企業的視頻會議往往部署在多媒體會議室內，與LED、拼接屏、音響、智能會議平板、中控等系統集成為一體，為參會者提供一個模擬“面對面”會議的視聽效果。將會議音頻功放離不開音響系統的部署，
山東會議室音響系統的線路通常會有哪些故障？該如何處理？
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）電源線路故障
（1） Power line fault
一套音響系統里使用電源的地方很多，都需要有各種各樣的電源線來連接，比如：調音臺及音源播放器等電源、周邊設備電源、功放電源、舞臺電源、有源音箱電源、視頻系統電源等等，一個場所需要電源的部分很多，因此電源連接線要可靠，盡量避免發生故障。
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）信號線路故障
（2） Signal line fault
假如把一套音響系統比喻成一個人，那么音響系統的信號連接線就好像是人的血管一樣了，“血液循環”如何，直接影響到了音響系統的穩定性如何，但即使知道信號線是如此的重要，有時故障還會發生，歸納起來有以下幾點故障：
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、信號線本身質量問題
1. The signal line itself has quality problems
這種故障是讓人上火的，出了這種問題我們一邊只能無辜的罵罵那些奸商，另一邊還要挖空心思去重新放線，郁悶。
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、安裝時導致信號線損害
2. Damage to signal line during installation
有時候我們用了質量很好的線，安裝前檢測沒有問題，但安裝后就出問題了，這可能是安裝時導致了信號線的損害，特別是有些長距離傳輸的線材，有時候在安裝過程中穿管時太用力扯線材時，就可能導致線材損壞；也有可能是別的工種在施工時不小心損壞；還大有可能是線材被我們可愛的米老鼠練磨牙功給咬斷了，反正故障原因種種，因此放線時盡量要多放幾條備用線。
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、信號線焊接問題
3. Signal wire welding problem
在焊接信號線時一方面要注意每一個焊點的焊接質量，是各種信號線與其相應的各種接插頭之間要正確對接的，比如XLR卡儂接頭有1、2、3三個接點，不能搞混了，所以信號線焊接好后還要用萬用表檢測一下，看會不會短路或斷路。
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，不少剛入行的發燒友可能會將會議、公共廣播和舞臺演出的音響系統混淆，本質上它們都是音響系統，但其實他們都有非常明顯的側和適用場合。更多相關音響系統的事項就來我們網站

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.
