Blinds Quad Polarizer - 12HP


Blinds is very similar to Mutable Instruments' module Veils, but provides slightly different functions. Polarizers allow one to change the center voltage of a signal, turning bi-polar signals into unipolar signals. When the signal is flipped over the x-axis, it is inverted, providing an 180 degree phase shifted version out of the output. If a unipolar CV signal is fed into the CV input, it will act as a normal VCA. The perk of accepting bi-polar CV signals turns this module into a quad ring modulator, provided they are in audio rate. Each of the outputs are chained together, providing a mix output from the fourth channel. It's time to open the Blinds to let more light through. 


  • 4 Channel Polarizer / Bi-polar VCA
  • Doubles as Quad Ring Modulator
  • All inputs DC-coupled
  • All inputs handle audio-rate signals
  • Input impedance: 100k for all inputs
  • CV offset range: +/- 5V
  • Gain scale: linear, a +5V CV translates to a gain of 1
  • Gain range: +/- 2
