Ringmod 1U

Four quadrant multiplier / active DC coupled ring modulator

Ring Modulation is a classic synthesis technique that takes two source waveforms and generates a third waveform, which contains the sum and difference frequencies of the two inputs.

At audio rates, ring modulation creates a fairly inharmonic and ‘metallic’ sound. At LFO rates, ring modulation can generate interesting and complex modulation shapes.


  • Active ring modulator that uses a high-quality SSI2162 VCA IC.
  • DC coupled so it can be used for both CV and audio.
  • Can be used with unipolar control signals as a linear VCA
  • Very compact size
