I was looking at acquiring the newer model Kenwood Home Theater in a Box HTB-544. However, I understand that this system now comes with the Kenwood VR-509 receiver. Evidently, this system has a remote and works on RF as well as IR. Kenwood's literature seems to be extolling the virtues of RF in such a way that it leads me to believe that maybe the VR-509 itself only works via RF signals and not IR? My question is this - can I control the VR-509 solely by way of IR? Would I be able to use my Pronto to control the VR-509? If not I would just go back down to the HTB-504 with a VR-507, but obviously newer would be nicer. Any help you folks could provide would be greatly appreciated.
