How To Connect Soundbar To Projector?

How To Connect Soundbar To Projector? You can use an optical audio cable to connect your soundbar to your projector. Optical connections use light to transmit digital audio signals, which results in a clear and high-quality sound experience.

First, check the input ports on your projector and soundbar. Ensure that they are compatible with the type of cable you want to use.

Features Of Connect Soundbar To Projector

  • The best soundbar for your projector depends on the kind of content you plan to watch and play, room acoustics, and budget. Ideally, you should consider a model that has dialogue enhancement capability because this makes voices clearer and easier to understand when watching movies and TV shows. You should also look for a model that supports high-quality codecs like Dolby Digital and DTS.
  • While many newer soundbars and projectors feature HDMI ARC ports for easy connection, you can still use other analog connections if your devices don’t have this port. For example, you can connect a stereo audio cable with RCA connectors to the projector’s left and right channel outputs and a stereo 3.5mm input on your soundbar.
  • Another option is a digital connection via SPDIF or TOSLINK jacks. This type of cable offers excellent quality and can transmit surround sound if your projector and soundbar support this technology.
  • Finally, Bluetooth is a convenient wireless connection method for projector-soundbar pairing. However, you should note that this option can be susceptible to interference from other electronic devices and may deliver lower-quality audio compared to analog connections. Moreover, you need to enable the Bluetooth function on both devices and pair them. Refer to your device’s user manual for detailed instructions on activating the Bluetooth feature. Once this is done, you can stream audio to your soundbar from a source like a laptop or a smartphone.


Whether you’re a movie enthusiast or a gaming aficionado, the right soundbar and projector can elevate your home entertainment system to new heights. Using an HDMI cable, you can connect your devices and experience larger-than-life visuals and rich cinematic audio.

If your projector and soundbar have HDMI ARC ports, you can use an HDMI cable to transmit audio signals between them. This method is convenient and provides the highest quality audio available. However, you should be aware that you won’t be able to access Dolby Atmos content through this connection.

If your projector and soundbar do not have HDMI ARC ports, you can still establish a connection between them with RCA cables. To do this, turn off both devices and find the RCA output and input ports on their rear or sides. Connect one end of the RCA cable to the corresponding ports on the projector and the other end to the input port on the soundbar. After connecting the devices, switch them on and test the sound. If necessary, adjust the settings on your projector and soundbar to ensure that they are properly connected.


Inspect the back of your projector and soundbar for RCA ports. You may have to remove the cover to access the port. Make sure to turn off your devices to prevent any electrical issues during the connection process. Next, get a high-quality optical cable. One end should have a square TOSLINK or SPDIF connector and the other end should have stereo RCA connections. Insert the cable into an RCA input port on your projector and an RCA output port on your soundbar.

If you are using a stereo RCA connection, you will need a 3.5mm audio splitter to connect both left and right channels to your soundbar. This method is best for delivering rich and immersive sound.

Once the connection is complete, test it by playing a video or music track. If the audio is relayed through your soundbar, you have successfully connected your projector to a soundbar and unlocked the potential for an exceptional home entertainment experience. If the connection isn’t working correctly, check the wiring and try again. If the issue persists, consider contacting customer support to resolve the problem.


AUX cables are not as reliable as HDMI connections and can cause a delay in audio-video synchronization. However, they can work well if your projector and soundbar have a compatible auxiliary port. In addition, AUX cables can be much cheaper than HDMI cable alternatives.


Connecting a soundbar to a projector via an auxiliary port is possible, but requires the right equipment and proper setup. Start by making sure both devices are turned off to avoid any electrical issues during the connection process. Then, locate the RCA output and input ports on both devices. Connect one end of an RCA cable to the projector output, and the other to the soundbar input port.

Lastly, plug the other end of the cable into an external source like a Blu-ray player or streaming device. Power on both devices and test the connection by playing some content. Once the connection is verified, adjust the audio settings to fine-tune your listening experience. Whether you’re embarking on a movie marathon or unwinding with your favorite tunes, a properly connected projector and soundbar can enhance every moment with captivating sights and enveloping sounds.

Digital Optical

If your projector and soundbar feature optical audio ports you can use an optical cable to connect them. This is the best option for high-quality digital audio, but it’s important to make sure that your source device also supports this type of connection. Otherwise, you may experience a mingling of audio frequencies and distorted sound output.

Start by ensuring that both devices have a SPDIF (toslink) port. These are typically square-shaped with a cover. Remove the cover and insert one end of an optical cable into the projector’s Optical Out port and the other into the soundbar’s SPDIF In port.

If the setup is successful, you should be able to hear audio from your projector through the soundbar. Test it by playing content to confirm that the connection works. Now you can enjoy captivating visuals and immersive theater-quality sound in the comfort of your home. This comprehensive guide will empower you to elevate your home entertainment system with a seamless connection between your projector and soundbar. Enjoy! -Joel S., Techopedia Contributor


A projector and soundbar are a great combination for an immersive home entertainment experience. Whether you’re watching movies or gaming, a projector and a soundbar will deliver larger-than-life visuals and cinematic audio. This guide will show you how to connect a soundbar to a projector for the ultimate home cinema setup.

The best way to connect a soundbar to a projection system is through an HDMI cable. HDMI is a widely used connection option for audiovisual devices because it supports high-quality audio and video signals.

Connect one end of the cable to the projector’s output port and the other end to the input port on the soundbar. Switch on the devices and play content to check for a good connection.


If you are looking to improve the audio quality of your projector without going for HDMI, Optical connections may be an option. Acquire a cable with square-shaped Optical connectors and plug one end into the projector port, and the other into the soundbar’s port.
