The Telos Alliance® revolutionized the modern broadcast facility with the invention of Audio over IP. We proudly extend the AoIP revolution we began in the studio out to the transmitter with the Omnia MPX Node. 

Like its namesake—the classic Axia® xNodeTM—Omnia MPX Node is a building-block technology that helps stations leverage the growing power and capability of data networking. The Omnia MPX Node is the first purpose-built hardware codec capable of sending or receiving full FM signals at data rates as low as 320 kbps utilizing the Omnia μMPXTM algorithm, ideal for networks with limited capacity (including IP radios). MPX Node makes peak-controlled L/R baseband, stereo pilot, and RDS data routable from a studio to one or many FM transmitters. By transporting an FM composite signal rather than left/right audio, broadcasters can keep their on- air processing and RDS encoding at the studio, then deliver a transmission-ready, peak controlled FM multiplex signal directly to an FM transmitter without the need for transmitter-side peak limiting or stereo generation. The MPX Node is available as either an encoder or decoder, and a pair of units creates an end-to-end system.



  • MPX Node is available as either an Encoder or Decoder 

  • Omnia μMPX algorithm can transport FM composite (MPX) and RDS/RBDS at selecta variable rates from 320 kbps up to 576 kbps —perfect for IP radios and DSL IP circuits and other lower bandwidth connections 

  • Built-in, configurable error correction 

  • Processor agnostic design: Encoder can be fed by any brand of FM audio processor 

  • Omnia.9 or OmniaSSTTM processing software can serve as the Encoder front end 

  • MPX Node Decoder outputs a standard analog MPX signal to feed any FM transmitter 

  • Full FM signals (including RDS/RBDS) can be sent over IP networks 

  • 5 In x 5 Out GPIO 

  • A single Encoder can transmit the same signal to multiple decoders 

  • Separate Ethernet ports support independent, dual networks 

  • Redundant networking allows the same signal be sent/received over two ISP’s 

  • Simple HTML.5-based web GUI allows you to control MPX Node from your desktop, tablet, or smartphone 

  • Dual bank firmware update design, for secure upgrading
