AudioSource System 2.5 - Manual (Page 3)

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.
