Dealer time. Maybe the UPS guy dropped it, sat on it and used the box as a chair while eating lunch.
Warranty. It happens with every piece of gear on occassions.
Also check , check, cross check, and do a backward check. And do the process of elimination. Try all outputs, (monitor section, headphones)
It might not even be the X desk. Cables, try a different outlet, turn everything off that you can and test. Test, test, test. And you will find the culprit.
Sometimes I get hums in my 1176s and then they go away. I got hums on my vintechs which never go away

. I just consider it part of the sound now.
Could be the electrical current, poor grounding. Did your shipping box looked crushed or damaged in anyway?
I had one guy I sold a brand new compressor to...he plugged it up and smoke came out of it. What was the problem? Wrong voltage. It was set on 110v. He lived in Europe. Ouch. Brand new $3500 limiter torched..
Complex...it can be. Good luck.
