Topic: Another Digital Noise / Ground Loop Question (Babyface)
Hey guys,
I've spent a fair amount of time already researching this problem and even talking to RME support, with no success.
I am experiencing digital / computer noise when monitoring via TotalMix through the AN 1/2 inputs. The noise responds to my mouse movements and is high pitched. The noise occurs even when the breakout cable is unplugged and I'm simply listening with my headphones. Obviously when I try to record with the AN 1/2 inputs the noise to signal ratio is just completely unacceptable.
I have a very simple setup. It's just the Babyface -> Desktop Computer. I'm using a Corsair CX500M PSU. I don't even have a GPU.
Things I've tried which seemed to work for other people:
- using a PCI-E USB card to plug the Babyface into instead of the native motherboard USB ports
- tinkering with the outlets I'm plugged into - I unplugged everything in my room except the Desktop PC to see if that would affect the noise - I even tried witching from surge protectors to wall outlets to no effect
My next step is to purchase some kind of hum eliminator, if that is recommended.
I did purchase this Babyface used from eBay, so it's not out of the question that there's something wrong with it. I am considering returning it (I have a 30 day warranty) and continue to use my Scarlett 2i2, which gave me none of these problems.
Any ideas?
