I bought this distributor saying that shutting my devices, only the source in motion would transmit information via optical my home theater. Big mistake on my part. FYI, I have a FreeTV a WD TV Live Peekton and DVD player. Only the DVD does not send optical signal when off. The standby FreeTV always produces an audio signal (red light). Ditto for the WD TV Live. And in terms of the DVD, the quality is not as good through the dispatcher, I think as the other input was not connected, there had to be light pollution.
So check before your sources produce no residue signal even in standby.
So I give the average product that apparently fulfilled its function, but does not meet the need of everyone. So I spend the switch, more binding than just turn all devices with remote control logic but at least it works.
