17—Program Input
A three-terminal, plug-on connector provides the program input to the station.
Program is fed to the headset and speaker. The level to the speaker or
headset is controlled by the Program Level control. The Program Input
accepts a balanced or unbalanced line-level audio signal from -20 dBv to +10
dBv. If this input is connected to the stage announce (SA) output of a Main
Station it can be used as a paging input. Since the level of this input is
independently adjustable from the intercom audio volume, it can be used to
override the intercom audio. The pinout of this connector is as follows:
•
Pin 1— Ground (Shield)
•
Pin 2— + Signal
•
Pin 3— - Signal.
