The sound equipment system must be set reasonably, so that the signal between various equipment will be more stable. Do you know how to set the input sensitivity of professional sound equipment? How much do you know about this? Next, we will give you a detailed summary, hoping to help you.
音响设备
Professional audio equipment
音响设备系统的信噪比(厂狈搁)较差，通常会导致背景噪声较高，使听者厌烦，影响声音的清晰度。在有效音频信号接近背景噪声的系统中，通常有太多的开销余量。另一方面，低裕度的系统，即系统噪声很低，信号接近失真，可能会导致系统过载，导致声音失真，甚烧坏喇叭。如果有几个音频设备剪辑在同一个级别(声音开始失真)或有类似的动态范围，那么这样的音频系统可以称为&濒诲辩耻辞;即插即用&谤诲辩耻辞;系统，但这种情况很罕见。
The signal-to-noise ratio (SNR) of professional audio equipment system is poor, which usually leads to high background noise, annoys the listener and affects the definition of sound. In a system where the effective audio signal is close to the background noise, there is usually too much overhead margin. On the other hand, the system with low margin, that is, the system noise is very low and the signal is close to distortion, which may lead to system overload, sound distortion and even burn out the horn. If several audio device clips are at the same level (the sound begins to distort) or have a similar dynamic range, such an audio system can be called a "plug and play" system, but this is rare.
还有一个问题。刚入行的调谐器往往误以为输入灵敏度控制器是功放上的音量旋钮。为了从这个音响系统获得更高的输出电平，通常会将其调到大值，但结果是噪音增加。因此，输入灵敏度应该设置得足够高，以确保功率放大器的输出。
One more question. New tuners often mistakenly think that the input sensitivity controller is the volume knob on the power amplifier. In order to obtain a higher output level from this sound system, it is usually adjusted to a large value, but the result is increased noise. Therefore, the input sensitivity should be set high enough to ensure the output of the power amplifier.
音响设备的设置方法基于功率放大器的输入灵敏度指示器。当指示器开始显示削波时，超过该点的任何增加都只会增加噪音。如果功率放大器控制旋钮不加区别地置于大值，调音师需要衰减混音器或信号链中其他音频设备中的信号，因此此操作会缩小输出电平和背景噪声之间的差距。因此，使用功率放大器旋钮来补偿混频器的低电平信号只会增加噪声问题。
The setting method of professional audio equipment is based on the input sensitivity indicator of power amplifier. When the indicator starts to show clipping, any increase beyond this point will only increase the noise. If the power amplifier control knob is set to a high value indiscriminately, the tuner needs to attenuate the signal in the mixer or other audio devices in the signal chain, so this operation will narrow the gap between the output level and the background noise. Therefore, using the power amplifier knob to compensate the low-level signal of the mixer will only increase the noise problem.
同时，如果房间内的音量过大，应该在功放旋钮上控制音量，而不是降低混音器传来的音频信号，以保持良好的信噪比。
At the same time, if the volume in the room is too high, the volume should be controlled on the power amplifier knob instead of reducing the audio signal from the mixer to maintain a good signal-to-noise ratio.
综上所述，可以看出，在整个音响系统的各个组成部分中，保持尽可能高的信号电平，是比较容易实现噪声小，同时输出大功率的方法。在任何情况下，功率放大器都应该静音或关闭，直到功率放大器之前的音响设备组件都获得良好的增益架构。
To sum up, it can be seen that in each component of the whole professional sound system, maintaining the signal level as high as possible is an easy method to achieve low noise and output high power at the same time. In any case, the power amplifier should be muted or turned off until the professional audio equipment components before the power amplifier get a good gain architecture.
