AudioSource SW 15 - Line Level Connection Example; Hi Level Connection Example; Dedicated Subwoofer Connection; Television Enhancement Connection

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 Fifteen.
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 out-
puts can be connected directly to the SW Fifteen line inputs to
enhance the bass response of the television's built-in speakers.
Line Level Connections
In this example, the pre-amp outputs of a stereo receiver are
connected to the SW Fifteen line inputs. The line outputs on
the SW Fifteen return the line level signal to the power amp
inputs on the stereo receiver, which in turn powers the left and
right speakers.
