XAOC Devices Kamieniec

Analog resonant phase rotator with self-oscillating feedback

9 HP Eurorack module

Kamieniec is an analog 4/6-stage resonant phase rotator inspired by OTA-based phaser pedals of the 1970s, offering simultaneous four-stage and six-stage outputs that can be used as a faux stereo pair. Its feedback circuit can be pushed into self-oscillation, producing sounds ranging from creamy classic phasing to brutal, grinding resonance far beyond typical phasers.

Features

  • Analog 4/6-stage phaser inspired by OTA-based 1970s classic phasers
  • Simultaneous four-stage and six-stage outputs usable as faux stereo pair
  • Four tunable OTA-based allpass stages plus two fixed allpass stages
  • Feedback control capable of self-oscillation at approximately 3/4 knob travel
  • Two resonance modes: WASTED (4-stage feedback) and STONED (6-stage feedback)
  • Switchable feedback polarity via internal jumper (positive default, negative option)
  • Onboard voltage-controlled LFO with triangle waveform, wide range from sub-Hz to ~700Hz
  • Independent LFO output for use as general modulation source (signal amplitude over 8V)
  • External modulation input (EXT MOD) mixed with internal LFO for FREQ control
  • DEPTH knob controls amount of LFO sent to phaser frequency
  • Dedicated LFO RATE CV input for voltage control of LFO speed
  • Daisy-chaining via 3-pin backside headers for multi-stage phasing with additional units

Controls & Jacks (15)

  • LFO RATE— Voltage control input for LFO speed, works in conjunction with RATE knob.
  • EXT MOD 1— Additional external CV input for modulation.
  • INPUT— Main audio input signal to be processed by the phaser.
  • LFO OUT— Independent LFO triangle waveform output. Signal amplitude is over 8V.
  • DEPTH— Determines the depth of LFO modulation applied to the phaser frequency parameter.
  • 6-STAGES OUTPUT— Output with signal mixed after six phase shifting stages, producing a 3-notch frequency response. Can be used as stereo pair with 4-STAGES o
  • FREQ— Tunes the frequency base point for phaser operation. Without modulation, serves as manual cutoff adjustment. Modulated by internal LFO and e
  • RATE— Controls the speed of the internal LFO, indicated by a corresponding LED.
  • 4-STAGES OUTPUT— Output with signal mixed after four phase shifting stages, producing a 2-notch frequency response.
  • EXT MOD 2— External CV control of the frequency tuning point. Mixed with internal LFO unless DEPTH knob is set to zero.
  • RESONANCE MODE— Selects between WASTED and STONED feedback modes, determining whether four or six phaser stages are in the feedback path.
  • RESO— Controls the degree of resonance by adjusting the amount of processed signal fed back into the phase shifter chain. Can cause self-oscillati
  • Reso CV
  • 4 STAGES OUTPUT— Output with signal mixed after four phase shifting stages, producing a 2-notch frequency response.
  • 6 STAGES OUTPUT— Output with signal mixed after six phase shifting stages, producing a 3-notch frequency response. Can be used as stereo pair with 4-STAGES o
