  • Set the source of the soundbar to correspond to the external device that is connected to it.
  • Set the source of the projector to the HDMI channel that the soundbar is plugged into.

If you have a soundbar and 4k projector, you may be wondering how to connect soundbar to projector? Here we discuss the problem and offer a solution.

Connecting a soundbar to a projector is usually possible, as long as your devices have compatible ports. However, some limitations to this option can result in getting lower-quality sound than a traditional surround system.

Optional audio formats
Before connecting speaker to a 4k projector you need to think about whether your device supports one of the following formats.

This is the same type of cable you use to connect your game console or Blu-ray player to the projector. This is a digital connection that provides excellent quality and surround sound if both your bar and projector support it.


This is a digital audio cable that uses an RCA or TOSLINK type connection. The sound quality of this connection type is usually very high. If your bar does not have an HDMI input, it will most likely support SPDIF.


This is another digital option that offers superior quality. If HDMI and SPDIF are not options, this should be next on your list.

Analog connection, RCA

This is an analog connection type that can provide decent sound if you have good cables, but if you don’t have any digital options, it should only be on the desktop.

Stereo 3.5mm

This is another analog connection type that works fine if you don’t have any options, but it is limited to stereo and does not provide the highest quality sound.

Bluetooth and WiFi

This is not a physical connector type, but you can find projectors and bars that support it. Since it is a wireless connection, the sound quality may be affected if there is any interference.

Next, we will discuss the specifics of how the above formats work.

How to Connect Soundbar to Projector with HDMI

The HDMI connection is the best way to connect a soundbar to Pericat projector because it offers the highest audio quality than any other cable connection.

So if your soundbar and projector have the HDMI or HDMI ARC port, I would suggest using that connection.

HDMI ARC is even better for the improved sound quality, but that connection is not common in low-budget projectors. So if your projector and soundbar have the luxury of an HDMI ARC port, use a high-speed HDMI cable for the crystal clear audio.

Follow these steps to hook them up:

  1. Switch off both your soundbar and projector
  2. Find the HDMI or HDMI arc port on both devices.
  3. Connect one end of the HDMI cable to the projector, and the other end to the soundbar
  4. Turn ON both devices. If you face any issues, restart both devices. 99% of the time it solves the problem.
  5. For a 7.1 soundbar system, the HDMI ARC will downgrade to 5.1.
  6. If your soundbar is system 5.1, then you don’t need to downgrade it.

What if your projector does not have an HDMI ARC port

  • If your projector does not support HDMI ARC, please purchase an HDMI adapter with HDMI ARC audio output from Amazon.
  • By connecting an audio or video source to the adapter, the adapter will have two outputs, HDMI Normal and HDMI ARC.
  • Connect the adapter’s normal HDMI output port to the projector and the HDMI ARC port to the bar.
  • 4K ARCANA 18GBPS One of the best HDMI adapters on the market.

If you are looking for a projector with a built-in HDMI ARC output port, then here are some recommendations for you

  • Samsung LSP7T Premiere 4K
  • LG HU85LA 4K
  • Aptus CinemaX P2
  • LG HU810PW

SPDIF or digital optical connection

This type of connection is also used to obtain high quality audio. spdif is a digital connection that can be used with either RCA or TOSLINK connectors. Check the input of the bar and the output of the projector to make sure they are compatible with the connection. spdif can use either a round RCA connector or a square TOSLINK connector.

If both of your devices are compatible, follow the steps below to make the connection.

  1. Close both devices
  2. Plug one end of the RCA SPDIF or TOSLINK into the output of the projector and the other end into a compatible input on the bar.
  3. Now connect the input device or devices to the projector.
  4. Turn on both devices.
  5. You can also connect the projector’s audio output to the digital, optical, or SPDIF outputs and connect the bar speaker’s input to the corresponding input port.
  6. If the connection doesn’t work, restart both devices. 99% of the time, it solves the problem.

Simulation of connection

If your projector is fixed to the ceiling, then you will need to purchase a 3.5mm stereo cable long enough to properly connect the cable from the projector to the strip speakers. Here is exactly how to establish the connection.

  1. Close both devices
  2. Locate the RCA port on the projector and connect the left and right RCA cables to the RCA port.
  3. Alternatively, locate the 3.5 mm port on the projector and connect the 3.5 mm auxiliary cable to that port.
  4. The second end of the cable will connect to one or more compatible ports on the strip speaker. Locate the 3.5 mm port or RCA port on the bar speaker.
  5. If you want to switch between the two connections, you can also use the 3.5mm male to 2x RCA male stereo adapter.
  6. Connect your input device to the projector.
  7. Turn on both devices and enjoy.
  8. If desired, you can also set the projector output to analog and set the bar speaker input to analog.

If nothing works, the auxiliary connection, also known as the mini-jack connection, should be your last resort. It is not that good in terms of sound quality.

Wireless connectivity (WIFI and Bluetooth)

Unlike wired connections, wireless connections require your device to be turned on in order to be set up. Your device needs to be paired, not set up with your device as a specific source or output channel.

