Dual Ring Modulator A-114

1. Introduction

Module A-114 (Dual Ring Modulator) contains two

separate

ring modulators

A ring modulator outputs the product (Multiplication X •

Y) of the signals at inputs X and Y. It’s similar to a

VCA, but whereas a VCA only responds to positive

voltages at the inputs (2-quadrant multiplication), the

ring modulator responds to both positive and negative

voltages (4-quadrant multiplication).

The ring modulator thus provides a refinement of

amplitude modulation (AM). Ordinary amplitude modu-

lation will output the original carrier frequency f

well as the two side bands (f

- f

, f

+ f

) for each of

the spectral components of the carrier and modulation

signals - but ring modulation cancels out the carrier

frequencies, and just lets the side-bands pass to the

output (see Fig. 1).

A ring modulator is used for the production of bell-like

sounds, alien voices, or just to produce new timbres.
