ES79 - Ring Modulator

The ES79 is unique among ring modulators, for providing a means to smoothly voltage control the index of modulation, from 0% modulation of the signal by the carrier, through to 50% modulation (otherwise known as amplitude modulation) and 100% ring modulation with excellent carrier rejection.

The possibilities are endless for musicians interested in programming subtle changes in harmonic content created through the modulation of two signals by each other.

When not needed as a Ring Modulator, the module offers itself as a spare VCA, fully log-linear like its cousin the ES78 VCA (but not as versatile).
