From the project

Open source 3.5 to 1/4" eurorack module with inline passive attenuation

euro-converter is a 12hp eurorack module for interfacing multiple eurorack modular synth signals with traditional audio equipment that wants 1/4" TS inputs. Each of its five channels features an inline potentiometer for attenuating the signal from eurorack-levels to studio-levels. Since euro-converter is completely passive, it also works in reverse to easily bring 1/4" outputs into 3.5mm eurorack-friendly inputs!
