Main bus inputs allow outputs from
receivers, CD players, TVs, or any
stereo audio sources to be amplified
across all channels for easy multi-
room applications. Auxiliary inputs
allow an additional audio source to
be played on any channel that is
switched to AUX.

Bus outputs allow the
bus inputs to be sent
to other amplifiers or a
daisy chain without the
need for ‘Y’ cables or
splitters. Auxiliary out-
puts allow you to daisy
chain the input to
other audio sources.
