adobe audition - connected xlr to phantom power and power to USB input on windows surface - get high pitched feedback

[talkjak]

hello - i have a microphone that is connected to a phantom power supply via traditional xlr and then an xlr to usb cord going into my windows surface/adobe audition ( also tried a regular voice recording software to ensure it wasn't an audition issue) although i get the input loud and cleaer there is a high pitched "squeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee" in the background and it's highly audible. i changed out the cords and power supply and it didn't work. i also tried adjusting the input on my PC recording device settings but it just adjusts the input overall not and doesn't remove the tinny sound.

any other ideas as to what could be causing this?

What is an XLR to USB cord?

You need some sort of audio interface to go from an XLR mic input to a computer's USB input. It also needs to have a built in mic preamp and that would mean that it probably has a built in phantom power supply as well.

I think that what's absolutely clear about this is that we need to know exactly what device it is that the mic is plugged into, for a start. And does it have any form of monitoring attached to it? The fact that you've called it a 'tinny' sound makes me a little suspicious about a monitoring digital feedback loop - that's often the description given for the sort of sound that produces...
