Bose T4s cuts out midstream. Seems to be warm to touch. If I leave it off for 20 minutes It comes back on. If I try it before that it repeats the flashing screen and shuts down again. can it be a heat issue. No good for gigging. My T1 works fine. They are hooked to an L1 mod 2 direct. I run a pedal board direct to the mixer. Also a neuman condensor and a Tascam 24 sd recorder. It’s a relatively new unit although I ‘ve had it awhile. ( I was traveling) I upgraded it when I purchased it.
Sounds like power supply thermal cutoff.
