Yep, familiar with those principles. My studio is at a pro level and devoid of any sort of hum or noise. It's only when I connect the digibox into the gubbins that I get a hum. The hum is the worst I've ever heard regardless of gain/level settings on the mixers. Hence the reasons I've asked you guys. Thanks for the responses, I'm awaiting the ground loop isolator.
Whilst I've got your attention, I wonder if you could comment on a scrolling ghost-like horizontal line on my tv's. It's the same on all. It's more apparent at switch-on in the mornings. The present receivers from the quad lnb are panasonic 31 &50 and a thomsonD/3. I've substituted grundig and pace receivers. It seems to disappear as the day goes on.
