Did you ever jostle a connection from a mini jack to a PA? Sounds like thunder. Bad form on a gig.

Beating a dead horse even further, it’s not even the right signal to send to a PA or powered speaker. The mini jack is after a volume control (a rheostat that can introduce noise of its own) and it makes the voltage vary. At full volume, it’s more than a line-out signal, so you have to back it off but there’s no way to know without measuring the signal if it’s about right.
