Since most projectors only have a stereo audio output, you’ll only be able to acquire 2.0.
There are no surrounds or subs.
You’ll need an HDMI input selector with audio extraction to give a 5.1 digital audio output to get surround sound.
This would be connected to a 5.1 analog out optic converter.
How do projectors and speakers communicate?
Each projector has its own set of inputs and outputs, and depending on the equipment you’re using, you can connect a projector to 5.1 speakers either directly or indirectly.
The built-in speaker or attaching the 5.1 speakers directly to the projector is the most common projector installations.
More complex home theater systems, on the other hand, will typically require an A/V receiver to handle the visual end and send the audio signal to the speakers.
If you’re thinking of putting together your own home theater system with a projector, have a look at this step-by-step guide before you go purchasing.
Because no two perfect home theaters are the same, don’t try to copy someone else’s design. It just takes a little more thought to make one that is truly unique to you.
Examine your surroundings.
When you go from a television to a projector in your home theater, you’ll probably need to rearrange some things.
Before you do anything else, you’ll need to place the display you’ll be viewing and the projector itself.
When you set up a projector-based home cinema, one of the most significant distinctions is how you think about light.
Consider your stationary light sources, such as windows and fixed lighting fixtures. The brighter and crisper your image is, the less light pollution reaches the projector lamp and screen.
The second significant distinction is that you are not restricted to specific image sizes. Most projectors can produce a wide range of screen sizes, ranging from 30” to 300” depending on how the lamp is positioned and the distance between lamp and screen.
The bigger the screen, the larger the gap between the lamp and the screen, then the more sensitive the image is to light pollution. If you want a big screen in a small place, you’ll need a relatively brief projector, which usually means paying a little more money.
Consider where you’ll sit. The projector’s light beam must be able to reach the screen without being impeded.
Consider how you’ll raise the projector beam above everyone’s heads if you wish to place your couch between the projector and the screen.
For long-term installations, ceiling-mounting is the safest solution, but tall shelves and other furniture can also be useful.
Select the appropriate display.
You can project the image from a projector directly onto a wall or hang a white bedsheet if you’re in a hurry. However, if you’re putting together a whole home theater, it’s worth devoting a chunk of your budget to a high-quality screen.
The screen’s relevance in your watching experience cannot be overstated. There aren’t many blank, white walls the size you’ll need for a projection screen in most homes. Many projector screens are also designed to boost contrast or increase image quality in some way.
This can be quite useful in rooms with a lot of ambient light or other restrictions. Others include micro-perforations that allow you to place 5.1 speakers beneath the screen for full surround sound.
Make a plan for how you’ll receive your content.
When you switch from a TV to a projector, this is the part of your home theater that will probably stay the same. The trick is to purchase a projector that is compatible with your preferred method of watching TV and movies.
The basic HDMI input found on all home theater projectors will suffice if you usually view stuff through a streaming stick, gaming console, or set-top box. However, not all projectors have VGA, MHL, or wifi streaming capabilities.
Look into your sound options.
The 5.1 speakers through most TVs are strong enough to fill a typical living room with enough sound. Projectors, on the other hand, are smaller devices with 10-watt speakers that don’t have the same output. The fact that projector heat bulbs require fans to cool them exacerbates the problem, and all these fans create their own noise.
External 5.1 speakers aren’t required if you’re using a projector, but they’re recommended if you’re utilizing a TV-based home theater system. If you already have one, ensure sure the projector you buy is compatible with it. The majority of projectors will provide a 3.5mm audio output at the very least.
The majority of projectors will provide a 3.5mm audio output at the very least. If you have an extra HDMI port, you can utilize it to connect your 5.1 speakers to your computer via Bluetooth.
Make a budget and purchase your equipment.
Make a list of everything you’ll need to complete your home theater. This will inform you how many ways you’ll have to divide your entire budget.
You’ll need a projector and a screen at the absolute least. You may also require a sound system as well as peripheral devices such as a ceiling mount or additional wires.
The projector will most likely be the most expensive part of your budget. They range in price from just over a hundred dollars for a basic model to $2,000 or more for full-featured 4K Ultra HD variants.
A projector with a 1080p resolution in the $500-$1,000 range should be enough for most homes.
Surprisingly, screens can be found in the same price range. A simple white screen with a size of 120” to 150” should be enough for most households, and you can get one in the $50-$100 range.
The only reason to pay more is if you want extra features like a high-contrast screen or the option of having 5.1 speakers hidden below the screen.
The price of your sound system is entirely up to you. If the quality of your television speakers is satisfactory, a modest 2.1 surround sound system (two bookshelf speakers and one subwoofer) should suffice. For as low as $50, you can get a good set.
Don’t overlook ancillary items such as ceiling mounts and wires. Individually, these don’t add much to the cost; most ceiling mount systems cost between $25 and $50. But keep in mind that this equipment will need to be installed as well.
