OREI Dolby Digital To Analog Audio Converter Decoder -SPDIF/Coaxial Input To RCA Output (DA34)

I use this to connect my Samsung 65" 8000 Series SUHD 4K TV's ONE CONNECT BOX to a PyleHome PSBV200BT 300W Bluetooth Soundbar. The soundbar only accepts RCA connector input. One piece of information not included in the description, VERY IMPORTANT, is that this OREI DA34 DID COME WITH A DIGITAL OPTICAL CABLE. I did not measure it, but it is about 3-4ft in length. Going by the write-up I was concerned that I would need to purchase one. Was glad to see it was included.
