    Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and allow radio transmission. In "Split Mode" the PMA450A has the ability to allow the pilot to transmit on Com 1 while the copilot can transmit on Com 2. A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe) position.

    2.4.1.1 Music Inputs and Noise PMA450A units utilize a differential input to help prevent noise from entering the music system. This feature is usually transparent to the installer; however, it is important that the appropriate music signal and ground connections are made directly to the dedicated music signal and ground inputs on the PMA450A. The power for IFE and audio panel should be a common bus.
