In addition to its own quality, the effect of sound quality is not the same in different positions, so what are the places to pay attention to? Next, let Shijiazhuang professional audio manufacturers to introduce it to you.

Placement of mid-channel speaker

The front center speaker is usually placed as close as possible to the center of the image screen. The center channel speaker has the greatest impact on the sound quality of the movie dialogue. In order to ensure that the dialogue is accurately positioned in the center of the screen and the sound is clear, a separate speaker designed specifically for the center channel should be used instead of ordinary bookshelf speakers or TV speakers.

Most of the central channel speaker horizontal horizontal cabinet, the best placement is the top of the TV (if the use of front projection display screen, placed behind the screen), that should be as close to the screen. If due to room space constraints, you can use a more economical placement program, that is, no center speaker. However, at this time, the working mode of the AV amplifier should be placed in the "phantom" center channel mode, so that the information of the center channel is evenly released from the left and right speakers, and its sound image is just in the center of the screen, which is suitable for small listening rooms. Of course, it's better to have a single center speaker.

Left and right channel main speaker placement

The placement of these two speakers has a certain relationship with the position of the mid-channel speaker. In order to ensure the stability of the left and right movement of the sound image, they should be placed on both sides of the center channel speaker, and the three speakers should be kept at an equal distance from the position of the best listener in front of the screen. Generally speaking, the positioning of the center speaker should be a distance back from the left and right speakers until the two sound fields can be completely combined to create a truly unified sound image positioning. The distance of the retreat is related to the size of the space, the listening position and the speaker used, and can be determined by experiment. In addition, the vertical height of the left and right channel speakers should be 0.3m higher or lower than the axis of the middle/tweeter speaker (preferably slightly lower), otherwise the height difference of the left, middle and right speakers is too large, and the front sound image will be given the feeling of sound image jumping when it shifts horizontally. Usually, the floor-standing speaker can meet the above requirements. If the bookshelf speakers are used as the left and right speakers, they should be fixed on the speaker bracket to make it highly consistent with the above requirements. The distance between the left and right channel speakers from the screen is related to the size of the screen. If you use a large and medium-sized color TV in a small room, the left and right channel speakers can be close to both sides of the screen. If the screen is small, you can make them a little farther from the screen to get a wider stereo field. However, do not be too far away from the screen, so as not to give people a false feeling due to the sound-image position being too far away from the screen. From this point, there is a "congenital" deficiency-the environment is too small.

To sum up, the sound directivity of the speakers of the left, middle and right channels is more important than the diffusion, that is, the radiation angle range of the three channels should be based on the best listening position. In this way, the influence of reflected sound from the floor, walls and roof can be reduced, and the clarity of sound image positioning can be appropriately ensured.
