AN/VIC-1
Description
The AN/VIC-1 Intercommunication Set provides voice communication between two to five vehicle crew members. It is used in those vehicles that do not have an intercommunication system as a part of a radio set. It consists of two major components: a Control Intercommunication Set C-2298/VRC is installed for each crew member who is to use the radio equipment (in a tank it is installed at each crew position except the drivers'), and an Amplifier, Audio Frequency, AM-1780/VRC, which amplifies the voice signals and controls their distribution throughout the system. Installation kits provided for specific vehicles may include other control boxes and audio accessories that are used in conjunction with the AN/VIC-1 Intercommunication Set. In addition, cable assembly, special purpose electrical CX-4720/VRC is used to connect the vehicular power supply to the amplifier and one CX-4723/VRC is used to connect the amplifier to each control box. While typically the AN/VIC-1 is used in vehicles, it may be used for non-vehicular installations when the correct DC power source is available. It has two line binding posts that may be used to connect a remotely located telephone or switchboard into the vehicular intercommunication system. The AM-1780/VRC Audio Amplifier is the main function box for the Intercommunication System. It has controls for both power and also amplification. The AM-1780/VRC provides connections between the amplifier and the crew members' audio accessories. It has a volume control and a radio/intercommunication selector switch. This unit amplifies intercom as well as received audio signals. It also functions as a main control box and an interconnection junction. As a control box it distributes power for intercom and radio operation, permits transmission by the commander or crew, and accentuates intercom audio to override the received signal. As a junction box, it interconnects the radio set and intercom system.
Additional Accessory Usage
The VIC-1 can allow a number of additional accessories to be used, these include microphones H-250/GR or H-189/GR, speakers LS-454/U, plain headsets like the H-140A/U or H-161A/U.
