表演舞臺是音響使用量比較大的場合之一，但是如果
山東舞臺音響出了問題會直接導致演出無法順利進行。因此，我們須要知道舞臺音響可能會遇到一些什么樣的問題，下面來看看吧。
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線路要按標準連接
1 The line shall be connected according to the standard
常見系統交流干擾聲大就是線路連接工藝沒有做好造成的，還有系統中有平衡轉不平衡及不平衡轉平衡接法的務要按標準連接，另外不要用劣質接插件。
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調整壓限器問題
2. Adjustment of pressure limiter
常見擺設根本不起作用和作用過度起反作用。前者可以將就用，后者則會帶來嚴重影響系統的動態，表現為聲音發不出來，明顯表現是伴奏聲越強人聲就自然減弱使演唱者無所適從。
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信號分配的問題
3 Signal distribution problems
在聲場內有幾組揚聲器的情況下，常使用一臺均衡器將信號分配給多臺功放推動音箱。但同時也可能是不同企業型號的功放和音箱混在一起使用，這樣分配信號帶來很多問題，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，以及用一臺均衡很難調整好聲場和音箱的頻率特性。
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
應該取推子的后置信號，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
5 Process bass signal
一是不做電子分頻用全頻信號直接給功放推動音箱，這樣有聲音也不于燒壞單元，但低單元發全頻聲音可想而知。如從系統中不恰當位置取得信號也會給現場控制帶來不要的麻煩。二是不知從系統何處提取低音信號做處理。
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.
