Doepfer A-104 Eurorack Trautonium Formant Filter

TheDoepfer A-104 Trautonium Formant Filter is a fourfold filter array derived from the filter circuit found in the Mixtur-Trautonium.


A104 uses four 12dB dual-mode formant filters, with a single audio input and a single audio output. More of a resonance processor and enhancer than a filter, this style of filter circuit excels at making vocal timbres.


The input stages of each of filter modules is far more sensitive than a standard VCO, each filter can run into distortion separately allowing for some unique frequency focused saturation.


The Mixtur was known for it's vowel style voicing and its filter circuit was at the heart of that tone, with an A-104 and a few other choice modules you can own a complete bespoke Trautonium.


The main features of the Doepfer A-104 Trautonium Formant Filter include


Four fold multi-mode resonant filter bank


Circuitry inspired by the mixtaur trautonium


Each stage can run into overdrive, creating new and unexpected effets


20HP wide


Requires 30mA
