Static from mixer

So this is happening, I don’t have the assigned player to that channel playing anything but my mixer is recieving something? It’s causing static sound coming from my speakers. The cables I’m using are the ones that come with the sc6000’s. And it doesn’t matter what song I have loaded it’s still causing this problem. Any ideas as to what it might be?

Powered speakers?

Static audible in headphones too and recordings or only audible over the main speakers?

Anything else plugged in , especially laptops or usb ?

Yea standard powered speakers, no static through my headphones, I haven’t yet recorded anything so I’m sure about that and nothing else is plugged in just my 2 players, power supply, 2 xlr cables and the link cables for the players
