Used Doepfer A-196 PLL Pro Sound Effects Unit

This Doepfer A-196 PLL Eurorack module is a phase locked loop processor designed for creating everything from precise pitch tracking to wild, unpredictable modulation effects. Based on classic PLL circuitry adapted for modular synthesis, it analyzes an incoming signal and generates related control voltages and audio outputs that can lock tightly to a source or deliberately struggle to keep up. The result is a module that comfortably lives somewhere between utility and chaos.

The A-196 is especially loved by experimental patchers for its ability to produce glitchy harmonics, stepped pitch effects, aggressive distortion, and unstable oscillations when pushed. At more restrained settings, it can follow external audio or oscillators in musically useful ways, opening the door to sync like behavior, subharmonics, and complex modulation paths. Doepfer’s implementation stays true to the raw character of PLL circuits, making it a favorite for sound designers who enjoy hands on exploration and controlled unpredictability.

This module has been fully tested in store and is functioning properly. We buy, sell, and trade used gear every day, making it easy to evolve your modular system over time.
