使用成都夜总会音箱设备场所的电源设置是很重要的，一般都会申请安装三相动力电源，这样如果其中一个出现 故障时不至于整个系 统都瘫痪。音响系统和灯光最好要有各自的电源，否则容易产生干扰。如果可以的话， 音响系统中的各个设备最好设置独立电源 ，用相应的空气开关控制，这样开关设备会更加方便。
成都夜总会的音响比较常见的就是变压器和连接设备的电源出现问题，可以更换一个来排除故障，还有就是设备相连接的 插座、电源时序器等 有问题，特别是在流动演出时发生机率比较高。当然，排除以上情况，如果是设备内部 本身的电路部分故障，只有请专业的维修 人员或设备供应商来保修。
Generally speaking, the failure probability of the Chengdu night club sound box system is relatively small, but we still need to understand, so that when the sound box failure, we can do a simple process. There are mainly three kinds of common faults in Chengdu nightclub speakers. One, the sound box is silent There are four kinds of situations in Chengdu nightclub speakers: silence of speaker wiring, abnormal frequency dividers, breakup or burn of voice coil, and speaker wire break. The fault of the box wiring will cause no sound fault, which is because the speaker unit has no excitation voltage, and the frequency divider may have a silent welding of the lead joint, the frequency divider capacitance short circuit, and so on. Using the multimeter RX1 gear to measure the loudspeaker lead wire welding piece, if the resistance value is infinity, the lacquer can be scraped open at the two ends of the small knife, exposing the copper wire and remeasuring, if the throw is different, it is explained that the throw is different. The inner broken line of the sound circle; Due to the frequent vibration of loudspeaker, the lead wire is easily broken, and the material selection and length of the lead wire are all very important. If we use the multimeter RX1 file to measure the speaker lead, if the resistance is close to 0 ohms and there is no "click", it indicates that the voice coil is burned. Before replacing the sound circle, we should first remove the magnetic gap in the magnetic gap, and then carefully put the new ring into the magnetic gap, the positive ring, the edge test and the top and down position of the fixed ring with the strong glue. After the best position, the gap between the sound circle and the paper basin is filled to about half, sealing the dust cover, and placing the paper disc up, then placing it normally after a day. Two. Sometimes there is no sound in a sound box. There are usually three kinds of interruptions in Chengdu nightclub speakers: the poor contact of speaker leads, loosening of core guides and abnormal frequency dividers. Generally speaking, the problem of the sound coil lead material or the welding is not welded well. When the vibration of the paper basin is frequent, the failure is not sound; when the core column of the loudspeaker is loosened, the magnetic plate will be sucked to one side, and the ring is squeezed to obstruct the normal sound. If it is not moved, it can be pressed by the core column, which should be disassembled and rebonded to restore use. When there is a problem in the frequency divider, the signal of the corresponding frequency band is blocked, and the frequency band loudspeaker has a small volume failure. It is important to check whether the shunt capacitor is short circuited in parallel with the loudspeaker, and whether the interlayer inductor coil is parallel to the tweeter and whether it is interlayer short circuit. Three. Abnormal sound of sound box There are four cases of abnormal sound in Chengdu nightclub. There are litter, voice coil, core, broken basin and bad box. If there are impurities in the magnetic gap, the voice coil will rub with the debris and cause the abnormal sound. The poor sealing capacity of the box will affect the effect of playing and produce cracking. The above is the Chengdu night club reservation network for everyone to share the "Chengdu night club sound box malfunction of what reasons" content, I believe you have a certain understanding of the reasons for the failure of the sound box, the next time you meet these cases, we believe that you can check and solve the fault. Four. The total power failure of the system: It is very important to use the power setting of the KTV sound box equipment. In general, it will apply for the installation of three phase power supply, so that if one of them fails, the whole system is not paralyzed. Sound system and lighting should have their own power supply, otherwise it will cause interference. If it is possible, each device in the sound system should be set up independent power supply and controlled by the corresponding air switch, so that the switchgear will be more convenient. Five. Fault of equipment power supply More common is the power supply problems of transformer and connection equipment, can be replaced to remove the fault, and the equipment connected to the socket, power timing device, and other problems, especially in the flow performance is relatively high. Of course, if the above conditions are excluded, only the professional maintenance personnel or equipment suppliers will be required to guarantee the parts of the circuit itself. Six. Failure of power supply voltage regulator and plug - in equipment If the sound system is equipped with a voltage regulator and other power processing equipment, if the quality of the pressurizer is not good, the voltage of the voltage regulator can not reach the standard, so it is easy to fail. Seven. Circuit fault of sound system First, the quality of the connection line is better, and try to buy reliable power connection lines, and save unnecessary trouble. Second, the signal connection line should not be too hard to tear the wire when installing, in order to prevent damage to the wire. Of course, it does not rule out the problems caused by other reasons. The best way is to put several spare lines as much as possible when the line is placed. In addition, when welding signal line, ensure the correct butt between various signal lines and their corresponding plugs. Pay attention to the welding quality of each solder joint. After the signal line is welded well, it will be detected by the multimeter, and the short circuit or circuit breakage will be seen.
