DOEPFER A-114 Dual Ring Modulator

The DOEPFER A-114 is a Dual Ring Modulator containing two separate ring modulators, perfect for the production of bell-like sounds, alien voices, or simply to produce new timbres in your sound design journey.

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 modulation 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.

Key Features:

• Dual ring mod for classic synthesizer timbres
• Doubles as a dual VCA when fed only positive modulation signals
• Compact Size
