Knobs is a highly playable, precision voltage processing utility.  Two channels of configurable gain, offset, and slur feed a low-noise CV crossfader.  This layout takes useful utility functions and makes them very playable and interactive.


  • Two voltage processing channels
  • Precision attenuversion with range switch for positive, negative, and bipolar gain adjustment.  Control extents provide gains of exactly 0 or +/-1
  • +/- 5V offset adjustment with trimmed 5V precision reference
  • Slur adjustment up to 23 seconds
  • Low noise CV linear crossfader normalled to voltage processing channels
  • 'Smooth detent' fader with precise settability of center position
  • Active switch for bypassing, zeroing, or applying processing
  • RGB voltage indications of signal polarity, amplitude, and zero value
  • Long life switches & potentiometers
  • Low loss, high speed active reverse voltage protection
  • Overcurrent protection
  • Low loss, long life, high rel power cable with keyed & latching connector
  • Extremely high build quality and reliability (click here for details)
