DoepferA-120 VCF1 24dB Low Pass Filter

Doepfer A-120

The A-120 module was inspired by the classic Moog low-pass transistor cascade filter. The module features a 24dB slope and three separate CV inputs, each with potentiometers, that control the cutoff frequency. The audio input also has a dedicated potentiometer that can be used to overdrive the filter.
