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.
