If you are reading this, most probably, you are about to build Erica
Synths DIY Polivoks VCF. This module is 30mm deep, skiff friendly,
has solid mechanical construction and doesn't require wiring.
Polivoks VCF is famous for its' crazy resonance sweeps and deep,
bassy sound which makes it ideal for acid basslines. We believe,
this is one of most is one of most authentic sounding famous
Russian synth Polivoks VCF emulations available. The original
Russian ICs K140UD12 are used in the sound circuit. We did several
updates to adapt the VCF for contemporary modular synth
demands. Independently buffered inputs, extended Cutoff knob
range, eliminated clicks, when switching filter modes, and output
stage added to eliminate signal inversion.
The DIY Polivoks VCF kit comes in three versions:
1) PCB + 2xK140UD12 ICs,
2) PCB + 2xK140UD12 ICs + panel,
3) Full kit.

• Skiff friendly design
SPECIFICATIONS:
• Input level
• CV input level
• Filter modes
• Module width
