Doepfer A-121SV Stereo Multimode Filter - Vintage 1u modular Introducing SubwayModule A 121s is a dual multimode filter which can be used for stereo applications as well as for parallel or serial organized dual mono filters. The core is a 12dB multimode filter identical to the modules A 121 2 and A 121 3. The selection of the filter type is continuously from lowpass via notch and highpass to bandpass. We attached great importance to the usability of the manual controls and CV inputs for both stereo and dual mono applications.
