The other night at my gig. Channels 1 & 3 on my mcx 8000 would not play through the pa, I was able to hear them in the headphones and get a level reader. Soon as brought the x fader the left side, nothing. I was able to use channels 2 & 4, putting channel 4 on the left side, so I could have a smooth transition… more or less . Anyone know what could of caused this? Thank you for your help.
