Question

my classic studio live 24.4.2 started by showing an overloaded signal on all channels. after being turned off for awile it worked fine for a couple gigs but on a third gig it jus died.turns on but it will not pass any sound on any channels.

Answer 1

It looks that there is nothing you can do any more (factory reset or the like). Your mixer obviously needs a repair. Go to your PreSonus account and open a ticket.
