OMNIA Volt 1RU FM On-Air Broadcast Processor
Omnia VOLT 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!
VOLT 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.
VOLT AM - Is specially designed for the challenges of AM radio. Versatile pre- and post-limiting equalization plus superior narrow and wide-band 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!
VOLT HD PRO - Is purpose-built for HD Radio, DRM, DAB, web streams, and other compressed media, as well as syndicated program and studio productions. Selectable bandwidths and crossover points, plus our exclusive Sensus algorithms, help reduce lossy compression artifacts even at low bitrates. Put it in your syndicated program production chain before the uplink: every episode will be clear, clean, and have consistency listeners can recognize. Super-low latency for processed headphone monitoring applications. Use VOLT HD PRO as a general-purpose processor for, gain control, limiting, and program distribution.
VOLT SG (Stereo Generator) - For use in cases where you want to split your system between the main processor—usually at the station—and a dedicated MPX stereo generator with advanced composite features at the transmitter. VOLT SG can be paired with a VOLT FM, one of our other Omnia processors, or with any other processor from another manufacturer. VOLT SG uniquely features the same “One Louder” embedded pilot as the Omnia 11.
