Amplifiers convert the oxygen mask’s M-101 microphone to work with civilian aircraft radios. Insert the PA-12 amplifier between oxygen mask nose piece and the CX-4707 mask cord. Use the PA-102 to connect the nose piece directly to a helmet cord. Available in standard size and extended 14" size.

PA-12 amplifier is used with CX-4707 oxygen mask communication cords.

PA-101 amplifier with 14” microphone cord is used if the helmet has a cord that plugs into the aircraft.
