Doepfer A-143-9 VC Quadrature LFO


Voltage controlled sine-LFO with four separate, phase shifted outputs: 0° (sine), 90° (cosine), 180° (inverted sine) and 270° (inverted cosine). Suitable for FM, cross-fadings, modulations in opposite directions or applications, where a pure sine is needed like oscillator for a frequency shifter.



The frequency can be set with two CVs, a potentiometer and a three-position switch.

The frequency ranges are as follows:

  • switch position H: ca. 30 Hz to 3.5 kHz (up to over 20 kHz via CV)
  • switch position M: ca. 1 Hz to 150 Hz
  • switch position L: ca. 0.1 Hz to 10 Hz (up to several minutes via CV)
