How To Connect A Speaker To A Projector for Best results

How To Connect A Speaker To A Projector for Best results, Silent movies are no longer popular. The sound must accompany moving pictures if they are to enjoy films and television programs. For a cinematic experience, sound must be synchronized with the action when you project video using a digital projector. How do I connect soundbar speakers and Bluetooth speakers to my Projector? The key is finding a suitable audio connector device that will allow you to link the Projector and speaker.

Be aware that some projectors are incompatible with Bluetooth speakers due to their lack of Bluetooth. Keep in mind, however, that you can still use the sound from your notebook computer or HDTV if you cannot get sound from the Projector.

It’s not easy to set up a projector system. You may wonder when the fun will end so you can relax and enjoy your projector setup. One big problem must be solved: getting the video sound from your Projector into your speakers. It can be quickly done in two ways:

To get the sound from your projector to the speakers using an A/V receiver:

  1. Power off all the equipment and plan the arrangement
  2. Using an HDMI cord, connect your audio source to an A/V receiver
  3. Connect the A/V Receiver to the speakers
  4. Power on and test

To get the sound from your projector to the speakers directly:

  1. Power off all the equipment and plan the arrangement
  2. Connect the speakers to the projector’s audio port (a 3.5mm jack, a set of RCA jacks, or Bluetooth)
  3. Connect the speakers using the audio cable or by Bluetooth pairing
  4. Power on and test

You might think it’s easy. It can be straightforward if you have the right equipment and cables and know how many channels you want to create. Once you have this information, you are ready to go. All you need now is the details. Let’s get started:

How To Connect A Speaker To A Projector

Method 1: Connect your Projector to Speakers using an A/V Receiver

Step 1: Power off all the equipment and plan the arrangement

This step may seem obvious. It is easy to unplug everything and move it around, except that your projector might already be mounted. It will be much easier to plan your equipment arrangement in advance.

Planning the system is a great way to make your setup reliable and clean. You will need to start over if you don’t plan.

You probably know exactly where the projector should be placed. But, likewise, it would be best if you had an idea of where the screen will be identified and the area where you’ll be sitting.

It will determine the location of your speakers. It is crucial to decide where the A/V receiver will be placed and where speakers will reside permanently if you want to make 7.1 channels of sound with an A/V receiver.

Step 2: Connect your audio source to the A/V Receiver

A/V Receivers are intimidating. They are larger than most house pets and will likely have more ports than your other setups. It’s all about connecting the right things.

You can connect your audio source to the A/V receiver using an HDMI cord from the source, or a SPDIF cable from your projector.

Step 3: Connect the A/V Receiver to the Speakers

Once you have sorted the receiver input, you can focus on the speakers. Then, you can connect the appropriate speaker channels to the receiver and the speakers.

It should be done before you mount everything so you can check the connections and speakers before installing them. This troubleshooting step is worth the time and effort spent installing surround sound systems.

Step 4: Power On and Test

You’re now ready to plug in the power cables required for everything (the A/V Receiver, projector, and speakers). Now that you have all the power cables (the projector, A/V Receiver, and speakers) plugged in and are ready to test your A/V receiver setup. Now you can turn it on and stream something.

Don’t panic if you don’t hear any sound immediately. You might have a muted projector or cables that aren’t working correctly. These issues can be fixed by finding the remote to your projector or using a step ladder to access its volume buttons. Next, go around to the speakers. Take the audio jacks out and in. You can also do this with your projector.

If the system still isn’t working, you should check the video source. It should be sending the audio file along with an HDMI cable. If this is the case, then start investigating it. Sometimes it is as simple as the audio volume of the source video, such as when projecting from a computer.

Method 2: Connect your projector directly to speakers using audio Cables or Bluetooth

How To Connect A Speaker To A Projector

Step 1: Power off all the equipment and plan the arrangement

This step is more accessible than the A/V Receiver method. In addition, you will have fewer speakers to deal with since projectors below a 4-digit price tag won’t support 2-channel options via their RCA or 3.5mm jacks.

If you use the direct connection method with these cables, you still need to plan the placement of speakers and cable management.

Even if you have a simple setup like a soundbar that fits under the screen, there will still need to be at least one cable. An alternative is to use a Bluetooth speaker instead.

You won’t need to hide any connection cables (though you may still need to use a power cable), but wireless connections will simplify this process.

Step 2: Connect the Speakers to the Projector’s Audio Port (3.5mm Jack, Set of RCA Jacks, or Bluetooth)

It is easy enough. You have now set the speaker and projector locations and found a way to connect the cables in a visually acceptable manner. Now you need to plug them in. What could go wrong?

You may have noticed that most audio equipment ships with cables measuring between 3-6 and 20 feet. However, you will likely need something more prolonged than that to complete the job. It is fine.

