Cobham’s N301A Single-User Audio Controller is compatible with military and civilian aviation headsets, controlling the audio from multiple receivers, allowing transmission of mic audio to a selected transmitter.

The N301A Single-User Audio Controller may be used in new installations where single- or multiple-user networks (up to 10 stations) are required.  Additional internal inputs have been added to improve airframe alerting capability.  Each N301A panel is self-contained, with solid state modular plug-in construction, sealed switching devices for low noise and gold switch/relay contacts for long life.  Removable legends give operators maximum tailoring flexibility. 


Dzus-mounted, the N301 is available in standard configurations or customized panel layouts, with 5 VDC or 28 VDC standard white lighting, plus optional NVG-friendly/NVIS-compliant lighting.
