山東音響在使用期間并不是說什么問題都不存在，那么為了更好更順利的使用音響，我們來看看問題有哪些吧。
Shandong professional audio does not mean that there are no problems during its use. In order to use the audio better and more smoothly, let's take a look at the problems.
低音信號處理
Bass signal processing
類問題是不進行電子分頻直接使用全頻信號給功放驅動音箱；第二類問題是不知從系統哪里獲取低音信號進行處理。假如不進行電子分頻直接使用用全頻信號給功放推動音箱，雖然音箱能放出聲音也不會損壞音箱單元，但單獨就其低單元發全頻聲音可想而知；但假如從系統中不恰當位置獲取低音信號也會給舞臺音響工程師的臨場操作帶來多余的麻煩。
The first problem is to directly use the full frequency signal to the power amplifier to drive the speaker without electronic frequency division; The second problem is not knowing where to get the bass signal from the system for processing. If the speaker is directly driven by the full frequency signal to the power amplifier without electronic frequency division, although the speaker can emit sound without damaging the speaker unit, it is conceivable that the low unit can emit full frequency sound alone; However, if the bass signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the on-site operation of the stage sound engineer.
線路連接處理
Line connection processing
在音響工程中常見的音響系統交流干擾聲大就是線路連接處理沒到位導致的，還有系統中有平衡轉不平衡及不平衡轉平衡接法，使用時一定符合規范標準。另外，會議舞臺音響中禁止使用劣質接插件。
In professional audio engineering, the loud AC interference of the audio system is caused by the failure of the line connection. There are also balanced to unbalanced and unbalanced to balanced connection methods in the system, which must meet the specifications and standards when used. In addition, it is forbidden to use inferior connectors in professional conference stage audio.
控制問題
Control problems
控制臺是音響系統的控制中心，有時控制臺上的高中低EQ均衡做同等大幅度的提升或衰減則表示音響系統并未設置正確，應該重新調試系統，禁止過分調整控制臺的EQ。
The console is the control center of the audio system. Sometimes, if the high, medium and low EQ equalization on the console is increased or attenuated by the same amount, it means that the audio system is not set correctly, and the system should be re commissioned. Excessive adjustment of the EQ of the console is prohibited.
均衡器的調試問題
Debugging of equalizer
常見均衡器會出現燕子型、山峰型、波浪型三種頻譜波形狀，波形狀都是音響工程師人為想象的譜波形狀，其實并不是音響工程現場實際所需要的譜波形狀，眾所周知，理想的譜波形狀曲線是相對穩定平緩的，假如人為地通過想象調整譜波形狀曲線，可想而知，終效果往往是事與愿違的。
Common equalizers have three kinds of spectral wave shapes: swallow type, peak type and wave type. The wave shape is the spectral wave shape artificially imagined by professional sound engineers, but it is not the spectral wave shape actually required by the sound engineering site. As we all know, the ideal spectral wave shape curve is relatively stable and gentle. If the spectral wave shape curve is artificially adjusted through imagination, it can be imagined that the final effect is often contrary to what you want.
What are the problems during the use of professional audio? The above four questions are what we want to explain. You can follow our website http://www.zkvd.cn Consult.
