The author conducted an experience on the large-scale KTV in Beijing. The best thing is the store of Qianjian (Xiangwai Shenlu Street), but the sound effect is still missing a lot of things, especially the accompaniment music and CD discs. Relatively large, perhaps because of the recording, the pursuit is too high. Many friends invited me to listen to the sound effects of the cashbox. My feeling is that they only added some professional sound reinforcement concepts to ordinary karaoke equipment. It is not difficult to achieve good karaoke effects, as long as you respect science. Designed in strict accordance with the audio specifications, the sound effect will meet your requirements, and the effect will be better than the money cabinet.
Leather is not blown, we only need to understand some acoustic knowledge and professional sound reinforcement knowledge to reveal the secret of the sound effect of the money cabinet. We know that the sound quality is determined by three factors, one is the sound field factor; the other is the sound reinforcement system factor; the third is the accompaniment music source factor, which determines the effect of karaoke. Below we discuss separately.
Karaoke sound field environment: Currently, according to the size of the room, it can be divided into small rooms, medium rooms and large rooms. Usually small rooms are 4 to 15 square meters; medium-sized rooms are 15 to 30 square meters; and more than 30 square meters are large rooms. Such classification may not be very reasonable. We should not care about this first. First of all, we must know whether the reverberation time in the room is conducive to karaoke singing. The long reverberation time is easy to cause whistling, and affect the clarity of the sound. It will take a lot of effort to sing for a short time. Usually the reverberation time is between 0.7 and 1.2ms. The easy way is to clap in the room and feel the reverberation of the sound in the room. If the resonance is moderate, it means that the reverberation time of the room is appropriate. The room and the sound insulation of the room are also very important, especially the material and structure of the wall. We found that the sound insulation of the two rooms is not good. Most of them are not caused by sound insulation. Ventilation pipes, doors and windows are between the room and the room. The important part of the sound, from the perspective of green acoustic environmental protection, the noise can be managed. When the design of the decoration is hired by the acoustic experts, some problems can be effectively solved. The overall decoration of the cashbox is relatively good.
Karaoke sound reinforcement system: This is the most complicated problem. The conventional configuration is caused by audio source equipment, karaoke amplifier, karaoke speaker, microphone and song device. Since the environment of karaoke is generally small, the singing effect is not as good as that of the lobby, and it is difficult to guarantee the effect with less system control devices. Most of the sound effects are not ideal. The more mature karaoke equipment in China should be BMB products. Many domestic brands are also copying BMB products, but the sound quality is not as good as the genuine goods. The sound system of the cashbox is a system that has been reassembled by professionals. His power amplifier is equipped with a professional Yamaha 100 effect on the karaoke machine produced by Pioneer in Japan. The middle and high notes of the speaker have also been adjusted. The choice of the microphone is also human. The sound sings are better varieties, and together they form the sound effect unique to the money cabinet. Recently, we went to the Beijing New Store (the first store) of the cashbox to experience. We felt that it was not as good as the Beijing Chaowai store. The main reason was that the effect equipment did not play out. The sound engineer adjusted for a long time and did not achieve the desired effect.
Karaoke accompaniment music: At present, large-scale KTVs are all VOD computer on-demand systems. The accompaniment music of the cashbox is genuine. They use MD, LD and VOD at the same time. All the accompaniments are stereo. This uncompressed accompaniment is good. Other KTVs are inferior. It is better to use VID than to use midi, and use Malata instead of LD (the source is too small). It is better to use VOD than LD, and use VOD as the money cabinet.
Since we know that the effect of karaoke is determined by the above three factors, can we fundamentally solve the karaoke singing effect problem? The answer is yes, yes.
After scientific analysis and comparative experiments on various brands of karaoke speakers and amplifiers, we found that an important method to solve the karaoke sound effect is the relationship between karaoke speakers and singing microphones, many karaoke sounds. The system works especially well when delivering CD audition discs. When singing karaoke, the accompaniment and vocals cannot coincide. The serious one is howling. Then we should consider the part of vocals and music when designing the speakers. The treble of the speakers in the cashbox is 4, so it is particularly easy and natural to sing. We will transform the selected karaoke speakers, add high-pitched sounds and deal with low-frequency sounds, so that the accompaniment music has the feeling of fever (Hi-Fi) music. The processing of vocals is focused on the power amplifier. We have chosen digital control. The karaoke amplifier has increased the incentive function and made the vocal processing more delicate. Microphone We use a domestic dynamic sing microphone to ensure that there is no whistling within a certain range.
The fundamental problem in solving the karaoke sound effect is to have a technical support team. The money cabinet employs many audio experts and acoustic experts as their technical support, and introduces the professional sound reinforcement peripheral equipment into the karaoke system from the concept of professional sound reinforcement. From the production link to the equipment and equipment, such as speakers, amplifiers, microphones are custom-made cabinets, work pays off, the sound effects of the money cabinet can be recognized by people is closely related to their emphasis on sound technology.
The introduction of a surround sound box, center speaker, and subwoofer makes the karaoke sound effect even better. In addition to the increased power, many large KTV and luxury private rooms have added surround speakers, center speakers and subwoofers. The microphones also use wireless microphones. This configuration makes the singing better and can also be suitable for small and medium-sized dances. .
Some units have established a number of fine KTV entertainment projects in Beijing through technological transformation, and designed products with high skill-price ratios suitable for China's national conditions. After the operation, they have been recognized by the industry, with the aim of reducing investment and waste and allowing more People enjoy the experience of high-end, healthy, safe, comfortable and happy karaoke sound effects. The main equipments are domestically produced or joint ventures and cooperative products. The common feature of these products is that the performance price ratio is particularly high. The sound effects are similar to those of "Qiancai" and "Good Ledi", but the price will be much lower than them.
For example, the design concept of the TPMPO speaker has attracted foreign advanced technology and introduced Hi-Fi into professional karaoke audio. This factory produces speakers and has a certain popularity in China. They are optimized from the speaker cabinet structure, the size of the speaker, the position of the speaker, the position of the phase inversion, the structure of the divider and the sound absorbing material in the box. Usually, the karaoke speaker is a rectangle. This speaker is designed as a pentagonal box for expanding the diffusion angle of the treble. Usually, one speaker is a woofer and one or two tweeters, and this speaker is added to four trebles. The crossover is designed according to the principle of the fever speaker and uses a three-way Hi-Fi circuit. The overall dynamic range of the audio-visual effect is wide and the resolution is very high, especially when the human voice is singing. Because the structure of the speaker is reasonable, the sound is also small at large sound pressure levels, and it can be used for a long time. The total power of the speaker reaches 250W, which can be used in rooms up to 40 square meters. Another feature of the speaker is that the volume is still good when the volume is turned on.
Finally, what should be explained is the regulation of the overall system. With good hardware, can it achieve good sound effects? The answer is "NO". Factors such as wire, connectors, speaker placement, etc. all affect the sound quality of the speaker system.
At present, many investors are optimistic about the high rate of return of high-end KTV, and they have chosen to invest in this project. They used the "钱柜" and "good music" as the original version of the cat to draw the tiger's grass, and because there is no experience, often no money to invest, the built-up business site "hardware" and "钱柜" "good music" grade and taste far apart. In addition, there is a big gap between service quality and management. There are many sequelae caused by lack of experience in all aspects of software and hardware. Naturally, there is no high rate of return like "钱柜" and "good music".
