Multi-channel audio system with home audio layout

With the increasing popularity of home theaters, 5. 1 channel and 7. 1 channel speakers have attracted more and more attention. But having good acoustics is not necessarily a good thing. Compared with before, the placement of 5. 1 channel speakers is much more complicated.

■ Placement of subwoofer

Because people's ears are not sensitive to the directivity of bass, they can be placed in the corner. But at this time, we must pay attention to two points:

First, the subwoofer must not be placed on objects that are easy to resonate. Once so, when the subwoofer works, the object vibrates with it, which has a great influence on the sound quality;

Second, the back of the subwoofer must not be tightly attached to the wall. This is because many subwoofers are designed in reverse. But if there is no certain distance behind the inverted hole, the bass can't be played. So, at least there should be some distance from the wall.

■ Front speakers

It is best to form an angle of 45 -60 degrees with the ear, in which the distance between the left and right speakers is determined by the position of the listener, that is, the distance between the listener and the display. Generally speaking, the front speakers can be placed parallel to the listener or like a 2.0 system, but no matter how they are placed, the height should be as high as possible.

■ Center speaker

There is only one principle for the center speaker-the position must be straight ahead, that is, on the middle vertical line of the left and right speakers. Although the distance between front and back doesn't matter, it should be as moderate as possible.

■ Surround speakers

It should be placed face to face with the front speaker or at a 60-degree angle with the human ear, and it is best to hang it at the back and 60 cm -90 cm above the head.

In a word, the well-located 5. 1 system should be clearly located and there should be no faults. Just like a bullet flying through the sky, it is necessary to have a complete sense of position change. If you don't feel this way or feel unclear, you need to adjust the position of your speaker. And the audio conversation should start from the middle, and feel that the speaker is in front of you. In low frequency, 5. 1 system pays attention to vibration, so it should have a good contrast with dynamic scenes. 5. 1 The higher the sound quality of the system, the more powerful and imposing the bass should be. For the 7. 1 speaker, it is more improved on the basis of 5. 1 channel, that is, two surround speakers are added to make the number reach four, namely left front, right front, left rear and right rear surround. Therefore, its placement is also a change based on the 5. 1 channel speaker.

For subwoofers and front and center speakers, the 7. 1 channel system is almost the same as the 5. 1 channel system.

The principle of placing the four surround speakers remains unchanged, that is, the surround speakers should form an angle of 60 degrees with the human ear, and it is best to sit 60-90cm above the head.

The change is that the surround speakers are placed face to face on your left front, left rear, right front and right rear sides, that is, all four speakers are facing you. In addition, make sure that the two speakers on the left and the two speakers on the right are in the same line.

Also, the left front and right front surround speakers should be on a straight line perpendicular to you and the computer screen, and should be on the same plane as the latter pair of surround speakers, and hung on the walls (or brackets) on both sides respectively.
