Sorry, total beginner here. Purchased a house with projector and screen. The Denon AVR-4500H came with the house and sits in a network room 2 rooms removed from the screen. I added my Sony blue ray player to the AV rack but have to go the the network room to control the blue ray player with the blue ray player remote since I haven't figured out how to control the blue ray player yet with the Denon RC-1240 remote I just purchased. I am trying to locate the manual for both the receiver and the remote but haven't had much luck. Any help would be most appreciated.
