Today I'm going to talk to you about home theater sound channel. There are 5.1, 7.1, 11.2, 5.1.2, etc. What does that mean? If you think of a channel as a speaker, the first number (for example, 7 in a 7.1 system) = the number of speakers, or seven speakers in this example. .1 indicates whether the system has subwoofers, so.1 = one subwoofer in system 7.1. The last number, such as.2 in the 5.1.2 system = how many Dolby Atmos speakers are in the Settings. So 5.1.2 home theater means 5 speakers, 1 subwoofer and 2 dolby panoramic speakers. The more channels you have, the more speakers you can add. The more speakers you add, the better and more realistic the sound. At a minimum, you need 5 channels... But it is recommended to get at least 7. With 7 channels, you will experience the most advanced digital cinema at home: large, thrilling, compact, theater acoustics.
A good old stereo system is now called 2.0 (two channels, two speakers).
Subwoofer for bass, now you have 2.1. The "2" represents two front speakers and the subwoofer is ".1 ".
Add a mid-channel speaker, so the dialog always seems to come from the center of the screen (if you're sitting on one side is slightly important), and we have "3.1".
Add two more speakers near the back of the room for surround sound. We are in the "5.1" state for surround sound. (5.1 was the surround sound standard, until a few years ago, when things started to get crazy.)
Larger rooms, especially where the sofa is separated from the back wall, may require side and rear surround speakers, which brings us to "7.1".
Dolby Atmos: we put two or more speakers on the ceiling. Now we're talking about actual 3D sound, where any sound can hover at any point in space.
So, "7.2.1" system has three speakers in the front, two on the side, two in the back, and a pair on the ceiling. Plus the subwoofer, usually in the back, but can go anywhere.
