Live demonstration of entertainment audio PK

　　Karaoke is a characteristic product of Chinese entertainment audio, which is similar to but different from professional audio, civilian audio, and recording audio. It is difficult to have an established standard. The positioning of the market, the preference of the region, including the personal understanding of the investor. Give this industry a room for a hundred flowers to bloom. There must be a reason for existence, and it is intolerant to comment on a certain style in general terms. For entertainment venues: what is needed is not the best sound, more needs are the most suitable sound. The cost of return on investment and the payback period are what Party A is most concerned about. Therefore, it is indeed not easy to make a stable and professional sound system that meets the needs of guests under limited conditions. We only have to use professional technical frameworks in many ways to understand and use good equipment more. Do your best to cater to and guide the project. Perfect the program from a professional perspective.

　　A reasonable allocation plan is the basis for good results. Understanding the performance and style of the company's various products is the first step. Cooperate with the business department to feed back Party A's information, and place orders under the technical framework as much as possible. The process may conflict with the maximization of profits pursued by sales. Among them, the severity should be submitted to the higher level to grasp before the PK. Don't shirk each other's responsibilities on the spot.

　　KTV private room entertainment audio distribution list can be roughly divided into professional and card package, of course, some people use coaxial speakers and line array speakers. Personally, I think it is very suitable to make a small-scale mass sales room with a card package. Due to the difference between the speaker material and the treble material, the low-frequency dive of the card box is easy to achieve fullness and flexibility, fine high-frequency, wide coverage, light suspending, and simple system. With the consumer market's demand for large areas, large dynamics, and loud sound pressure. Some card packs cannot meet the requirements of the venue, and more and more professional boxes are in use. You may remember that a few years ago there was a professional card holder that was also popular for a while. Professional boxes are generally horn treble and selvedge bass. The sound pressure and power are relatively large. The equipment and debugging of the system are also relatively complicated.

　　Professional private room entertainment audio systems generally include: audio source, microphone, pre-effects, power amplifier, main speakers, auxiliary speakers, and ultra-low speakers. It is recommended to test whether the power supply voltage is normal before plugging in the system at the PK site, and whether the welding machines and woodworking machines used in the renovation work of the site will affect the power supply. Whether the speakers are hung up and placed properly and safely, if there are too many PK manufacturers, there is no suitable location. Can you put it up after another demo? Location is a link that cannot be ignored.

　　If there is a subwoofer, you need to consider the position and phase. If possible, test it to see the full frequency and ultra-low delay phase. Approximately estimate the frequency characteristics of the room based on the on-site sound environment. Even the person who sings during PK and the person who scores are in that area, so they have to understand. Whether the speakers are hung horizontally or directly. The coverage angle of the horn needs to be changed, and whether the connection between the speaker and the professional power amplifier is correct must be carefully checked. There are generally two toggle switches behind the power amplifier. One is sensitivity and the other is bridge conversion. To see if it is hit in the right position. Whether the wiring between the power amplifier and the effector is correct (especially the system with auxiliary rear box) must be right and left, so that the sound field of the accompaniment music is correct. Whether the battery level of the wireless microphone is sufficient, whether the frequency of the receiver is aligned, and whether the timbre and sound pressure of the two microphones are the same. You have to be aware of it. When everything is normal, we will play a little dynamic music that we are familiar with, which is different from our usual listening experience. Is it the same as our estimated room frequency characteristics? If everything is normal, you can play a more dynamic music, slowly increase the volume, and listen for abnormal sounds or resonance. At this time, you can smoke a cigarette and take a break. Ready to fine-tune the next entertainment audio
