I want to connect a second device to the 5.1 analog (6 RCA cables) "external inputs" on the rear panel of my old Denon AVR 3805. I have my blueray player (which I also use for CDs) connected in this manner and the sound is awesome. I'd like to connect a second device in this manner but there is only one set of 5.1 analog inputs. There are all sorts of switches made to connect multiple devices to one regular composite audio/video input (red, white and yellow) but I've found nothing similar for the 5.1 analog inputs. Does anyone have any suggestions as to how I can go about connecting a second device to these inputs? Thank You.
