The Fixed Filter Bank 914 from AJH Synth is based on the sought after 914 Fixed Filter Bank from the 1960’s Moog 900 series modular synthesiser system. The design was revisited and adapted for eurorack.

The module features twelve fixed frequency, inductor based bandpass filters, from 125 Hz to 5,8 kHz. Additionally it provides low pass and high pass shelf filters. The bands are split to left and right channels. The inbuilt voltage controlled crossfader allows panning between left and right banks, with a mix of all bands available in the central position. Furthermore there is another crossfader which enables blending between the incoming signal at input 1 or 2 and the wet mix output. The biggest addition to the original design is the feedback control.
