About

My surround sound system only has one Coax S/PDIF input, but i currently has two and soon three sound sources i want to connect digitaly to the receiver, one trough Coax and the other two trough optical toslink. To acomplish that i build a S/PDIF switch witch switches between two coax and two toslink inputs to one coax output, using the surround system's remote control.
