Doepfer A-143-1 Quad AD-Generator

The Doepfer A-143-1 Quad AD-Generator is a versatile Eurorack module providing four independent attack-decay envelopes. Each envelope is triggered by a gate or trigger signal and produces a control voltage that rises quickly during the attack phase and then falls during the decay phase, both times adjustable via dedicated controls.

This module is ideal for controlling filters, VCAs, or other modules requiring quick and precise modulation. Its compact design, packing four channels into one module, allows users to create multiple modulation paths simultaneously without occupying excessive rack space.
