Last night, my friend's mixer died. Line fader and cross fader doesn't work. He felt something was burning inside. I didn't see it yet but he told me that on the beginning just the line faders didn't work he swapped line fader with cross fader and it worked as a line fader for a while but suddenly crossfader died as well. I wonder what happend?? It's quiet cold climat over here (Poland- now it's 5 degrees outside) so maybe the temperature was the case? More details soon. Hopefully that wasn't my mixer (Uffff).
