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.

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.

AGC Att (AGC Attack)

The attack control adjusts how fast the AGC responds to sudden increases in audio level, and

higher numbers equate to faster response times. Faster attack times reduce the transient nature of

the input audio, while slower attack times improve it. Extremely slow attack times must be used

with caution because allowances must be made in later stages to not overload them during the time

when the broadband AGC is adjusting the level downwards.
