Hi @DJ_Faisal, it really depends what input type(s) the mixer has. Many have RCA inputs so an RCA-RCA cable usually works. I normally just carry RCA-RCA cables and some XLR and TS adapters just in case.
You only really need balanced cables if you are doing long cable runs. If your cable is less than 2m (6’), unbalanced is fine. Either way, the Mixtour Pro doesn’t have balanced connections so you’re restricted to unbalanced anyway. Putting an XLR connector on the other end of an RCA cable doesn’t make it a balanced cable.
