音響工程是一個比較大的工程,在安裝中要注意,而且音響工程安裝中有很多的問題,音響工程中常見問題的解決方法有哪些呢?下面
山東音響廠家為您解答。
Sound engineering is a relatively large project. Attention should be paid to during installation. There are many problems in the installation of sound engineering. What are the solutions to common problems in sound engineering? Next, Shandong audio manufacturer will answer for you.
1.信號分配的問題:在聲場內(nèi)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(yè)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(diào)整好聲場和音箱的頻率特性。
1. Signal distribution: When there are several groups of speakers in the sound field, one equalizer is often used to distribute the signal to multiple power amplifiers to drive 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.
2.均衡器的頻點調(diào)整問題:其實理想的聲場頻率特性曲線應(yīng)該是相對平坦的,如果人為憑想象調(diào)整聲場頻率特性曲線,可想而知其結(jié)果是事與愿違。
2. Frequency adjustment of the equalizer: In fact, the ideal sound field frequency characteristic curve should be relatively flat. If you adjust the sound field frequency characteristic curve by imagination, you can imagine that the result is contrary to your expectations.
3.壓限器調(diào)整問題:常見是做擺設(shè)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(tǒng)的動態(tài),表現(xiàn)為聲音發(fā)不出來,明顯表現(xiàn)是伴奏聲越強人聲就自然減弱使演唱者無所適從。
3. Adjustment problem of pressure limiter: the common problem is that the equipment does not work at all and the excessive action is counterproductive. 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.
4.系統(tǒng)電平問題:是功放靈敏度控制開關(guān)打開不足,其次系統(tǒng)沒有做零電平調(diào)整。有時調(diào)音臺通道推一點點輸出已很大,這種情況會影響系統(tǒng)的動態(tài)和失真度。
4. System level problem: First, the sensitivity control switch of the power amplifier is not open enough, and then the system does not make zero level adjustment. Sometimes the output of the mixer channel is very large after pushing a little bit, which will affect the dynamics and distortion of the system.
5.低音信號處理:假如不做電子分頻用全頻信號直接給功放推動音箱雖然音箱有聲音也不于燒壞單元,但就其低單元發(fā)全頻聲音可想而知;但如果從系統(tǒng)中不恰當位置取得信號也會給現(xiàn)場控制帶來不必要的麻煩。
5. Bass signal processing: If we don't do electronic frequency division, we can use full frequency signal to directly push the power amplifier. Although there is sound in the speaker, it will not burn the unit, but we can imagine that its low unit will emit full frequency sound; But if the signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the field control.
6.效果回路處理:應(yīng)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(diào)試更方便。
6. Effect loop processing: the post signal of the pusher should be taken to avoid the microphone howling caused by uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging.
7.線路連接工藝:常見系統(tǒng)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(tǒng)中有平衡轉(zhuǎn)不平衡及不平衡轉(zhuǎn)平衡接法的一定要按標準連接。另外不要用劣質(zhì)接插件。
7. Line connection process: common system AC interference is caused by poor line connection process, and the system with balanced to unbalanced and unbalanced to balanced connection must be connected according to the standard. In addition, do not use inferior connectors.
8.控制問題:調(diào)音臺是系統(tǒng)的控制中心,有時調(diào)音臺上的高中低EQ均衡做同等大幅度的提升或衰減則說明系統(tǒng)并未調(diào)好,需要重新調(diào)試系統(tǒng),不要過分調(diào)整調(diào)音臺的EQ。
8. Control problem: The mixer is the control center of the system. Sometimes, if the high, medium and low EQ balance on the mixer is raised or attenuated by the same margin, it means that the system is not well adjusted, and the system needs to be re debugged. Don't over adjust the EQ of the mixer.
此外要注意,音響器材用完后,各功能鍵要復位。如果功能鍵長期不復位,其牽拉鈕簧長時期處于受力狀態(tài),就容易造成功能失常,所以相關(guān)額使用注意事項要了解到,您可以來我們網(wǎng)站

In addition, it should be noted that the function keys should be reset after the audio equipment is used up. If the function key is not reset for a long time, its pull button spring is under stress for a long time, which is likely to cause functional disorder.
