HI all I'm in desparate need of some help/advice and someone recommended that I post in here.
I have setup all of my DJ equipment in my Japanese apartment but I am getting a lot of hum/noise from the power lines through the system which increases if I turn lights or other significant bits of electrical equipment on in the apartment.
I have a Formular Sound FF-4000 mixer (bought from the UK but configured for Japanese voltage).
2x Focal shape active monitor speakers (again from the UK but I've changed the voltage switch to 100-120v) (connected using the balanced outputs and XLR cables)
2x Technics SL1200 turntables bought in Japan.
All of the items are going through a grounded power block which is connected to a ground socket (I can only assume this is working I don't know for sure). I have tried connecting the ground to a pipe in the kitchen too (via another long ground cable) but this didn't do anything but my method here was likely flawed as I just stuck the cable in place as a test.
I tried disconnecting everything except the mixer and listened through the headphones and I still get the feedback (which increases as I turn things on in the apartment) so I think there is a fundemental issue I'm desparate to solve.
Any thoughts on what I can do/purchase/further checks to solve this issue as it's pretty bad!
UPDATE:
Also I've just tried plugging it all in to a different socket and all of the hum has gone so I'm guessing it means something on the other sockets is causing the issue (although I've turned everything off and it's still there).
