目前音響設備種類(lèi)繁多，這么多設備在使用當中難免會(huì )有一些各種各樣的故障，有些是設備本身的故障（硬故障），有些是使用不當造成的人為故障（軟故障）。今天廠(chǎng)家主要講電源故障，希望能幫到大家。
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.
音響系統總的電源配置很重要，需要注意的有以下幾點(diǎn)：
The general power configuration of the audio system is very important. The following points should be noted:
1、三相動(dòng)力電
1. Three phase power electricity
一般使用音響設備的場(chǎng)所都會(huì )申請安裝三相動(dòng)力電源，比較重要的場(chǎng)所還會(huì )采用兩條各自獨立的三相動(dòng)力電源，萬(wàn)一其中一條出現故障時(shí)不于整個(gè)系統都癱瘓；甚非常重要的場(chǎng)所還會(huì )使用類(lèi)似于電腦的“UPS”之類(lèi)的備用電源，可見(jiàn)電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、音響、燈光電源分開(kāi)
2. Separate audio and light power supply
音響系統和燈光好要有各自的電源，否則一個(gè)是容易產(chǎn)生干擾，再一個(gè)工作起來(lái)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、總電源分配
3. Total power distribution
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(kāi)關(guān)控制，這樣我們在開(kāi)關(guān)設備時(shí)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.
設備分電源故障
Equipment sub power failure
設備本身的電源故障也可以分為3部分：
The power failure of the equipment itself can also be divided into three parts:
1、設備內部本身的電路部分故障
1. Partial failure of circuit inside the equipment
這個(gè)我們一般的音響師沒(méi)辦法排除，需要的維修人員或設備供應商來(lái)保修。
Our ordinary sound engineers can't rule it out. Professional maintenance personnel or equipment suppliers are required to provide warranty.
２、供給設備的電源有問(wèn)題
2. There is a problem with the power supply to the equipment
比如有一些直流供電的設備要使用變壓器，有時(shí)候變壓器會(huì )出現故障；還有就是連接設備的電源線(xiàn)有問(wèn)題，這種情況很少發(fā)生，不過(guò)也真有好好的電源線(xiàn)看起來(lái)沒(méi)問(wèn)題就是不通電，而換一條電源線(xiàn)故障就排除的時(shí)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.
接插設備的裝置有問(wèn)題
There is a problem with the device of the patch device
比如與設備相連接的插座、電源時(shí)序器等有問(wèn)題，這種故障的發(fā)生機率相對來(lái)說(shuō)還是很高的，特別是在流動(dòng)演出時(shí)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.
現在各行各業(yè)用電量都在增加，因此電源的電壓就很難保證在一個(gè)恒定的標準范圍內，這種情況下好多使用音響的場(chǎng)所就給音響系統配置了穩壓器等電源處理設備，但在挑選設備時(shí)一定要注意穩壓器的穩壓功率和質(zhì)量。更多相關(guān)內容就來(lái)我們網(wǎng)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 http://m.djfrj.net.cn Consult!
