Access/A A710 Audio Control Panel
Technisonic high performance audio control stations
A710 Custom Legend Overlay

The ACCESS/A system is based on an integrated family of modular, field configurable, panel mounted controls, coupled with external special function units, which produce a complete airborne communications suite. This flexible audio system architecture supports extensive transceiver support, multiple ICS busses, alerting, warning and signaling functions, voice message storage, partitioned crews, and greatly expanded interface capabilities.

ACCESS/A is the physical layer of interconnection and interface between Airborne crews and their radio systems, as well as providing internal intercom, internal and external paging, airframe alerting, music and entertainment functions. ACCESS/A makes multiple independent crew groups with cross-linking easy to implement for applications like emergency medivac or forestry aircraft, and delivers high performance solutions for the complex multitransceiver communications found in SAR, customs, emergency services and police aircraft.
