目前音響的設備種類繁多，更新換代也是日新月異，這么多的設備在使用當中難免會有一些各種各樣的故障，下面我們來講講音響系統常見的電源故障和線路故障吧。
At present, there are many kinds of professional audio equipment, and the upgrading is also changing with each passing day. So many equipment will inevitably have various faults in use. Let's talk about the common power supply faults and line faults of professional audio systems.
1音響系統電源故障

三相動力電：一般使用音響設備的場所都會申請安裝三相動力電源，比較重要的場所還會采用兩條各自獨立的三相動力電源，萬一其中一條出現故障時不于整個系統都癱瘓；甚非常重要的場所還會使用類似于電腦的“UPS”之類的備用電源，可見電源方面是多么的重要。
Three phase power supply: generally, places using professional audio equipment will apply for the installation of three-phase power supply, and more important places will also use two independent three-phase power supply, in case one of them fails, the whole system will not be paralyzed; Even very important places will use standby power supplies such as "ups" of computers, which shows how important power supply is.
音響、燈光電源分開：音響系統和燈光好要有各自的電源，否則一個是容易產生干擾，再一個工作起來也不。
Separate the power supply of sound and light: the sound system and light should have their own power supply, otherwise one is prone to interference, and the other is unsafe to work.
總電源分配：光有強勁的電源還不夠，還要注意對電源的分配；原則上調音臺及各種音源設備要有一路獨立電源；各種周邊設備要有一路獨立電源；功放及其它設備還要有少2路獨立電源。每一路獨立電源用相應的空氣開關控制，這樣我們在開關設備時就非常方便了。
Total power distribution: strong power supply alone is not enough, 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 kinds of peripheral equipment should have an independent power supply; Power amplifiers and other equipment should also 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.
2音響系統線路故障

山東音響廠家講講信號線路故障：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。
Shandong professional audio manufacturers talk about signal line failure: if a set of audio system is compared to a person, the signal connection line of the audio system is like a human blood vessel. How "blood circulation" directly affects the stability of the audio system.
功放和音箱連接線路故障：功放和音箱之間的連接大家都比較重視，都會采用質量好的、粗一點的音箱線。音箱線出現故障一般就是短路了，現在音箱都是采用6.35插頭，這樣的插頭短路的危險就會大增；音箱線一般很少出現斷路情況，那么粗的線要是斷路了一般就是人為的了，不大可能是線材本身問題。
Failure of the connecting line between the power amplifier and the speaker: everyone pays more attention to the connection between the power amplifier and the speaker, and will use a thicker speaker line with good quality. The failure of the speaker cable is usually a short circuit. Now the speakers use 6.35 plugs, so the risk of short circuit of plugs will increase greatly; Generally, the speaker line is rarely broken. If the thick line is broken, it is generally artificial, which is unlikely to be the problem of the wire itself.
Some of the common faults of professional audio systems are the faults of the equipment itself, and some are man-made faults caused by improper use. The above are the related problems of the problem. For more information, please visit the website http://www.zkvd.cn Consult.
