Erica Synths - Black Polivoks VCF V2

The Erica Synths - Black Polivoks VCF V2 is one of the most faithful recreations of the Russian Polivoks synth's filter. Built in another Eastern-European country with its fully updated high-quality control interface that takes this old filter concept to the level of more advanced eurorack modules. Improvements were added to the V2 including a much punchier bass sound, better attenuation and smaller width.

The Erica Synths Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth, the Formanta Radio Factory Polivoks.

The original Russian ICs K140UD12 are used in the sound circuit. The manufacturers did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion. The result is a much punchier bass sound and very smooth controls.

Features:

New features were added to the V2 version: smaller width, smoother attenuation and much more bass-heavy sound

Switchable BP/LP modes

Inputs/outputs are protected against over-voltage

Diode protection on reversed power supply

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, the manufacturers did not economise on the module width, they put design and usability first. Big knobs are assigned to functions that make difference in sound. The Erica Black series are a range of modules that together make an entire synthesizer.
