Home theater systems Technologies: The definitive guide


Home theater systems Technologies: The definitive guide

People buy home theater for aesthetics or functionality. And, there is a third group of people who buy it for both reasons.

The problem most people have is the difficulty in understanding all the terminologies used in describing a home theater.

For starters, you probably don't know the meaning of "Surround Sound" and how it affects the sound of your home theater.

The same applies to a whole lot of other terms we've come to accept as usual. Understanding these technologies and terminologies will help you buy better products.

This article is a definitive guide for the most critical details in a sound system. Let's ride!

Popular Home Theater Sound Systems Technologies

Surround Sound

Surround sound is a sound effect that channels audio directly to the listener from different angles.

The sound comes from the front, sides, and back of the listener.

Imagine you're in a room with speakers on all edges of the room; that's how it feels.

Surround sound is so unique that the combination of all the speakers doesn't generate noise.

The setting appropriately complements each other.

A perfect example of this setup is in movie theatres. The surround sound effect is the idea behind having five speakers and a subwoofer in a home theater system.

If you want to get the most out of this, ensure you hire the services of the right home theater installer.

5.1 Channel System

Five-point one (5.1) Channel System refers to the default configuration of home theater systems.

If you want a surround sound effect, your home theater installation should have the following:

  • Two speakers in the front (right and left)

  • Two surround speakers at the back (right and left)

  • One speaker at the front (center). It could be directly on your TV stand or console

  • One subwoofer close to the TV console

This entire setup consists of five speakers and one subwoofer. Hence, the term "5.1 Channel System."

7.2 Channel System

A home theater installation with a 7.2 channel system is very similar to a 5.1 system except that the former has more speakers.

The 7.2 channel system has seven speakers and two subwoofers in the following configuration:

  • Two speakers in the front (right and left)

  • Two surround speakers at the back (right and left)

  • Two surround speakers at the sides (right and left)

  • One speaker at the front (center)

  • One subwoofer at the front

  • One subwoofer at the back

The home theater installer is responsible for balancing the speakers and subwoofers to create a fantastic surround sound effect.

Dolby Atmos

Dolby Atmos is a mind-blowing sound technology that heightens sound, making it seem three-dimensional.

It's very similar to the 5.1 and 7.2 surround sound system in its configuration.

But Dolby Atmos went the extra mile by providing two to four speakers that resonate downward from your ceiling.

At first thought, you may think it will be noisy.

On the contrary, the setup creates a lovely harmony that gives life to every distinct sound you hear from the home theater. You can configure the Dolby Atmos technology as 5.1.2, 5.1.4, 7.1.2, 7.2.4, 9.2.4, etc.

Don't get confused. The figures are similar to those of surround sound; each last digit number is the ceiling's speakers.

A home theater installer will give you a practical expression of the setups in line with your peculiar needs.

4K Resolution

4K resolution is not commonly associated with home theater installations. It's a video technology that refers to a horizontal display of approximately 4,000 pixels.

It comes in different variations, such as "3840 × 2160" and "4096 × 2160."

In the two instances, notice that the horizontal pixels are approximately 4,000; that's why it's called "4K."

When you combine a 4K resolution with a terrific home theater, the result is paradise.


Components of a Home Theater System

The different components that make up a home theater system add brilliance and style in their peculiar way. They include the following:

Projector or TV Screen

A projector or TV screen is as simple as it sounds. It's the display output of a home theater system.

A couple of home theater systems come with a television screen. But most home theaters don't. It would be best if you bought a screen with a good pixel ratio.


Speakers are the sound output of a home theater system. They come in various shapes and sizes, and of course, different features.

Audio Receiver

The easiest way to understand an audio receiver is to think of it as the home theater's central processing unit. It's a device that receives audio, processes, amplifies, and sends it to the speakers.

Smart Remote

A smart remote gives you control over your home theater setup. With it, you can carry out several actions on the sound system, including volume adjustment, music selection, power off and on.

Lighting Control

Some home theaters come with lighting control that integrates with the lightning of your house. To fully implement this, you will need a seasoned home theater installer that understands the technology very well.

Shade Control

A shade control and lighting control is the perfect combo you need to create a studio effect. While lighting control adjusts your light, the shade control serves as an automated window.


Everyone deserves quality sound; everyone deserves a home theater. Now you know what different home theater technologies mean, it's time for you to go out there and make an informed buying decision. Then, enjoy the brilliance of good sound.
