KTV sound engineering installation and debugging essentials.Brand bar audio

　　The installation and debugging of KTV audio engineering is relatively simple, and everyone should have mastered it. Here is just the key points. For detailed technical issues, you can refer to what I wrote before or other relevant documents. Of course, with good products, good construction and good operators, I believe that after-sales is not a big problem.

　　1. Product selection: In order to ensure the quality of the project and minimize the after-sales trouble after the completion of the KTV audio project, the most important thing is to choose good equipment. Now there are too many brands and types of audio equipment, and the performance and quality of different equipment The difference is also very large, so we should try to choose audio products that we are familiar with or recognized in the industry when doing projects. Of course, we should choose flexibly according to the cost and characteristics of different projects. In short, it is better to use the best products or our own. Think trustworthy product.

　　2. Strict construction: We must be strict in construction, from the basic wiring to the installation of equipment, we must be meticulous. In the construction, we should mainly pay attention to the wiring problem, especially those hidden wiring, we must choose good quality Wire, choose good casing when wiring, and do it in strict accordance with the process and requirements of the project. For those open lines, even if we find faults, we can check and eliminate them better, but we still have strict requirements during construction. When the hidden dangers of the project are found, they must be dealt with in time. If there is no way to deal with them, they should be recorded in the project file. In case of any problems found in the future, it is easy to refer to and find the fault.

　　3. Equipment debugging: No matter how good the equipment is, it needs to be carefully adjusted. The KTV sound engineering sound system is generally relatively simple. When debugging, just pay attention to the moderate volume without distortion, and the microphone sound should not be too strong, otherwise it will cover up the human voice. The mid and treble, try to avoid the microphone feedback and other problems, I have talked about the specific adjustment details in the previous chapters.

　　4. Equipment protection: Generally, the most fault-prone equipment in the KTV box is the microphone, followed by the speaker equipment, and then the power amplifier and other equipment. In fact, the quality of the microphone itself is not so "fragile". The reason why it is more damaged is thanks to the guests; it is generally caused by the return input of the microphone and the failure caused by excessive overloading; the power amplifier is generally overloaded or caused by humans. Fault. Knowing which equipment is easily damaged, we can take targeted preventive measures: for example, we can choose microphones with good quality and good impact resistance, and we can also add anti-slip and shock-proof rings to the microphones, and add them when singing. Microphone sponge cover, etc. As for speakers, first of all, we need to select suitable speakers according to the area and function of the box, and then make the sound pressure level of the box reach a high level, and then adjust the volume to avoid feedback as much as possible; power amplifier In terms of configuration, it is necessary to leave room for power for the power amplifier. Now most entertainment venues lock the power amplifier in the box inside the cabinet. Of course, this can try to avoid human damage to the power amplifier caused by guests, but we must also pay attention to the power amplifier. The working environment should be as ventilated as possible.
