Reply to audio 8 dj and krks for producing

Hey world,

I'd like to know if its good to use an audio 8 dj for Music production? I only need it to connect my krks and maybe a mic for vocals but thats it.
My only concerne is if i will have any problems with the rca connection cause they audio 8 only got rca and i often read that rca is not good for music production.

Thanks for all replys.
