With the progress and development of the times and the development of the entertainment industry, young people's pursuit of spirituality is also higher. People who like K songs now have a sense of dependence on KTV, but KTV is not their own. It is not always possible to sing, and when you are on holiday, you need to wait in line, so in the future, install KTV in your home. It will also become a trend. Next, teach you how to build your own family KTV system.
Sound insulation and sound absorption in the room
The effect of K songs must be guaranteed, first of all, to build the sound absorption of the room. Acoustic treatment of the room, focusing on the side walls and ceiling. In principle, the processing and diffusion of indoor sound waves should be more than absorption, the purpose is to reduce the resonance intensity, and to prevent excessive use of sound absorbing materials, so as to prevent the reverberation time of the room from being too short and the sound to dry out. The side wall can evenly set some sound absorption and diffusion materials. For example, a thick wool blanket is an excellent full-frequency sound absorbing object, and the thin carpet and the tapestry only absorb the medium and high frequency. In the sound absorbing process, the lower half of the wall is more important than the upper half, and can be treated with a resonant sound absorbing structure such as a perforated plate or a thin plate. The floor can be covered with thin carpets, curtains, tapestries, etc., which mainly absorbs medium and high frequencies, and has little effect on low frequency sound absorption. Too much use will cause reverberation of medium and high frequency sounds in the room. The short time makes the sound lack color and not bright enough.
Microphone selection
The choice of microphone, if it is convenient to use, you can use wireless microphone, the advantage is that there is no audio cable, and the noise will not be guided by the loose use of the audio cable interface for a long time. But in the case of the same microphone sound quality comparison, the price of wireless microphones is much more expensive than wired microphones. The quality of the sound head determines the key to the quality of the wireless microphone. The sound head has two types of moving coil type and capacitive type. The moving coil type is a coil supported on the vibrating membrane, and converts sound energy into an electric energy signal between high-density magnetic fields. This voice head has a certain limit on the voice coil characteristics. But basically the structure is simple and the price is cheap, which is the most popular one on the market. The condenser microphone is a combination of electronic and structural high-level microphones. Its pronunciation is to use the ultra-thin gold-plated diaphragm to directly convert the sound into electric energy signals by using the change of the inter-electrode capacitance. The main feature of high-quality condenser microphones is the ability to display extremely clear original sound quality. The high and low frequency response is very wide and flat, the sensitivity is very high, the directivity and dynamic range are large, the distortion rate is small, the volume is light and fall, and the touch noise is low. Widely used in professional equipment such as recording studios, professional stage, test equipment. As a family KTV system, you should choose a dynamic microphone, because the sensitivity of the condenser microphone is high, and the sound of the sound is very easy to scream, which is easy to burn out the tweeter.
Matching of speakers and amplifiers
We all have the feeling that the volume is small, the sound is weak, the thinness, the dynamic can't come out, the dullness, the low frequency is obviously lacking, the fullness is poor, and the sound seems to shrink in the inside. When the volume is right, the sound is natural, clear, round, soft, full, powerful, and dynamic. However, when the volume is too large, the sound is not soft, rough, and has a feeling of being rooted. The rated output impedance of the amplifier should be consistent with the rated impedance of the speaker. In this way, the power amplifier is in a better design load line state, in order to give a large undistorted power, otherwise the power amplifier may be overloaded. In order to be able to withstand the impact of the signal without damage or distortion. It is recommended that the power reserve be large enough. How much margin should be left for the average sound pressure level of the system and the larger sound pressure level, which should be determined according to the K song environment. This redundancy is at least 10 dB. For modern pop music, music such as Judy, it is necessary to leave a redundancy of about 20 dB, which makes the sound system work safely and stably.
Selection of the song system
The most important thing to buy a karaoke machine is stability. No matter how good the crash is, it will definitely not work. When you play well, it suddenly crashes, even if you are happy, the mood is also destroyed. Secondly, the song library, the song library includes Quality and update speed; then the smoothness of the machine operation, the one card and one card, it will not work if you don’t respond for a long time; the other is the aesthetics and clarity of the interface, it is best to have wireless songs. WeChat songs and other features.
Effect selection
The effect is also an important device in the KTV system. Whether it is a professional singer or an amateur singer, it also needs the modification of the effect. The karaoke singer becomes full and wide through the sound after the effect, which is the most commonly used reverb effect. If singing does not add reverberation, singing will be particularly difficult, and the sound will be very thin, very dry, not round.
Display system selection
The display system needs to be determined according to the size of the area of ​​the KTV room in the home. Generally, the LCD TV is more economical, and the high-grade can use commercial display. If it is a villa, if the area is relatively large, you can use the short-focus projection directly. The machine plus the frame curtain is displayed to compare the atmospheric grades. For the interface, you can choose to have the mainstream interface of VGA and HDMI. The resolution supports 1080P to fully satisfy the display of KTV system.
Basically consider the above points, the family KTV system can be, of course, there are budgets to install some lights to do some embellishments, including sofas and other furnishings can refer to KTV chain stores. In this case, there is even more feeling of KTV rooms.
