| br>soooo..... went on vacation, turned off all the power supplies in my music room, etc. just sat down to work on some stuff, turned on my mixer, and OOF.
huge feedback surging started pumping out of my speakers, even with the Main outs turned down. turned everything off. unplugged all the inputs and the speaker outs and the USB input, turned it back on, flickery input peakings galore. tried a different power supply cord, same thing. noticed a burny circuit smell so flipped it off and sent an email to PreSonus support.
sounds like it is horribly, irrevocably fried to me. but i'm a git about mixers.
any suggestionnnnnnnns? br> br>
