This is an amp typically used for commercial installations so it only has wire tap type inputs and outputs. The inputs are balanced however so you must wire up XLR connections yourself. These are mostly used to power subwoofers, and multiple speaker systems in resturants. When installing these amps please make sure you are using a surge protector on the amplifier.
