Express Checkout


The Doepfer A-121-3 Slimline VCF is a 12dB multimode filter that packs an enormous amount of functionality into a minuscule 4hp, based on the earlier A-121-2. 

The module features four simultaneous outputs for low-pass, high-pass, band-pass, and notch filtering.

Two CV inputs affect the Cutoff value, and one CV input that controls the filter's resonance.

This makes the A-121-3 a perfect utility filter, occupying minimal space but maintaining robust functionality!
