More information on each of these processing stages can be found below in the descriptions for each processing
parameter control.
Increasing any setting will lead to more aggressive processing. For example, a higher drive setting adds more gain
into the dynamics section, a higher attack or release setting means a faster time constant, a higher gate threshold
setting means more gating will occur, and a higher (farther to the right on the control) setting for a filter means more
filtering is occurring (so the lowest frequency settings for a low pass filter are farthest to the right on the control).
Depending on the type of control adjusted and its range, the changes you make can affect the sound in subtle or
extreme ways. Our advice is to make a limited number of changes at a time, make those changes in small
increments, and then listen to the results for a period of time before making any further adjustments. Keep in mind
that should you get “lost” you can always go back to where you started by simply recalling the factory preset that
you started with. The factory presets cannot be overwritten.

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.
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.
