Do Projectors Have Sound?

Projectors are in some ways the ultimate home entertainment system as it allows you to get an ultra-large screen size just like at the cinema.  Visuals are obviously important but so is audio.

This begs the question, Do Projectors Have Sound?  

The answer is yes they do.  Most modern projectors come with inbuilt speakers or a host of audio-out options for external speakers.

This article is the ultimate guide on how to get great sound from your projector.

How Do You get Sound from a Projector?

The easiest option for getting sound from a projector is to use the projector’s internal speaker(s).  They work automatically as the HDMI cable will deliver both an audio and video signal.  Internal speakers can offer stereo sound too (as long as there are two speakers in the unit).

The main drawback with internal speakers is that they usually aren’t of high quality or very powerful.  The playback is often tinny with little bass.

The volume, or power, of the speakers, often leave a lot to be desired too as they can sometimes be only 2 or 4 watts in power.  A good set of projector speakers would be 10W which would improve the issue significantly.

If you are trying to fill a large living room with high definition sound, you are likely to be disappointed with these.

However, if you are playing this in a small bedroom and don’t have a massive budget, then you will be pleasantly surprised at what you get from internal projector speakers.

There are also ways of using audio outputs on the back of the projector in order to deliver high-quality sound to external speakers too.  This is what the rest of this article will explore.

Can You Plug Speakers into a Projector?

Another great way of delivering sound when playing your favorite TV show or movie on your projector is by using an existing set of external speakers that are within your living room or bedroom.  Perhaps you already have a HiFi that has a spare optical port?

This would be a great solution for giving you high-quality sound at no additional expense. 

Simply, plug in the optical cable to the optical port on the back of the projector and then connect the other end to the HiFi, select the source, and away you go!

Most projectors also come with an audio-out 3.5mm auxiliary port.  These can be used to send a stereo signal to a HiFi or a set of smaller desktop speakers that you would use with your PC.  This is a super-simple way of delivering audio from a projector.

Check on your manufacturer’s website to see what audio-out options your projector supports.

That said, there are converters that can be used to convert audio signals from one standard such as HDMI to other standards such as Composite, so it is pretty unlikely that you won’t be able to find the correct port/standard to fit your needs.

Do you need a soundbar for a projector?

Although you certainly don’t require a soundbar to playback audio directly from a projector, it certainly is an excellent option.  Soundbars deliver fantastic quality audio in a relatively simple and compact setup.

The rich tones and deep bass available in most soundbars certainly make this a compelling way of delivering audio from your projector.

How Do You Connect a Soundbar to a Projector?

Soundbars by their very nature are much more capable devices in delivering great sound quality for cable TV boxes when compared to inbuilt projector speakers.  They come with a range of different speakers to deliver a rich, well-balanced sound to your living room or bedroom.

The only thing to note is to check what sound outputs you have available on the back of your projector.  Hopefully, you will find an HDMI Out port.

Perhaps the best options though would be to use an HDMI ARC or optical cable to and from both devices.  These deliver the highest quality sound.  Optical cable ports have been common for decades whereas HDMI ARC is a relatively new technology.

Although HDMI ARC ports look exactly the same as normal HDMI ports, they usually have the letters ARC next to the port to denote if it is indeed an HDMI ARC port.

Check on your manufacturer’s website to see what audio-out options your projector supports.  Fingers crossed HDMI arc is one of them.

That said, there are converters that can be used to convert audio signals from one standard such as HDMI to other standards such as Composite, so it is pretty unlikely that you won’t be able to find the correct port/standard to fit your needs.

Can you connect Bluetooth Speakers to a Projector?

Bluetooth is another fantastic option for delivering audio playback from a projector.  Bluetooth offers a super simple and flexible solution for streaming audio to other Bluetooth enabled speakers.

Bluetooth is a wireless standard that is fairly ubiquitous across a range of devices.

Bluetooth is usually a technology that is only found in “Smart” projector models that come with their own operating system and apps, rather than the more traditional projectors.

One drawback to Bluetooth is that it doesn’t work very well over longer distances such as 10 meters.  If your speakers are over 10 meters away from the projector, the audio signal may start to get a bit glitchy.

That said, most living rooms are much smaller in size than 10 meters so this won’t pose an issue for most consumers.

Check on your manufacturer’s website to see if your projector supports Bluetooth.  

That said, there are Bluetooth converters available that can be used to convert audio signals from one standard such as 3.5mm aux to Bluetooth, so it is pretty unlikely that you won’t be able to find the correct port/standard to fit your needs.
