I currently have a AVR-2500 and am planning on purchasing a Denon 3805 for the basement HT when I finish the basement. I intend to use the AVR-2500 for my second zone...which will be stereo speakers in my great room. My wife wants the reciever out of the room and only wants the speakers. So both recievers will be in the same rack downstairs. I want to be able to control volume and CD changer from upstairs and plan to get a IR extender. The problem will be when I want to increase volume or change inputs on the 3805 or vice versus I'm assuming the codes will be the same and will change both. Is this correct? Any way to live with it?
