I use the Recoton optical switcher - gives me 3 optical inputs to plug into one 1050 input - manual switching but it works for me - I have my CD changers into op1 & on switcher in op2 along with DVD . I have a 3rd older changer that has only analog output - so I can remotely chose CD - op1 or op2 (manually preselected on switcher) or analog - depending where the cd is located - I use these with the Nirvis Slink-e device that will allow me to select songs(with lyrics)or albums (with cover art and contents)from my computer (projected on my TV monitor). The Slink-e downloads info from internet automatically - I have to change input however using remote when device moves from one changer to anonother - Nirvis has another device ($$$) that can change optical inputs automatically, however.
