How to Connect a Fiber Optic Audio Cable to a TV


Certain modern televisions manufactured today may feature several different audio input and output connections, designed to accommodate a wide range of compatible external A/V components. Digital optical connections, also known as TOSLINK connections, have the ability to transmit digital audio signals through a small fiber optic cable. Compatible televisions may feature a TOSLINK output connection, which may offer improved sound quality over standard RCA analog connections. Connecting a fiber optic cable to your compatible television is an easy task that only takes a few minutes to complete.

Things You'll Need

  • Digital optical cable
  • Compatible Television
  • Documentation supplied with your television
  • Turn off the television and the external audio receiver.

  • Examine the rear portion of the television and locate the "TOSLINK OUT" or "DIGITAL OPTICAL OUT" connection.

  • Remove the protective caps from each end of the digital optical cable, if applicable.

  • Insert one end of the digital optical cable into the appropriate "TOSLINK OUT" or "DIGITAL OPTICAL OUT" port, located at the rear of the television. Both ends of the digital optical cable feature a distinct shape that corresponds with the optical port on the television.

  • Connect the other end of the digital optical cable to the "TOSLINK IN" or "DIGITAL OPTICAL IN" port, located at the rear of the audio receiver.

  • Turn on the television and enter the setup menu. Change the audio output settings from "Internal Speakers" to "S/PDIF" or "DIGITAL OPTICAL OUT." Refer to the documentation supplied with your television for specific instructions on how to change the sound output settings.

  • Turn on the external audio receiver and select the appropriate audio input source. Adjust the volume and sound field settings as necessary.
