I was just called up to take a look at a QU-32 belonging to a church. The Master fader and the fader controlling mix 5/6 suddenly moves up from unity to the highest position (+10) on their own, no router connected, no QU-pad. This of course causes a loud tweeter screeching. TWO HF drivers are burnt already as a result. QU-32 runs on version 1.90 REV. 4537.
Any solution to this? Is this a firmware issue or a hardware problem? Anyone has this problem too?
Many thanks
