Omnia XII Overview

The culmination of decades of audio processing expertise and experience from Frank Foti and the Omnia team comes together in their best-sounding and most forward-thinking processor to date: Omnia XII.

A processor is more than hardware you rack up and plug in, or a collection of algorithms and parameters to adjust. It is a way to connect you with your listeners and create a visceral, emotional experience they can feel as well as hear.

Omnia XII’s architecture allows us to put our best foot forward today while paving the way for new features, sonic improvements, and whatever tomorrow demands via software updates.

Omnia XII’s Wideband AGC + 5-band multiband AGC and compressor + 6-band multiband limiter processing design, dynamic EQ, and unparalleled bass management features pair up with our most advanced clipper design yet, delivering a clear, warm, powerful sound that delivers effortless loudness, even at major-market levels.

As with all Telos Alliance products, Omnia XII is backed by our industry-renowned, world-class support.

Omnia XII In Depth

The content you create and broadcast - whether it’s today’s latest music and familiar feel-good hits from decades past, or late-breaking news, talk, and sports - is more than sonic wallpaper. It is an opportunity to connect one-on-one with your audience, and it requires an audio processor that delivers an experience they not only hear, but feel.

Omnia XII, the new flagship processor from Frank Foti and the Omnia team, is the culmination of decades of experience, ratings-proven success, and fresh ideas that challenge technical and sonic boundaries in a way that impacts your listeners on an emotional level. That’s what we mean when we say that Omnia XII is “built from the soul up.”

Built on a rack-space-friendly 2RU platform, Omnia XII has the look and feel of a traditional hardware processor, complete with analog, AES3, and composite I/O alongside Livewire+ AES67 and the redundant AoIP network capabilities required in a modern broadcast facility. But beyond the metal, Omnia XII has the design flexibility and ample horsepower to allow performance enhancements and new features, and quickly respond to emerging tech and evolving standards - all without the need for new hardware. The processor you choose now is just as performant and relevant in the future as it is today.

Sonically, Omnia XII’s all-new processing algorithms employ an intelligent Wideband AGC + 5-band multiband AGC and compressor + 6-band multiband limiter design, dynamic EQ, and powerful bass management tools that provide everything you need to create your custom sound, from open and relaxed to punchy and loud. Frank Foti’s “Clemenza” final clipper - his cleanest and most musical to date - delivers effortless loudness with no compromise to audio quality.

Omnia XII includes our intuitive QuickTweak system that adjusts multiple, interrelated controls simultaneously, demystifying complex processing for operators of any skill level. As always, processing experts can access the full suite of controls expected in a flagship offering.

ITU-R BS.1770 loudness and MPX power meters combine with built-in diagnostic tools, including a digital oscilloscope and FM spectrum analyzer, to display critical parameters and aid in setup and tuning.

A standard Omnia XII configuration includes processing for one FM/HD-1 signal. A comprehensive RDS encoder is included and supports metadata input from common playout systems. An advanced RDS option supports UECP, AF Method B, and other extended RDS features.

A dedicated insertion point allows external watermark hardware encoders to be introduced at precisely the right point in the signal path for maximum effectiveness. SDK software integrations of Nielsen, Kantar, and Ipsos watermarking are optionally available.

An optional built-in stream receiver supports Super Hi-Fi’s HLS+ streaming technology with up to 24 hours of backup playback capability, as well as metadata to RDS routing.

Audio I/O includes analog, AES3, analog composite, digital composite (Omnia Direct), standard linear MPX over IP, and optional µMPX encoding, along with native Livewire+ AES67 for AoIP. Three independent network interfaces provide HTML5 browser-based remote control and SMPTE 2022-7 support for flexible, seamless redundancy and stream protection, including PTP and PPS time sync protocols.

Relay bypass is provided on AES 1, AES 2, and Composite 1 I/O for failsafe and easy switch-over to backup airchains. Dual independent internal power supplies, a feature-rich built-in backup audio player, and dual software banks for secure updating offer peace of mind for unforeseen events.

Livewire Remote Protocol (LWRP) and opto-isolated hardware GPIO on a rear-panel DB-15 connector combine with Rest API communication to provide remote triggering and control of events and parameters.
