Does anyone here have any experience with the Shure X2U XLR to USB adapter? My
first one had what sounded like a high frequency oscillation that manifested
itself as a loud hiss. Shure replaced it. I don't know if the old one did this,
but the new one is difficult to set the mic gain correctly. The gain changes
dramatically at the top end of movement of the gain pot. The gain (as viewed in
Audition) goes from -12 to DFS with a very slight movement of the gain control.
I'm using it with a dynamic mic.
