Basics On How To Build A Home Theater DIY

Posted on 08 October 2018 (0)


There are several ways to build a home theater and a budget can range from just a few hundred dollars all the way into the hundreds of thousands. But in this article, I’m going to focus on a small and moderate budget and I’ll try to list some examples so you can go ahead and check those out to give you an idea of how much you might want to spend. We consulted Los Angeles Home Theater Company: Crescendo Home Theater – Los Angeles about their opinons on Home Theater DIY.
CHOOSE FLAT SCREEN OR PROJECTOR
The first thing you’re going to need is going to be a projector or TV. And there are several budget 4K projectors and TVs out there.
You have lots of good options out there, but before buying the mount, you need to have an idea of exactly how far the projector needs to be from the ceiling so you know exactly which mount to get. You’re also going to need a projector screen. I do recommend waiting until you get your projector so you can see exactly what size screen you want to get. If you have a really tight budget, then you do have the option of painting a wall instead of getting a screen, which, believe it or not, actually does work pretty well.
CONNECTING YOUR HOME THEATER RECEIVER
The next thing on your list is going to be a home theater receiver. You can buy a Soundbar, but home theater speakers usually sound better than the average soundbar, especially if you’re going with the projector.
You also want to make sure that your receiver has HDMI ports on it and that those ports do support 4K and the latest version of HDCP. So you don’t have any issues with 4K video.
SPEAKERS
So when have your home theater receiver, you’ll need some speakers. Speakers are really subjective and everyone has their favorites, but it’s best to listen to the speakers yourself to decide exactly what you like. if you’re doing a five point one setup, then you’ll need a center channel speaker, two main speakers to surround speakers and a subwoofer. If you’re doing seven point one, then you’ll need to get two additional surround speakers. And most rooms are fine with one sub Woofer, but you can even out the room with the second sub if you need it.
HDMI CABLES
The next thing on your list is going to be HDMI cables for all of your devices. And if you’re using a projector then you’ll also need a long HDMI cable. There’s no sense of putting out all this money for this equipment just to let it get taken out from a power surge or a lightning storm. So the next thing that I recommend is a good surge protector. I do recommend getting one with a good jewel rating or you can even get a power conditioner if your budget allows for it.
SPEAKER WIRES
Next on the list is speaker wires and depending on how powerful your speakers are, you may have to get thicker gauge wire, so I usually recommend 14 gauge, no smaller than 16 gauge wire and 100-foot spool is usually enough for most rooms. You also want to buy some banana plugs for your speaker wires since they’ll make your installation easier and cleaner. You’ll also need a subwoofer cable for your sub, but first, you need to know exactly where your sub is going, which we’ll talk about a little bit later.
MEDIA PLAYER
Another thing you’ll need if you’re using a projector is a media player if you don’t already have one, and that’s because unlike a smart tv, most projectors don’t have built-in apps for you to play movies. This is going to be like a blue ray player, firestick, Roku or whatever. Just make sure that it supports 4K if you have a 4K TV or 4K projector.
REMOTE CONTROL
Nobody wants to sit down at a brand new home theater and be forced to use three or 4 remotes. So the last thing on the list is going to be a universal remote. Of course, you have a bunch of options for this, but I personally use the Logitech harmony hub, which is basically a small hub that sits on top of your tv stand and let you control everything from your phone or using your voice using the Google home or the Amazon Echo.
You can even get it with a separate remote if you want. Otherwise, you can buy whatever universal remote you want, but I do recommend getting one that lets you set up activities so it’ll automatically turn everything on or off with one button.
HOME THEATER INSTALLATION
When you have everything,  you’re ready to get started with the installation. If you’re setting up a projector, I do recommend that you start with that first. Before you mount the projector is best to hold it into place where you think you want it to go so you can easily see what size screen you want, what kind of ceiling mount you need, and how long are HDMI cable needs to be, and to measure your screen, make sure you’re measuring diagonally. If your projector has a zoom that it might be best to set the zoomed out in the middle so you can easily adjust the image to fit the screen perfectly.
As far as running the HDMI cable between your projector and your receiver, you can either run it above the ceiling in which you may need professional installation for, or you can run it on the ceiling using the raceway, but it’s completely up to you.
HDMI CABLE HOOKUP
Once you have your projector mounted, your screen mounted and your HDMI cable run to your receiver, it’s time to get started on wiring up your home theater receiver. So the first thing you’ll do is connect the HDMI cable from your projector to the HDMI output on the receiver. Then you’ll connect all the other components to the open HDMI ports on the receiver, and I do recommend snapping a pic of the back of the receiver so you can see which cables are using what input since you’ll need this information later. So now you’ll want to position your speakers and run your speaker wires.
There are several ways to set up your speakers depending on the size and shape of your room, but the center channel should be directly under your screen and the main speaker should be at least six feet apart on the sides of your screen. And as far as your surround speakers, some people like to put their surround speakers up high, but Dolby recommends putting them at or just above ear level. It’s really up to you, but just don’t be scared to experiment with what you think sounds best.
WIRING SPEAKERS
Once you have all your speakers in place, go ahead and use your wire cutters to strip the wires and put your banana plugs on and your receiver should be labeled to indicate exactly where you plug in each speaker. Just make sure you don’t mix up the positive and negative on both ends.
SUBWOOFERS
When it comes to your sub Woofer, if you have more than one place in the room that it can go, then it’s best to do what’s called the subwoofer crawl. There are several youtube videos about this, but basically, you want to put the Subwoofer in your seat and play something through the Subwoofer. Then you crawl around on the floor where you think the sub might go and whichever play sounds best is where you put the sub. Once you get it in place you can go ahead and wire up the subwoofer cable between your sub and your receiver. Most subwoofers have at least two knobs on the back of them. One is for the gain and the other is for the crossover. I personally would recommend sending yourself woofer’s crossover around 80 Hertz depending on how big your main speakers are. And I usually set the subwoofers gain knob around halfway and you can always raise or lower it later if you need to.
CALLIBRATION
Once you have everything all wired up, I recommend that you use a setup, Mic, if your receiver came with one, this is going to let the receiver automatically boundless out the speakers for your room, and the last thing you need to do is set up your universal remote if you haven’t already.
REMOTE AND RELAX
Setting up a universal remote is going to make it easy for anyone to sit down in your home theater and press one button to turn everything on and press one button to turn everything off. So when you’ve got everything set up to your liking, it’s time to sit back, relax and enjoy a movie!!
