I haven't really begun to dig into this but I'm posting in the hope that someone else has had a similar experience and might say "oh yeah, it's this…"
I frequently use my S1 as a personal monitor at low volume acoustic solo gigs. I am plugged into it from the output of a ToneMatch mixer. Not red-lining the S1 channel at all.
Finished a set, came back from my break last and the power light is off. Thought maybe someone bumped the switch but it was in the on position. The unit was a little bit warm so it hadn't been off that long. Turned it on and off, nothing. Completely dead. I was inside with air-conditioning so I doubt it's thermal. Tried with a different power cord and again this morning at home. Nothing. No battery installed. I own one but have never used it. I've only had this unit for 6 months and never abused it.
I know Bose doesn't typically like us opening up their stuff but could there be a fuse inside?
Thanks. - Rob