If you’re not a proficient DIYer, this is a job you should hire a pro to complete, especially if you want to run wires through walls or interact with your home’s electrical system in any way.
All of the parts must be connected.
When it comes to the setup, the question of whether or not you require expert installation is a huge one.
You should be able to mount the projector yourself if you aren’t already doing so. Even the most basic mounting systems can be completed by someone with only a little home repair and electrical skill.
Before you begin, double-check that you have everything you’ll need to be purchased and ready to build.
Everything will go much more smoothly if you have all of the necessary cables, screws, and tools before starting your job.
You should also devote some time to reading the handbook that came with your projector.
Connecting things in a specific order can sometimes help ensure that everything works properly after you turn on your system.
This is especially true for ceiling-mounted systems, as tinkering with them after they’ve been installed can be a pain.
Install the projector.
To bring the image from your projector to the proper size and exactly centered on the screen, you’ll probably need to do some image alignment and modification.
If you’re installing the projector, do this first so you can make sure it’s in the appropriate spot before you attach the hardware.
To get the projector to the correct height, mount it on top of a ladder until you’re ready to make the positioning permanent. If the projector’s location is set due to space constraints, you might instead wait to permanently attach the screen and vary the image size by moving it around.
The kind of image modifications you can make differ for every projector, however, they can include zoom, alignment, and inversion options.
Many projectors have keystone adjustment, which allows you to tilt the projector away from the screen without distorting the image. If yours doesn’t, you’ll need to make sure the lens is pointed directly at the screen.
Some projectors come with an onboard wizard that guides you through the process of configuring your settings, sound, and image. It might or might not be as simple as connecting everything to the appropriate ports. You’re probably not the only one who gets stuck or bewildered.
There are a plethora of video lessons available to assist with the individual oddities of different models or configurations, and at least one of them will likely have the answer to your concern.
Complete the installation.
Hang your screen securely, attach your projector if necessary, and locate a long-term home for your 5.1 speakers. Make sure no cords or wires are dangling from the ceiling, hung across pathways, or anyplace else they could cause a hazard.
Examine your audio and video sources.
Double-check that everything is connected properly before calling it a day. It’s a lot less frustrating to uncover and fix any problems right immediately than it is to find out about them while you’re watching your favorite show.
Play a fast game on your PlayStation, or start a Netflix show on your FireStick—do whatever you normally do to enjoy your projector. Before you call it a day, make sure the audio and picture both are functioning and aligned on all input channels.
The most frequent methods for connecting a projector to 5.1 speakers are as follows:
- Standalone stereo 5.1 speakers: This straightforward method employs a pair of stereo speakers, which are usually powered.
- A soundbar is effectively a set of powered 5.1 speakers combined into a single unit, so it’s a similar alternative.
- Some projectors include Bluetooth capabilities, allowing you to connect to any Bluetooth-enabled speaker.
- A/V receiver: This is a more difficult option to choose. The receiver connects to your streaming device, DVD or Blu-ray player, or other media, as well as the 5.1 speakers, and the receiver outputs video to your projector. Other components, such as an amplifier, could be involved as well.
You can connect a projector to 5.1 speakers using the following sorts of connections:
- RCA connectors: You can attach stereo speakers to your projector if it has RCA connectors. One cable is required for each 5.1 speakers. RCA video inputs, one for composite video and three for component video, may be available on your projector.
- Stereo audio jack: This is the same sort of audio jack that has been around for decades and is still used for headphones and earbuds on many phones. A stereo signal can be sent to a set of solo speakers or a soundbar using a single 3.5mm TRRS connection.
- There have been no additional cords or components to purchase if you have a Bluetooth-compatible 5.1 speaker and your projector supports Bluetooth. It’s a wireless link. Audio over Bluetooth, on the other hand, is often of worse quality than the other methods.
How to Connect a Stereo Speaker to a Projector
If you really want to connect your projector to stereo sound, you should purchase powered speakers specifically intended for this purpose.
A/V receiver or amplifier-connected speakers will not operate. You should also look at the 5.1 speakers to discover what kind of associated with the higher they have.
You may well be capable of connecting with a single 3.5mm audio cable if the 5.1 speakers are wired together, but most of these speakers require separate left and right channel RCA connections.
You’ll need a 3.5mm to 2x RCA audio input splitter if your projector has only a 3.5mm audio output and your 5.1 speakers have only RCA input.
How to connect a projector to stereo sound is as follows:
- Place the 5.1 speakers where you want them and plug them in or put the batteries in them.
- Connect an audio connection to one of your projector’s audio output options.
- Connect the cable’s opposite end to your speakers.
- Your projector’s volume should be adjusted.
As previously said, putting together a home theater with a projector is simple.
It’s the most cost-effective option to have a large screen, even if you opt for high-end equipment and skilled installation.
Knowing what to expect in terms of expense and labor before starting your home theater installation will protect it from getting overwhelming.
