Dialog cut off one Phantom?

[Mohmm]

Everything work perfectly now, after I connected both speakers to the same outlet! The Dialog is on a separate outlet, but on the same line! No cut off or lag anymore, both got same volume!!

Thanks for the help!

Just a side note: If you don't fancy PLC, Dialog and the Phantoms would communicate via ethernet if wired to LAN. That's how I got rid of PLC, which I don't trust very much.
