Yesterday I added a HD Cable box to an existing system. Also reprogrammed RTI T1 remote. I did this job 2 years ago. Budget job, but nice. Monitor Audio Radius Inwall’s (Front and rear), RBH inwall sub-woofer, Pioneer Receiver VSX-1016, LG DVD recorder, Infocus Projector, Da-Lite Electric Screen. Lutron Spacer Dimmer. And yes, that is a Xantech IR receiver under the center speaker. (Customer should have put RP-1 instead) Again the budget job thing!
