Itel DPRO3 FM Digital Audio Broadcast Processor

DPRO3 is a 3 band FM broadcast audio processor with integrated MPX and optional RDS encoder. The processing chain comprises a wide band AGC which feeds the 3 bands audio processor.
This configuration allows for a good on air presence, combined with a natural and transparent sound.

The audio processing and RDS/MPX encoders are realized by DSP, allowing a stable operation over time and the possibility to implement new functions through software updates.
An optional ethernet streaming card allows to play MP3 / AAC streams and files, thus forming a complete stream to MPX RDS receiver for use as a spare audio source or network STL.

In this case, the audio signal coming from network will be directly processed by the DSP and converted to analog only at MPX output, thus realizing an entirely digital processing chain.
