The Omnia VOLT HD PRO is a powerhouse in audio processing, designed to cater to the demands of HD Radio, DRM, DAB, web streams, and various other compressed media formats. Let’s delve into its features:


  1. Sensus Processing for Digital Program Streams:
    • Exclusive algorithms predict and mitigate distortion caused by digital compression, enhancing sound quality even at low bitrates.
  2. Switchable Bandwidths:
    • Choose from eight bandwidth options (4 kHz – 24 kHz) to optimize multiband processing frequencies and limit high frequencies for cleaner signals across different distribution mediums.
  3. Crossover System Optimization:
    • The crossover system is fine-tuned for various narrow-band options, ensuring all five bands of processing are utilized effectively within bandwidth constraints for maximum performance.
  4. Look-Ahead Wideband Limiter:
    • Alongside five fully adjustable band limiters, this feature guards against quick transients that could introduce distortion, maintaining a consistent and clean sound.

Additional Specifications:

  • Frequency Response:
    • Users can select flat, 50 µs, or 75 µs pre-emphasis curve within ± 0.50 dB, spanning 30 Hz to 15 kHz.
  • Signal-to-Noise Ratio:
    • Offers superior audio quality with over 95 dB analog and over 120 dB digital signal-to-noise ratio.
  • System Distortion:
    • Maintains distortion levels below 0.01% THD within the 20 Hz – 7.5 kHz range, ensuring pristine audio output.
  • Latency:
    • Nominal latency stands at 16ms with variations depending on I/O selection. A low latency FM version is available with a latency of 10ms.
  • Input / Output:
    • Supports composite output impedance of 75Ω with adjustable levels for each of the two outputs.
  • Analog / Digital Inputs and Outputs:
    • Offers flexibility with options for analog, AES/EBU digital, or Livewire AoIP inputs, and corresponding outputs.
  • Remote Control:
    • Allows for remote monitoring and control via GPI, Ethernet, and SNMP, ensuring ease of operation and maintenance.
  • Electrical/Physical Specifications:
    • Operates within a wide voltage range (100 – 250 VAC, 47-63 Hz) with robust built-in protection features.

Regulatory Compliance:

  • North America:
    • FCC and CE tested and compliant, with UL approved power supply.
  • Europe:
    • Complies with RoHS Directive on hazardous substances in electrical and electronic equipment, ensuring environmental sustainability.

The Omnia VOLT HD PRO stands as a versatile and high-performance audio processor, delivering exceptional sound quality and functionality across various digital platforms.
