How to choose to achieve the best KTV sound effect

　　As a place for entertainment and relaxation through singing, KTV, apart from external conditions such as price and service, the quality of KTV sound effect is a factor that consumers are most concerned about. A good sound system can provide consumers with a comfortable sound environment and bring consumers a good karaoke experience. Even if the price is slightly high, consumers with entertainment purposes will feel "value for money".

　　What we must make clear is that the sound effect is described by characteristics, and cannot be simply summarized as good or bad. There is a big difference between KTV audio and stage audio, home audio, and fever audio: KTV audio in a designated area must be To gain the greater recognition of the target consumer group, it is necessary to form a consumption habit that conforms to the regional culture and a certain consumer group. KTV audio designers and investors are required to make rational decisions, and the so-called successful experience cannot be completely copied.

　　Due to regional differences and differences in the characteristics of consumer groups, the requirements for KTV sound effects are also differentiated. Some require HIGH effects, and the effects must be quite shocking; some require a beautiful combination of vocals and music. But no matter what, the design of KTV sound effects is the basis for realizing all effects.

　　The KTV sound effect design includes several aspects such as the configuration of the audio equipment, the coordination of the decoration of the private room, the selection of the furniture of the private room, the installation of the audio equipment, and the parameter setting of the audio equipment. Here we mainly discuss the configuration of KTV audio equipment.

　　There are many kinds of KTV audio equipment, and there are many configuration and combination schemes. It is actually a technical and complex project to choose the best match from many equipment. The configuration of KTV audio equipment pays attention to eight words: the singer is comfortable, the listener is comfortable, or, it is comfortable to sing and listen to. These 8-character mantras are simple to say, but it is impossible to realize them without some effort.

　　The selection of KTV private room speakers is divided into main speakers and auxiliary speakers. The main evaluation of private room speakers is that the expressiveness of the human voice should be prominent, and the sound phase should be correct (listen to see if the human voice can be sent out, some speakers will feel The vocals are behind the cabinet), and the music frequency response should be wide and dynamic enough. The choice of private room speakers should also be determined according to the consumption patterns of the target consumer group. The consumption concept of karaoke consumers in big cities is relatively mature, and the classification of entertainment venues is relatively fine. Basically, K and HI can be ignored or less considered. Compatibility depends on the market positioning of investors. Pure K mainly considers the expressiveness of vocals. The vocal expressiveness of 8" woofer speakers is better, and the musicality of 10" woofer speakers will be much better, but the vocals are slightly worse.

　　The selection of microphones in the KTV audio configuration is very important. Early engineers liked to use professional stage microphones such as SHURE. It was not until recently that they realized the professional attributes of karaoke microphones. The switch is durable and the lead is tough. This is the most basic requirement. The most important thing is that the karaoke microphone must not be so easy to feedback howling (flying marks), and the human voice must be optimized and enhanced to attenuate the unnecessary low frequency of the human voice. And super high frequency, make the middle and high frequency of human voice more prominent, the so-called easy to sound.

　　The choice of KTV amplifier. KTV power amplifiers are divided into combined karaoke power amplifiers and separate combinations of front and rear stages. According to the type of microphone effect, they are divided into traditional ECHO and DSP. It is very important to choose the matching of the power amplifier and the speaker. The impedance, sensitivity and power of the speaker will affect the selection of the power amplifier. The general principle is that the power of the speaker with high sensitivity is correspondingly smaller, and the power of the power amplifier is 2 times the power of the speaker, and the speaker with low sensitivity The power should be correspondingly larger, and the power of the amplifier should be 2.5 to 3 times the power of the speaker. This configuration is relatively stable and the KTV sound effect is of course great.
