企業(yè)的視頻會(huì)議往往部署在多媒體會(huì)議室內(nèi)，與LED、拼接屏、音響、智能會(huì)議平板、中控等系統(tǒng)集成為一體，為參會(huì)者提供一個(gè)模擬“面對(duì)面”會(huì)議的視聽效果。將會(huì)議音頻功放離不開音響系統(tǒng)的部署，山東會(huì)議室音響系統(tǒng)的線路通常會(huì)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(tǒng)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(diào)音臺(tái)及音源播放器等電源、周邊設(shè)備電源、功放電源、舞臺(tái)電源、有源音箱電源、視頻系統(tǒng)電源等等，一個(gè)場(chǎng)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(fā)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(hào)線路故障

（2） Signal line fault

假如把一套音響系統(tǒng)比喻成一個(gè)人，那么音響系統(tǒng)的信號(hào)連接線就好像是人的血管一樣了，“血液循環(huán)”如何，直接影響到了音響系統(tǒng)的穩(wěn)定性如何，但即使知道信號(hào)線是如此的重要，有時(shí)故障還會(huì)發(fā)生，歸納起來有以下幾點(diǎn)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(hào)線本身質(zhì)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(shí)導(dǎo)致信號(hào)線損害

2. Damage to signal line during installation

有時(shí)候我們用了質(zhì)量很好的線，安裝前檢測(cè)沒有問題，但安裝后就出問題了，這可能是安裝時(shí)導(dǎo)致了信號(hào)線的損害，特別是有些長(zhǎng)距離傳輸?shù)木€材，有時(shí)候在安裝過程中穿管時(shí)太用力扯線材時(shí)，就可能導(dǎo)致線材損壞；也有可能是別的工種在施工時(shí)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(shí)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(hào)線焊接問題

3. Signal wire welding problem

在焊接信號(hào)線時(shí)一方面要注意每一個(gè)焊點(diǎn)的焊接質(zhì)量，是各種信號(hào)線與其相應(yīng)的各種接插頭之間要正確對(duì)接的，比如XLR卡儂接頭有1、2、3三個(gè)接點(diǎn)，不能搞混了，所以信號(hào)線焊接好后還要用萬用表檢測(cè)一下，看會(huì)不會(huì)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?cè)胄械陌l(fā)燒友可能會(huì)將會(huì)議、公共廣播和舞臺(tái)演出的音響系統(tǒng)混淆，本質(zhì)上它們都是音響系統(tǒng)，但其實(shí)他們都有非常明顯的側(cè)和適用場(chǎng)合。更多相關(guān)音響系統(tǒng)的事項(xiàng)就來我們網(wǎng)站http://www.r08sv.cn咨詢吧！

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.
