I believe this is what everyone is looking for. “Auto-gain”, of a sort.
The amount of compression applied to the signal. The values to the left half of the knob will affect the Pre – EQ compression, increasing the amount of compression as you move it counter clockwise. The values to the right half of the knob will affect the Post -EQ compression, increasing the amount of compression as you move it clockwise. The compressor is specially designed to vary the numerous parameters of a typical compressor such as the ratio, attack, release and the makeup gain to keep the overall loudness consistent.
Similar to the distortion algorithms’ compression, and remarkably effective. With all of that GAIN & TRIM range, it’d almost have to be adaptive compression, to be on the safe side. The threshold value must be some pre-set level, or levels that depend on the other parameter settings.
