System 1; Simple Configuration - Front Power Input
In this example, the central music source (receiver located in another part of the house)
provides the default audio for the room. Signal sensing on the RCA connections will trigger the
local source (audio from the TV configured to variable output). Power is connected to the front
input. For additional bass, a powered subwoofer may be used.
