The C2G TOSLINK Digital Audio Selector Switch converts any 2-channel TOSLINK optical input into three inputs, enabling you to connect, for example, a DVD player, a Blu-ray player, and a game console into one speaker system receiver. The Switch features one 2-channel TOSLINK output for connection into a speaker system or other system, and three 2-channel TOSLINK inputs for connecting DVD players and other devices.
The Switch is not compatible with ADAT TOSLINK inputs because they are 8-channel inputs. ADAT and 2-channel TOSLINK connectors look exactly the same, but ADAT TOSLINKs say "ADAT" next to them, so you'll be able to tell the difference.
