KTV as a place for entertainment and relaxation through singing, in addition to the price, service and other external conditions, the sound effect is the most concerned factor for consumers. A good sound system can provide consumers with a comfortable sound environment and a perfect k-song experience. Even if the price is slightly higher, consumers with the purpose of entertainment will feel "worth the money".
What we have to make clear is that the sound effect is described by characteristics, which can't be summarized simply by good or bad use. KTV sound is very different from stage sound, household sound and fever sound: if KTV sound in a designated area wants to get the maximum recognition of the target consumer group, it needs to form a consumption habit that conforms to the regional culture and a certain consumer group, and K is needed TV sound designers and investors make rational decisions and can't completely copy the so-called successful experience.
Due to regional differences and the characteristics of consumer groups, the requirements for sound effect are also different. Some need high effect, which is quite shocking; some require the perfect combination of voice and music. However, the design of KTV sound effect is the basis of all effects.
The sound effect design of KTV includes sound equipment configuration, room decoration cooperation, room furniture selection, sound equipment installation, sound equipment parameter setting and other aspects. 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. In fact, selecting the best combination from many equipment is a very technical and complex project. KTV audio equipment configuration pays attention to eight words: the singer is comfortable, the listener is comfortable, or to say, the singer is comfortable and the listener is comfortable. These eight words are simple to say, but they can't be realized without some time.
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 expressive force of the voice should be outstanding, the sound phase should be correct (listen to see if the voice can be sent out, some speakers will feel the voice behind the box), and the music frequency should be wide and dynamic enough. The choice of private room speakers should also be determined according to the consumption mode of the target consumer group. Karaoke consumers in big cities have mature consumption concept, and the classification of entertainment places is relatively detailed. Basically, compatibility between K and hi can be ignored or less considered, and the market positioning of investors can be seen. Pure K mainly considers the expression of human voice, 8 "bass unit speakers have the best expression of human voice, 10" ”The bass unit's sound box will be much better musicality, and the voice is slightly worse.
The choice of microphones in KTV sound configuration is very important. Early engineers like to use stage professional microphones such as Shure. Until recently, they realized the professional properties of karaoke microphones. Karaoke microphones are required to be durable in terms of net head, grip wear resistance, switch durability and lead tenacity, which are the most basic requirements. The most important thing is that karaoke microphones must not be easy to call back ）In addition, it is necessary to optimize and enhance the human voice, attenuate the redundant low frequency and ultra-high frequency of the human voice, so as to make the middle and high frequency of the human voice more prominent, so-called easy voice.
KTV amplifier selection. KTV power amplifier is divided into the combined karaoke power amplifier and the combination of front and back stages. It is divided into traditional echo and DSP according to the microphone effect type. It is very important to choose the combination of power amplifier and speaker. The impedance, sensitivity and power of speaker will affect the selection of power amplifier. The general principle is that the power of speaker with high sensitivity should be matched with a little smaller, the power of power amplifier should be twice the power of speaker, the power of speaker with low sensitivity should be matched with a little larger, and the power of power amplifier should be 2.5-3 times the power of speaker, so the configuration is relatively stable.
