舞臺，是一個表演者表演的場地，那些美輪美奐的場景，抑揚頓挫的音響，有源于舞臺燈光及音響的功勞，想要表現出精美的表演，對于表演者的追光一定是很重要的，想要表現出東通的聲音，那么音響也是非常重要的，下面小編就為大家介紹下
山東舞臺燈光音響的使用要避免哪些問題？
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、設備外殼有帶電現象檢查順序
1. Inspection sequence for electrification of equipment shell
設備外殼帶電→供電線路是否損壞→線路相位是否正確→設備接地是否正確→使用電壓是否正確。
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、音響系統音量不足
2. The sound system volume is insufficient
設備音量不足→功放與音響的線路電平設置是否正確→音響線連接是否牢固→功放與音響的相位是否一致→均衡器衰減幅度是否恰當→壓限器的起控電平是否恰。
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、聲場中發生共振和反饋
3. Resonance and feedback in sound field
發生共振和聲反饋→檢查房間頻響是否有峰點→房間結構和裝飾是否合理→分頻點和低音增益是否合理→房間混響時間是否過長。
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、產生干擾噪聲
4. Produce interference noise
音響系統有噪聲→調光干擾→音響與燈光電源是否分開→燈光電源和控制線路是否離音頻信號線太近→硅箱是否離音頻設備太近。
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.
音響系統有噪聲→信號的傳輸是否合理→所有信號線的屏蔽是否恰當→信號的接地是否正確→所有音頻設備的電源相位一致。
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、燈光失控
5. Lights out of control
燈光失控→控制器的程序是否正確→燈具的地址編碼是否正確→控制線的接法是否正確→控制線的屏蔽是否不良或受到干擾→燈具的限位調整是否恰當→燈光供電開關接觸是否良好。
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、電腦燈的燈泡經常損壞(750小時)
6. The light bulb of the computer lamp is often damaged (750 hours)
燈泡易壞→安裝是否牢靠是否沾染塵土和水氣→燈泡散熱是否良好→電壓是否正常→電源開關是否頻繁。
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、視頻圖象不正常
7. Video image is abnormal
視頻圖象不正常→節目制式是否正確→設備外殼是否帶電→信號屏蔽是否受到高電平干擾→投影管是否正常→液晶投影的燈泡的性能是否差。
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、無線話筒的聲音不穩定
8. The sound of wireless microphone is unstable
聲音不穩定→系統內是否有高頻干擾源→天線連接是否正確→接收機微調是否正確→話筒數量是否超量→話筒電池電量不足。
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.
What problems should be avoided in the use of stage lighting and sound? We have explained the following questions from eight aspects. If you have any doubts or needs, please come to our website http://www.zkvd.cn Ask!
