Omnia VOLT is the latest triumph from the people who brought you the multiple-award-winning Omnia.11, the acclaimed Omnia.9, the power-packed Omnia 7, and the 13,000+ Omnia ONEs currently in service. VOLT gives you more sonic performance and processing power in one rack unit than others give you in three. Here’s how:

With VOLT, we have rewritten the rules for broadcast DSP, fine-tuning our algorithms and creating the world’s best-sounding, most powerful and versatile 1RU audio processor. The QuickTweak system helps users get just the sound they want quickly. You can get VOLT on the air in minutes, select presets that have been designed for today’s stations and programming, and create a unique sonic personality with just a few nudges.

VOLT may be the most value-packed audio processor on the market, thanks to its DSP|Core firmware module system. This system means you can re-purpose your VOLT to serve different needs by simply updating firmware. The capability to turn your FM VOLT into an AM unit or into an HD/DAB or SG box comes built into every VOLT, and the fact that each DSP|Core firmware package is FREE is like getting 4 processors in one package. Modules include VOLT FM, VOLT AM, VOLT HD PRO and VOLT SG. Each Core has a feature set that has been fine-tuned for its application, optimizing system DSP to the unique demands of different user applications.

VOLT AM - Designed specifically for the challenges of AM radio. Versatile pre- and post-limiting equalization plus superior presets created for today’s AM stations give you the cleanest and most powerful signal on the band. Asymmetrical Modulation and Tilt, applied after the clipper, help you get better performance even from older transmitters!


Extra equalization to control or enhance highs in two critical places, both before and after the multiband limiter.
Wide and Narrow bandwidth options to let you get the best combination of coverage and quality for your station’s format.
Crossover system is re-tuned for various narrow band options so that all five bands of processing are used within the bandwidth constraints for maximum performance at all bandwidth settings.
Adjustable Tilt to compensate for low-frequency ‘droop’ in older plate-modulated transmitters.
Asymmetrical modulation for maximum AM power.
Flexible Pre-Emphasis Switching on audio inputs and outputs. This makes it easy to fit VOLT into any existing AM airchain.
Optimized Dynamics Engine and Time Aligned Crossover System designed by Senior Algorithm Developer Cornelius Gould
Six Separate AGC Sections - One wideband, plus five separate time-aligned narrow band sections, each with separate controls for every important parameter. Plus a tunable midband crossover. Give your station the loudness and consistent sound you want!
Five Separate Time-Aligned Limiter Sections - each with separate Drive, Hold, Threshold, and Attack/ Decay controls. They give you protection against over-modulation while maintaining a loud signature sound.
QuickTweak™ Adjustment System - lets you fine-tune your sound like a processing genius. Get exactly the processing you want in minutes, while you’re on the air, right from the front panel or a connected computer or tablet.
Variable Deep Bass, Phat Bass, and Warmth enhancers - Get that meaty Omnia sound, fine-tuned the way you want.
Clipper Silk Adjustment - (FM & AM) If your format is prone to treble distortion, you can add just enough Silk to clean up those high frequencies.
Variable High-Pass and Switchable Phase Rotator - Special processing in VOLT’s input makes sure that ultra- low frequencies, too low to be perceived as bass by listeners, don’t rob you of on-air power.
Totally Flexible Input / Output - Use analog, AES/EBU digital, or Livewire® AoIP inputs; analog, AES/EBU digital, Livewire, or composite outputs (FM & SG only). Adjust channel balance and correct polarity separately on each input. Save and recall input/output setups for different applications. All outputs are always active, regardless of input type.
Switchable Insert Points for Voltair®, Watermark Encoders, or Other Downstream Encoding - Optimize your airchain and eliminate the need for external pre-processing! You can feed encoders with a pre-processed signal from VOLT’s multiband AGC and limiters so your encoder sees a stronger, more reliable signal. Then feed the encoder’s output back into VOLT, for post-encoding clipping that protects you against overmodulation.
Automatic “Failover” signal switching - Designate a backup input to use if your main signal drops out or STL fails. Switch to this source automatically, with adjustable sensitivity, or trigger it as needed.
Graphic User Interface - is easy to navigate, but gives you the deep level of control you need.
Built-in HTML-5 Server - for full control from any modern browser, tablet, or smartphone… without special plug-ins.
Rugged 1RU Construction - fits any control room, technical center, or transmitter shack, with easy-to see LED meters.
Cool Running, Fanless Operation - VOLT can even be used near live mics.
Flexible Pre-Emphasis Switching - makes it easy to fit VOLT into any airchain.
Built-In Tone Generator - provides for quick setup and calibration.
Multiple Selectable Bandwidths for Digital Data Streams - More than simple low-pass filters, HD Pro also modifies the VOLT’s crossover to get the best results for any bitrate.
