Omnia.11 Broadcast Audio Processor

Omnia.11 Broadcast Audio Processor

Not just the next step forward in FM processing… the Omnia.11 is the result of a complete re-thinking and re-engineering of all aspects of the modern FM audio processor. From the very beginning, the developers of the Omnia.11 were determined to create a processor which would stand head and shoulders above the legendary Omnia 06. So, Team Omnia started with a fresh canvas.

Everything from the firmware platform, the GUI, to every algorithm was re-thought, and in most cases completely re-engineered or re-designed. The result is unlike any existing product of its kind to date. Omnia.11 has literally defined the new state-of-the-art for FM audio processing, as evidenced by a trifecta of awards from the three leading industry publications: 2010 Cool Stuff Award from Radio World Magazine2010 Pick Hit from Radio Magazine2010 TechInk Award for Innovation by Radio Ink Magazine.

For the first time, listeners will hear the programming, not the processor. Effortlessly loud. Thunderous bottom end, sparkling highs, and crisp, clear voice reproduction. All with that trademark punch and clarity which made Omnia the required audio processor of the highest-rated radio stations in the world.

So dramatic is the advancement of Omnia.11, that initial tests have revealed that many early adopters were genuinely startled by the lack of a traditional “processor sound” when the unit was first deployed. The low level distortion and artifacts, long accepted as part of the fundamentals of processing, are now almost completely gone and certainly not perceptible to the ear.

The firmware in Omnia.11 takes advantage of software capabilities never before possible. The results are dynamics algorithms that were once only a dream of the processing enthusiast. AGCs, Compressors, and Limiters analyze music in real time and adjust internal parameters for optimum performance across a broad range of material.

Available in two models:

Omnia FMHD: Featuring dual, independently controlled processing paths for FM and HD/DRM
Omnia FM: Without HD/DRM capability, but can be upgraded to FMHD at a later date.

NEW! G-Force™ Dynamics Engine

The G-Force Plug-In (which ships standard on all new Omnia.11 units and can be added as an optional upgrade for existing units in the field) enables Omnia.11 to handle rapidly changing, hyper-compressed source material better than ever with new, sophisticated improvements. The G-Force dynamics processing framework lets the Omnia.11 set the overall EQ for signature consistency, making it sound cleaner, clearer, louder, more consistent, more open, and more pleasing. You hear the music. You hear the voice. You don’t hear the processor.

Solar Plexus

For deep, tight bass that you can feel!

1 Louder

To gain that extra db of loudness.

Intelligent Ultra-Multiband Limiter System

Self-adjusting attack/release functions guarantee crystal clear music and voice. The limiters are self-adapting and can tune themselves to the activity of the AGC section on the fly, providing more powerful and transparent limiter action than possible before. Makes adjustment of limiters a breeze!

Bass Management

Manages harmonics for a natural and undistorted bottom end.

Ultra LoIMD Distortion Controlled Clipper System

Dramatically reduces intermodulation distortion (IMD) for more loudness headroom.

MPX Composite Baseband Over AES (Omnia Direct)

Output of the Omnia.11’s stereo generator can be coupled directly to the modulator of the transmitter’s exciter. This enables the exciter to modulate with more precision and clarity.

Perfect Declipper Plug-In (Optional)

A revolutionary new algorithm to restore clipped segments and remove distortion in aggressively mastered audio recordings results in a clearer, more open texture that also gives more flexibly with processing choices. (Must be running v3.0 and G-Force.)

SSBSC Technology

Omnia.11 Single Sideband Suppressed Carrier (SSBSC) technology may reduce multipath distortion.

Extra Wide Touchscreen

10.5″ diagonal screen clearly shows all controls.
