Once the desired gain is reached, click the jog-wheel to accept the value and to return to the sub-menu

item. The push-button will conveniently enable you to switch between the parameter adjustment and

the bargraph metering screens.

All of the Omnia-3’s software parameters are set in similar fashion through scrolling through menus and sub-

menus to select which parameter to edit. The parameter choices or values are then selected by rotating the jog-

wheel until the desired setting is displayed. Clicking the jog-wheel selects the parameter value and returns to the

menu or sub-menu item.

Note: Changing the parameter value affects the audio output in real time so that the changes can be auditioned

immediately.

User Interface Concepts

This section introduces you to several important concepts needed to understand and use the Omnia-3.

Presets

Each processor comes with processing presets designed for that style to cover most broadcasting formats or

netcasting applications. A preset contains the saved values for every parameter listed under the Audio

Processing menu for that style. When a preset is loaded, these values configure the Omnia-3’s processing.

The factory presets can be used as-is by loading them using Select Preset, or they can be used as a starting point

to tailor the processing for a specific requirement. Any of the presets parameters can be edited (using Edit

Parameters) to obtain the desired sound. The edited preset can then be saved to the PC Card as a User Preset

(using Save to Card as) and selected just like the factory presets. Editing presets is covered in detail in Chapter

7, Editing Presets

Presets can be backed up to your computer using the free Remote Control software available for download at

www.omniaaudio.com

. Full information about Remote Control is covered in Chapter 8.

System Parameters

System Parameters are any parameters that are not part of a processing preset. These include all settings in the

Input & Output and Stereo Generator menus as well as other system settings such as Dayparts and Trigger

Scripts. Such parameters are typically set once and left alone, and having them change when a new preset is

selected would be undesirable. These are stored in a battery-backed NVRAM chip on the motherboard. If an

event should occur that clears the NVRAM (such as a power outage combined with a dead battery etc.), the unit

restarts using the last saved set of System Parameters stored on the PC card. This means all Input & Output and

Stereo Generator settings are restored from the PC card, as well as other system settings such as any Dayparts

and Trigger Scripts. Also, the preset that was running when the system was saved to the card is stored there as

the default preset.
