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
