XAOC Devices Katowice

Stereo three-band crossover with voltage control

10 HP Eurorack module

Katowice is a stereo variable-band isolator that splits audio into three frequency bands (low, mid, high) with voltage-controlled crossover filtering and independent VCAs for each band. It combines the functionality of a crossover network, parametric EQ, and DJ-style kill filter with pristine audio quality and creative modulation possibilities.

Features

  • 24dB/octave crossover filters
  • Voltage-controlled band configuration
  • Three stereo VCA blocks
  • Soft saturation circuit
  • AC-coupled inputs
  • Reverse power protection
