This is a used digital to analog audio converter, designed to bridge the gap between your modern digital audio sources and traditional analog sound systems. If you have a TV, Blu-ray player, or gaming console that outputs only digital audio (like Optical Toslink or Coaxial SPDIF) and you want to connect it to an older stereo receiver, amplifier, or headphones with RCA L/R or 3.5mm inputs, this converter is the solution.
