Module A-102 is a reproduction of the legendary low pass filter design that uses diodes in the filter stage as frequency controlling elements resulting in "strange" resonance behaviour and frequency response as resonance and frequency are not independent from another.
As for the rest the A-102 is identical to the A-120 Moog low pass filter resp. the A-103 (18dB TB303 Filter). I.e. the same controls, inputs and outputs. Only the filter sound is different.
