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
