The two sides of the Z-2 is built around a comparator and a one bit memory that is clocked by the comparator. This is the evaluating click less switching control circuit used in the D-2, 4-Band Distortion module but with all the ins and outs accessible.
The module is DC coupled so it can be used with anything from DC and control signals to audio rate and above audio rate.
