How to Connect Sound Bar to a Projector 2022 [Updated}

connect soundbar with projector

Recently I had a meeting at my office, and they asked me how to connect sound to a projector. Although I was owning the best projector for conference room, still I didn’t know! So I decided to do some research, and here’s what I found; for those who asked themselves that question. No matter if you buy a projector under $150 or a projector under $2000, it is necessary to know how to connect sound to a projector?

So let’s start with the basics:

What is a Projector?

A projector is a device used to project images onto a screen or other surfaces, be it in a movie theater or the home.

To make this possible, the projector is connected to an amplifier which turns the input signal (usually from a DVD player) into an amplified sound that can be heard over other sounds. The image light will shine through lenses and then through a device called a lens. The lenses will then focus the light onto a closed mirrored box containing the film or slide with the image.

The sound signal of this image is then projected through speakers so that we can hear what is going on in our movie. The most used frequency (pitch) for audio subwoofers is between 60 Hz and 200 Hz.

Most of the time, a projector is connected to a TV set (using an RGB connection) so that the sound will be amplified by their built-in speakers or through an external amplifier. It is not always the case as other devices can be attached to projectors.

So back to your original question: How do you connect sound to a projector? Here we go:


  1. Sound system with cables and power source
  2. Projector (Or any device that has a video output)
  3. PC that can play the sound

Basic Steps:

  1. Connect the audio out socket of your sound system to one of the input sockets on your projector or other video playback devices.
  2. Play the sound on your PC, and you’re done!

Suppose it’s hard to find out how to connect the audio out socket of your sound system to one of the input sockets on your projector or other video playback devices. In that case, you may want to buy yourself a DC To AC Power Adaptor Converter. Just plug in the DC plug of the converter into your power outlet, and you can use it to turn your wall socket into video output.

How to Choose the Right Sound System?

If you have an old speaker laying around at home, then you’re all set. If not, you may want to get one from a nearby electronics shop. Look for something that can connect to your computer’s sound output port and video input port (We’ll call this thing a VGA-Audio Converter). Depending on how much you want to spend, your ideal choice maybe these two from JBL: DC-DLS1 or DLS 2. But if you’re looking for something cheaper, look at the Hippo brand. They can still do nicely with a more affordable price tag.

How to Connect an External Speaker?

The above two JBL speakers are made for computers. So you need to connect the DC-DLS1 or DLS 2 to your computer and play sound as usual. Once that is done, you’ll be able to use these two devices as external speakers connected to your projector or other video playback device.

How to connect your computer sound to a projector?

To make this setup work, you need to have the following:

  1. A projector or any device that has a video output
  2. A PC that can play the sound 3. An external speaker

If step #1 and step #2 are already checked, then you’re already good to go.

If step #3 is not checked, then you can either connect your PC to your external speaker first or play the sound there, or you can buy another sound system that has a video output on it.

Can you connect a Bluetooth speaker to a projector?

No. You cannot secure a Bluetooth speaker to a projector or any video playback device with a different power source. To make it work, you need to have the following:

  1. A projector or any device that has a video output
  2. An external speaker
  3. A PC or laptop
  4. A DC To AC Power Adaptor Converter

For everyone who needs a more detailed procedure, the steps are as follows:

  1. Connect the external speaker to your projector or other video playback device.
  2. Plug in the DC plug of your converter into an outlet.
  3. Let your PC play some sound, and that’s it!!

Your external speaker will now be connected to the projector. Here’s a YouTube video that can help you make the connection in case you don’t understand what I’ve said above:

Note that these methods will work on other devices, too, such as smartphones or tablets with SD card slots. Just play your sound on these devices, and the speakers connected to it will be able to produce the sounds via the projector’s input port.

Is there a Bluetooth Projector?

The answer is yes! There’s a Bluetooth projector called the LG PH300. It’s tiny and pocketable, while it also supports wireless video streaming from your phone or tablet. You can quickly hook this to any TV by connecting it to its HDMI port; then, you can immediately start telecasting videos wirelessly via Bluetooth. You’ll need to download the LG PH300 app on your iOS or Android device, though, because it only comes with a wired remote control.
