Hello everyone, I must admit that i have no idea how C-bus works and i have never seen or heard of this system, until i got a surround reciever from English Cambridge Audio that supports it. Now ... My question is as following: Is there any way that i can use a CD-player, to trigger out 5/12volt, into a C-bus controller of some sort, that will then sent a signal to my Cambridge Audio 650r Reciever, that then detects it, and starts up by itself and choose which input to use? [URL]http://media.tas.zeitpress.com/articles/images/Cambridge_rearpanel_detail1.jpg[/URL] This is a picture displaying the Bus-ready input, which Cambridge calls Incognito. The solution i was seems pretty simple. I don't want any fancy built-in things in my wall(Atleast not for now :o) ), i just want this system to be turned on and set to the right input, by a 5/12volt trigger signal. You guys got any advice/tips for me? Best regards Jesper :)
