KTV audio PK precautions.Car stereo sales

　　Due to the small size of the KTV audio system and the simplicity of the system, the PK battle of the audio system was preceded by the KTV audio system. Everyone has the same experience and different opinions on the PK of the KTV sound system. Below I will make a simple analysis based on my own experience over the years for my colleagues' reference.

　　1. To understand the nature of the customer’s KTV venue and the requirements for the sound system. I think most of you have been to customer KTV venues before Audio PK. First of all, you need to know the customer's experience mode after KTV: generally mass sales and night scenes. If it is a mass sales type, the general requirements for audio are: beautiful appearance, high fidelity, easy, delicate and sweet singing. If it is a KTV at night, the general requirements of customers are: Hi singing combined with good bass effect. This generally requires consideration of power issues. Hi-singing is actually a regular problem that we all encounter. Generally, the woofer of KTV speakers has a foam edge, and the treble is a paper cone, so its treble is delicate, and the bass is soft and submersible. But its sense of power is not enough, and guests always feel that the bass is not heavy enough. Some boxes are equipped with active subwoofers, but they still cannot meet the requirements of the guests. If a professional box is used, a 12-inch full-range box and an 18-inch passive subwoofer are generally used. Now the ultra-low effect is there, and the music effect is quite good. But the singing effect is greatly reduced. Because the treble of the professional box is a horn and the woofer is a fabric-edge structure, the treble is harsh and the bass is hard when singing, and there is no delicate and soft feeling at all. I think people in the industry have encountered similar problems. If the customer requires the few luxurious large boxes to be combined. I suggest that you can mix professional and card boxes. Each exerts its own strengths. This greatly increases the cost. Of course, the use of high-quality imported boxes can achieve fine treble without stabbing heavy bass without mixing. But the price is not cheap. Are you ready before PK? Before PK, you didn't have any concepts, do you still use PK?

　　Two, KTV audio PK should be fully prepared. A complete KTV sound system and a complete set of auxiliary accessories are essential. Don't go to PK, you still can't install it. You will be embarrassed then. Does the boss have the patience to wait for you to install it tomorrow? I think the boss has denied you. There is another guy who forgot to bring the speaker stand during the PK. He even came up with a way to kill: Put the speaker on the sofa and PK with everyone. Is the pointing performance of the high pitch good? Can such a bass transient response be good? As a result, he killed himself in advance.

　　Three, pay attention to several matters when KTV audio PK. 1 The speakers should be placed reasonably, and the placement of the speakers directly affects the effect of the sound quality. In fact, you have to know that there is only one good place in a sound field. Most of the audio companies that PK went to early were to find a good place. 2 is the speaker power amplifier matching should be reasonable, the connection should be correct. This is also a common fault of many of our colleagues. Many audio companies in the PK from time to time the phase of the speaker is reversed, that is, the microphone is reversed. Will the sound effect be good? 3 is to have sufficient time to warm up the audio system and debugging time. Everyone should know that the effect of the sound system after warming up is much better than when it is turned on. Also, you must have good audio debugging technology to give full play to the better effect of your audio system. 4 is to understand the taste requirements of the examiner for sound effects. If it is an older examiner to test the sound, you can't use disco music to expect to give you a high score for the sound effect. Maybe an excellent old song will make him very satisfied with your acoustics. A good sound source is also very important during the audition. I believe that everyone in the industry is willing to volunteer their own audition discs. 5 In PK singing, it is necessary to quickly
