Although warned by the many negative reviews, I have nevertheless decided to test the adapter, since you can not go far wrong with the price. I wanted to connect my Xbox 360, PS3 and Apple TV with my receiver, which unfortunately has only two optical connectors and therefore came up with the idea to give this optical distributor an opportunity. Unfortunately it does not work, although there is light at the end and I never two devices at the same time, however, the signal seems to be too weak. Without adapter, with a direct cable connection everything does not work perfectly, with clutch unfortunately. I have different Toslink cable lengths and tried, unfortunately without success. I guess if it works for someone or not depends heavily on the receiver used and the cables used and the cable length. I have now ordered my electrical distribution, which amplifies the signals and hope that this my problems eliminated.
