音響做為音響的終端設備器械，好像人的嗓子，在非常大水平上決策了一套音響的優(yōu)劣。能夠不浮夸地說：挑選一對好的音響是一套音響取得成功的根本所在，容不得一點兒粗心大意。下面來講講有關
山東舞臺燈光音響常見知識。
As the terminal equipment of the sound system, the sound system is like a human voice, which decides the advantages and disadvantages of a sound system at a very large level. It can be said without exaggeration that selecting a pair of good stereos is the root of the success of a set of stereos, and no carelessness is allowed. Now let's talk about the common professional knowledge of Shandong stage lighting and sound.
1、設備機殼有感應起電狀況查驗次序
1. Inspection sequence of inductive power on condition of equipment casing
設備機殼感應起電—供電系統(tǒng)路線是不是毀壞—路線相位差是不是恰當--設備接地裝置是不是恰當—應用工作電壓是不是恰當
Inductive electrification of equipment enclosure - whether the power supply system line is damaged - whether the line phase difference is appropriate - whether the equipment grounding device is appropriate - whether the working voltage is appropriate
2、音響系統(tǒng)聲音不夠
2. The sound of the audio system is not enough
會議舞臺音響設備聲音不夠—功放機與音響的路線脈沖信號設定是不是恰當—音響線聯接是不是堅固—功放機與音響的相位差是不是一致—均衡器衰減系數力度是不是適當—壓限器的起控脈沖信號是不是恰
The sound of the audio equipment on the conference stage is not enough - is the route pulse signal of the power amplifier and the audio set properly - is the audio line connected firmly - is the phase difference between the power amplifier and the audio consistent - is the attenuation coefficient strength of the equalizer appropriate - is the starting pulse signal of the pressure limiter appropriate
3、音場中產生共震和意見反饋
3. Co shock and feedback in sound field
產生共震和弦意見反饋—查驗屋子頻率響應是不是有峰點—屋子構造和裝飾設計是不是有效—分音器點和底音增益值是不是有效—屋子混響時間是不是太長。
Generate common shock chord feedback - check whether the room frequency response has a peak point - whether the room structure and decoration design are effective - whether the splitter point and bottom tone gain value are effective - whether the room reverberation time is too long.
4、造成干擾噪音
4. Causing interference noise
音響系統(tǒng)有噪音—變光干擾—音響與燈光開關電源是不是分離—燈光開關電源和操縱路線是不是離模擬信號線太近—硅箱是不是離聲頻設備太近
The sound system has noise - dimming interference - is the sound and light switch power separated - is the light switch power supply and control route too close to the analog signal line - is the silicon box too close to the audio equipment
音響系統(tǒng)軟件有噪音—數據信號的傳送是不是有效—全部電源線的屏蔽掉是不是適當—數據信號的接地裝置是不是恰當—全部聲頻設備的開關電源相位差一致
Sound system software has noise - is data signal transmission effective - is all power lines shielded properly - is the grounding device of data signal appropriate - is the phase difference of switching power supply consistent for all audio equipment
5、燈光無法控制
5. Light cannot be controlled
音響燈光設計方案，燈光無法控制—控制板的程序流程是不是恰當—照明燈具的詳細地址編號是不是恰當—控線的接線方法是不是恰當—控線的屏蔽掉是不是欠佳或遭受干擾—照明燈具的限位開關調節(jié)是不是適當—燈光供電系統(tǒng)電源開關觸碰是不是優(yōu)良。
In the sound and light design scheme, the light cannot be controlled - is the program flow of the control panel appropriate - is the detailed address number of the lighting fixture appropriate - is the wiring method of the control line appropriate - is the shielding of the control line poor or disturbed - is the limit switch adjustment of the lighting fixture appropriate - is the touch of the power switch of the light power supply system excellent.
