The Proc screen includes meters that display activity at various stages of the Omnia XII processing chain.

Wideband: Displays the overall input level and gain reduction in the wideband AGC stage.

ST ENH (Stereo Enhancer): Displays activity in the stereo enhancement stage.

Multiband AGC: Displays gain reduction for each of the five frequency bands in the multiband AGC stage.

Multiband Compressor: Displays gain reduction for each frequency band in the multiband compressor stage.

Multiband Limiter: Displays activity in the multiband limiter stage for the individual frequency bands.

Bass Clipper: Displays activity in the bass clipping stage.

Clipper: Displays activity in the main clipping stage.

Final Limiter: Displays activity in the final limiter stage.

Sensus: Displays activity in the Sensus processing stage.

Proc Screen Header and Processing View Options

The Proc screen provides three views for working with Omnia XII processing: Presets, Quick (Quick Tweak), and Expanded.

Presets

The Presets middle panel lists the available factory and user presets.

Current Preset: Displays the currently selected preset.

Floppy Disk Icon: When hovered over, displays user presets and preset commands:

• User Presets: List of available user presets.

• Save As…: Opens a dialog for saving the current preset as a user preset. Enter a name in the Preset Name field and, optionally, add notes in the Notes field.

• Import: Opens a file-selection dialog for importing a previously exported Omnia XII user preset.

• Export: Exports the selected user preset as a .json file to your computer’s configured download location.

• Trash Can: Opens the Delete dialog for deleting a user preset.

Monitor

• Drop-down menu: Selects the point in the Omnia XII signal path used for monitoring. Options include:

  • FM Output: The fully processed, final audio signal designated for the FM transmitter analog air-chain. It includes final multiband limiting, pre-emphasis, and the effects of the FM clipper.

  • HD Output: The final processed audio signal meant for the digital HD Radio/DAB or streaming air-chain. Because digital codecs do not use pre-emphasis and are highly sensitive to clipping distortion, this path bypasses the FM pre-emphasis and final clipper, routing instead through the dedicated HD final limiter.

  • PreProc Out: The raw audio directly after initial input gain stages, and before any core leveling or automatic gain control occurs. Because it strips away the processing, monitoring this point acts as an operational bypass control to evaluate the untouched input source audio.

  • WBAGC Out: Audio tapped immediately after the Wideband Automatic Gain Control stage. This is the first level-leveling stage that smoothly rides long-term input variations before splitting the audio into separate frequency bands

  • MBAGC Out: The collective, blended output of the five-band Multiband Automatic Gain Control. This lets you hear the combined effect of all five frequency compressors balancing out the overall texture and spectral consistency of the program material before it enters the final peak limiters

  • MBAGC Out B1: This option taps exclusively Band 1, which handles the lowest frequencies (Sub-Bass / Heavy Bass).

  • MBAGC Out B2: This option taps exclusively Band 2, which governs the Mid-Bass / Lower Midrange frequencies.

  • MBAGC Out B3: This option taps exclusively Band 3, which governs the critical Midrange frequencies (where human speech and primary vocal presence reside).

• Level fader: Adjusts the Monitor level. Click and drag the fader to the left to decrease the level or to the right to increase it.

• Level field: Sets the Monitor level. Click the field, enter a value, and press Enter.

Omnia Factory Presets: Provides a list of the available factory presets, organized into three groups: 75μs, 50μs, and None. Scroll through the list using the scrollbar or mouse wheel, or use Search to find a preset.

Search: Searches the preset list. Enter the beginning of a preset name in the Search field.  Search filters the list as you type.

Presets, Quick (Quick Tweak), and Expanded: Selects the processing view.

Quick (Quick Tweak)

Quick Tweak groups commonly adjusted Omnia XII processing controls into two pages:

• Overall: Loudness, Bass, Midrange, and Treble.

• Enhancers: Stereo Enhancement and Bass EFX.

Quick Middle Panel

The middle panel includes the shared preset and Monitor labels and controls described in the Presets section.

Overall Controls

The Quick Tweak Overall page provides broad adjustments to the station’s sound through the Loudness, Bass, Midrange, and Treble controls. These controls affect multiple aspects of the processing rather than functioning as conventional, single-band EQ controls.

A setting of 0% add no additional processing. Use higher settings judiciously, as excessive adjustments may increase limiting or clipping..

Loudness

Midrange

• Overall: Adjusts the prominence of the midrange, affecting the perceived presence and balance of vocals and other midrange content.

Treble

• Presence: Adjusts the perceived presence and articulation of program material.

• Brightness: Adjusts the brightness and high-frequency character of the sound.

• Sparkle: Adjusts the uppermost high-frequency character of the sound. Use this control judiciously to avoid an overly bright or fatiguing result.
