So, I recently purchased an AT2020 XLR microphone and paired it with an ISK UMP-1 phantom power unit, which connects to my pc using USB 2.0 cable. Out of the box, I put it through recording tests. in each recording, there is a buzzing in the background of the recording. I have replaced the USB 2.0 going from my power supply into my PC with another identical one. and it made it significantly worse. Do I need a microphone grade USB cable or something? thanks in advance for help on this topic.
attached is a recording of the noise it is making
