Ring Modulator + Frequency Shifter


The Radius is a stereo ring modulator and frequency shifter with pitch tracking and an advanced LFO. It smoothly transitions from ring modulation to frequency shifting, and allows you to choose different frequency ratios for the upper and lower tones for some very unique effects.

A ring modulator multiplies two signals together to create new frequencies that are the sum and difference of the input frequencies. One signal is your instrument, and the other is an internal oscillator.

The Radius can double the sum or difference frequency ratios and adjust their relative levels, and offers a unique set of modulation controls, unlocking a spectrum of timbres beyond traditional ring modulation.
