XAOC Devices Drezno

8-bit ADC/DAC with binary signal processing

10 HP Eurorack module

Drezno II is an 8-bit analog-to-digital and digital-to-analog converter that forms the input/output front-end of the Leibniz Binary Subsystem. It converts analog signals to streams of 8 parallel binary gates (0-255) and back to analog, enabling radical waveshaping, quantization, and binary signal processing with a distinctly digital, lo-fi character.
