If your equipment have both outs/ins XLR and RCA more-likely it's not balanced. The true-balanced equipment has only balanced outs and that where it makse the point and sence. There has to be an output transformer present that separates positive and negative signals onto different signal wires. If you open up the cover you will realize whether the equipment balanced or not.
I always prefere the equipment that has either one of... instead of having both.
