Voltage Controlled Filter

This 4HP Eurorack module is the first of a series of experimental VCFs that we will be releasing. It is a 1-pole, vactrol-based, totally analog low pass filter with resonance. There is a knob and CV input to adjust the cutoff frequency and a knob to bring in the resonance. When CV is used, the frequency knob sets the maximum cutoff frequency. This is a self-resonating filter, so it can also be used as an oscillator. This prototype version will be sold at a discount due to the knobs polarities being reversed (CW turns the freq and res down, CCW turns them up). Quantities are very limited, so act fast if you want one!
