Datron’s Analog Intercom System (AIS) is a compact intercom system specially designed for crew intercommunications and radio access in tactical vehicles. Easily installed and operated, the AIS System provides crisp, clear, full duplex intercommunications among crewmembers. A single crew volume control knob provides a 28dB range of listening volume adjustment. The system provides DC power through the crewmember connection ports to enable the use of Active Noise Reduction (ANR) equipped headgear. The system accommodates up to five crewmembers. AIS is compatible with Datron’s radio product line and most other military radios as well as many professional radios.
