I have chronically short optical audio inputs to my AV receiver, and have therefore bought this turnout. In order to connect two devices to one input. This works quite well, one is compelled while always shuttered only an inserted device, because otherwise both signals would like the input simultaneously. If you send both signals simultaneously, either comes garkein tone or just the sound of the "more dominant" device. The tone of the second device is thereby virtually suppressed. But this is not all bad, because you want to hear the sound from only one sound source at a time anyway. The switch does just that which is why I bought it. I do not have forever changing, if I want to change the device to my AV Receiver.
