass response of your system beyond the limitations of most speak-
ers. They are used with, not in place of, your existing left and right speakers. A subwoofer
can dramatically enhance a stereo TV, a stereo system, or a full fledged home theater.
Features of the SW 80
The AudioSource SW 80 features a highly efficient ported enclosure, a rugged 8-inch rein-
forced driver and a eighty-watt amplifier with a passive low frequency crossover network.
A line level input is provided for fast and easy connection to virtually any system.

Using the Controls

Power
The power switch has two positions: off and on. When the power LED is lit, the power is on.
Level
The level control adjusts the volume of the SW 80. Once set, the level control should not require further adjustment. Begin with the
level control at the minimum position. Slowly increase the level until you can hear the subwoofer. A subwoofer playing too loud can
give your system a muddy sound, so be sure to balance the subwoofer carefully with your other speakers. Output level is relative and can
be different from location to location. Always return to the normal listening location to evaluate any setting changes.

Placement Guidelines

Prior to installing your new 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 subwoofers are long and need room to propagate, a subwoofer placed
near the listening position will not sound as full as one placed farther away. Please be careful about placing anything directly on top of
your subwoofer, as the vibrations of the speaker cabinet could cause these items to shake loose or fall.
Connecting the SW 80
The following diagrams show the most common types of subwoofer connections. Note Use only the AC adapter provided with this unit.
Line In
The RCA-type jack of your SW 80 is designed to accept a line level signal from a receiver, pre-amp, surround sound decoder, television
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.
Dedicated Subwoofer Connections
Many surround sound decoders, home theater processors
and audio/video receivers are equipped with a dedicated
subwoofer line output. Connect this line output to the line
inputs of the SW 80. A Y connector (not included) may be
necessary 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
TV volume. In this situation, these variable audio outputs can
be connected directly to the SW 80 line inputs to enhance the
bass response of the television's built-in speakers.
