Question

The device seems rather sensitive to rippled 5V from most USB mains adaptors. Presonus doesn't offer a PSU that I am aware of. Neither do they recommend one. Is there a recommended world wide available brans and type of adaptor with good switch noise free output? .

I am also interested to know this and it relates to my question: https://answers.presonus.com/80855/ground-loop-electrical-noise-with-microstation-bt

have you tried any ground loop isolator devices for your microstation?
