Progammable functions:

DMA-1DMA-1

• Audio announcement sequences cyclically issued, consisting in single files or 8-file blocks, with 60mins. Max of programmed sequences.

• DMA-1 has an audio input to connect external music sources: at the scheduled event the audio input fades out as per programming.

Progammable 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.
