Koszalin

A stereo frequency shifter in 10 HP, two inputs and four outputs: it moves every component of a signal's spectrum by the same number of hertz, up and down at once, for atonal, bell-like and barber-pole sounds, with exponential and linear through-zero FM and full stereo feedback under voltage control. A DSP behind an analog interface.

Key features

• SHIFT, its scale stretched round 0 Hz, and RANGE: X1 (±50 Hz), X10 (±500 Hz), X100 (±5 kHz)
• EXP FM (±5 V, its sensitivity with RANGE) and LIN TZ FM with its attenuator
• REGEN with its CV, its routing switch DOWN / UP / COMBI, DENSITY with its CV
• INPUT L / R with the INPUT INDICATOR lamp; DOWN SHIFTED and UP SHIFTED stereo outputs
