The AMI MIC-0004 internal microphone is designed to capture bridge conversations and ambient audio for recording by compatible AMI Marine voyage data recorder systems. It operates on 12 V DC supplied by the MEU and uses a 600-ohm balanced audio output to help reduce electrical interference. Its built-in self-test functionality supports system performance testing, while the plug-and-socket connection simplifies installation.
