Fonitronik MH31 VC Modulator Voltage Controlled Ring Mod Module

The VC Modulator is primarily designed to perform Ring Mod effects with expanded control! It's DC Coupled allowing complex CV processing!

At it's core there is a carrier signal that is audible and a modulator section that performs balanced modulation on it, where the carrier is run through a bipolar vca whose level is controlled by the modulator input. Each input has a unipolar VCA that controls it's level, allowing for complex modulation or even for sneaking in a 3rd modulation wave! From Fonitronik:

Contrary to other common Circuits the mixing of Frequencies is realized by using Operational Amplifiers. The result differs audibly from other Ring Modulators and one must not expect classical functions of a Ring Modulator. Here we come into noisy and dirty terrain. Moreover the module is DC-coupled, so it is usable for control voltages, too..

Note: This is a used module. It may exhibit minor signs of wear such as rack rash but is fully functional. This module will include M3 screws, ribbon cable, and a box, but not the original box.
