I'm having an issue where when I listen to my mic there is a really annoying whining noise. This noise is louder when I listen to my main mic, but is still there when I listen to the mic that is on my headset. Its not as loud on my headset mic but is there. My main mic is a Shure sm7b plugged into a presonus Audiobox USB, when I unplug the mic and listen to just the audiobox its still there. So Iv come the the conclusion that its at least not the mic. Any help would be appreciated.
Iv uploaded the noise here for you to know what I'm talking about: https://vocaroo.com/i/s1O1HXDICLlc
