A digital optical audio connection is used to send an audio signal from a television to a surround sound receiver. This is a single cable that provides all of the audio information required by the receiver. However, if your receiver (or whatever device you are using) does not have an optical digital audio cable input, you must convert the optical audio cable to an RCA connection.
Things You'll Need
- Optical digital audio cable
- Optical to RCA adapter
Insert the optical digital audio cable into the "Optical Digital Out" port on the television or other device you are sending the audio signal to.
Connect the opposite end of the cable into the optical end of the optical to RCA adapter. This converts the optical digital cable into an RCA connection.
Plug the red and white RCA cables of the RCA connection into the "Audio In" port on the device you are sending the audio signal to.
Power on the television and the and the device you are sending the audio signal to. The audio signal now plays over the connected device through the optical audio to RCA connection.
