Hey all. I’m new here. First post. I bought the UR44 after much research and I am very happy with the device, for the most part. I love the i/o options. The mic pre’s are great, very low noise. My problem is with the line-in for 1 and 2. I suspect I’m getting ground loop noise and I don’t know what to do about it. I’ve tried going into other rooms, and using a ground lift plug, turning lights on and what-not. It’s not making a difference and it’s bugging me. I really hope it’s a ground loop issue and not hardware.
Is there a sure-fire way to test that it isn’t hardware?
If it is a ground loop issue, do you have suggestions about how to fix it?
