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 fC as
well as the two side bands (fC - fM, fC + fM) 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.

Sockets ! and " are the signal inputs for the A-114.
Patch the signals you would like to ring modulate into
these sockets.
The inputs need to have AC signals - so you should
use audio signals, not control voltages. For control
voltages, use a VCA.

Basic ring modulation
Fig. 1 shows a basic form of ring modulation using two
sine waves. This patch can provide bell- and vibes -
like sounds.
