Please don’t think I’m trying to insult your intelligence, but more than once, in my excitement with a new purchase, I’ve managed to confuse my inputs with my outputs. Equipment probably shouldn’t even work this way, but it tries, and sounds awful until I realize my mistake. Unplug everything, take a rest/break and start over fresh or even with another set of eyes to monitor your efforts. Sh-t happens. Hope it works for you.
