This module a voltage controlled version of the NLC Ming Rod.
From the Ming Rod description - This module was developed from a paper by Tom Oberheim, presented at the Audio Engineering Society 1970 convention – A “Ring Modulator” Device for the Performing Musician.
The paper discusses the various types of ring modulators and states the transformers in the well-known diode ring modulator can be replaced with transistors. From pg.2 – The transistors serve as phase inverters for driving opposite sides of the ring. The differential amplifier amplifies the sum and difference frequencies while rejecting the signal and the carrier.
This version replaces the phase balance pots with vactrols, so you can use CV to control the balance of inverted and non-inverted signals fed to the diode ring.
The switch changes which sections are controlled so can be used to get quite a different palette of sounds.
