When you want to improve your home audio experience, a soundbar is a simple yet effective solution, especially when connecting it to your TV. There are two common ways to connect a soundbar to a TV: using an HDMI ARC connection or an optical audio cable.


HDMI ARC (Audio Return Channel) simplifies the audio setup by combining audio and video transmission into a single cable. It allows your TV to send audio directly to the soundbar without the need for additional cables or connections. To connect using HDMI ARC, follow these steps:

  1. Identify the HDMI ARC port on both your TV and soundbar. It should be labeled as “ARC” or “HDMI ARC”.
  2. Plug one end of an HDMI cable into the HDMI ARC port on your TV, and the other end into the HDMI ARC port on your soundbar.
  3. Turn on both devices and ensure that the soundbar input/source is set to HDMI ARC.
  4. Your TV should automatically detect the soundbar, and your audio should now be coming from the soundbar instead of the TV speakers.

The HDMI ARC connection allows for improved audio quality, supports various audio formats, and enables easy control from your TV remote.

Optical Audio Connection

An alternative method to connect your soundbar to a TV is by using an optical audio cable. It provides a high-quality digital audio connection between your TV and soundbar. Although it doesn’t support advanced audio formats like HDMI ARC, it still delivers excellent audio quality.

To establish an optical audio connection:

  1. Locate the optical OUT port on your TV, and the Optical IN port on your soundbar. These ports might also be labeled as Digital Audio Optical Output.
  2. Connect one end of the optical cable to the optical OUT port on your TV, and the other end to the optical IN port on your soundbar.
  3. Turn on both devices and switch the soundbar input/source to optical or digital audio input.

The optical audio connection is an easy-to-setup and a reliable way to enhance the audio experience when watching TV or streaming content.

Remember that you should choose between HDMI ARC or Optical Audio Connection based on the available ports on both your TV and soundbar, as well as the desired audio format support.
