UR44 hum noise

Steinberg Hardware UR Series
1

I have a new UR44 interface. Very simple setup. UR44 is switched on a multiple power strip and is connected to the PC via USB. I connected the my passive bass, that I play here to Input 1 (Hi-Z) by cable. I’ve tried a lot of cables, I don’t think that’s the source of the humming noise.

Can someone please give me a tip what to look for.

Is the power supply of the PC on the same outlet than the UR44?
If so try to turn the power plug of the UR44 by 180°…
What kind of PC is it?

Hi st10ss,
you pointed me to the right direction. I pluged the UR44 into an other power (wall)plug and the hum was gone. Thank you so much!!!
