Omnia 2001-00439-000 Omnia VOLT Audio Processor for FM

Killer Omnia FM sound featuring 6 AGC sections (5 multiband + wide-band), 5-band, time-aligned limiters, Dynamics Engine architecture, the latest low distortion clipper design by Frank Foti, and a high-quality composite stereo generator. Dozens of modern presets give you an awesome sound straight out of the box. Run studio side to feed your STL, or generate FM composite at the transmitter.

Features:
– 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.
