Blinds is a 4-channel voltage-controlled signal polarizer. 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. One can think of Blinds’ as a voltage-controlled version of Shades, the control center for all the modulation CVs used in a patch. Many other uses are possible, though. For example, each individual channel can be used to scale/offset a CV; and with audio rate modulation signals, each channel acts like a ring-modulator, with massive potential for drones and feedback patches. Technical characteristics 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. 12-HP. Current consumption: +12V: 70mA ; -12V: 70mA. Open-source hardware. More… User manual
