Mike - in that case, it could be a hardware fault. If the same thing happens even with the turntables disconnected, then it's definitely a fault.

Please contact a Pioneer DJ authorized service centre in your region to have your hardware inspected and/or repaired.

Additional info - the hum can be heard in headphones as well

Did you ground between the turntables and the mixer?

Yes I did

That actually may be contributing to the problem - please try disconnecting the grounding wires as the PLX-1000's are internally grounded.

Good to know. Unfortunately that doesn’t seem to be the problem.
Also only getting loud hum in right channel. Left channel is quiet.
