How to connect soundbar to projector – Multiple Ways

You can pair the soundbar to your projector in a variety of ways, and most of them are done via some sort of cable. However, there is one method we’ve mentioned that involves wireless pairing done via Bluetooth connectivity.

Here, we’ve described various methods for connecting a soundbar to a projector.

Method 1: Using HDMI/HDMI-ARC

HDMI is not only one of the easiest ways to link your soundbar to a projector but also the best one. Especially when you compare it with the other wired connections, this approach simplifies your setup by providing seamless audio and visual integration. Newer devices have HDMI-ARC, which is an improved version of HDMI and provides even better high-quality audio and video.

Here’s how to connect your soundbars to your projectors using HDMI/ HDMI – ARC:

How to Connect Soundbar to Projector Using HDMI

  • The first step is to turn off your soundbar and projector.
  • Next, you need to plug one end of an HDMI cable into your projector’s HDMI/HDMI-ARC output port.
  • Then plug in the other end of the HDMI cable to your soundbar’s HDMI/HDMI-ARC input.
  • Then, turn on both devices.
  • If required, configure your projector’s audio output settings to use HDMI and your soundbar’s audio input settings to accept audio via HDMI.

One more thing, you need to already have a media player connected to the projector. After all, you need to play something on the projector in order to listen its audio in the projector. You can connect your Apple TV to the projector, streaming devices, computer, etc. Also, if you have a Netflix or subscription of any other streaming platform, you can watch it on a projector from your iPhone or other devices.

For people who value both audio and video quality, HDMI connections are ideal because they just require one cable.

Method 2: Using Optical/SPDIF

The square-shaped TOSLINK connector is commonly used for optical audio connections, but SPDIF provides a digital channel that can be connected using either a TOSLINK or RCA connector. Take a good look at the input and output of your soundbar and projector before making any connections to make sure they are a perfect fit.

In addition to the circular RCA connector, which uses the conventional coaxial cable method, SPDIF also provides the square TOSLINK connector for optical connections. Therefore, to enjoy flawless audio, make sure your connectors are in sync. If you have made sure they are in sync, follow the process below.

Here’s how to connect soundbar to the projector using an optical cable:

How to Connect Soundbar to Projector Using Optical

Step 1: Turn off power on soundbar & projector

Make sure the projector and soundbar are both powered off to avoid any potential electrical problems during setting up.

Step 2: Locate Optical/SPDIF input & output ports on the soundbar & projector respectively

First, locate the Optical/SPDIF input port on your soundbar. Usually, it has a label that says “Optical In” or “SPDIF In.” Then, locate the optical/SPDIF output port on your projector. It may have a label that says “Optical Out” or “SPDIF Out.”

Step 3: Use the cable to connect the soundbar & projector

One end of the optical/SPDIF cable should be inserted into the projector’s optical/SPDIF output port. Then, connect the cable’s other end to the soundbar’s optical/SPDIF input port. After that, plug in and power on both the soundbar and the projector.

Step 4: Choose Optical/SPDIF as the projector’s audio source

Navigate to the audio settings on the projector’s onboard menu or with the remote control. The audio output source should be set to “Optical” or “SPDIF” in the projector’s audio settings. By doing this, the audio is sent to the connected soundbar.

Step 5: Play content to test the connection

Now, play some content, such as a movie or video, on your projector. Make sure the audio is playing via your soundbar by adjusting the volume. To change the sound settings and volume, use the remote control for the soundbar. Also, you can customize the audio experience by looking through the soundbar’s settings. A variety of sound enhancements, including bass and treble, can be changed.

Thanks to your soundbar’s optical/SPDIF connection, you can now relax and enjoy the enhanced audio quality of your movies or presentations.

Method 3: Using Bluetooth

The HDMI and the Optical/SPDIF method mentioned above to connect your soundbar to the projector uses cables. With Bluetooth connectivity, you can pair your soundbar to a projector wirelessly. But this depends on whether the projector or both devices support Bluetooth connectivity.

You can place your soundbar anywhere in the room (depending on the room size) while still keeping your entertainment area neat and tidy. With this method, you have the freedom to enjoy great audio without having to deal with the fuss of cables. Continue reading if you want a neat and simple setup!

Where to place a soundbar with a projector? 

Imagine that you have your excellent projector setup and are wondering where to place your trusty soundbar for the best audio quality. Well, we have got you covered!

Below is the Projector Screen

A traditional option is to place your soundbar directly beneath the projector screen. The sound is kept in close proximity to the action, guaranteeing that it properly matches the visuals. It’s like having a little movie theater in your house!

Above the Projector

Consider putting your soundbar on a shelf or wall mount just above your projector if it is ceiling-mounted. You will feel as though you are in the middle of the action. 

In Front of the Projector

Placing the soundbar directly in front of the projector, on the TV stand, or in the entertainment center can also produce amazing results. This configuration ensures that the sound is directed directly at you, resulting in a direct and clear audio path. It’s like having a front-row seat to the sound show!

On a Stand or Cabinet

Putting the soundbar on a stand or cabinet is an efficient option if you have a special media cabinet or TV stand. To ensure that the sound may travel easily, just make sure it is centered and unobstructed by any obstructions.

On the Sides

You may position extra soundbars on the sides of your viewing area to create a surround sound setup. When playing challenging video games or watching exciting movies, this produces a multi-dimensional audio experience that puts you right in the thick of the action.

Beside the projector

Putting your soundbar on the backside with the projector isn’t the smartest move. There are much better spots to position it for top-notch audio. So, skip the back and explore the front and sides for a more engaging sound experience!

Remember, the most important thing is to make sure your soundbar enhances the images from your projector. Therefore, make sure it is centered, not blocked by anything, and that it offers you the finest audio experience possible wherever you choose to position it.

Is a soundbar good for a projector? 

Absolutely, a soundbar can be an excellent companion for a projector! Here’s why:

Enhanced Audio Quality

Easy Setup

Normally, it is easy to connect a soundbar to a projector. There is nothing complicated about connecting these two devices together. All you have to do is use a cable and plug one end of that cable to the soundbar and the other end to the projector. And that’s mostly it.


There are a number of audio modes, adjustment settings, and connectivity choices available with soundbars. Because of their adaptability, your audio experiences can be customized to a wide range of preferences and content genres.

Wireless Options

Many modern soundbars are compatible with wireless connections, such as Bluetooth or Wi-Fi, which makes it even simpler to connect and stream music from your devices.


Compared to purchasing a whole home theatre system, soundbars offer a cost-effective method to upgrade your audio setup.

The quality of the soundbar itself, the audio of your room, and your personal tastes all play a role in how successful a soundbar is. A soundbar is an excellent choice if you value great music to go with your projector’s beautiful graphics.
