Polivoks VCF PCB/Panel

Erica Synths presents the most authentic sounding Polivoks VCF emulation available.

This is for a PCB/Panel set (including Russian IC's) in the Eurorack format.

Availability: In stock




This is the most authentic sounding Polivoks VCF emulation available. The original Russian ICs K140UD12 are used in the sound circuit. Erica Synths did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs with gain adjustment option, extended Cutoff knob range and optional resistors to adjust the pot curve, eliminated clicks when switching filter modes, and an output stage was added to eliminate signal inversion as in the original VCF. Result - much more bassy sound, smoother controls.
