Hello, ive been working in a studio here in Lisbon, and there is something weird with the 220v current. They have been experiencing come and go noises, and i could detect that Air conditioning and the coffee machine in the lobby make audio clicks in the control room.. Basically is whenever its thermostate relay works whether to open or close circuit.
They also have problems with tube outboards, like their LA2a, Retro compressor, UA 2-1176 and the brand new ADL 670...
Although im using only Wunder U47, into neve 1073 into ADL 670 atm for tracking vocals without any noise at all ive been told that tube gear should been avoided until they get someone to see what happens...
It seems the earth "Stick" is ok and the studio have its own, the voltage is 220V, one fase only i believe, and they said that measuring earth to neutral they had 0,4V. this shouldnt be a problem right?
They have alot of stuff like ups and i believe one "AC-DC-AC converter?" never heard of this one...
Can anyone explain me how to see if the power there is ok? what should i read besides voltages and frequency? is there things to avoid like UPS placement, shoud this be out of the control room?
Fixing the power as they say it need to be fixed? will this AC and coffee machine stop doing clicks? could this be "smoothed"?
ANy help is highly appreciated!
Cheers
