舞臺(tái)，是一個(gè)表演者表演的場(chǎng)地，那些美輪美奐的場(chǎng)景，抑揚(yáng)頓挫的音響，有源于舞臺(tái)燈光及音響的功勞，想要表現(xiàn)出精美的表演，對(duì)于表演者的追光一定是很重要的，想要表現(xiàn)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(tái)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(shè)備外殼有帶電現(xiàn)象檢查順序
1. Inspection sequence for electrification of equipment shell
設(shè)備外殼帶電→供電線路是否損壞→線路相位是否正確→設(shè)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(tǒng)音量不足
2. The sound system volume is insufficient
設(shè)備音量不足→功放與音響的線路電平設(shè)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(dāng)→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(chǎng)中發(fā)生共振和反饋
3. Resonance and feedback in sound field
發(fā)生共振和聲反饋→檢查房間頻響是否有峰點(diǎn)→房間結(jié)構(gòu)和裝飾是否合理→分頻點(diǎn)和低音增益是否合理→房間混響時(shí)間是否過(guò)長(zhǎng)。
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(chǎn)生干擾噪聲
4. Produce interference noise
音響系統(tǒng)有噪聲→調(diào)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(hào)線太近→硅箱是否離音頻設(shè)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(tǒng)有噪聲→信號(hào)的傳輸是否合理→所有信號(hào)線的屏蔽是否恰當(dāng)→信號(hào)的接地是否正確→所有音頻設(shè)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(diào)整是否恰當(dāng)→燈光供電開關(guān)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(jīng)常損壞(750小時(shí))
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(guān)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(jié)目制式是否正確→設(shè)備外殼是否帶電→信號(hào)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(wú)線話筒的聲音不穩(wěn)定
8. The sound of wireless microphone is unstable
聲音不穩(wěn)定→系統(tǒng)內(nèi)是否有高頻干擾源→天線連接是否正確→接收機(jī)微調(diào)是否正確→話筒數(shù)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.
