i bought in december 2 akg mics (c 3000b & c 1000s) from a dude that's selling his whole gear (he plans to move in states) and i trust him he sold me a pair of alesis m1 active mkII and a midi kb Fatar sl 880. BUT these 2 mics seem to distort everytime i work with a stronger voice (even thought in mixer gain is at the lowest level). I use a soundcraft spirit studio lc .
Any idea why ?
