Topic: New Fireface UC! But what is this noise on Mic 1?
I bought a Fireface UC, installed with new firmware and drivers, and took it for a test drive, plugging my Shure SM7 into mic preamp 1.
As I dialed the gain up to about 50 in TotalMix, I noticed a high-pitched whine in Mic 1 that can't be heard on the other input (Mic 2).
Here is a group-normalized recording of Mic 2 (for reference), followed by the whine in Mic 1: http://soundcloud.com/jongrand/highpitch-rme-uc-mic1
All output/inputs to my UC are balanced. Using it with a Mac Pro 4,1.
Please help! I hope it's just some RF issue of coincidence with mic/cable/input 1. If I got ANOTHER faulty unit, after so many years getting different interfaces with different issues, I'll completely lose faith in all these audio brands. How could RME miss something like this in QC? And why me - again?
