The KanexPro Digital to Analog Audio adapter converts your digital S/PDIF or Optical (TOSLINK) audio input source to RCA output. Ideal for connecting equipment such as an Audio Video receiver or a recording deck via the standard RCA connectors. Now you can link your legacy sound system with digital sources such as a Blue-ray player, DVD and CD players that lacks the RCA-style analog outputs. The converter is compact in size and requires minimal setup.
