I use a Sound BlasterX G6 with the Beyerdynamic DT 990 Pro headphones now. I just purchased a GoXLR to use with a Shure SMB7. I am also using a dual PC setup. So far everything seems to be working, but I am not sure how, if it's even possible, to use my SB G6 with the GoXLR setup. Any help would be much appreciated! :) Thanks!
