8.1 Connection of two DMA1s

Connecting two DMA1s in cascade via the Vlink connection and the audio

inputs/outputs (see fi gure), can recreate the typical operating mode

of a commercial radio station.

One DMA1 must be programmed to run in playlist mode, playing the musical

items (PLAYLISTS.TXT), the other DMA1 is programmed to run according to

a schedule (PALIN.TXT) playing the commercials/spot announcements.

DMA1 with playlist

DMA1 with palimpsest

When a time event is to be played the schedule-programmed DMA1 waits

for consent (the completion of playing the current MP3 music fi le) from

playlist-programmed DMA1, (which goes into standby), before starting to

play the commercials/spot announcements.

Once the playing of the time event is over, the playlist-programmed DMA1

will start to play the following MP3 music fi le in the playlist.
