Need help with setup

I have one Xone K2 and one Xone 42, I am really confused about the setup. I am also getting another Xone K2 so I can use them as a soundcard. Can someone tell me what I need to complete this setup, I am thinking 6 RCA’s, 4 in the back of my Xone 42 and 1 each in the back of my K2. I still don’t get it because I don’t know where the other end of the RCA’s would go.

Youve not explained what you are actually trying to achieve.

Read the manuals and learn to use the gear you have bought. The manuals have connection diagrams.

The K2’s only have one output channel, so even with 2 linked up you would still only have 2 channels of audio to your mixer. I would suggest getting a 4 channel soundcard and just use the K2’s as controllers.
