舞台音响灯光的正常与否直接的影响着演出的效果，所以不论什么设备都需要做好保养和维护工作，对出现问题的线路和设备应及时的维修，避免意外情况的出现。而对于酒吧、KTV、歌舞厅等场所来讲，装修过程中，往往会出现这样的情况：音响师辛苦了半天，但是最终的音响效果总是不尽人意，那么究竟该如何去检查设备是否妥善呢？下面小妮就和大家分享一些在音响设备方案设计过程中，实用效果更好的小技巧！
Stage lighting sound is normal or not directly affects the performance of the effect, so no matter what devices need to do maintenance and maintenance work, should be timely maintenance of lines and equipment, to avoid unexpected situations. As for KTV, bars, dance halls and other places, in the decoration process, often happens: the sound engineer is always hard for a long time, but eventually the sound effect is unsatisfactory, so how to check the equipment properly? The next little Ni share with you some in the audio equipment design process, the practical effect of better skills!
设备外壳带电现象的检查顺序
Inspection sequence of electrification phenomenon of equipment shell
设备外壳带电检查的顺序首先是要检查供电线路是否出现损坏的情况，其次是线路相位是否正确，其次还要了解设备接地和电压是否正确。
The order of live inspection of the equipment shell is to check whether the power supply line is damaged or not, the second is whether the line phase is correct, and secondly, to know whether the equipment is grounded and the voltage is correct.
音量不足的情况检查顺序
Check order of insufficient volume
一般情况下如果专业音响设备中出现音量不足的情况，就要及时的检查功放和音箱的线路电平设置是否正确，其次还要了解音箱线连接是否牢固，还有就是功放与音箱的相位是否一致，均衡器衰减幅度是否在正常的范围呢，压限器的起控电平是否恰当。
Generally if the volume shortage appeared in professional audio equipment to check the amplifier and speakers timely line level settings are correct, then understand the speaker wire connection is strong, there is a phase of the amplifier and speakers are the same, whether the failure tolerance equalizer in the normal range, the pressure limiter whether it is appropriate to control level.
检查声场中发生的共振和反馈
Check the resonance and feedback in the sound field
如果在专业音响设备中出现共振和声反馈的情况，首先要检查房间频响是否有峰点，还有就是要检查房间结构和装饰是否合理，最好还要检查分频点和低音增益是否合理，房间混响时间是否出现过长的情况。
If in the case of resonance and acoustic feedback in professional audio equipment, we should first check whether there is room response peak, there is room to check the structure and decoration is reasonable, but also the best check frequency point and low gain is reasonable, whether the reverberation time appeared in the case of long.
产生干扰噪声的检查方法
Inspection method for generating interference noise
专业音响设备中如果有噪声，首先就要检查调光干扰，音响和灯光电源是否出现断开的情况，其次就要检查灯光电源和控制线路是否离音频信号线太近，有没有出现硅箱离音频设备太近的情况。一般情况下出现音箱系统有噪声的情况，通常都是由于信号的传输不合理的情况所导致的，所以当信号线的屏蔽出现问题，或者信号的接地不正确的情况，就容易出现噪声干扰的情况。
Professional audio equipment if there is noise, we must first check whether the light interference, sound and lighting power is disconnected, then check the lighting power supply and control circuit is from the audio signal line too close, there is no silicon box from the audio equipment too near the. In general the speaker system with noise, is usually caused by signal transmission unreasonable situation, so when the signal line shielding problems, grounding or signal is not correct, it is prone to the noise.
音视频系统中对视频图象的检查
Video image checking in audio and video system
如果在专业音响设备中出现视频图象不正常的情况，首先就需要检查节目制式是不是在正确的范围，设备外壳有没有带电的情况，其次还要检查信号屏蔽是不是容易受到高电平干扰，最好要检查投影管是否在正常的范围内，液晶投影的灯泡的性能有没有出现问题。
If there is not a normal video image in professional audio equipment, first you need to check the program format is not in the right range, there is no electric equipment shell, then check the signal shielding is not susceptible to high level interference, it is best to check whether the projection tube in the normal range, the performance of liquid crystal projection the bulb there is no problem.
无线话筒的声音不稳定
The sound of the wireless microphone is unstable
如果无线话筒不稳定的情况，首先就要检查声音不稳定的原因在哪里，是由于系统内有高频干扰源导致的，还是天线连接错误、接收机微调、话筒电池电量等连接设备出现问题导致的。
If the wireless microphone is not stable, the reason we must first check the sound unstable where is due to system in high frequency interference source to the receiver or antenna connection error, trimming, microphone battery power and other connected devices caused by problems.
希望今天带来的技巧能够帮助大家解决实际中遇到的困难，技巧固然重要，但是最重要的是拥有一颗仔细的心，就能将设备的性能全部发挥出来，使整个音响系统达到预期效果！
I hope today brings skills to help solve the practical difficulties, skills are important, but the most important is to have a careful heart, will all play out the performance of the equipment, make the whole sound system to achieve the desired effect!
