I just landed a fill in sound/ house tech gig. The headliner(they have a touring engineer)is filled with some musicians I idolized as a teen. I will be mixing the opener(b-c level touring act) on the house M32. I have some experience with an x32rack and I own an x18, but have never used a full console. Any tips? Also,as a "house tech" who has only been inside this venue twice what will be expected of me by the touring engineer?
