This shows the importance of the sound system KTV in the entire K song environment. The importance of sound effects in KTV makes it very important to position the sound in the private room. I bought a good speaker device and put it in the KTV room. It is also very particular. Only when it is placed properly, will it make a beautiful sound, and customers can experience a better quality song.
Tips:
During the placement of the speaker, even if you move a few centimeters forward or backward, the low-frequency response of the speaker will change greatly. The speaker will be placed in a room that can enhance or weaken the bass, and the balance of the tone will occur. Change, or you will hear rich bass or no bass. Moreover, when the speaker is not positioned correctly, it is not as good as the sound image positioning that should have been.
Therefore, in the KTV private room, you should find the proper placement position for the sound, so that the speaker can fully display its power and show its talents. Let's take a look at the placement of the KTV room audio, the eight rules that usually follow:
NO.1: 361 proportional method
The length of the room is divided into three equal parts, the horn is placed at one-third of the length, and the interval between the two speakers is 0.7 times the length of two-thirds of the room. The horn preferably has a slight inward projection angle, but it does not project inward, and the listening position cannot be placed against the back wall.
How is the effect of this method? Very good. This method is used for a large-scale, even-proportioned space, resulting in a balanced sound and a wide sound field.
NO.2: Three-three-one ratio method
The length of the room is divided into three equal parts, and the width is also divided into three equal parts. The horn is placed at the first aliquot of the length and the width. The horn can have a slight inward projection angle, even without inward projection, and the listening position cannot be placed against the back wall.
This method is also applied to KTVs with a large spatial ratio and uniformity, and is also applicable to sound fields with wide and deep sound fields. However, the only difference between this method and the first method is that the spacing between the two speakers is relatively narrow.
NO.3: Screw hole pendulum method
Place the horn between one-third and one-half of the length of the room, then place the two speakers as far as possible on the sides of the wall (if the room is wide, you do not need to be close to the side wall), the inward projection angle of the two speakers is greater than 45 degree. The listening position should be about 0.5m-1m after the intersection of the projection angle crossing lines.
This method is specially designed to deal with the shortcomings of high pitch, too low midrange, and insufficient bass.
NO.4: The equilateral triangle method
The first condition is that the distance from the rear wall of the horn is generally at least 1 meter and the side wall must be at least 0.5 meter.
Condition 2 is to draw the two speakers and the listening position as an equilateral triangle.
Condition three is that the inward projection angle of the two speakers is also 45 degrees or more.
Condition 4 This regular triangle can be large or small. When the room is small and the power of the rear stage is not large, the regular triangle is smaller; when the room is large and the power of the rear stage is large, the regular triangle is painted larger.
The advantage of this method is that it can reduce the excessive interference of the reflected sound of the four walls to the direct sound of the speaker, and obtain a good sense of positioning and a sound field of wide and deep. This is the most versatile, straightforward, and clearest detail.
NO.5: Long side swing
Turn the horn against the road, with the long side of the room as the horn back wall, and the rest in a regular triangle. Listening to the location should not be attached to the wall, at least 0.3 meters away.
In this method, the IF and low frequency sensations are enhanced, but the depth of the sound field is poor.
NO.6: Diamond shape
This method is only available in square spaces. Think of the square space as a diamond, and the horn on the sides of the diamond against the wall. The diamond-shaped sharp corner behind the horn and the diamond-shaped sharp corner behind the listening position are subjected to arc or cylindrical sound wave diffusion treatment, and the horn should not be too close to the side wall.
This method can solve the problem that the standing wave of the bass space in the square space is too strong. If the square space is not so swayed, it is necessary to insert the private furniture to "settlement" the standing wave.
NO.7: Wall-mounted method
Put the horn close to the back wall, no matter whether it is 50 cm or 30 cm from the back wall, you can adjust it yourself.
This method is characterized by high frequency sharpness, medium frequency and low frequency when used, which can make the intermediate frequency and low frequency full, and the whole high, medium and low frequency can be balanced. It also makes the depth of the sound field shallower and narrower. However, if we balance the harsh sounds, it is the right way to sacrifice the sound field and seek a good voice.
NO.8: Cabinet method
This method is designed for small speakers without a stand. If the horn is placed on a low cabinet, place marble or granite under the horn and place a pyramid between the horn and the stone. It is better if there is a sandbag or iron block that absorbs vibration on the top of the horn.
The characteristic of this method is that the sound will be full and strong, and the high frequency will not be harsh. At this time, listening to the sound quality is the first appeal, and the performance of the sound field is second to none.
