The KanexPro digital to analog audio adapter converts digital S/PDIF or optical (TOSLINK) audio input source to RCA output. Ideal for connecting to equipment such as an A/V receiver or recording deck via standard RCA connectors. Now you can link legacy sound system with digital sources such as Blu-ray player, DVD and CD players that don’t have RCA-style analog outputs. The converter is compact in size and requires minimal setup.
