I have a annoying hum in my set up.( a bit like if I put my hand on a live guitar jack humm ) If I turn my headphones level on the 002 rack over half way it is there ,and at full it is annoying. I also have it on my krk5 monitors (which I have set on full volume) ,even if the mute button is on. I have a splitter box to amp and auratone speakers, if I switch to them the hum is gone from the krks to the auratones . ( just in case its relevant). So has anybody else had this prob and is there a process of elimination that I can follow to find if there is a fault . transformer positioning ,power plugs etc . Now that Im writing this the noise is annoying me more, I think I use to block it out and soldier on, but now it is getting in the way of clear recording.
