I have a home theater system with just one optical input. But the 3 devices I wanted to connect it.
This optocoupler is now possible. My PS3, PS4, and the TV itself is on top of this unit. A short cable is connected to the home theater system. The input channels (up to 4) can be switched with the included remote control, or on the device by pressing a button itself. There are 2 outputs it (A & B).
Fast shipping and great flawless functionality without sound delay characteristics of this instrument.
