The DFA-2 is a dual mode and dual slope filter and emulates the familiar low pass filter in 4 pole mode and expands sonic potential by adding a unique designed 6 pole low pass mode and quasi and pass mode.Both filters (A and B) are identical and can be controlled separately and by master inputs for the cutoff (CM A+B). The audio outputs from both filters are combined (LPF A+B and BPF A+B) with dual resonance (peak and offers “formant” shaped sounds in low pass and band pass mode. Filters has an individual audio inputs and additionally combined input (AUDIO A+B).The DFA-2 is characterized by a non-linear transfer function, so-called saturation mode, that is affected by the level strength of the incoming signals. The design quality of LPF’s and new features makes the DFA-2 very flexible and results in qualities, such as:
