System 2; Simple Configuration - Rear Power Input
This example is similar to the System 1 diagram except the power supply from the LCAi220 is
connected to the rear input with the power routed from a central location (usually located with
the central music source equipment). Also a RVC90i volume control is added for volume
control of the central music source when the LCAi220 is in bypass mode.
