How to Connect a Soundbar to a Projector

Projectors are classics that are never going out of fashion.

I know what you might think. These have been around for ages. It seems like we did everything humanly possible to get rid of them, just to have them come back.

Despite controversies and love/hate relationships with these gadgets, projectors are just getting better.


Superior video quality, sleeker designs, and more compact than ever. We cannot pretend that turning one of your rooms into a private cinema doesn’t sound like a good idea.

Have you thought how comfy it must be to watch movies while laying on your bed, looking at the roof?

These are only a couple of reasons why you’d want your sound experience with projectors to be as good as it gets. So let’s hook them up to a soundbar and transform our homes into private movie theaters.

So Many Ports, How Do I Choose The One That Works Best?

Now, projectors can be a little tricky when it comes to connections. However, they also tend to be very flexible. You just need to find what will work for your projector as well as for your soundbar.

The most common connections will be through a wire. As usual, these connections are famous for being 1-step simple.

HDMI Connections

HDMI should be your go-to connection when you think of audiovisual streaming. It’s known for staying true to video and audio quality altogether.

1. Make sure you have the right twin

HDMI connections became a little tricky when HDMI-ARC showed up. If you’re going out with one twin, you don’t want to mistake them for the other, or things won’t work out (to say the least.)

HDMI-ARC ports are not usual in projectors. This is why you want to be positive that the HDMI cable plugged into your projector heads straight to your soundbar’s regular HDMI port.

Toslink Cables

Yes, we call them optical, but this is their actual name.

Nowadays, optical and high-definition cables are the most common wired connections that you’ll be seeing in multimedia devices. This doesn’t mean they are the only ones available.

1. Connecting while they’re asleep

Trust us on this one. Turn off your projector and your soundbar before you make the connection.

Link both devices with an optical cable and then switch both of them on. Check that your projector is on the digital optical channel.

The One With No Cables

We bet this is the one you were waiting for.

You might not need to be reminded of this, but we’re so used to things working without wires that it sometimes slips our minds.

To get your projector and your soundbar to pair, you want both to support wireless connections, whether it’s Wifi or Bluetooth.

If you’re sure that your devices can play together without cable supervision, then you can get started with the pairing.

1. Power up

For this step, you want the two devices to be turned on. If they run on batteries, simply turn them on. If they need an electrical source of energy, plug them into a socket.

2. Tweak the settings

You want to go to your projector’s settings and enable the Bluetooth connection. The list displayed should include the name of your soundbar.

Can’t seem to find your soundbar?

Maybe it’s because it’s not emitting the pairing signal. No need for despair. Find your soundbar’s pairing button. It will either have a Bluetooth symbol or a label letting you know it’s the one.

Press it and wait for your soundbar to show up on the list of available devices.

3. Let the magic happen

Once you’ve spotted your soundbar on the list, select it and wait for the two devices to pair.

Are Analog Connections Still A Thing?

Technically speaking, an auxiliary cable is an analog connection. So yes, still very much used, although losing popularity as time goes by.

Auxiliary Connections

Despite common belief, auxiliary cables offer surprisingly good quality when it comes to sound transmission.

Yes, we’ve all had cracks and interruptions with these cables over time. But this isn’t due to its capabilities, but because of how it’s built.

Auxiliary cables, particularly the low-cost ones, tend to be made of poor-quality materials. Because of the constant plugging and daily use, they’re easily worn out.

However, this is another one-step solution if the only cable you can find lying around is an old aux. We all know we have a couple of those somewhere.

1. Find it & plug it

It doesn’t get simpler than this. Find your 3.5 mm male-to-male cable and insert it in the corresponding ports of your loudspeaker and your projector.

RCA Connectivity

If you thought auxiliary cables were old-fashioned, you might’ve not even heard about these color-coded wires.

1. Know what you’re dealing with

Everything’s become so simple when it comes to connecting things. Maybe seeing a bunch of colorful cables will freak us out a little. Don’t worry, it’s simpler than it looks.

Once again, make sure that this kind of connection is supported by your devices. If it is, grant your RCA cable and get ready for the fun part.

2. Mix & Match

Don’t really mix them, though. These cables are very straightforward. Find the color around the cable’s end and then connect that cable to the port of the same color.

Once that’s done, you’re all set to start watching movies like royalty.


1. Can I use Soundbar with a projector?

Yes, you can. Soundbars and projectors are perfectly compatible. You will have to make sure, however, that both devices support the same connections.

You can connect them through HDMI, optical, RCA, or auxiliary cables according to your gadgets’ features. There could also be the possibility of a wireless connection.

2. Can you add Bluetooth to a projector?

Wireless connections are not usual in projectors, but that doesn’t mean they can’t be integrated into their systems.

If your projector and soundbar both support wireless connectivity, then you will be able to connect them via Bluetooth audio.

3. Do projectors have audio output?

There are a few projectors designed for creating home-theater experiences. It most likely means that they have built-in speakers.

If the speakers are not integrated, you’ll find the sound comes from wherever you’re streaming the video.

You Won’t Change Your Private Cinema For Anything In The World

Have you ever seen so many connection options for a single device?

It’ll be a surprise to see a large number of projectors supporting the newest wireless options. You’ll also find that some can integrate seamlessly with older connection ports.

It simply does not get more flexible than this.

Enhance your projector’s sound, sit back, and enjoy a private cinema experience at home.
