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.

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.
