Doepfer A-114 Dual Ring Modulator

The Doepfer A-114 is a dual ring modulator in an 8HP format, offering two independent analog circuits for classic amplitude modulation. Each section features two inputs (X and Y) and a single output (X×Y), producing the mathematical product of the input signals—ideal for generating rich, metallic, or bell-like tones.

The circuits are fully passive and identical, allowing you to modulate two audio or CV pairs simultaneously. This makes the A-114 useful not only for audio-rate effects like clangorous textures and harsh overtones, but also for creating complex modulation signals at low frequencies.

Simple in design but musically powerful, the A-114 brings a classic synthesis technique into a compact and accessible Eurorack format.
