VIC Capabilities

The audio frequency amplifier is the main junction box for the VIC-1

AM-1780

system. It provides control of DC power to associated control boxes

and to the radio system connected to the AM-1780 amplifier. It also

amplifies and controls audio signals in the intercom and radio circuits.

When a combat vehicle crew (CVC) helmet cord is connected to a

C-2298/C-2297

control box, the crewmember can select, by means of the MONITOR

switch and CVC controls, to communicate on the intercom or on a

radio.
