Doepfer A-111-2 High-End VCO II

Availability: In stock
Doepfer A-111-2 High-End VCO II is available to buy in increments of 1

Module A-111-2 is the successor of the obsolete High End VCO I A-111-1.


  • triangle core
  • min. 15 octaves pitch range (typ. 0.5Hz - 20kHz)
  • perfect 1V/octave tracking over min. 12 octaves (typ. 5Hz - 20kHz)
  • exponential frequency controls and inputs:
  • Tune (~ 1 octave range)
  • Fine (~ 1 semitone range)
  • Octave (range switch with 6 positions)
  • 1V/octave CV input
  • XFM input with attenuator
  • access to bus CV (via jumper, optional)

linear frequency controls:

  • LF (manual linear frequency control: fully CW = standard setting for usual VCO applications, fully CCW: close to 0Hz frequency)
  • LFM input with attenuator, DC coupled

Pulsewidth controls for rectangle output:

  • PW (manual pulsewidth control from 0%/output = fixed at "low" state up to 100% / output fixed at "high" state)
  • PWM input with attenuator
  • Hard Sync input
  • Soft Sync input

Waveform outputs:

  • Sawtooth
  • Rectangle (with PWM)
  • Triangle
  • Sine

Nearly "perfect" waveforms (no glitches)
high end triangle to sine converter with excellent sine waveshape (thank's to Tim Stinchcombe who recommended this circuit)
