舞台音响器材都是一些精密的电子产物，在使用过程中一不小心会很容易损坏设备，设备与设备之间使用了各种规格的音频线连在一起，其中某一根线出现问题可能整套系统都无法运行，下面
山东音响小编介绍舞台音响出现没有声音的故障怎么办。
The stage audio equipment are all sophisticated electronic products, which can easily be damaged if you are not careful in the process of use. Various specifications of audio cables are used between the equipment and the equipment, and the whole system may not work if there is a problem with one of the cables. Next, the small editor of East Professional Audio introduces what to do if there is no sound in the stage audio.
一、检查音响设备有没有问题。
1、 Check the audio equipment for problems.
检查音响设备有没有问题，我们可以从音箱起根据信号传输方向一直检查到调音台;一套完整的舞台音响都有很多音箱和功放，我们可以一步一步找出是音箱、功放、音响周边设备是那台出现问题，如果设备没有问题可以检查一下线路。
Check whether there is any problem with the audio equipment. We can check from the professional speaker to the mixer according to the signal transmission direction; A complete set of stage audio has many professional speakers and professional power amplifiers. We can find out which one has problems with the speakers, power amplifiers and audio peripheral equipment step by step. If there is no problem with the equipment, we can check the circuit.
二、检查线路有没有问题
2、 Check whether there is a problem with the circuit
舞台音响系统中的音频传输线长时间使用会出现老化、脱焊等各种问题，可以先把音量开到小，用手碰到线接头那里，音响系统中会发出难听的声音，这种方法可能会损坏设备，好的方法是用万用表测量线路是否有问题。
The audio transmission line in the stage audio system will have various problems such as aging and desoldering after being used for a long time. You can turn the volume down first, touch the line connector with your hand, and the audio system will emit unpleasant sound. This method may damage the equipment. A good method is to use a multimeter to measure whether the line is faulty.
叁、设备和线路没有问题检查音频输入源电脑
3、 There is no problem with the device and line Check the audio input source computer
如果排除了舞台音响器材和线路都没有问题，那么肯定是输入源的问题，比如电脑，测试是不是电脑出现故障非常简单，将音频线插入手机播放音乐就可以知道是否是电脑的问题了。
If there is no problem with the stage audio equipment and circuits, it must be the problem of the input source, such as the computer. It is very simple to test whether the computer is faulty. If you plug the audio cable into the mobile phone to play music, you can know whether it is the problem of the computer.
