表演舞臺(tái)是音響使用量比較大的場(chǎng)合之一，但是如果
山東舞臺(tái)音響出了問(wèn)題會(huì)直接導(dǎo)致演出無(wú)法順利進(jìn)行。因此，我們須要知道舞臺(tái)音響可能會(huì)遇到一些什么樣的問(wèn)題，下面來(lái)看看吧。
The performance stage is one of the occasions with a large amount of sound usage, but if there is a problem with Shandong stage sound, the performance will not go smoothly. Therefore, we need to know what problems stage acoustics may encounter. Let's take a look.
1線路要按標(biāo)準(zhǔn)連接
1 The line shall be connected according to the standard
常見(jiàn)系統(tǒng)交流干擾聲大就是線路連接工藝沒(méi)有做好造成的，還有系統(tǒng)中有平衡轉(zhuǎn)不平衡及不平衡轉(zhuǎn)平衡接法的務(wù)要按標(biāo)準(zhǔn)連接，另外不要用劣質(zhì)接插件。
Common systems with high AC interference are caused by poor line connection process. In addition, if there are balanced to unbalanced and unbalanced to balanced connections in the system, make sure to connect according to the standard. In addition, do not use inferior connectors.
2調(diào)整壓限器問(wèn)題
2. Adjustment of pressure limiter
常見(jiàn)擺設(shè)根本不起作用和作用過(guò)度起反作用。前者可以將就用，后者則會(huì)帶來(lái)嚴(yán)重影響系統(tǒng)的動(dòng)態(tài)，表現(xiàn)為聲音發(fā)不出來(lái)，明顯表現(xiàn)是伴奏聲越強(qiáng)人聲就自然減弱使演唱者無(wú)所適從。
Common furnishings do not work at all and are counterproductive if they function excessively. The former can be put to use, while the latter will bring about a serious impact on the dynamics of the system, which is manifested in the inability to produce sound. It is obvious that the stronger the accompaniment sound, the weaker the voice will naturally weaken, leaving the singer at a loss.
3信號(hào)分配的問(wèn)題
3 Signal distribution problems
在聲場(chǎng)內(nèi)有幾組揚(yáng)聲器的情況下，常使用一臺(tái)均衡器將信號(hào)分配給多臺(tái)功放推動(dòng)音箱。但同時(shí)也可能是不同企業(yè)型號(hào)的功放和音箱混在一起使用，這樣分配信號(hào)帶來(lái)很多問(wèn)題，阻抗是否匹配，電平分配是否均衡，音箱所獲得功率是否正常，以及用一臺(tái)均衡很難調(diào)整好聲場(chǎng)和音箱的頻率特性。
When there are several groups of speakers in the sound field, an equalizer is often used to distribute the signal to multiple power amplifiers to push the speakers. But at the same time, it may also be that power amplifiers and speakers of different brands and models are used together, which causes many problems in signal distribution, such as whether the impedance matches, whether the level distribution is balanced, whether the power obtained by the speakers is normal, and it is difficult to adjust the frequency characteristics of the sound field and speakers with one equalizer.
4效果回路處理
4 Effect loop treatment
應(yīng)該取推子的后置信號(hào)，避免效果不受控引起話筒嘯叫，返回有條件占用一路通道，這樣調(diào)試更方便。
The rear signal of the pusher should be taken to avoid the microphone howling due to uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging.
5處理低音信號(hào)
5 Process bass signal
一是不做電子分頻用全頻信號(hào)直接給功放推動(dòng)音箱，這樣有聲音也不于燒壞單元，但低單元發(fā)全頻聲音可想而知。如從系統(tǒng)中不恰當(dāng)位置取得信號(hào)也會(huì)給現(xiàn)場(chǎng)控制帶來(lái)不要的麻煩。二是不知從系統(tǒng)何處提取低音信號(hào)做處理。
First, instead of electronic frequency division, the full frequency signal is used to directly push the speaker to the power amplifier, so that the sound will not burn the unit, but it is conceivable that the full frequency sound is generated by the low unit. If the signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the field control. Second, I don't know where to extract bass signal from the system for processing.
對(duì)于舞臺(tái)音響這幾個(gè)方面的故障及時(shí)采取有效的手段來(lái)防止或解決這些問(wèn)題的出現(xiàn)。對(duì)于舞臺(tái)常使用的音響而言，不出問(wèn)題就要提前做好預(yù)防準(zhǔn)備，更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站
