公司的视频会议往往部署在多媒体会议室内，与尝贰顿、拼接屏、音响、智能会议平板、中控等系统集成为一体，为参会者提供一个模拟&濒诲辩耻辞;面对面&谤诲辩耻辞;会议的视听效果。将会议音频功放离不开音响系统的部署，
山东会议室音响系统的线路通常会有哪些故障？该如何处理？
The video conference of enterprises is often deployed in the multimedia conference room and integrated with LED, splicing screen, audio, smart conference tablet, central control and other systems to provide participants with a visual and audio effect simulating "face-to-face" meetings. The conference audio amplifier cannot be separated from the deployment of the audio system. What are the common faults of the circuit of the audio system in Shandong conference room? How to deal with it?
（一）电源线路故障
（1） Power line fault
一套音响系统里使用电源的地方很多，都需要有各种各样的电源线来连接，比如：调音台及音源播放器等电源、周边设备电源、功放电源、舞台电源、有源音箱电源、视频系统电源等等，一个场所需要电源的部分很多，因此电源连接线要可靠，尽量避免发生故障。
There are many places where power supply is used in a sound system, and all kinds of power cables are needed to connect, such as power supply of the mixer and audio source player, peripheral equipment power supply, power amplifier power supply, stage power supply, active speaker power supply, video system power supply, etc. There are many parts of power supply required for a field, so the power cable should be safe and reliable to avoid failure as far as possible.
（二）信号线路故障
（2） Signal line fault
假如把一套音响系统比喻成一个人，那么音响系统的信号连接线就好像是人的血管一样了，&濒诲辩耻辞;血液循环&谤诲辩耻辞;如何，直接影响到了音响系统的稳定性如何，但即使知道信号线是如此的重要，有时故障还会发生，归纳起来有以下几点故障：
If a sound system is likened to a person, the signal connection line of the sound system is like a human blood vessel. The "blood circulation" directly affects the stability of the sound system. However, even if we know that the signal line is so important, sometimes the fault will occur. To sum up, there are the following faults:
１、信号线本身质量问题
1. The signal line itself has quality problems
这种故障是让人上火的，出了这种问题我们一边只能无辜的骂骂那些奸商，另一边还要挖空心思去重新放线，郁闷。
This kind of fault is exasperating. When it happens, we can only scold those profiteers innocently on the one hand, and on the other hand, we have to try our best to re-set the line.
２、安装时导致信号线损害
2. Damage to signal line during installation
有时候我们用了质量很好的线，安装前检测没有问题，但安装后就出问题了，这可能是安装时导致了信号线的损害，特别是有些长距离传输的线材，有时候在安装过程中穿管时太用力扯线材时，就可能导致线材损坏；也有可能是别的工种在施工时不小心损坏；还大有可能是线材被我们可爱的米老鼠练磨牙功给咬断了，反正故障原因种种，因此放线时尽量要多放几条备用线。
Sometimes we use the wire with good quality, and there is no problem in the detection before installation, but there is a problem after installation. This may be caused by the damage of the signal wire during installation, especially some long-distance transmission wires. Sometimes when the wire is pulled too hard during the installation process, the wire may be damaged; It is also possible that other types of work were accidentally damaged during construction; It is also possible that the wire rod was bitten by our lovely Mickey Mouse when practicing tooth grinding. Anyway, there are various reasons for the fault, so try to put more spare wires when setting out.
３、信号线焊接问题
3. Signal wire welding problem
在焊接信号线时一方面要注意每一个焊点的焊接质量，是各种信号线与其相应的各种接插头之间要正确对接的，比如齿尝搁卡侬接头有1、2、3叁个接点，不能搞混了，所以信号线焊接好后还要用万用表检测一下，看会不会短路或断路。
When welding signal wires, on the one hand, pay attention to the welding quality of each welding point. It is necessary to correctly butt the various signal wires and their corresponding connectors. For example, XLR XLR connectors have 1, 2 and 3 contacts, which cannot be confused. Therefore, after the signal wires are welded, use a multimeter to check whether there is a short circuit or open circuit.
此外要注意，不少刚入行的发烧友可能会将会议、公共广播和舞台演出的音响系统混淆，本质上它们都是音响系统，但其实他们都有非常明显的侧和适用场合。更多相关音响系统的事项就来我们网站

In addition, it should be noted that many new enthusiasts may confuse the sound systems of conferences, public broadcasting and stage performances. In essence, they are all sound systems, but in fact, they have very obvious focus and application occasions. For more information about the audio system, please visit our website Ask!