There are two options if you have chosen a Bluetooth connection. The first is to get a projector with Bluetooth built-in. It will make the process much easier.

There are many options available to connect your projector with Bluetooth if it doesn’t already have it. For more information, refer to [INSERT LINK]

Step 3: Connect the speakers to the other end of the audio cable, or pair your Bluetooth Speaker

This step is easy if you use a central audio bar such as the Vizio SB3821 (on Amazon). This step is easy because you don’t need to manage cables except for A to B.

It looks like you have dual speakers, but it is still straightforward. First, you can take your two RCA cables and separate them however you like. Then, connect each speaker to your room in a way that suits your aesthetics.
The setup of Bluetooth should be easy.

If your projector has Bluetooth built-in, go to the pairing menu and then set your speaker into pairing mode. The rest should be easy. If your projector does not have Bluetooth built in and you have an aftermarket option, refer to the instruction booklet to learn how to connect it with your speaker.

Once you have everything in place and the audio cables or speakers paired, you can finally power it up and test it.

Step 4: Power On and Test

After you’ve paired the Bluetooth speaker and all cords are plugged in, turn everything on to see what happens. Refer to the A/V Method above if you are unable to hear any sound through your speakers.

Check all cables and source volume settings. To test a Bluetooth speaker, un-pairing and then re-pairing it to another source is advisable.

Non-Bluetooth Wireless Options

Always be open to new ideas. Projectors almost always have an audio jack. It will almost always be the cheapest and most direct solution to your audio problem. However, cable management issues can be a problem that could deter you, as we have discussed.

You might think there is a more straightforward way to protect your projector onto a pair of speakers wirelessly. Unfortunately, it is not a one-size-fits-all solution. You can remove the audio from the HDMI source projector using a dedicated extractor such as (Amazon).

Some projectors may already have Bluetooth built-in. Some projectors might be equipped with advanced internals that stream to Sonos speakers or can be wirelessly made wireless using an aftermarket option such as this wireless RCA receiver/transmitter kit (on Amazon).

These things still exist. However, at best, they add another subsystem to manage and, at worst, introduce another system that could fail. In addition, each wireless transmitter/receiver option requires its power source and can complicate already overtaxed power outlets.

The best way to “go wireless” is not to use complicated wireless options introducing new equipment. Instead, force the system to become wireless by requiring fewer wires connecting to the video source (the Xbox, the computer, etc.). You can connect directly to the speakers. It will allow you to reduce the amount of material transported to the projector and back.

Why You Might Want To Use An Audio/Video Receiver

Finally, there are people out there whose home theater projectors are as expensive as a used sedan and who intend to use them for 4k content with matching sound quality (such as Dolby Atmos or a 7.1 channel stream). You are almost certain to be this person. Your streaming box, no matter what it’s delivering, should connect directly to an audio/video receiver.

You might be tempted to believe that an A/V receiver is just another step and another failure point, despite the fact that you have read about them both. There is no denying that a projector will produce two channels of sound, as it was designed to project.

You can’t expect your projector to manage the HDMI cord and 7.1 surround sound files.The A/V receiver is the best option if you are looking for the highest quality, even though it may take more time to set up.

Projector Audio Connection Types

  • 3.5mm: Patented in 1884, this format of the phone jack is the most common way to connect your speakers and projector or through any available port. This connector is used to connect headphones and laptops. However, it can also link smartphones and music players to their projectors, stereos, AVRs, and sound systems.


  • Component Audio or Composite Video: The component video (YPbPr) and composite standards include stereo audio. One plug is for the left speaker, and one is for the right. It is usually an L and R connector. It produces better sound quality than mono sound for one speaker.


  • Optical and TOSLINK: Before HDMI, there were TOSLINK (or optical cables). To deliver high-quality digital audio streams, the TOSLINK standard uses optical cables. This cable is superior to the 2-in-1 HDMI cable. It can transmit sound from DVD and CD players, computers, and DAT recorders to an audio receiver for decoding up to two uncompressed or compressed PCM channels.


  • Bluetooth: Bluetooth technology allows wireless audio transmission. It is a huge boon not only for smartphones but also for home projectors. This wireless standard will enable you to connect two Bluetooth-compatible devices on smartphones, laptops, and computers. The Bluetooth speaker can be used to replace or amplify your built-in speaker. It can also connect to any Bluetooth-equipped device.

Advantages and Disadvantages of Connecting Audio Devices to Your Projector 

Modern 21 stprojectors, released from the late 2010s to the 2020s, have an audio option and built in speakers that allow for more control over sound quality. The sound can be sent from your projector speaker or through an HDTV connected to a cable box, BD player, or both.

Here are some ways your projector can be connected to various audio devices. Although it varies from one device to another and from brand to brand the process is similar.

