Blinds is a 4-channel voltage-controlled signal polarizer - bipolar VCAs

Each channel consists of a polarizer circuit, also known as a four-quadrant multiplier. This circuit acts like a VCA, except that a negative control voltage will cause the output signal to be inverted, instead of being silenced.

Blinds’ outputs are daisy-chained, allowing adjacent groups of 2, 3, or all 4 channels, to be mixed together.

A hub for your modulations

  • Scale, invert and offset up to four modulation signals.
  • Mix up to four CVs or audio sources.
  • Multiply (ring-modulate) two audio sources, with adjustable carrier rejection.
  • “S/he who can do more can do less”: each channel can be used as a plain VCA.
