AudioSource LS 300 - Manual (Page 3)

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 300
The following diagrams show three of the most common types of subwoofer connections. It may be easier to run long distances with
speaker wire, although RCA-type connectors will likely produce better sound. Use only the AC adapter provided with this unit.
Speaker/Hi Level Inputs and Outputs
The inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power amp, television or other device not
equipped with line level outputs. The speaker outputs are meant to connect to the inputs of your main left and right speakers. These
are only used when the speaker inputs of the SW 300 are used.
Line In
The RCA-type jacks of your SW 300 are designed to accept a line level signal from a re c e i v e r, pre-amp, surround sound decoder, television
or similar device. When using a single line level output from another unit, a Y connector (not included) should be used to send the sig-
nal to both the left and right inputs.
Please note that only one of these connection options should be used at any one time.

Hi Level Connections
In this example, the receiver has no subwoofer output.
The SW 300 is connected between the front speakers
and the receiver via the speaker inputs and outputs.
Dedicated Subwoofer Connections
Many sur round 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 300. 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 300 line inputs to enhance the bass response of the
television's built-in speakers.
