Figure 3-4 Standard Music Distribution
When the music is standard, Music 1 will always go to the pilot and copilot positions, and is never
heard
by the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and copilot.
This mode is useful if your passengers have a different interest in entertainment or are watching a DVD,
but do not want to be excluded from the intercom conversations.
3.11 Internal Recorder
The PMA8000B comes equipped with an internal recorder. This digital system stores the last incoming
audio from the radio you have selected for transmit. It can store as many of 16 incoming messages, and up
to 30 seconds of audio. The pilot and copilot hear the playback. It is also possible to modify the unit to
exclude the copilot from the playback, and annunciation playback. Contact PS Engineering, for more de-
tails. [In systems with serial number J01860 and below, only the pilot will hear the playback.]
3.11.1 Playback
Recording is automatic. To play back the message, press and hold the RCV button for the communications
radio that is selected for transmit for about 1 seconds or until the message plays back.
To stop the, hold the same button until the playback stops, about 2 seconds. Then the next 1-second press
will play the next earlier message stored.
The playback will stop automatically when the selected com audio becomes active again. Press the button
again to start the message again. The audio received during playback is NOT stored.
