Polivoks VCA

Super-enhanced version of the Polivoks VCA. Comes as DIY kit.

Erica Synths super-enhaced Polivoks VCA uses core of two differential opamps from the original Polivoks, but we introduced plenty of improvements to achieve higher dynamic range, better reliability, lower noise, accept higher signal levels, keep consistent behavior, self-tuning of two internal offsets (that had to be manually tuned in ПОЛИВОКС), less susceptibility to radio interference and higher linearity, though the heart of it is kept the same. Nevertheless those, who like extreme experiences, can omit all added elements and use the same PCB (with few extra jumpers) to build 100% authentic Polivoks VCA. The Polivoks VCA has distinctive architecture – two differential opamp based VCAs in series each for LFO and ADSR control signal amplitude independently. Control voltage to attenuation behavior of this VCA is nonlinear and not logarithmic, it is kept authentic to the response of ПОЛИВОКС. As most Erica Synths DIY kits, Polivoks VCA kit as standard includes original Russian ICs K118UD1B.
