DPRO6 is a FM broadcast audio processor with integrated MPX and RDS encoder.
The processing chain comprises a two band AGC which feeds the 6 bands audio processor.
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.
