Description

Doepfer's diode ladder low pass filter: diodes set the frequency in the filter stages, so resonance and frequency are not independent of each other, which gives it its particular resonance and response. Controls, inputs and outputs are those of the A-120 and the A-103; only the sound differs.

Key features

  • Diode ladder low pass filter (VCF9)
  • Cutoff frequency set by hand (Frq.) and by three CV inputs, CV2 and CV3 with their attenuators
  • Audio input with its level control (Lev.)
  • Resonance (Res.) up to self-oscillation, depending on the frequency setting
