Recently I hear a noise sound at my studio around 10-15 Khz, when I'm using EQ the analyzer show there has a 20Khz "stand noise".
How can I find the cause and "kill" the noise sound.
I'm using UPS, TV, PC, UR242.

Hugh, thank you. You've just confirmed something from my youth. That noise drove me absolutely crazy when I was in my early teens, to the point I couldn't bear to be in the same room as the TV (and I knew it was the TV) sometimes.
Problem was, nobody else in my family could hear, or 'tune in' to it, leading to many differences of opinion and me being told I was imagining it.
Ha!

But that was long ago...
