Hi, i have a beosound9000 in the living room and have just had opus 500 multiroom fitted in all rooms ,i have taken an audio output from my beo into the opus, i want to be able to switch disks etc, volume track etc on my beosound 9000 upstairs but the ir protocol is different on the B&O stuff, am i right in thinking if i purchase one of the harmony universal remotes i would be able to control the beo? or is there something else out there?
