Soundbar channels: What do they mean - Croma Unboxed (2024)

Soundbars have gradually evolved into one of those must-haves in your home’s entertainment setup. For most users, soundbars enhance the TV experience by delivering the targeted, rich audio experience that TVs’ built-in speakers usually lack.

However, just buying any soundbar isn’t enough, you also need to be aware of some basic audio lingo to make the most of it.One such term is ‘channels’, something you will hear a lot about when it comes to speakers, soundbars and other kinds of audio equipment. But what exactly are audio channels, and how do they contribute to good sound quality? Here’s a deep dive that will leave you a little more knowledgeable about your new soundbar.

What are channels on a soundbar?

The number of channels in a soundbar refers to how many speakers are inside the device, which affects audio quality. An increase in the number of angles at which sound can be projected is facilitated by the channels on a soundbar.

The first number on the channel indicates how many speakers your soundbar has. The second number indicates how many subwoofers are included. This third number indicates whether your soundbar has upward-facing drivers. Although the third number is optional. You’ll find soundbars ranging from 2.0 channels to 9.2.4 channels, which makes them a popular choice for the setup of the audio system or in-home theatre designs.

Understanding soundbar channels

The first number

Your soundbar’s first number indicates how many channels it has. The number “2” indicates the soundbar has two channels on the left and right sides. The soundbar will have left, right, and centre channels if the first number is 3. “5” channel soundbars can also support “simulated” or real surround speakers.

The second number

Whether or not a subwoofer is included with the soundbar is indicated by the second number. A “1” or no number is usually listed for this indication. In other words, if your soundbar has 5.1 channels, you’ll have five main speaker channels and one subwoofer channel.

Due to the small enclosures, very few soundbars come with built-in subwoofers. The wireless version is available in many models and can be placed anywhere. With your purchase, you’ll be able to see what type of subwoofer you’ll get.

The third number

Soundbars don’t often include a third number. But if they do, it is to indicate how many dedicated drivers shoot upwards. In this way, soundwaves bounce off the ceiling and are reflected down to the audience, immersing them in sound.

What is the significance of this? It indicates whether or not your soundbar supports Dolby Atmos surround sound. It is important to note that 5- or more channel soundbars are most likely to have this capability. The number of channels on smaller soundbars is not sufficient to support both upward reflective sound as well as forward-facing sound.

Five types of channels in soundbars

5.1 channel soundbar: This indicates that the soundbar consists of five speakers placed on the left, centre, right, rear-left and rear-right, and one subwoofer.

5.2 channel soundbar: Similar to a 5.1 system, but with two subwoofers instead of one.

7.2 channel soundbar: This indicates that there are seven speakers placed on the left, centre, right, rear-left and right-speaker. The side walls typically contain two more surround speakers. The .2 indication is for two subwoofers.
