Doepfer A-104 Quad Resonance Filter subdecay Phantom-powered active electronics provide stableA 104 is a fourfold formant filter as used in the Mixtur Trautonium by Oskar Sala. It is made of four parallel resonance filters, each filter can be switched to low pass or band pass or off. Frequency, resonance and level are controlled for each filter separately (no voltage control). The frequency range for the filters is about 50Hz 5kHz. The filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds if
