General Instructions SCOPE This section provides detailed operating instructions for the PS Engineering PMA4000 Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This section is divided into three sections covering the basic operating areas of the PMA4000 systems. They are: Audio Selector, Transceiver Selection and Intercom.
Intercom Mode Selector Switch Unit power is turned on and off by the mode selector switch. In the OFF or "FAIL-SAFE" position, the pilot is connected directly to Com 1 allowing transmit and receive capability regardless of unit condition. Any time power is removed or turned OFF, the audio selector will be placed in the failsafe mode. The switch is a 3-position mode switch that allows the pilot to tailor the intercom function to best meet the situation.
lected transceiver is automatically heard in the headsets and speaker (when selected). You can check this function by switching from COM 1 to COM 2 and watch the selected audio light on the selector change from C1 to C2. This ensures the pilot will never transmit on a radio is not listening to. When switching from COM 1 to COM 2 while Com 2 has NOT been selected, Com 1 audio will be switched off. In essence, switching the mic selector will not effect the selection of Com receiver audio.

radio and transmit sidetone). This will be heard in all headsets and speaker (if selected). To hear older messages, push the playback button repeatedly to “back up” the recorder, until the desired message is heard. Holding the IRS playback button for three seconds will stop the message playback and queues the system to the next preceding message. This allows quick access to previous messages. The recorder is a continuous loop, and newest ones will overwrite the oldest messages.
