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 l
evels 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 i
f desired, although more
consistency is achieved when this stage is used.
