Omnia Releases MPX Node

The STL gets simpler

An oft-ignored area where IP technology is looming as a transformative presence that will rewrite work practices is the STL.

With that in mind, The Telos Alliance’s Omnia Audio brand has developed the MPX Node, a pair of IP devices that send a post-processor composite signal from the studio directly to the transmitter site via IP.

The pair are configured as an encoder, to be placed at the studio after the processor, and a decoder, waiting at the transmitter site, ahead of the transmitter itself. In between them is likely to be the public wired internet but it could be a wireless IP radio link.

Omnia helpfully explains, “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.”

A single MPX Node encoder can send its signal to multiple MPX Node decoders simultaneously. According to Omnia the pair can work as low as 320 kbps.

Keeping within the Omnia family, the Omnia.9, using the µMPX codec, can send the processed composite signal directly to the MPX Node decoder.

However, the encoder is processor-agnostic, so long as the processor outputs a composite signal.
