Commercial Radio Interface (CRI-1)


The CRI-1 allows the integration of a wide range of commercial radio equipment into an aircraft audio system. The CRI-1 provides microphone bias, relay keying and sidetone generation. It also provides adjustable microphone and audio outputs that are isolated from airframe ground. A wide range of radio microphone inputs can be accommodated through the appropriate selection of a resistor impedance network.

The CRI-1 is CASA APMA and STC approved for installation into the Eurocopter AS 355F1 Series. For limitations and conditions please refer to  STC ASA096SY.
