- An optical audio connection is a digital feature that transmits digital audio signals from a source to a speaker.
- The source can be a television, computer, or any other gadget with audio content, for example, music.
- Digital optical connections use light beams to transmit digital signals in order to prevent signal interference.
- The relayed signal is then processed by the amplifier with aspects like music volume being controlled by the volume buttons/knob.
- Inputs like aux are largely analog which causes breaks and loss of signal.
- Where an optical input is available, it is the best connection to use for playing music on your soundbar as an alternative to HDMI.
