目前音响设备种类繁多，这么多设备在使用当中难免会有一些各种各样的故障，有些是设备本身的故障（硬故障），有些是使用不当造成的人为故障（软故障）。今天厂家主要讲电源故障，希望能帮到大家。
At present, there are many kinds of professional audio equipment. It is inevitable that there will be various failures in the use of so many equipment. Some are failures of the equipment itself (hard failures), and some are man-made failures (soft failures) caused by improper use. Today, Shandong professional audio manufacturer mainly talks about power failure, and hopes to help you.
音响系统总的电源配置很重要，需要注意的有以下几点：
The general power configuration of the audio system is very important. The following points should be noted:
1、叁相动力电
1. Three phase power electricity
一般使用音响设备的场所都会申请安装叁相动力电源，比较重要的场所还会采用两条各自独立的叁相动力电源，万一其中一条出现故障时不于整个系统都瘫痪；甚非常重要的场所还会使用类似于电脑的&濒诲辩耻辞;鲍笔厂&谤诲辩耻辞;之类的备用电源，可见电源方面是多么的重要。
Generally, the places where professional audio equipment is used will apply for installing three-phase power supply, and the more important places will also use two independent three-phase power supplies, in case one of them fails, the whole system will not be paralyzed; Even very important places will use backup power supplies such as the "UPS" of computers, which shows how important the power supply is.
2、音响、灯光电源分开
2. Separate audio and light power supply
音响系统和灯光好要有各自的电源，否则一个是容易产生干扰，再一个工作起来也不。
Sound system and lighting should have their own power supply, otherwise one is easy to cause interference and the other is not safe to work.
3、总电源分配
3. Total power distribution
光有强劲的电源还不够，还要注意对电源的分配：原则上调音台及各种音源设备要有一路独立电源；各种周边设备要有一路独立电源；功放及其它设备还要有少2路独立电源。每一路独立电源用相应的空气开关控制，这样我们在开关设备时就非常方便了。
It is not enough just to have a strong power supply, but also pay attention to the distribution of power supply: in principle, the mixer and various sound source equipment should have an independent power supply; All peripheral equipment shall have an independent power supply; Power amplifier and other equipment shall have at least 2 independent power supplies. Each independent power supply is controlled by the corresponding air switch, so it is very convenient for us to switch the equipment.
设备分电源故障
Equipment sub power failure
设备本身的电源故障也可以分为3部分：
The power failure of the equipment itself can also be divided into three parts:
1、设备内部本身的电路部分故障
1. Partial failure of circuit inside the equipment
这个我们一般的音响师没办法排除，需要的维修人员或设备供应商来保修。
Our ordinary sound engineers can't rule it out. Professional maintenance personnel or equipment suppliers are required to provide warranty.
２、供给设备的电源有问题
2. There is a problem with the power supply to the equipment
比如有一些直流供电的设备要使用变压器，有时候变压器会出现故障；还有就是连接设备的电源线有问题，这种情况很少发生，不过也真有好好的电源线看起来没问题就是不通电，而换一条电源线故障就排除的时候。
For example, some DC powered equipment need to use transformers, and sometimes the transformers will fail; The other thing is that there is a problem with the power cord connecting the device. This rarely happens, but there are really good power cords. It seems that there is no problem but they are not powered on. When a power cord is replaced, the problem is eliminated.
接插设备的装置有问题
There is a problem with the device of the patch device
比如与设备相连接的插座、电源时序器等有问题，这种故障的发生机率相对来说还是很高的，特别是在流动演出时要更加注意。
For example, there is a problem with the socket and power sequencer connected to the equipment. The probability of such a failure is relatively high, especially in mobile performances.
现在各行各业用电量都在增加，因此电源的电压就很难保证在一个恒定的标准范围内，这种情况下好多使用音响的场所就给音响系统配置了稳压器等电源处理设备，但在挑选设备时一定要注意稳压器的稳压功率和质量。更多相关内容就来我们网站

Now the power consumption of all walks of life is increasing, so it is difficult to ensure that the voltage of the power supply is within a constant standard range. In this case, many places where audio is used have configured the audio system with power processing equipment such as voltage stabilizer. However, when selecting equipment, pay attention to the voltage stabilizer's stabilized power and quality. More relevant content will come to our website Consult!
