How To Set Up A Soundbar To TV

A soundbar can be connected to your TV in a few different ways. The most common soundbars are setup using an HDMI cable to your TV in the “ARC” port. This common setup allows any sound you are hearing from your TV to be output and heard through the soundbar.

Once setup, adjusting the treble, midrange, and bass can help you hear the sounds meant for the movie theater and live sports. These settings can be adjusted for anyone hard of hearing and needs the audio louder and cleaner for speech to be heard. See here if TV has no sound.

Audio Cables Used To Connect A Soundbar

You can use an HDMI cable, Digital Optical cable, or RCA tv cables. The easiest way is an HDMI cable.
1. HDMI cable (Carries the most uncompressed digital data for higher surround sound systems from 5.1 to Dolby Atmos)
2. Digital Optical/Coaxial cable (Transfers digital audio up to 5.1 surround sound)
3. RCA cables (Carries only analogue audio NOT digital audio – These cables cannot deliver a 100% digital surround sound)

Should I Use An HDMI Cable?

Using an HDMI cable is the easiest way to connect your TV to a soundbar. An quality HDMI cable carries large amounts of digital audio and works with the highest surround sound systems. You can use just one HDMI cable from the soundbar to the TV to connect it and be done.

How To Connect A Soundbar To A TV With An HDMI Cable?

To connect your soundbar to your television, be sure to check the TV’s HDMI ports for a port that is labeled “ARC”. Connect one end of the HDMI cable to the TV’s HDMI-ARC port and the other end of the HDMI cable to the soundbar into the HDMI-ARC port. Once connected through ARC, turn on the TV and soundbar to test the setup. Check here if the TV does not recognize the HDMI cable.

Make sure you have a long enough HDMI cable. If the HDMI cable is going “through the wall”, you may need a few feet longer than initially thought. There may be a cap covering the end of the HDMI cable so be sure to remove it before inserting it into the HDMI port.

When connected using ARC, to connect other components to play video games (Xbox) or watch movies (blu-ray), plug the HDMI cable from the component you are connecting into the soundbar HDMI IN port.

When the soundbar is setup and working properly, go into the TV menu and scroll to “audio”. In this menu, you can turn OFF the TV speakers so they do not turn on when using the volume button on the remote control of your soundbar.

What Does ARC Mean On TV Port?

“ARC” = Audio Return Channel. ARC means the audio is able to travel in both directions. Most new HDTV’s (and soundbars) have an HDMI marked “ARC”. This means one HDMI cable from your TV to the soundbar will get you setup. Once the cable is connected through ARC, you can connect all your components (Xbox, Blu Ray) directly to the soundbar and not to the TV.

Should I Use RCA Cables To Connect Soundbar?

Before using RCA cables to connect your TV to the soundbar, know that these cables cannot carry true digital audio. Use an HDMI or a Digital Optical Cable instead. If you have the choice, use an HDMI cable in place of RCA cables. RCA cables will not deliver true digital sound.

How To Connect TV To Soundbar With RCA Cables?

If your soundbar only has RCA connections, here is how to connect them. RCA cables use only the RED wire and the WHITE wire for audio. When connecting audio with RCA cables, ignore the BLACK cable. The BLACK cable is used for VIDEO inputs only.

Plug the RED RCA cable into the RED RCA port on your TV, and the WHITE RCA cable to the WHITE RCA port on your TV. Take the other ends of the RCA cables and plug the RED cable into the RED port on your soundbar and the WHITE cable into the WHITE port on your soundbar. Once the connection is complete, turn on the system and test for proper connection.
