Applications

This decoder is ideal for radio stations needing a stable and professional studio-to-transmitter link. It can receive uncompressed PCM audio from encoders such as the Escape PCM STL Radio Link Encoder, or connect directly to Shoutcast/Icecast internet streams. From there, it generates the stereo MPX signal for FM transmitters, ensuring consistent, on-air broadcast quality.
