Hi Dave and Keith,
I have a tested and completely balanced setup, also the amps connected are full balanced. The hum was heard tru HP amp AND main and studiomonitoring. I understand about getting a system well earthed etc...
and what cables to freefloat the ground, and wichones not too, in case unbalanced components come into play.
This was a mobile setup for a few days of rehearsalrecordings only, although with the experiences gained recent, this seems like a perfect preproduction setup too. Supertool as warmup for band and assistant :wink: a few days before starting in the studios.
To come back on the ground loop thing, even with all of the cables removed from the linked consoles (exept the link and 1 set of monitors of course) we got hum on the balanced mainsspeakers, it only disappeared when we removed the earth from one of both the PSU PCB, that is: not where the 110 comes in but in the middle of the PCB where the 5, 12, 18 and 48v are made.
Anyway, I'm a happy Tony once again, thanks for helping out.
I will learn about drawing stuff to post here too, making a lot of my endeavours more easy to explain :green:

PS1 Michael, Hellgium is this part of Belgium with loads of:
{cynic :evil: mode on}
corrupt politicians,
strange working justice departments,
incompetent staff at crucial places at work (go to this person to find out that, and overthere they know jack sh*t about their own department,
overtaxing of the population & especially independant employed people (always have been easy bate) by the government,
too much meat industry,
fast growing racist inspired population (and stupid media in their best effort making this even look bigger) and ....
stupid weather, when it's cold it feels even colder, when it's hot, it feels hotter (too much humidity in the air - today we had 34°C, the day before yesterday hardly 17°C, this happens all the time and I hate it),
ozon pollution, industrial pollution, farmers have been thrown too much dump on their fields for years, soil is acid as is all underground and surfacewater, what they didn't kill, industry soon will finish, aaaarghh.
The day before yesterday we saw a report on the TV-news about tests done on the blood from the umbellical chord of youngborn kids showing Belgian kids get born with extreme high levels of heavy metal (cadmium, ...) dioxines and other crap!
well don't get me started huh :twisted: :evil: :evil:
I would love to live outside this country for 1000's of reason's...
(Dave, if you need an assitant in North Italy, we need to talk :green: )
Maybe one day, when I feel p**sed enough I'll start a thread in the Brewery about this. {cynic :twisted: mode off}
PS 2 I want a better analog setup in my first studio as with this experiment it became once again very clear that analog rules bigstyle over a lot (if not ALL) of digital mixers...
Anyone feel like pointing me to a good midclass console for tracking and everynow and then mixing? A*M*E*C 2500 or something like it?
In the 2nd room the long talked about SSL will be installed, pictures in few weeks, to drool on :green:
PS 3 :roll: was I hyperventilating a while ago???
