Want To Install A New Home Theater? Then You Should Route According To 9.1.6

- Jun 16, 2020-

Home theater has become a product combining digital technology and electroacoustic science. When Dolby Atmos and DTS X were launched, the expansion of the number of channels became easier than ever. More and more speakers will bring better and better real experience.


If the audio-visual room is renovated this year and the speakers will be purchased next year, it is found that the cloth audio line can no longer meet the number of channels of the power amplifier. This will definitely make you have ten thousand grass and mud horses running past.


In line with the principle of spending small amounts of money and doing long-term and big things, today the cinema decides to popularize how everyone should meet the development of home theaters in the next five years.


However, I will start with how to increase the number of channels in a home theater. If you just want to use 5.1, 7.1, then the layout diagram released below can also help you sort out the idea of the silk.

The above is the most traditional 5.1 channel. Everyone noticed the front and back gaps. There is obviously a difference between the connected speakers, and the sound will appear to jump.

Therefore, we need 7.1 to supplement the sound behind. After the development of the power amplifier, some people think that the sound between the side ring and the main box still has a clear sense of jumping.

So there are 9.1 channels, but before Dolby Atmos came out, 9.1 was calculated by the amplifier itself, not the original recording is 9.1.


Dolby struggled for several years while studying how to make the soundtrack more. It is found that with traditional recording methods, the amount of sound data is too large after 9.1, and the workload of the sound mixer is also terrible. And at the same time, we also need the sound from the top of the head, so we released the revolutionary object-based technology Dolby Atmos.

This technique is first used in movie theaters. In simple terms, the sound engineer does not have to worry about how many channels the replayed speakers have. He just uses Dolby's software to make the sound. The Dolby decoder during playback will automatically determine how many speakers your system has, and then allocate the sound by itself.

In the field of home theater, ordinary people can afford the panoramic sound power amplifier, which can support this standard at the highest level, if it is divided by the number of channels, it is called 7.1.4. In this system, the ground is the traditional 7.1, and this .4 refers to four sky channels in the sky.


In fact, the highest standard of Dolby Atmos for home use is more than thirty channels.

But at present, there is only one French company's product that can be supported in the world. This PC-based AV pre-amplifier is sold for 300,000 yuan. Therefore, it does not matter much to ordinary users.

However, the problem of 7.1.4 channels also exists objectively.


Regardless of the sky or the ground, the positions circled in the picture above are extremely empty.


But I believe that in the next one to two years, there will be a 7.1.6-channel or 9.1.6-channel panoramic sound amplifier. In the latest Dolby Atmos test disc, Dolby has added 9.1.6 channel system detection.

When you click to enter the 9.1.6-channel signal test of this Blu-ray disc, its placement is like this.


Well, the focus of this article is here. Recently, some people asked their audio-visual room if only 7.1.4-channel speaker cables were pre-buried, what if the channel was upgraded later?


There is of course a way to do this, which is to advance the specifications of the wiring a little bit, and now lay the wires of 9.1.6. If you upgrade later, you only need to add speakers and upgrade amplifiers to keep up with the trend of the times.

And how to reserve the wire, then please see the picture above.


It is a trivial matter to not go to the 9.1.6 home theater now, but if there is no wiring, there will be no money to spend in the future, it is a big deal.
