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.

Ground rules:

• Do NOT ask on the mutable forums or email Mutable Instruments for help.  There is literally ZERO support offered from those channels - don't be an ass.  A number of Facebook groups exist to help with DIY builds, and we're happy to help as well.
• Do NOT (re)sell these, passing them off as factory modules.  Seriously - don't be an ass.
• Do NOT be totally scared of SMT.  If you haven't done it before, it's off-putting, we get it - but give yourself a chance.  Learn something.  That's what (we think) DIY is all about.  We're keeping the prices on these low enough that you can afford to try and fail!
• DO have a ton of fun building them, and use them to create awesome sounds.  Then go buy a Mutable Instruments module and SUPPORT Émilie's designs, directly.
