Module A-101-8 is a 8-stage phase shifter which uses light-sensitive resistors (LDR) and is a replica of the Compact Phasing A manufactured by the company Schulte in the seventies. The actual phasing circuit is identical to the historic model. Only the illumination control of the LDRs is different: the A-101-8 uses LEDs to illuminate the LDRs, the historic model used incandescent miniature lamps. And the A-101-8 has no built-in LFO but can be controlled by any external control voltage source (e.g. LFO, ADSR, random, Theremin, ribbon controller, sequencer, midi). The phasing offset (i.e. the base value for the phase shifting) and the modulation depth of the external control signal can be adjusted separately. The Compact Phasing A had no offset control but only a depth control for the built-in LFO. Feedback and mixing ratio of the output signal are set by two controls. The audio input is equipped with an attenuator. The module has two audio outputs available (same as the historic model) and a visual display of the phase shifting.

Features
- Control Man. : manual control of the phase shift offset (base value)
- Control CV: attenuator for the signal applied to the CV socket
- Control Feedb.: Feedback or Resonance (similar function as filter resonance/feedback/emphasis)
- Control Mix: sets the mixing ratio between original and phase shift signal appearing at output 1
- Control Input Level: attenuator for signal applied to the In socket
- Socket In: audio input
- Socket CV: control voltage input
- Socket Out 1: audio output 1 (mix signal)
- Socket Out 2: audio output 2 (modified input signal)
- LED: visual control of the phase shift
- The input signal is processed at first by a pre-stage which outputs a "modified" input signal (*). This signal is not processed by the phase shift stages but is affected by the feedback setting. Only when feedback is set to zero this signal is identical to the input signal. Otherwise it contains feedback components.
