I played in the country Sat at a festival. 1.5 hour gig. Helix into frfr from XLR out, then line out into FX return on Carvin V3 pushing 2 V30's. They put a mic on one of the V30's
Everything is good until I suddenly have no sound.... I look at amp/helix/cables (this during the song) all have power. It really caught me off guard. I finally rebooted the Helix and my sound came back. 3 songs later : same thing. I knew what to do this time, and rebooted Helix first thing. I'm concerned about this. both these lockups occurred before the first 1/3 of the set was done. I had no other problem for the final 2/3 of the set. Outside gig - temp was 57F so I know it didnt get hot. We played at 10pm so no sun.
The kicker is: I've played it previously several days in a row at band practice for a longer period of time and no problem. This makes me very uneasy.
Any Ideas?
