Blinds

Quad VC-Polarizer

OVERVIEW

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.

CONTROLS and I/O

For each of the 4 channels:

• Modulation CV offset.
• Modulation CV attenuverter.
• DC-coupled signal input and control input.
• DC-coupled signal output.

TECHNICAL CHARACTERISTICS

• 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.
• Open-source hardware.
