Doepfer A-168-1 PWM Module

The Doepfer A-168-1 is a compact and powerful pulse width modulation (PWM) utility for Eurorack modular systems. It takes in triangle or sawtooth waveforms and outputs a corresponding pulse waveform with manually or voltage-controlled pulse width. This makes it the perfect tool for adding PWM to VCOs that lack built-in pulse outputs.

A dedicated CV input allows modulation via LFOs, envelopes, or random sources, offering dynamic, evolving timbres reminiscent of classic analog synthesizers. The onboard LED gives visual feedback on pulse width in real time. An ideal solution for enriching subtractive synthesis patches with depth and movement.
