Greetings. I am a musician and have used the Bose L1 compact for gigs since around 2010. Lately I have getting popping noises from the loudspeaker array as soon as I plug it in, whether the volume is turned on or not. The sound level fluctuates of it's own free will and is sometimes audible to the audience.
I'm not sure if this is an internal malfunction or something that can be fixed by cleaning it with rubbing alcohol or whatnot. Has anyone else had this problem. and what was your solution? Thanks.
