The Doepfer A-130 is a classic linear voltage-controlled amplifier designed for both audio and control voltage (CV) processing. With its clean and simple architecture, the A-130 is an excellent utility VCA that belongs in every Eurorack system.

Equipped with two audio inputs, each featuring its own attenuator, the A-130 also functions as a basic mixer before applying gain. Its linear response makes it particularly well-suited for use with CV sources, ensuring accurate modulation without curve distortion. That said, it still performs well with audio signals, especially when paired with exponential or logarithmic envelopes.

Manual gain and output level controls give you hands-on shaping of your signal, while the CV input with dedicated attenuator offers dynamic control. The A-130 can process both positive and negative voltages, offering additional flexibility for experimental modulation and audio shaping.

A solid, no-frills utility VCA at an affordable price point.
