Four Quadrant Multiplying Modulator (aka “Ring Mod”)

Out of stock

Category:

A versatile and highly useful ring modulator designed by David G. Dixon.

  • Dedicated ac and dc inputs (all four can be used at the same time).
  • Attenuators for x and y input groups.
  • Polarity switches for x and y inputs (positive, negative or both).
  • Unique ‘q’ control which stands for “quadrant” which allows you to shift the multiplication into positive or negative quadrants.
  • Very low leakage from x input (when q is in center).
  • Changing the q value in fm adds the signal frequencies back into the sum difference frequencies (typical output of a rigmod) which adds richness to the classic ringmod sound and allows for many variations of bell tones, chimes and mallet-type timbres.
  • Can be used as a linear vca.
  • Great for waveshaping (especially two synced audio sources).
  • Excellent for cv mangling (use the dc inputs and play with the rectifier switches).
  • Connecting cv sources to the ac inputs results in interesting lag effects.
