OMNIA VOLT MULTI-USE AUDIO PROCESSOR FM/AM WIDEBAND AGC/5 BAND AGC/5 BAND LIMITER AES/EBU , AUTOMATIC FAILOVER AND LIVEWIRE AoIP PN 2001-00439-000

Features

VOLT FM 

• A new generation Frank Foti-designed Clipper for stronger on-air sound.

• Flexible Pre-Emphasis Switching. This makes it easy to fit VOLT into any existing FM airchain.

• Dual Variable Composite Outputs to feed a main and backup transmitter.

• Variable Pilot Level and Phase let you fine-tune the signal for transmission.

• Adjustable SCA input for additional services, including RDS and specialty networks.

• 19 kHz sync output to synchronize external generators.

• Bass Pre-Clipper - Fully adjustable with Tightness and Girth controls. You’ll have strong, listener-pleasing bass without worrying about intermodulation distortion.

• Adjustable BS-412 Threshold and Processing for full compliance with ITU standards.

• BS-412 and Low Latency settings that can be turned on as needed. 

• Automatic Mono “Dry Voice” Sensing - Ideal for FM Analog Stereo stations using extreme processing: it keeps an extra hand on the clipper, to stop distortion when the L+R channel gets boosted by mono signals.

• Low Latency FM mode - lets you fine-tune the tradeoffs between processor latency and ultra-high quality.

• Stereo Enhancement for FM Analog, without Adding Multipath - You’ll get a wider, more exciting signal that jumps out of the radio.

• Optional expansion module to support Kantar watermarking.

• MIB2 compliant SNMP support.

VOLT AM

• Extra equalization to control or enhance highs in two critical places, both before and after the multiband limiter.

• Wide and Narrow bandwidth options and presets 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.

FM, AM, and HD-Pro VOLT processors commonly feature:

• Optimized Dynamics Engine and time-aligned crossover system designed by our best Omnia engineers. 

• Six Separate AGC Sections - Tunable midband crossover, one wideband, plus five separate time-aligned narrow band sections, each with separate controls for every important parameter 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.
