在為客戶做
山東音響工程施工的過程中總會遇到各種各樣的難題，為此小編專門地總結(jié)了一些常見的問題介紹給各位，以下是具體的內(nèi)容：
During the construction of Shandong professional audio engineering for customers, there are always various difficulties. For this reason, the editor specially summarizes some common problems and introduces them to you. The following is the specific content:
1.壓限器調(diào)整問題
1. Pressure limiter adjustment
在音響工程中常見壓限器調(diào)整問題是壓限器根本不起作用或作用過度反而導(dǎo)致反作用。前者問題發(fā)生后仍可將就使用，后者問題發(fā)生則會導(dǎo)致嚴(yán)重影響音響工程系統(tǒng)的運作，具體表現(xiàn)通常為表現(xiàn)是伴奏聲越強(qiáng)人聲就越弱使表演者無所適從。
The common problem of pressure limiter adjustment in professional audio engineering is that the pressure limiter does not work at all or acts excessively, which leads to reaction. The former can still be used after problems occur, while the latter will seriously affect the operation of the sound engineering system. The specific performance is usually that the stronger the accompaniment sound, the weaker the human voice, making the performers at a loss.
2.效果回路處理
2. Effect loop treatment
應(yīng)該取推子的后置信號，避免效果失控而導(dǎo)致的話筒嘯叫現(xiàn)場，返回有條件的話可以占用一路通道，如此調(diào)整起來更加容易。
The post signal of the fader should be taken to avoid the microphone howling caused by the out of control effect. If conditions permit, one channel can be occupied, so it is easier to adjust.
3.信號分配的問題
3. Signal distribution
在音響工程項目內(nèi)設(shè)置有幾組揚聲器的情況下，一般通過一臺均衡器將信號分發(fā)給多臺功放與音箱。但同時也導(dǎo)致各種企業(yè)型號的功放與音箱混合使用，這樣分發(fā)信號可能導(dǎo)致各種問題，例如阻抗是否吻合、電平分配是否平均、各組音箱所獲得功率是否達(dá)標(biāo)等，另外用一臺均衡很難調(diào)整好聲場和音箱的頻率特性。
When several groups of loudspeakers are set in the professional audio engineering project, the signal is generally distributed to multiple power amplifiers and speakers through one equalizer. However, at the same time, it also leads to the mixed use of power amplifiers and speakers of various brands and models. In this way, the distribution of signals may lead to various problems, such as whether the impedance is consistent, whether the level distribution is average, and whether the power obtained by each group of speakers is up to standard. In addition, it is difficult to adjust the sound field and the frequency characteristics of speakers with one equalizer.
4.系統(tǒng)電平調(diào)整問題
4. System level adjustment
功放靈敏度控制旋鈕沒有到位，接著是音響系統(tǒng)沒有執(zhí)行零電平調(diào)整。某些時候調(diào)音臺通道稍微向上推聲音輸出就增大很多，這種情況會影響音響系統(tǒng)的正常運營和保真度。
The power amplifier sensitivity control knob is not in place, and then the audio system does not perform zero level adjustment. In some cases, the sound output will increase a lot when the mixer channel is pushed up slightly, which will affect the normal operation and fidelity of the audio system.
The four common problems of professional audio engineering are the contents explained above. You can take it as a reference to see how to prevent problems and better use them. For more related content, please visit our website http://www.gulfbaader.com Consult and understand!
