Omnia MPX Node Overview
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.

Your Processor is the STL
Imagine if your FM processor was also the front end of your transmission link. With an Omnia.9 at the studio, a stable IP link, and an MPX Node Decoder, you have a complete STL!
In this scenario, your Omnia.9 FM processor (with μMPX license installed) can be located at the studio. With IP addresses correctly set, Omnia.9 routes MPX/RDS data to one or many Omnia MPX Node Decoder(s) at one or more transmitter sites. The MPX Node (Decoder) then feeds your FM transmitter with a standard analog MPX signal. The Omnia MPX Node preserves all the complex peak limiting, stereo generation, and RDS (if provided), as if your FM processor were at the transmitter. The result is less equipment, fewer steps, and fewer points of failure between your processed signal and your transmitter.
Works with any Audio Processor
If you don’t have an Omnia.9, no worries. A pair of MPX Nodes is all you need to transport the MPX signal (and RDS data) from your FM processor to your transmitter. MPX Node works with any FM processor with a stereo generator to transport a composite (MPX) signal over IP.
Backup STL or Translator Link
The Omnia MPX Node makes a perfect backup link to your main studio or translator. With μMPX, lower bandwidth connections, such as IP radios can be employed to get a composite signal from studio to transmitter, without the need for further peak control or stereo generation on the transmitter end.
Multi-Frequency Networks or Multiple Sites
With UDP (unicast) distribution, a single encoder can feed multiple decoders. Your FM signal can be routed point to multipoint over different IP connection types and carriers, including over the Internet. A base unit can send 2 streams. Up to 16 streams are supported with 2 and 4 stream licenses.
With an optional license, Decoders can subscribe to multicast streams generated by MPX Node encoders, for private networks supporting multicast traffic.
Redundant Network Support
With 2 independent network ports and internal stream replication, duplicate streams can be sent over 2 separate IP links from an Encoder. In the event of packet loss on one carrier, data is seamlessly spliced in from the second link on the Decoder for full redundancy.
