The ADDAC604 from ADDAC System is a multi-mode filter module capable of being used in either dual mono or stereo scenarios. Great for having two filters in one, complex filtering, or even stereo magic, the ADDAC604 offers complete control over each filter's cutoff, resonance, and even CV input with attenuverter to control the cutoff frequency. Each filter has a highpass, bandpass, and lowpass output for utilizing different sections of your sources frequency content, and mixing up the filter outputs on each channel while ADDAC604 is in stereo mode can create interesting textures while sharing a cutoff frequency. Additionally while in stereo mode, you can fix a rear jumper to make the right cutoff control act as an offset for even further complexity. The ADDAC604 offers immense amounts of sonic possibilities in the realm of filtering with flexible control, routing, and timbre.
