Omnia.9 Technology in a 1RU Standalone Stereo Generator

In some applications, it might make more sense to locate the main audio processor at the studios while the stereo generator and limiter live out at the transmitter site. This might include cases where the STL uses discrete analog or AES audio rather than composite, or situations where one primary audio processor feeds multiple sites such as satellite distribution.

Omnia.9sg brings the same acclaimed clipper, limiter, and stereo generator technology in the Omnia.9 to a standalone box—but that isn’t all it does…We brought a few other tricks from the Omnia.9 along for the ride.



  • Composite embedding allows up to 140% L/R modulation at 100% total modulation.
  • Full IP remote control with remote audio streaming
  • Optional RDS encoder
  • Selectable SSB (Single Sideband) stereo encoder
  • Analysis tools for internal or external composite signals



Psychoacoustically Controlled Distortion Masking Clipper

As with the Omnia.9, the psychoacoustically controlled distortion-masking clipper built into the Omnia.9sg allows for incredibly loud audio without distortion.


ITU-BS.412 MPX Power Controller

With all of this capability for ultimate loudness and modulation, the ITU-BS.412 MPX Power Controller ensures you remain compliant with applicable regulations while still producing competitively loud yet clean audio.


Auto Pilot

Another feature carried over from the Omnia.9 into the 9sg is the unique “Auto Pilot” function. Turning off the stereo pilot during mono programming allows for a 20 dB signal-to-noise improvement
when it counts the most. Auto Pilot will automatically suppress the 19 kHz stereo pilot during mono programming ensuring that your programming stays as noise-free as possible.


Full Remote Control

While the front panel LCD allows basic configuration and monitoring, the Omnia.9sg has a complete IP remote control interface. NF Remote software (also used with many other Telos Alliance products) can control the unit and access the same full suite of test instrumentation available in the Omnia.9. External composite signals from modulation monitors can also be analyzed and streamed through the remote software for off-air monitoring.
