Doepfer A-101-8 Photo Phasing

The Doepfer A-101-8 is a fully analog phaser module based on photo-resistive elements, emulating the classic optical phase shifters of the 1970s. With eight phase-shifting stages controlled by light-sensitive components, it offers a warm, flowing modulation character that stands apart from OTA or digital alternatives.

This design yields a smooth and organic sound, perfect for adding subtle motion, psychedelic textures, or slow-evolving modulations to your Eurorack system. Voltage control over phase and feedback adds dynamic movement and expressive performance possibilities.

Key Features:

• Fully analog, photo-based phaser module

• 8 optical phase-shift stages

• CV control of phase and feedback

• Rich, vintage-style sound

• Ideal for ambient, psychedelic, and experimental patches
