    CHAPTER 2 | Omnia VOLT is a lot of processor. We couldn’t put all of it into an introductory, quick-start chapter. To learn all it can do for you, you’ll have to read the rest of this book. (If you don’t have enough time to do that, at least scan the table of contents, and see which chapters will be most useful.)

    VOLT from the studio. But if you’re planning to locate VOLT at the station and feed Left / Right audio (with no sub- carrier) to a transmitter via STL, make sure the STL is linear, and does not use data reduction or compression.

  • Page 17: Hookup

    Do not block the ventilation holes on VOLT’s back. ♦ There’s a lot of electronics in VOLT’s chassis, so it has to be fairly deep: about 11½” plus con- nectors. While it’s not particularly heavy, that depth has to be cantilevered by the one-unit front panel: To prevent damage to the front panel, always mount with four rack screws.
  • Page 18 CHAPTER 3 | Insert Point Normally, all of VOLT’s audio outputs will carry the fully processed output. You can use them to distribute analog to nearby monitors, for example, while sending digital audio to a control room via AES/EBU or Livewire.

  • Page 21: Power Connector

    CHAPTER 3 | Power Connector VOLT automatically adapts to 50 or 60 Hz power at any voltage between 90 – 240 VAC. Nom- inal power is 1A at 110 V, .5A at 240 V. Actual consumption is around 15 watts during normal operation.

    Front Panel and LCD You can get VOLT operational, select a preset, and flexibly adjust it for your station’s sound and market …in minutes… entirely from the front panel!

    CHAPTER 4 | How are they listening? You can use headphones to verify signals or as a rough check on VOLT’s processing. But we don’t recommend using phones for fine-tuning your station’s sound… In our experience, dynamics per- ceived through headphones are different from those heard over speakers, and adjustments made over headphones may be too subtle for loudspeaker use.

  • Page 28 FRONT PANEL AND LCD CHAPTER 4 | In this manual, entering a submenu is identified with a > symbol. So if you see a line like “To send a test tone to the output, go to Input/Output > Output > Tone Gen,” it means “Select Input/Output on the main menu, tap the Jog Wheel, then select Output on the submenu that appears, tap the Jog Wheel, then select and tap Tone Gen”.

  • Page 29: Browser-Based Remote Control

    VOLT can be controlled from a network-connected computer, tablet, or smart phone. Login is password-protected for security. The Remote Control works in real-time. You can read all of VOLT’s front-panel meter (with greater resolution than is possible with front-panel LEDs), and you can hear the results as you change processing settings.
  • Page 30 VOLT uses HTML5, without Java or other plug-ins. Any modern browser should be able to access it from a computer, tablet, or smart phone. Log in by entering VOLT’s IP address in the browser’s address bar. Just the four numbers, separated by periods, are necessary. This will take you to a password entry page.
  • Page 31 Time Out! If you spend a while visiting other sites or doing other computer operations, VOLT’s connection may time out. This is a security feature. You can re-establish your connection by entering the password again. Since VOLT responds to the Remote Control in real-time, nothing gets lost if the connection is dropped.

    CHAPTER 5 | Remote Screen Omnia VOLT’s Remote Screen is designed to let you monitor every important behavior in one place, and access every parameter with just a couple of intuitive clicks. The screen changes slightly with different DSP|Core firmware, but the arrangement and control scheme stays the same.
  • Page 33 BROWSER-BASED REMOTE CONTROL CHAPTER 5 | The four pairs of meters on the left—showing mostly green bars—are stereo audio level meters. They follow normal conventions for peak hold and color coding, and are calibrated 0 to -36 dBFS. These are levels at the processor, so they’re affected by individual level and channel balance controls.

Decide which is closest to the sound you want, and use that as a starting point. Many users like to play with VOLT in their shop before racking it: they feed typical program material, try the controls, and audition all the presets.
  • Page 38 In many cases, QuickTweak will give you the sound you want. With some formats and markets, you might want to get a bit deeper. VOLT has more than 140 routing and processing settings. Feel free to explore all of them in your search for sonic perfection.

    CHAPTER 6 | VOLT Processing Terminology Most of VOLT’s controls are labeled with standard studio or processing definitions, and should be intuitive to any engineer. But a few names are our own invention… because they’re con- trolling algorithms of our own invention. Here’s a glossary of those terms:...
