I don't really know the Fousrite Scarlett 2i2, but from what Paul wrote in his very informative post, I think you will still have the same issue. As Paul wrote the headset already has the required preamp but it needs to be powered. This thread has some useful information: https://www.gearslutz.com/board/low-end-...mall-mixer.html
