Using the Delete Preset and Rename Preset options, existing user presets may be deleted from memory or renamed
as needed. The original factory presets can never be deleted or renamed.

We will discuss the Save Preset, Delete Preset, Rename Preset and <-Exit options first before delving into the
details of the Adjust Processing menu.

Adjust Processing


This submenu allows changes to be made in any of the Omnia.ONE’s several dozen processing parameters. These
adjustments alter the sound and texture of the audio.

<-Exit

Click on this option to return to the Processing menu.

Pre-processing

HPF (High Pass Filter)

The high pass (low cut) filter allows you to remove subsonic energy from the input audio prior to
further processing. In so doing, intermodulation distortion performance of the processor and the
audio path following it are improved, and processing resources are not wasted processing
inaudible sounds that have no acoustically relevant information. The filter is third-order (18 dB
per octave) below selectable frequencies of 20, 30, 40, 50 or 60 Hz. It can also be bypassed (not
recommended).

Phase Rot (Phase Rotator)

The phase rotator improves waveform symmetry for program material that is highly asymmetrical
in nature. Examples of such programming are the human voice, and sources with non-sinusoidal
waveforms such as certain string and wind instruments, as well as certain sounds created by
electronic synthesizers. By removing waveform asymmetry from the input program material,
cleaner processing results because any limiting that occurs is able to work equally on both positive
and negative excursions of the audio waveform.

Wideband AGC (Automatic Gain Control)


The wideband AGC rides the incoming audio levels like an automatic “hand on the fader”, keeping the average level
more consistent for the following 4-Band AGC stage, enabling it to stay in its “sweet spot”.

WB AGC (Bypass, Engage)

The wideband Automatic Gain Control (AGC) stage can be bypassed if desired, although more
consistency is achieved when this stage is used.

AGC Drv (AGC Drive)


This control adjusts the amount of drive to the wideband AGC stage. Increasing the drive causes

deeper compression to be achieved, and deeper compression allows quieter passages in the input

audio to be raised further than if lesser drive (and less compression) was used.
