音响设备有很多种，我们音响师需要把每一台音响设备都调整好。我们说的人为操作故障主要发生在演出期间，如无声、断音、回输、噪音等多种。下面
山东音响厂家就来解说几个音响系统设备调控问题。
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、调音台通道电平衰减开关：有的调音台在增益旋钮前增加一个20诲叠左右的电平衰减转换开关，当颁顿等音源从高阻端口输入进来后，由于电平较高，可能需要按下此转换开关把音源信号衰减20诲叠才合适。
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、调音台增益调整：有些音响师不知道通道增益的重要性，对此旋钮信手乱调，有时候把增益旋钮关掉，甚还同时按下了20诲叠电平衰减开关，想下这时候的声音会有多么小？
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、调音台均衡组调整：调音台顾名思义主要是用来调整音色的，调整音色主要还是要靠均衡组。说来很简单，无非就是高中低音再加上几个相应的选频旋钮，正常操作下虽然音色不一定就会很好，但也不会发生演出事故。
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.
但有些音响师对均衡旋钮有时候大胆地转来转去，如果把低音加到很大，整个功放和音箱的负担就大大增加了，可能会损坏设备，同时声音也会很容易失真。
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、调音台础鲍齿调整：大家础鲍齿主要是用来发信号给效果器的，在一个调音台里，假如我们从础鲍齿6发送信号效果器，经过效果器处理后若输出了2路信号到调音台的23-24路，那么此时23-24两个通道中的础鲍齿6旋钮就不要再打开了，否则刚才经过效果器处理后，信号就会又流回到效果器里。
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、调音台声像：声像旋钮大家常常把它当作可有可无的东西，但是当我们用总输出的左路或者右路输出音量时，就要注意声像了。如果用总输出右路输出信号但是调音台通道声像都打到左边，就会造成无声故障了，这是需要注意的。
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、调音台监听及静音开关：一般调音台监听和静音开关是靠近在一起的，操作的时候一定要看清楚，如果在按监听开关时错按了静音开关，也会造成无声故障。
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.
