Mono Connection Diagram - Bose PROFLIGHT Owner's Manual

Connect the eight wires as follows:
Two for the microphone
Two for audio
One for power
One for ground
Two for audio shields
Audio and microphone wires should be connected to the back of the existing
microphone and headphone jacks, leaving existing jacks intact for use with
conventional headsets. This is usually the fastest installation method.
CAUTION: Do NOT use excessive force or bend the installed connector. This may
damage or break internal solder joints.
NOTE: The aircraft panel connector cannot be installed in an audio system using
transformer-coupled audio outputs. Contact Bose technical support.
