AudioSource System 2.5 owner manual Hi Level In, Hi Level Out, Line In, Hi Level Connections

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

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.

Hi Level Connections

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 80. The left and right speakers receive the original amplified signal from the SW 80 hi level outputs.

Line Level Connections

In this example, the pre-amp outputs of a stereo receiver are connected to the SW 80 line inputs. The line outputs on the SW 80 return the line level signal to the power amp inputs on the stereo receiver, which in turn powers the left and right speakers.

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 80 line inputs to enhance the bass response of the television's built-in speakers.

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 80. A Y connector should be used to feed this single output to both the left and the right line inputs.
