一、 查看是否是音響線(xiàn)纜連接出現故障引起的雜音
1、 Check whether the noise is caused by the failure of the audio cable connection
檢查一遍所有的接線(xiàn)是否有松動(dòng)，或者虛焊，要排查這一步以確保以后能正確判斷故障原因。
Check whether all wiring is loose or faulty. First, check this step to ensure that the cause of the fault can be correctly determined in the future.
二、 查看是否是會(huì )議音箱的問(wèn)題引起的雜音
2、 Check whether the noise is caused by the problem of the conference speaker
1、 判斷是那只喇叭單元有壞了的方法
1. How to judge which horn unit is broken
找到是否是喇叭單元壞了，很簡(jiǎn)單，只需要在功放機的前面板上進(jìn)行調節，就可以找到是哪只喇叭單元有問(wèn)題了。，把左右平衡打到一邊，了解是哪只音箱有問(wèn)題，而后，再把高音關(guān)死，看看是否低音有問(wèn)題，如無(wú)問(wèn)題，則開(kāi)啟低音，把高音關(guān)死，聽(tīng)聽(tīng)高音是否有問(wèn)題。另一只音箱采用同樣的方法試試。
It is easy to find out whether the speaker unit is broken. Just adjust the front panel of the amplifier to find out which speaker unit is faulty. First, turn the left and right balance to one side to find out which speaker has a problem, then turn off the treble to see if there is a problem with the bass. If there is no problem, turn on the bass, turn off the treble, and listen to whether there is a problem with the treble. Try the same method for the other speaker.
2、 判斷是不是會(huì )議音箱分頻器出現問(wèn)題
2. Determine whether there is a problem with the frequency divider of the conference speaker
要判斷分頻器是否有問(wèn)題很簡(jiǎn)單，我們確定了喇叭單元，如果沒(méi)有發(fā)現，或者發(fā)現喇叭單元有問(wèn)題，但是已經(jīng)換了好的單元，仍然有雜音，那就換個(gè)好的分頻器試下就可以了。
To determine whether there is a problem with the frequency divider, we first determine the speaker unit. If there is no problem with the speaker unit, or if there is a problem with the speaker unit, but the unit has been replaced and there is still noise, then we can replace it with a good frequency divider and try it.
三、 查看是否是會(huì )議功放老化所造成的雜音
3、 Check whether the noise is caused by the aging of conference power amplifier
查看功放機是否老化了，簡(jiǎn)單的辦法是，旋轉音樂(lè )、話(huà)筒的大旋鈕看是否會(huì )加強雜音的出現，或者是一會(huì )有聲音，一會(huì )又沒(méi)有聲音。判定是功放機的問(wèn)題，那就只能換功放了，或返回廠(chǎng)里維修。
The simple way to check whether the amplifier is aging is to rotate the big knob of the music and microphone to see if it will enhance the appearance of noise, or if there is sound at one time and no sound at the other. If the problem is judged to be the power amplifier, the power amplifier can only be replaced or returned to the factory for maintenance.
四、 檢查是不是音源本身有問(wèn)題
4、 Check if there is a problem with the audio source itself
音樂(lè )或話(huà)筒本身有問(wèn)題引起雜音也非常常見(jiàn)，如是音樂(lè )本身可以用手機播放一下就可以判斷，如果是就要重新下載無(wú)損音樂(lè );如果是話(huà)筒可以用別的話(huà)筒測試就可以判斷出來(lái)。
It is also very common for music or microphone itself to cause noise. For example, music itself can be judged by playing it on a mobile phone. If it is, it is necessary to download lossless music again; If the microphone can be tested with other microphones, it can be determined.
