Everything is on the same surge protector except for the TV which doesn’t have a long enough cable. I’ll try extending it and plugging it into the same connection. I don’t remember 100% but I think the problem was still happening even when the TV power was not connected.

to repair this costs 5€ (7$)… sorry could not withstand

You’re right. My plan is to repair the Xone:22 and sell/give it away. I’ve had it since 2011.

the connection to the amp is not the problem I guess…it will not change

You were also right. The XLR cables didn’t do anything, but they are nicer than the RCA ones. It turns out that the 1/8″ ->RCA cable connected from my TV to the receiver/amp was the culprit of the humming. When I disconnected it, the noise went away. No combination of connections and eliminating ground loops would make it go away unless I unplugged that cable. I probably need a better way of getting audio from the TV.

So for now I have the inconvenience of having to alternate between having the TV output plugged in and the Xone:23 plugged in, but at least I can happily mix.

Thanks for the help folks.
