Designed to be the basic control unit for a multi-position, up to 12 stations intercommunications system. The A301-12-1 is an advances Intercommunication Control System designed to meet current and future requirements of Military Communications.

This panel has two fuel boost pump control switches and two boost pump advisory indicators. Panel lighting is 115VAC and is NVG compatible. This panel is used on the UH-60 Black Hawk. NSN 1680-01-216-1923

A panel-mounted assembly designed to provide high intelligibility intercommunication and radio monitoring facilities for airborne and ground installations. The Set Control also provides for selection, control, and modulation of radio transmitters for communications with airborne, ground, or mobile stations.

Andrea designs and manufactures special test equipment for the items we produce. These test sets permit simple and rapid testing and troubleshooting of the various control units, amplifiers, and other modules.

Relay assembly units used in conjunction with military transceivers to provide secure communications. The A649 contains 4 relays while the A652 contains 3 relays and an electronic switching circuit. The relays are special low capacitance types which provide more than 100 dB of isolation between circuits

Designed to be the basic control unit for a multi-position (up to 12) intercommunication system of advanced design. It is a high reliability unit employing solid-state relay circuits and modular microphone, headset, and speaker amplifiers. It will provide specified performance from a 5 ohm Dynamic Microphone or a 100 ohm carbon microphone and an 8 ohm or 600 ohm headset. FAA TSO-C50b approved.

The Andrea Model A301-14A is a bulkhead mounted intercommunication station utilizing the same high performance amplifiers
as the Model A301-12-1. It was designed for and is being used in the U.S. Navy Air Cushion Landing Craft.
The A301-14A is a rugged, high reliability unit that can be used in many applications requiring an intercom station.
The only operating control on the A301-14A is a Volume Control on the front panel.

Designed to provide hands-free operation in an interphone system without the objectionable background noise when no signals are present. The fast attack time and loss less circuit insure no deterioration of the desired signal.
