1.系統(tǒng)電平問題:是功放靈活度控制開關(guān)翻開缺乏,其次系統(tǒng)沒有做零電平調(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。
1. System level problem: firstly, the power amplifier flexibility control switch is not turned on, and secondly, 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.
2低音信號處置:一種不做電子分頻用全頻信號直接給功放推進(jìn)音箱;二種不知從系統(tǒng)何處提取低音信號做處置。假設(shè)不做電子分頻用全頻信號直接給功放推進(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)位置獲得信號也會(huì)給現(xiàn)場控制帶來不用要的費(fèi)事。
2 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 push the speaker directly to the power amplifier. Although the speaker has sound, it won't burn the unit, but it's incredible to send full frequency sound to 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.
3.效果回路處置:應(yīng)該取推子的后置信號,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)。
3. Effect loop disposal: the post signal of the pusher should be taken to prevent the microphone from howling due to uncontrolled effect, and return to occupy a channel conditionally, so that debugging is more convenient.

4.線路銜接工藝:常見系統(tǒng)交流干擾聲大就是線路銜接工藝沒有做好形成的,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。
4. Line connection process: the loud AC interference of common systems is that 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.
5.控制問題: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),不要過火調(diào)整調(diào)音臺(tái)的EQ。
5. Control problem: the mixer is the control center of the system. Sometimes, if the high, medium and low EQ balance on the mixer is increased or attenuated by the same large margin, it indicates that the system has not been adjusted well, and the system needs to be re debugged. Do not over adjust the EQ of the mixer.
