QSC K12 self powered speaker shuts down at high levels

[cablercdd1]

I'm not very good with the newer Class D type amps. When I turn the input up to about half way on this self powered QSC K12 speaker it shuts down the audio but stays powered up. Turn the volume down for a few seconds and it starts to work again. I just thought I'd put it out there to see if anyone has had experience with this issue.
