First, I want to say that I can not quite understand it, that some reviews are so negative here. I had the problem that I only have one optical input on my new home cinema system. However, digital sound I wanted both my Sky receiver and my PS3. Thus, there was only the possibility (even if it is, admittedly, not necessarily the most comfortable) to work with an optical switch. In expert market around the corner so I bought a cheap ado switch of Hama with two parallel inputs. Problem here: As soon as both input devices are running simultaneously, there is a feedback loop that may damage the equipment. Furthermore, I have to connect the Switch directly from Hama destroyed while trying times 2 optical cable, since the terminals do not fit - but I thought, "That must go yet!". Result - refer to the earlier text and to gabs free frustration. The offered here Switch provides on the one hand the possibility of switching to the respective output device, is on the other hand for this price segment tremendously well made and works for me exactly as you want it! From me there is a strong buy recommendation for all who have too few optical inputs for too many digital output devices!
