DoepferA-102 VCF9 Diode Low Pass Filter

Doepfer A-102

Module A-102 is capable of unusual resonance behavior and frequency response thanks to its use of diodes. This incorporation ties resonance and frequency together rather than allowing them to operate separately like other filters. Control-wise, the module features three CV inputs (one with an attenuator), input level control, and resonance control that can be driven to the point of self-oscilaltion.
