Katowice Stereo Variable-Band Isolator

XAOC Devices Katowice

Katowice from XAOC Devices is a stereo band isolator that isolates and manipulates a selected range of frequencies. It splits incoming stereo signals into low, mid, and high bands. The knobs and associated CV inputs define the frequency and width of the center frequencies. This ranges from 160Hz to up to 10kHz with a width of one to ten octaves.

The low and high frequencies are always automatically adjusted, so the sum of all three signals is equal to the incoming audio. Each band passes into a high-quality VCA with control over the signal's amplitude using the slider and CV inputs. The output of each band and the sum of all three bands post VCA are available as stereo pairs. The first of XAOC's line of stereo devices, Katowice is useful as a band-limiting EQ, crossover network, or DJ-style kill filter under voltage control that fits many niches.
