Special functions:
Connecting two DMA1s in cascade via the V-link connection
and the audio inputs/outputs can recreate the typical
operating mode of a commercial radio station.
One DMA-1 (A) is programmed to run in
playlist mode, to play the music content
(PLAYLISTS.TXT).
A
The other DMA-1 (B) is programmed to run according to
a schedule (PALIN.TXT) to play commercials and\or
announcements.
