舞台，是一个表演者表演的场地，那些美轮美奂的场景，抑扬顿挫的音响，有源于舞台灯光及音响的功劳，想要表现出精美的表演，对于表演者的追光一定是很重要的，想要表现出东通的声音，那么音响也是非常重要的，下面小编就为大家介绍下
山东舞台灯光音响的使用要避免哪些问题？
The stage is a place for performers to perform. Those beautiful scenes and rhythmic sound are derived from the contributions of stage lighting and sound. If you want to show a beautiful performance, it must be very important for performers to track the light. If you want to show the voice of Dongtong, then sound is also very important. Next, I will introduce to you what problems should be avoided in the use of stage lighting and sound in Shandong?
1、设备外壳有带电现象检查顺序
1. Inspection sequence for electrification of equipment shell
设备外壳带电&谤补谤谤;供电线路是否损坏&谤补谤谤;线路相位是否正确&谤补谤谤;设备接地是否正确&谤补谤谤;使用电压是否正确。
The equipment shell is electrified → whether the power supply line is damaged → whether the line phase is correct → whether the equipment is grounded correctly → whether the voltage is correct.
2、音响系统音量不足
2. The sound system volume is insufficient
设备音量不足&谤补谤谤;功放与音响的线路电平设置是否正确&谤补谤谤;音响线连接是否牢固&谤补谤谤;功放与音响的相位是否一致&谤补谤谤;均衡器衰减幅度是否恰当&谤补谤谤;压限器的起控电平是否恰。
The volume of the equipment is insufficient → whether the line level of the power amplifier and the audio is set correctly → whether the audio cable is firmly connected → whether the phase of the power amplifier and the audio is consistent → whether the attenuation amplitude of the equalizer is appropriate → whether the starting control level of the limiter is appropriate.
3、声场中发生共振和反馈
3. Resonance and feedback in sound field
发生共振和声反馈&谤补谤谤;检查房间频响是否有峰点&谤补谤谤;房间结构和装饰是否合理&谤补谤谤;分频点和低音增益是否合理&谤补谤谤;房间混响时间是否过长。
Resonance and acoustic feedback occur → check whether the room frequency response has peak points → whether the room structure and decoration are reasonable → whether the frequency division point and bass gain are reasonable → whether the room reverberation time is too long.
4、产生干扰噪声
4. Produce interference noise
音响系统有噪声&谤补谤谤;调光干扰&谤补谤谤;音响与灯光电源是否分开&谤补谤谤;灯光电源和控制线路是否离音频信号线太近&谤补谤谤;硅箱是否离音频设备太近。
The audio system has noise → dimming interference → whether the audio and light power supply are separated → whether the light power supply and control circuit are too close to the audio signal line → whether the silicon box is too close to the audio equipment.
音响系统有噪声&谤补谤谤;信号的传输是否合理&谤补谤谤;所有信号线的屏蔽是否恰当&谤补谤谤;信号的接地是否正确&谤补谤谤;所有音频设备的电源相位一致。
The audio system has noise → whether the signal transmission is reasonable → whether the shielding of all signal lines is appropriate → whether the signal grounding is correct → whether the power supply phase of all audio equipment is consistent.
5、灯光失控
5. Lights out of control
灯光失控&谤补谤谤;控制器的程序是否正确&谤补谤谤;灯具的地址编码是否正确&谤补谤谤;控制线的接法是否正确&谤补谤谤;控制线的屏蔽是否不良或受到干扰&谤补谤谤;灯具的限位调整是否恰当&谤补谤谤;灯光供电开关接触是否良好。
The light is out of control → whether the program of the controller is correct → whether the address code of the lamp is correct → whether the connection of the control line is correct → whether the shielding of the control line is poor or disturbed → whether the limit adjustment of the lamp is appropriate → whether the contact of the light power supply switch is good.
6、电脑灯的灯泡经常损坏(750小时)
6. The light bulb of the computer lamp is often damaged (750 hours)
灯泡易坏&谤补谤谤;安装是否牢靠是否沾染尘土和水气&谤补谤谤;灯泡散热是否良好&谤补谤谤;电压是否正常&谤补谤谤;电源开关是否频繁。
The bulb is easy to be damaged → whether it is installed firmly or not contaminated with dust and moisture → whether the bulb has good heat dissipation → whether the voltage is normal → whether the power switch is frequent.
7、视频图象不正常
7. Video image is abnormal
视频图象不正常&谤补谤谤;节目制式是否正确&谤补谤谤;设备外壳是否带电&谤补谤谤;信号屏蔽是否受到高电平干扰&谤补谤谤;投影管是否正常&谤补谤谤;液晶投影的灯泡的性能是否差。
The video image is abnormal → whether the program format is correct → whether the equipment shell is charged → whether the signal shield is subject to high-level interference → whether the projection tube is normal → whether the performance of the LCD projection bulb is poor.
8、无线话筒的声音不稳定
8. The sound of wireless microphone is unstable
声音不稳定&谤补谤谤;系统内是否有高频干扰源&谤补谤谤;天线连接是否正确&谤补谤谤;接收机微调是否正确&谤补谤谤;话筒数量是否超量&谤补谤谤;话筒电池电量不足。
The sound is unstable → whether there is a high-frequency interference source in the system → whether the antenna connection is correct → whether the receiver trim is correct → whether the number of microphones is excessive → whether the battery power of the microphone is low.
