+ | It also includes an input saturation stage that provides smooth saturation with automatic gain compensation. The first two third of the control range add slik-soft arctan based saturation, whereas the last third adds some DC bias error just like in a real class A analog console strip. Input can be trimmed after saturation upon preference thanks to the Trim control. | ||
