kemper has audible pulsing with display flicker

hello:

i have a kemper and today the amp began having issues. the display is flickering and there is an audible pulsing. interestingly, the
pulsing matches the tempo set on the box.

can anyone provide any advice/troubleshooting for the amp, please?

thanks in advance,
j

bizarre- after having reset the output settings and verified cabling to the outputs the issue has resolved.

great ending.

thanks,
j