There are two types of wireless connections: Bluetooth and WiFi. as long as both of your devices are WiFi or Bluetooth enabled, you can connect wirelessly.

 Follow the steps mentioned below to use Projector with Bluetooth speakers .

  1. With both devices turned on, set the bar to pair with Bluetooth according to the instruction manual.
  2. In the device settings of the projector, find the option to connect to Bluetooth.
  3. Find your bar speaker from the list of devices displayed.
  4. Select your bar and wait for it to pair.

Typically, the bar will beep or otherwise indicate that the device is paired before broadcasting audio.

Learn how to do the above, then you will certainly still have some questions, do not worry, the following I will answer for you one by one.

Why can’t I use the projector’s built-in speakers

 There’s nothing stopping you from using a projector’s built-in speakers (if there are any). Leading projector brand BenQ contends that their devices are equipped with Outstanding speakers for top-notch audio reproduction . However, we disagree, as this poses two problems.

First of all, the audio sounds strange. Because projectors are usually placed at the back of the room, the sound waves must travel a short distance to reach your ears. In addition, the sound can hit the back of your ears, making it uncomfortable to listen to.

 The second issue is the actual internal speaker. It is not designed to produce the best audio or widest frequency response. Instead, it is a low-powered speaker tucked into a small enclosure. It plays audio well during demos, but that’s about it.

Ideally, the speakers you use should be located below or above the screen and push the air in your direction so that the sound waves enter your ears at the same time as the video.

What bar speakers are available

 Available in a variety of sizes and options, the bars are a great way to improve the sound of your TV or add speakers to your home theater setup. there are many options under £100, including Sony HT-SF150 .

You can instead use a 2.1-channel system consisting of a strip speaker and subwoofer. The preferred choice for theater rooms, 2.1-channel bars are a great way to get a near-surround sound experience without the cost or wiring.

 We reviewed a range of With subwoofer kits of bar speakers that  Sony HT-SD35 top of the list. Thanks to the built-in S-Force Pro Front Surround technology, it can even provide a virtual surround sound experience.

Can I connect my strip speakers to my media player

If you are using a single media player, then you should be able to connect the bar directly to it. Things can get tricky when you have multiple media players (such as Blu-ray players and Chromecast) because you need multiple inputs on the bar.

For DVD or Blu-ray players, your best bet is probably to use the audio output on that device to feed the bar. Typically, these devices will have a headphone output and a digital audio output. You can use a mini-jack cable or an optical cable.

 Streaming devices don’t have this luxury, as they are too small to accommodate separate audio outputs. Therefore, you will need an additional package called Audio Extractor Converter of the additional suite.

Simply use the HDMI cable to connect your streaming device to the input of the Audio Extractor Converter. Next, use the HDMI cable to connect the HDMI output of the Extractor Converter to the projector and the optical cable to connect the audio output to the strip speakers.

Should I upgrade To a surround sound system

You may find that using a strip speaker is perfect for your room or the type of content you like to watch. For many people, using a 2.1-channel strip speaker with a subwoofer is a good choice because it’s affordable, easy to install and doesn’t take up much space, but the sound quality is excellent.

 However, in order to get the full cinema experience, you need to purchase 5.1 AV Receiver (or 7.2 receiver) and set up the speakers to match. There’s nothing better than listening to your favorite movie, game or sport in full surround sound!

When is it a hassle to connect a Bluetooth speaker to a projector

connecting a speaker to a projector can be tricky. If it works, it will be very simple. If it does not, then you must troubleshoot it. You must check if the problem is with the Bluetooth device or the projector itself. Could be a hardware or software problem?

The trouble with connecting wireless speakers to a projector stems mostly from activating Bluetooth from the projector or making sure the signal from the speakers themselves works as expected. Wireless video is very effective, such as Fire Sticks or Roku Stucks and wireless HDMI kits.

Wireless audio may require more skill than wireless video or even some wired audio. However, when Bluetooth works, it is definitely superior to wired Bluetooth. Fewer considerations for ports, adapters, wire length, cable management and A/V receivers

Should You Connect Your Soundbar to Your Projector

One of the advantages of connecting a soundbar to a projector is that it can be a very portable audiovisual option for a quick and dirty home theater situation.

Most soundbars and projectors are not designed to be all-in-one devices. Many have the ability to serve that function, but may result in compromising on advanced audio and video features. Hooking up all your devices to a decent A/V receiver can ensure that your devices can reach their full potential.

But! If you just need to get up and running now, without purchasing any more advanced hardware, these are all great options to get the sound out of your projector and into your soundbar.


Connecting your bar speakers to your projector 4k is a simple process. By finding the right fit for you and ensuring compatibility between the projector and the speakers, you can take your home theater to a whole new level of cinematic, dynamic sound anywhere, anytime. Of course, if you have requirements for speaker sound quality, you should also consider your needs to find the right bar speaker for you and shorten your decision-making process.
