音響設(shè)備有很多種，我們音響師需要把每一臺(tái)音響設(shè)備都調(diào)整好。我們說的人為操作故障主要發(fā)生在演出期間，如無聲、斷音、回輸、噪音等多種。下面
山東音響廠家就來解說幾個(gè)音響系統(tǒng)設(shè)備調(diào)控問題。
There are many kinds of sound equipment. Our sound engineers need to adjust each sound equipment. The human operation failures we mentioned mainly occur during the performance, such as silence, broken sound, feedback, noise and so on. Next, Shandong professional audio manufacturers will explain several problems of audio system equipment regulation.
1、調(diào)音臺(tái)通道電平衰減開關(guān)：有的調(diào)音臺(tái)在增益旋鈕前增加一個(gè)20dB左右的電平衰減轉(zhuǎn)換開關(guān)，當(dāng)CD等音源從高阻端口輸入進(jìn)來后，由于電平較高，可能需要按下此轉(zhuǎn)換開關(guān)把音源信號(hào)衰減20dB才合適。
1. Mixer channel level attenuation switch: some mixers add a level attenuation transfer switch of about 20dB in front of the gain knob. When CD and other sound sources are input from the high resistance port, due to the high level, it may be necessary to press this transfer switch to attenuate the sound source signal by 20dB.
2、調(diào)音臺(tái)增益調(diào)整：有些音響師不知道通道增益的重要性，對(duì)此旋鈕信手亂調(diào)，有時(shí)候把增益旋鈕關(guān)掉，甚還同時(shí)按下了20dB電平衰減開關(guān)，想下這時(shí)候的聲音會(huì)有多么小？
2. Tuning console gain adjustment: some sound engineers don't know the importance of channel gain, and adjust this knob casually. Sometimes turn off the gain knob, and even press the 20dB level attenuation switch at the same time. Think how low the sound will be at this time?
3、調(diào)音臺(tái)均衡組調(diào)整：調(diào)音臺(tái)顧名思義主要是用來調(diào)整音色的，調(diào)整音色主要還是要靠均衡組。說來很簡單，無非就是高中低音再加上幾個(gè)相應(yīng)的選頻旋鈕，正常操作下雖然音色不一定就會(huì)很好，但也不會(huì)發(fā)生演出事故。
3. Adjustment of the balance group of the mixer: as the name suggests, the mixer is mainly used to adjust the timbre, and the adjustment of timbre mainly depends on the balance group. It's very simple. It's nothing more than high, low and high bass plus several corresponding frequency selection knobs. Under normal operation, although the timbre may not be very good, there will be no performance accidents.
但有些音響師對(duì)均衡旋鈕有時(shí)候大膽地轉(zhuǎn)來轉(zhuǎn)去，如果把低音加到很大，整個(gè)功放和音箱的負(fù)擔(dān)就大大增加了，可能會(huì)損壞設(shè)備，同時(shí)聲音也會(huì)很容易失真。
However, some sound engineers sometimes boldly turn the equalization knob around. If the bass is added to a large amount, the burden on the whole power amplifier and speaker will be greatly increased, which may damage the equipment, and the sound will be easily distorted.
4、調(diào)音臺(tái)AUX調(diào)整：大家AUX主要是用來發(fā)信號(hào)給效果器的，在一個(gè)調(diào)音臺(tái)里，假如我們從AUX6發(fā)送信號(hào)效果器，經(jīng)過效果器處理后若輸出了2路信號(hào)到調(diào)音臺(tái)的23-24路，那么此時(shí)23-24兩個(gè)通道中的AUX6旋鈕就不要再打開了，否則剛才經(jīng)過效果器處理后，信號(hào)就會(huì)又流回到效果器里。
4. Adjustment of mixer aux: everyone aux is mainly used to send signals to the effector. In a mixer, if we send the signal effector from aux6, after the effector processing, if we output two signals to the 23-24 channels of the mixer, then at this time, the aux6 knob in the 23-24 channels should not be opened again, otherwise after the effector processing just now, the signal will flow back to the effector.
5、調(diào)音臺(tái)聲像：聲像旋鈕大家常常把它當(dāng)作可有可無的東西，但是當(dāng)我們用總輸出的左路或者右路輸出音量時(shí)，就要注意聲像了。如果用總輸出右路輸出信號(hào)但是調(diào)音臺(tái)通道聲像都打到左邊，就會(huì)造成無聲故障了，這是需要注意的。
5. Mixer audio-visual: Audio-visual knob is often regarded as something dispensable, but when we use the left or right output volume of the total output, we should pay attention to the audio-visual. If the total output right output signal is used, but the sound and image of the mixer channel are turned to the left, it will cause silent failure, which needs attention.
6、調(diào)音臺(tái)監(jiān)聽及靜音開關(guān)：一般調(diào)音臺(tái)監(jiān)聽和靜音開關(guān)是靠近在一起的，操作的時(shí)候一定要看清楚，如果在按監(jiān)聽開關(guān)時(shí)錯(cuò)按了靜音開關(guān)，也會(huì)造成無聲故障。
6. Mixer monitor and mute switch: generally, the mixer monitor and mute switch are close together, so you must see clearly when operating. If you press the mute switch by mistake when pressing the monitor switch, it will also cause silent fault.
