Picking up on two previous posts...
Routers: I'm having some issues in one of 'my' church installs. They recently installed a digital recorder which is picking up all manner of chirps and whistles. There is a router and 'Ethernet via mains' gear about a metre away. Investigations continue...
CD and other digital players: I discovered many years ago that these do not make good bedfellows with radio-mic receivers...!

The Ethernet via the mains would be the first thing to check out, I think. And then I'd look at the integrity of the unit's screening and those of cable connections. A powerful router within a metre could easily cause interference problems.
And yes, anything digital does not make good bedfellows with analogue radio mic receivers.

Even LED lighting could be causing problems. I was telling our lad about short wave radio this morning and showing him on a Sony portable. We couldn't pick up anything until I switched off the LED lights that were near the aerial. They were supposed to be 12V DC but there was obviously noise from the switch mode power supply getting onto the cables.

Re: Buzz/Hum Hm?
Reviving an old thread here...been having the same issue as the OP and the Avantone Customer Service guys confirmed the Mixcube just doesn't play well with the Big Knob Passive and suggested getting a powered monitor controller.
Now, my 'temporary' solution has been to use a travel adapter that has a plastic ground pin (I am in the UK and most travel adapters come with a plastic ground pin).
Wall plug > Surge protected power strip > travel adapter > Avantone power supply
This has eliminated the problem completely, no buzz from the Mixcube, no buzz from my main monitors...but not the safest options as far as I understand.
Is the only possible 'definitive' solution to use an ART DTI or similar then??
