Three parallel, voltage controlled, resonant bandpass filters (each switchable to lowpass per jumper), each with an own LFO or CV input with attenuator. Separate outputs for each filter and a mixed output. Very well suitable for living filtering or as a formant filter with modulation (unlike A-104).
Each bandpass has it's own triangle LFO with adjustable frequency and amplitude ,modulating the cutoff frequency. Instead of the internal LFO an external control voltage may be used. In this case the CV is fed into the external CV jack (with integrated switch to turn off the LFO signal) and the LFO's amplitude control affects the CV modulation intensity instead.
Each filter is equipped with the following controls: LFO frequency, LFO/external CV amplitude, cutiff frequency, resonance and filter amplitude. In addition to the mix output for all three filters each filter has a separate audio output. The original audio signal can be added to the triple filter mix signal with a separate control.
The filters share a common audio input with attenuator. The filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds - if desired.
The frequency control range of the bandpass filters is about 40Hz...6kHz, the frequency range of the LFOs is about 0.02Hz...20Hz (= 1 min ... 1/20 sec per cycle).
Each filter can used also as a 12dB low pass instead of band pass. For this a jumper has to be changed on the according filter board. In this case the module can't be called any longer a "resonance filter" but "triple low pass filter". It is also possible to change the characteristic for only one or two filters, up to you.

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
