The TELOS OMNIA VOLT : BROADCAST AUDIO PROCESSOR offers “best in class” processing performance 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. With thousands of units on the air, VOLT gives you more sonic performance and processing power in one rack unit than others give you in three. Now with new Version 2.0, the best just got better.

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.

VOLT HD PRO

• Sensus® Processing for Digital Program Streams - Omnia’s exclusive Sensus algorithms predict how HD, DRM, DAB, or streaming data reduction will affect your sound. They precondition your signal, making digital compression sound better—even at low bitrates, actually reducing the distortion added by psychoacoustic compression schemes.

•  Switchable bandwidths with eight choices between 4 kHz – 24 kHz. They reconfigure VOLT’s multiband processing frequencies as well as limit high frequencies, to give you the cleanest signal for your distribution medium.

• 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.

• Look-ahead wideband limiter in addition to five fully adjustable band limiters guard against quick transients that can add distortion.

VOLT SG

• SSBSC support lets you select Single Sideband suppressed carrier for more multipath immunity, less noise, and more robust HD radio.

• “One Louder” technology embeds the stereo pilot directly into the composite signal. This frees up power, giving you a full decibel more loudness—effectively, 10% additional modulation—without exceeding legal limits.

• Flexible Composite Limiter can be calibrated to control overshoots from nonlinearities in your STL.

• Pilot Phase adjustment of ±32°, compared to the 38 kHz suppressed carrier, to compensate for timing errors elsewhere in your system.

• Advanced single sideband suppressed carrier processing [SSBSC] - for reduced multipath and more robust HD transmission.

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.
