DEVA DB94‑RX MPX over IP Decoder with MicroMPX

Product overview

The DEVA DB94-RX MPX Decoder is a compact MPX over IP decoder designed as a reliable endpoint for modern FM STL and distribution networks. Built around the MicroMPX algorithm from Thimeo, it reconstructs full FM MPX from low-bitrate IP streams while preserving stereo and RDS integrity. The DEVA DB94-RX MPX Decoder combines DSP-based decoding, forward error correction and flexible backup options to maintain audio even on imperfect networks. It integrates easily with FM transmitters and fits alongside other DEVA IP audio devices at transmitter or hub sites.

Key features

• Compact FM MPX over IP decoder based on MicroMPX technology
• Supports μMPX and PCM streams with selectable bitrates and sample rates
• Ultra low latency, all-digital DSP design for real-time FM STL use
• Forward error correction, RIST and Pro-MPEG FEC for robust streaming
• Analog MPX and AES192 digital MPX outputs for direct transmitter feeding
• Backup audio playback and configurable input failover logic
• Embedded HTML5 web server with HTTPS, SNMP and alarm notifications
• Rugged aluminium enclosure optimised for 24/7 broadcast operation

Connectivity and I/O

The DEVA DB94-RX MPX Decoder provides a Gigabit Ethernet port for IP streams and management, analog MPX output on BNC and AES192 digital MPX on RJ-45 for transmitter inputs. Additional interfaces include GPIO alarm contacts, USB for backup audio, a DC power connector and, where fitted, GPS sync input for timing-critical deployments.

In operation

In daily use, the DEVA DB94-RX MPX Decoder delivers stable MPX output with clear front-panel indicators and an intuitive web interface accessible from common browsers. Engineers can adjust stream profiles, FEC settings, backup sources and alarms remotely, ensuring reliable audio at single or multiple transmitter sites. Its efficient design and proven DEVA hardware platform make it a practical choice for FM networks needing bandwidth-efficient, resilient MPX over IP decoding.
