(GPI)

There are 16 analog /digital control inputs, referred to as "General Pupose Inputs" or "GPI"� The General
Purpose Inputs are used to connect switches (for control of mutes) or potentiometers (for control of volume)�
GPI connections are made using the included black 12-pin terminal-block connectors (HARMAN part number:
32-1006)�

There are two common ground ("C") pins to the left and two reference voltage ("R") pins to the right that
provide an output of ~5VDC�
