调音台通道电平衰减开关：
Mixer channel level attenuation switch:
一些调音台器在增益旋钮前增加了一个大约20诲叠的电平衰减开关。当颁顿或其他音源从高阻端口输入时，由于高电平，可能需要按下此开关来衰减音源信号。20诲叠比较合适，但是如果有的音响师在演出的时候不小心按了这个开关，声音信号会突然增加20诲叠而不衰减。如果它跳起来，一些音响设备会当场报销，所以我们在调节每个旋钮或开关的时候一定要有明确的目的，不要盲目操作。
Some mixers add a level attenuation switch of about 20dB in front of the gain knob. When a CD or other sound source is input from the high resistance port, it may be necessary to press this switch to attenuate the sound source signal due to the high level. 20dB is more appropriate, but if some sound engineers accidentally press this switch during the performance, the sound signal will suddenly increase by 20dB without attenuation. If it jumps up, some audio equipment will be reimbursed on the spot, so we must have a clear purpose when adjusting each knob or switch, and don't operate blindly.
调音台增益调整：
Mixer gain adjustment:
一些音响工程师不知道通道增益的重要性，所以他们随意调整旋钮。有时他们会关闭增益旋钮，甚同时按下20诲叠电平衰减开关。想想此时的声音会有多低？音乐的信噪比和动态根本谈不上。如果用同样的方法调整麦克风通道，歌手也只能承认自己倒霉，即使大喊大叫，也不会发出高亢而富有穿透力的歌声。
Some sound engineers don't know the importance of channel gain, so they adjust the knob at will. Sometimes they turn off the gain knob and even press the 20dB level attenuation switch at the same time. Think about how low the sound will be at this time? The signal-to-noise ratio and dynamics of music are not at all. If the microphone channel is adjusted in the same way, the singer can only admit his bad luck. Even if he yells, he will not make a loud and penetrating song.
当然，有些音响师喜欢把增益调到很高，这对音乐有好处，但音乐难听，歌手却惨不忍睹。再大一点就好像洪水冲破堤坝一样不可控制，高亢的歌声也会变得不可控制。像断锣或爆豆一样的嘈杂，因为此时信号电平太高，信号已经严重失真，这种情况下麦克风经常会返回输入。可见增益很重要，不然会在表演过程中造成意外。
Of course, some sound engineers like to set the gain very high, which is good for music, but the music is ugly, but the singer is miserable. A little bigger is as uncontrollable as a flood breaking through a dam, and the high pitched song will become uncontrollable. It is as noisy as breaking a gong or exploding beans, because the signal level is too high and the signal has been seriously distorted. In this case, the microphone often returns to the input. It can be seen that the gain is very important, otherwise it will cause accidents during the performance.
调音台均衡组调整：
Adjustment of mixer balance group:
顾名思义，调音台器主要是用来调节音色的，而音色的调节主要靠均衡组。认为，其实很简单。无非就是高、中、低音加上几个对应的频率选择旋钮。不一定很好，但也不会出现演出事故。
As the name suggests, the mixer is mainly used to adjust the timbre, and the timbre adjustment mainly depends on the balance group. Shandong sound believes that it is actually very simple. It's nothing more than high, medium and bass plus several corresponding frequency selection knobs. Not necessarily good, but there will be no performance accidents.
然而，一些音响工程师有时会大胆地转动平衡旋钮。如果低音加入量大，会大大增加整个功放和音箱的负担，可能损坏设备，声音容易失真；如果音高太高，高音扬声器会很危险。总之，均衡旋钮应该抬高到一定程度。过度增加会导致不可预知的故障。
However, some sound engineers sometimes boldly turn the balance knob. If the bass is added in a large amount, it will greatly increase the burden of the whole power amplifier and speaker, which may damage the equipment and distort the sound easily; If the pitch is too high, the tweeter can be dangerous. In short, the balance knob should be raised to a certain extent. Excessive increases can lead to unpredictable failures.
