I purchased a Radio Shack Toslink to PMC Coverter which I will be hooking up between my Dish network Satelitte dish receiver and a Pioneer receiver. The dish has a opitcal output and the Pioneer has a coax input. I want to receive dolby digital from the satelitte but not sure this converter will allow it. I'm confused about this PMC(Pulse Code Modulation). Any help would be appreciated) Thanks.
