Dual Ring Modulator

Pure sounding bell, gong and block sounds and even "alien" voices.
This is a compact Dual Ring Modulator (4 quadrant multiplier) for your Eurorack modular synth. Fully built, calibrated and tested.

  • A tiny, low cost module, leaving you with funds and space for more comprehensive modules.
  • Outputs the product of the two inputs X and Y
  • Two independent modulators for advanced effects
  • High quality Switchcraft 3.5mm jacks
  • 10 pin Eurorack keyed header
  • Fits in a 4HP wide rack space.
  • Hand built in the USA.

To get started with this module, run a 200Hz sine wave directly from a VCO into the Y input and another sine wave into the X input from a Keyboard/VCO/ADSR/VCA patch. Patch the output to your mixer or output module and play notes on the keyboard while adjusting the tuning of the two VCOs. Then you can experiment with other waveforms and patches.
