Severely clipping Mixup - did i bust it?

I’ve been using a Mixup as my in-rack mixer for ages now, but today when I turned on my system I discovered that normal sound sources get VERY clippy with the knobs past 12 o’clock - and the fourth knobless input severely clips no matter how quiet the source sound is. Could I have busted it somehow? It’s pretty much unusable now, I’ll definitely need to replace it.

The only thing I can think of is that earlier this week, I had my system running for a full day with the Mixup in use on all channels… could it have damaged the electronics somehow?

Never heard of leaving a system powered on damaging the electronics.
