Doepfer A-121-2v (12dB Multimode Filter, Vintage Edition)


Vintage edition with black faceplate and custom knobs.

The concept of a multimode filter with individual outputs, voltage controllable resonance and a similar name is what this module has in common with the old A-121. However, the core is a different one. Instead of the old CEM3320 circuit the filter known from the desktop synthesizer Dark Energy 2 is used.



  • Frequency range: 10Hz to more than 20kHz
  • Level control at the audio input
  • Two cutoff CV inputs: 1x 1V/octave (FCV1), 1x with attenautor (FCV2)
  • Resonance (Q) is voltage controllable; 1x CV input with attenuator
  • Oscillates at high Q settings
  • Individual outputs for four filter types: low pass, high pass, band pass, notch

Audio input, two cutoff CV inputs, one resonance CV input
Filter outputs: low pass, high pass, band pass, notch
