If the audio system does not have SPDIF connection there are two alternatives.
- If your source has Red/White audio out jacks connect it directly to the audio system.
- You can also purchase a Y cable adapter either ¼” to RCA or 3.5 mm to RCA. Check your owners manual for the correct size needed. Plug the single end into the headphone jack on the side of TV and match the Red/White cables up to the input of the audio system.
