Several tricks for KTV audio debugging

　　If you go to entertainment venues such as bars, KTVs, etc., you can feel that all the professional equipment has been debugged. How to debug it? The following Din Tai Fung audio editor tells you how to adjust the equipment.

　　KTV debugging should be a combination of theory and practice. Without theoretical guidance and blind debugging, the effect will not be as good. KTV sound reinforcement must ensure several basic factors: sound pressure level, sound field uniformity, clarity, and reverberation. It is necessary to understand some basic electronic acoustics knowledge of equipment.

　　KTV sound reinforcement must ensure several basic factors: sound pressure level, sound field uniformity, clarity, reverberation, and to understand some basic electronic acoustics knowledge of equipment.

　　Sound pressure level: To put it simply, the power of the audio system should be sufficient, and the volume of the private room should be equipped with how much power. This is the first thing to guarantee. Generally, the best sound pressure range of speakers in KTV private rooms is between 2.5 and 2.8 meters. That is to say, it is better for you to keep the distance between the hanging position of the speakers and the sofa singing area near here. If you don’t believe me, you can test it and hold it. Move the microphone slowly from the sofa to the speaker position to see if singing is better at this distance.

　　Sound field uniformity: The installation position of the speaker is very important. According to the horizontal and vertical diffusion angle of the speaker, the hanging position of the speaker is reasonably arranged, as well as the horizontal and vertical rotation and pitch angles to ensure a uniform sound field in the listening area.

　　Clarity: Reasonable room design and layout, proper sound absorption and diffusion are a simple way to ensure sound reinforcement clarity. If the room uses a lot of glass, mirrors and parallel smooth walls, it is necessary to consider adding sound absorption and diffusion measures at appropriate locations. . The main method is repeated testing. If the room already has a lot of sound-absorbing materials and cannot be removed, you can refer to the frequency division design of the existing speakers to transform the speakers, such as increasing the number of tweeters, it is recommended to use a 2.5" tweeter to make up for the excessively absorbed tweeter. , increase the clarity of the treble; too much low frequency will also affect the clarity of the room. If you try to attenuate a lot in the tonal part, it will cause signal distortion, which is too much. There is a trick you can try: spray self-spraying paint on the woofer unit, often It needs to be sprayed several times. Let’s analyze the specific situation in detail, so that the woofer paper cone changes its characteristics and tends to the mid-frequency. Hehe, try it again. The bass is also related to the installation position of the speaker. It is also necessary to adjust the speaker position to find a better balance point a way.
