ACtually the Pro comes with 2 ir's, so you can control two devices. Depending on where you place them you could actually control morethan one device with one ir. In order to use all 4 input's on the pro you would need the hd adapter. The adapter comes with 4 ir's. Regardless if you have a two or four headed ir cable, they are all on the same cable and have just the one plug in (but still controls the multiple devices)
