Katowice

A stereo variable band isolator in 10 HP: it splits a stereo signal into low, mid and high bands, the mid band's centre and width set by knobs and CV, the low and high bands following so the three always sum to the whole signal. Each band passes a VCA set by its slider and CV, its stereo pair out on its own, with a stereo sum of the three. A crossover, parametric EQ, DJ-style kill filter or multiband processor.

Key features

• MID FREQ (160 Hz to 10 kHz) and MID WIDTH (1 to 10 octaves) with their CV inputs (±5 V)
• LOW, MID and HIGH sliders with their band gain CV (±8 V, 8 V opens to 0 dB), red LEDs
• INPUT L / R; HIGH, MID, LOW and SUM stereo outputs
• 24 dB/octave crossovers, soft saturation near 18 Vpp
