1.信號(hào)分配的問(wèn)題：在聲場(chǎng)內(nèi)有幾組揚(yáng)聲器的狀況下，常運(yùn)用一臺(tái)平衡器將信號(hào)分配給多臺(tái)功放推進(jìn)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同運(yùn)用，這樣分配信號(hào)帶來(lái)很多問(wèn)題，阻抗能否匹配，電平分配能否平衡，音箱所取得功率能否正常，以及用一臺(tái)平衡很難調(diào)整好聲場(chǎng)和音箱的頻率特性。
1. Problem of signal distribution: when there are several groups of speakers in the sound field, a balancer is often used to distribute the signal to multiple power amplifier propulsion speakers. But at the same time, it may also be that power amplifiers of different brands and models are used together with speakers. In this way, the distribution of signals brings many problems, such as whether the impedance can be matched, whether the level distribution can be balanced, whether the power obtained by speakers can be normal, and it is difficult to adjust the frequency characteristics of sound field and speakers with a balance.
2.平衡器的頻點(diǎn)調(diào)整問(wèn)題：常見(jiàn)有燕子型山峰型波浪型三種頻譜波型狀，以上波形都是調(diào)音師人為想象的圖形，其實(shí)并不是聲場(chǎng)實(shí)踐需求的波形，
山東音響廠家認(rèn)為理想的聲場(chǎng)頻率特性曲線應(yīng)該是相對(duì)平整的，假如人為憑想象調(diào)整聲場(chǎng)頻率特性曲線，不可思議其結(jié)果是適得其反。
2. Frequency point adjustment of balancer: there are three common spectrum wave shapes: swallow type, peak type, wave type. The above waveforms are artificially imagined by the tuner. In fact, they are not the waveforms required by the sound field practice. Shandong sound manufacturers believe that the ideal sound field frequency characteristic curve should be relatively flat. If the sound field frequency characteristic curve is artificially adjusted by imagination, the result is counterproductive.
3.壓限器調(diào)整問(wèn)題：常見(jiàn)是做擺設(shè)基本不起作用和作用過(guò)度起反作用。前者能夠湊合用，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)者聲就自然削弱使演唱者無(wú)所適從。
3. Adjustment of pressure limiter: common problems are that the decoration basically does not work and the excessive action has a reaction. The former can be used together, while the latter will seriously affect the dynamics of the system, which shows that the sound cannot be emitted. It is obvious that the stronger the accompaniment sound is, the sound will naturally weaken, making the singer at a loss.
4.系統(tǒng)電平問(wèn)題：功放靈活度控制開(kāi)關(guān)翻開(kāi)缺乏，其次系統(tǒng)沒(méi)有做零電平調(diào)整。有時(shí)調(diào)音臺(tái)通道推一點(diǎn)點(diǎn)輸出已很大，這種狀況會(huì)影響系統(tǒng)的動(dòng)態(tài)和失真度。
4. System level problem: the flexibility control switch of the power amplifier is not turned on, and then the system does not make zero level adjustment. Sometimes the output of the mixer channel is very large by pushing a little, which will affect the dynamics and distortion of the system.
5.低音信號(hào)處置：一種不做電子分頻用全頻信號(hào)直接給功放推進(jìn)音箱；二種不知從系統(tǒng)何處提取低音信號(hào)做處置。假設(shè)不做電子分頻用全頻信號(hào)直接給功放推進(jìn)音箱固然音箱有聲音也不于燒壞單元，但就其低單元發(fā)全頻聲音不可思議；但假如從系統(tǒng)中不恰當(dāng)位置獲得信號(hào)也會(huì)給現(xiàn)場(chǎng)控制帶來(lái)不用要的費(fèi)事。
5. Bass signal processing: a kind of full frequency signal directly to the power amplifier propulsion speaker without electronic frequency division; Second, I don't know where to extract the bass signal from the system for processing. Suppose we don't do electronic frequency division and use full frequency signal to directly push the loudspeaker to the power amplifier. Although the loudspeaker has sound, it won't burn the unit, but it's incredible to send full frequency sound on its low unit; However, if the signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the field control.
6.效果回路處置：應(yīng)該取推子的后置信號(hào)，防止效果不受控惹起話筒嘯叫，返回有條件占用一路通道,這樣調(diào)試更便當(dāng)。
6. Effect loop disposal: the post signal of the pusher should be taken to prevent the uncontrolled effect from causing the microphone to scream, and the return conditionally occupies a channel, so that debugging is more convenient.
7.線路銜接工藝：常見(jiàn)系統(tǒng)交流干擾聲大就是線路銜接工藝沒(méi)有做好形成的，還有系統(tǒng)中有均衡轉(zhuǎn)不均衡及不均衡轉(zhuǎn)均衡接法的一定要按規(guī)范銜接。另外不要用劣質(zhì)接插件。
7. Line connection process: common system AC interference is loud because the line connection process is not well formed. In addition, if there are balanced to unbalanced and unbalanced to balanced connection methods in the system, it must be connected according to the specifications. In addition, do not use inferior connectors.
8.控制問(wèn)題：調(diào)音臺(tái)是系統(tǒng)的控制中心，有時(shí)調(diào)音臺(tái)上的高中低EQ平衡做同等大幅度的提升或衰減則闡明系統(tǒng)并未調(diào)好，需求重新調(diào)試系統(tǒng)，不要過(guò)火調(diào)整調(diào)音臺(tái)的EQ。
8. Control problem: the mixer is the control center of the system. Sometimes the high, medium and low EQ balance on the mixer is increased or attenuated by the same magnitude, which indicates that the system is not adjusted well. It is necessary to re debug the system and do not adjust the EQ of the mixer too much.