  • Connecting Stereo Speakers to Projectors: This is quite simple. Some speakers can be linked together, while others have their own audio connectors. You will need to split the coaxial cable or audio jack between them. Most speakers only require one audio port.
    • Simply Plug It In: To connect most modern projectors to stereo speakers, you will need a projector that has a 3.5mm, composite/component or TOSLINK cable.
    • Mandatory Speaker Connect: If the media source device does not have speakers (e.g., you use an Amazon Fire TV Stick to replace an HDTV with a cable box and/or a PC with speakers), then stereo speakers are required.
  • Connecting projector to sound-bar amplifier: A sound-bar is a speaker that looks like a bar and provides sound. These soundbar amplifiers are often sold as sound-bar amplifiers or amps. They enhance the sound from built-in speakers on a projector, HDTV or HDTV.
    • Speaker versus Amp:An amplifier does not “mute” your projector, HDTV and/or computer so that they produce the only sound. Instead, it amplifies or enhances the sound by keeping the soundbar and original speakers on.
    • The same rules apply: A soundbar functions essentially the way a stereo speaker does, but uses fewer plugs. Use the ports and connectors that your projector and stereo speakers have to make this audio connection. Don’t connect them if they aren’t available. It covers connections from 3.5mm (phone Jack) to HDMI.
  • Connecting projector to A/V receiver:An A/V receiver, also known as AVR, is an electronic component that’s used in home theaters. It is designed to receive audio and video signals from multiple sources and process them to create loudspeakers and route the video signals to devices such as projectors, monitors on PCs and HDTVs.
    • Turn off, connect, and turn on: First, turn off both devices. Connect the audio cables to the sound port, or “Audio Out”, on the projector. The audio cables’ connectors should be inserted into the AVR’s “Aux-In” port at the rear. You can now turn the AVR on.
    • Click the Source Button: An AVR has a button called “Source”. It should be pressed until the word “Aux” appears on the control panel. You will know that you have completed this step correctly if you hear the projector emit a sound or alert to the AVR.
  • Connecting projector to Bluetooth speaker:This option is only available if the projector has Bluetooth connectivity. You won’t be capable of linking your Bluetooth speaker with the projector if it isn’t. You can’t use it if your PC has Bluetooth.
    • Both Bluetooth is turned on: First, ensure that no other Bluetooth devices exist. Turn on your Bluetooth speakers. Next, open the settings menu of your projector to turn on Bluetooth. The projector should detect nearby speakers automatically. Connect to the speaker by selecting it.
    • Troubleshooting: If your projector is not connecting to the Bluetooth speaker, turn off and turn on the Bluetooth as well as the speaker to reset the signal and induce detection. You should hear a confirmation sound to confirm that it is connected, such as in the case with Raycon E25 Bluetooth headphones.
  • Connecting a Projector to a House Theater Sound System:It is more complicated to connect a whole house theater system than simply connecting the speakers to stereo sound, or one soundbar or Bluetooth speaker to mono sound. An AVR, or similar device, can reroute audio and video signals to the correct channels, while connecting to various splitters, switches or matrix switches.
    • Matrix Switch, Switch, andA splitter allows you to connect one media source device to two displays or one display and one audio device, if it is HDMI. You can increase the number media source devices that you can connect to your projector or HDTV with a switch. For more complicated home entertainment connections, a matrix switch is a combination.
    • AVR and Switches and splitters:An audio matrix switcher can be an AVR. It divides the video signal to display devices and the sound to the speakers, stereos or entire sound system. You can use it as part of a matrix switching system to make it easier for audio to be linked to your speakers.
  • Wired or Wireless Audio Connections: When connecting wirelessly, you will mainly use the 3.5mm headphone port to connect speakers with the port on the projector or video device. Wireless audio can be connected via Bluetooth, but also via your Wi-Fi network. This will allow you to send your video signal using apps and features on your smart projector.
    • Splitter or Bypass: If you have an old soundless projector with VGA ports and cable, you can then connect your speakers to the source media (an HDTV/PC). Splitting the HDMI signal can be done via a converter or splitter.
    • Miracast Chromecast, Chromecast or Airplay. Or Wireless Casting: You can wirelessly split audio and video signals using Miracast Chromecast, Chromecast and Airplay (via Apple TV), and similar. The video will be connected to your smart projector using a Bluetooth speaker and the audio to the Bluetooth speaker. Be aware of latency and sound syncing issues


Conclusion on How To Connect A Speaker To A Projector

There you have it. You are now free to move on to the final steps of the projector setup process. You’re now ready to relax and enjoy your home theater setup that you have been working towards.

To improve the audio quality of your projector’s audio output, connect external audio devices. Just like your HDTV or PC, your projector’s ports will determine the devices that can be connected to it. Different external audio devices will require different connections depending on the ports they have and the ports on your projector.

Some allow wireless connection, depending on whether the projector is “smart”, that is, it can connect to Wi Fi and download apps.
