What is optical input and how does it work on soundbars?

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