I/O Levels Display

Both input and output levels are displayed in real time. The output bargraphs only indicate the output levels of

the digital and analog XLR outputs and do not indicate composite MPX levels on Omnia-3fm Turbo units. The

bargraphs indicate peak levels below 0 dBFS, which is the absolute maximum level of the internal digital signal

processing. In normal operation with normal program audio, signal level peaks should regularly indicate just

above -15 dBFS and never hit 0 dBFS.

Process Display

The process bargraphs indicate the amount of processing (gain-reduction) of the AGC and Limiter bands in the

Omnia-3. Maximum indicated gain-reduction is 25 dB, which occurs at the bottom of the screen. The bargraphs

also have a GATED indication as determined by the Gate Thresh or Hold Thresh setting for that band.

Note: It is normal for the wideband AGC to “recover” to a platform of 10 dB of gain reduction if it is gated

over a long period of time. Refer to Chapter 7, Editing Presets for more information on interpreting and using

the Processing bargraph display.

Menu Descriptions

This section gives an overview of the menus, sub-menus and parameters. The next chapter (Chapter 3,

Processing Overview) presents an overview of the Omnia-3 processing. Chapter 7, Editing Presets, gives more

information on editing parameters including procedures for editing the factory presets to create your own

custom presets.

Main Menu

This menu has four items in Omnia-3am and Omnia-3net/drm: Audio Processing, Input & Output, Display and

Utility. A fifth item: Stereo Generator is added on the Omnia-3fm Turbo style.

Audio Processing

It is from the Audio Processing sub-menu items—Select Preset and Edit Parameters, that the unit’s processing

power is unleashed. Omnia-3 is equipped with numerous presets that can be selected to instantly configure the

processing. The presets are selected using Select Preset. Selecting Edit Parameters opens up the parameter-

editing sub-menu, which allows any processing parameter to be “fine-tuned” to tailor your processing. Save to

Card as allows the edited preset to be saved to the PC Card as a new User Preset.

Input & Output

This sub-menu provides the Input Levels and Output Levels adjustments for the discrete left and right inputs

and outputs, selection of Input Source (Analog or AES-3), Preemphasis and Deemphasis options (Omnia-3fm

Turbo style only) and Mono Mode options. These are generally “set once” selections or parameters, adjusted

during installation and then generally left alone.
