舞台音响灯光的正常与否直接的影响着演出的效果,那么,我们对舞台灯光音响设备使用的同时,也需要我们对它定期的检查,检查有哪些常识要知道呢?
Whether the stage sound and lighting are normal or not directly affects the performance effect. So, when we use the stage light and lighting equipment, we also need to check it regularly. What common sense should we know?
电脑灯灯泡损坏检查
Inspection for damage of computer lamp bulb
在
山东舞台灯光音响中很容易出现的就是灯泡易坏的情况,所以出现问题,就要检查安装的灯泡否牢靠,有没有沾染尘土和水气,还有就是要检查灯泡的散热是不是在正常范围内,很好需要检查的是电压是否在正常的范围内,有没有使用电源开关过于频繁的情况。
In Shandong stage lighting and audio, it is easy to see that the bulb is easy to break. Therefore, if there is a problem, it is necessary to check whether the installed bulb is reliable, whether it is contaminated with dust and moisture, and whether the heat dissipation of the bulb is within the normal range. It is good to check whether the voltage is within the normal range and whether the power switch is used too frequently.
音响系统中音量不足的情况检查顺序
Inspection sequence of insufficient volume in professional audio system
一般情况下如果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。
In general, if the volume of professional audio equipment is insufficient, it is necessary to timely check whether the line level setting of the power amplifier and the speaker is correct. Secondly, it is necessary to know whether the speaker line is firmly connected, whether the phase of the power amplifier and the speaker is consistent, whether the attenuation of the equalizer is within the normal range, and whether the starting control level of the voltage limiter is appropriate.
怎么检查声场中发生共振和反馈
How to check resonance and feedback in the sound field
如果在音响设备中出现共振和声反馈的情况,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,很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 resonance and acoustic feedback occur in professional audio equipment, first of all, it is necessary to check whether there is a peak in the room frequency response, whether the room structure and decoration are reasonable, and whether the frequency division point and bass gain are reasonable, and whether the room reverberation time is too long.
产生干扰噪声的检查方法
Inspection method for generating interference noise
音响设备中如果有噪声,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。
If there is noise in professional audio equipment, first check whether the dimming interference, audio and light power supply are disconnected, and then check whether the light power supply and control line are too close to the audio signal line, and whether the silicon box is too close to the audio equipment. In general, the noise in the speaker system is usually caused by unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal grounding is incorrect, noise interference is likely to occur.
