Broadcast Quality MPX Decoder

The Escape MPX STL Radio Link Decoder is designed to receive full MPX composite signals over IP and deliver them directly to any standard sound card for FM transmission. Used together with the Escape MPX Encoder, it provides a complete end-to-end STL solution for radio broadcasters.

Applications

This decoder is ideal for transmitter sites where the complete MPX signal needs to be fed directly into the FM exciter. It ensures crystal-clear, broadcast-quality composite audio reception 24/7, even across long-distance IP connections.

Key Features

  • Receives MPX composite signal over IP for FM transmission.
  • Deviation meter (0–120%) for live monitoring.
  • Configurable sound card latency for precise playback adjustment.
  • Adjustable Audio Delay with Buffer Size and Audio Sync Delay.
  • Buffer Limiter prevents latency drift by stabilizing the buffer.
  • Refresh on Low Buffer recovers automatically if the buffer drops too low.
  • Selectable audio output device and receiver port.
  • Supports auto-start and background operation via system tray.

Challenge & Solution

Delivering MPX signals reliably over IP has traditionally been a challenge due to latency and network instability. The Escape MPX Decoder ensures uninterrupted, stable reception with advanced buffering controls and real-time monitoring. Together with the MPX Encoder, it replaces costly hardware STL links with a powerful and flexible IP-based solution.

License

The software license is valid for a single activation on one computer. In case of hardware migration or replacement, a new license is required.
