任何一套優(yōu)良的
多媒體會(huì)議音響系統(tǒng)，都離不開音響工程人員的辛勤勞動(dòng)，不論是音響的擺放位置的，還是調(diào)音。在工程施工中總是會(huì)遇到這樣或者是那樣的問題，針對(duì)這些問題，下面總結(jié)了幾點(diǎn)，希望對(duì)大家有所幫助。
Any set of excellent multimedia conference sound system can not be separated from the hard work of sound engineers, whether it is the placement of sound or tuning. There are always problems in one way or another in the construction of the project. In view of these problems, the following is a summary of a few points, hoping to help you.
1、體系電平問題：在多媒體會(huì)議室音響工程中對(duì)于電平問題，要檢查是不是功放的靈敏度操控開關(guān)翻開缺乏的情況造成，其次在檢查一下體系中有沒有做零電平調(diào)整。因?yàn)橛袝r(shí)在調(diào)音臺(tái)通道推一點(diǎn)點(diǎn)輸出，就會(huì)產(chǎn)生很大的輸出，在這種情況下就會(huì)直接的影響體系的動(dòng)態(tài)和失真度。
1. System level problem: For the level problem in the multimedia conference room sound engineering, first check whether the sensitivity control switch of the power amplifier is not turned on, and then check whether the system has zero level adjustment. Because sometimes pushing a little output on the channel of the mixer will produce a large output, which will directly affect the dynamics and distortion of the system in this case.
2、線路銜接技術(shù)：是一種常見體系交流干擾聲大，出現(xiàn)這種情況大多數(shù)都是由于線路銜接技術(shù)沒有做到位引起的，對(duì)于體系中有平衡轉(zhuǎn)換不平衡，或者是不平衡轉(zhuǎn)換平衡的接法通常都要按規(guī)范銜接。
2. Line connection technology: It is a common system with high AC interference. Most of the reasons are that the line connection technology is not in place. The connection method with balanced or unbalanced conversion in the system should be connected according to the specifications.
3、信號(hào)分配方面的問題：如果在聲場(chǎng)內(nèi)有幾組揚(yáng)聲器，用一臺(tái)均衡器分配信號(hào)，就容易給分配信號(hào)的過(guò)程帶來(lái)很多的麻煩，因?yàn)樽杩沟钠ヅ渑c否，點(diǎn)評(píng)分配的均衡與否等，在一臺(tái)均衡器上面運(yùn)用都很難好各個(gè)音箱的頻率和聲場(chǎng)。
3. The problem of signal distribution: if there are several groups of speakers in the sound field and a single equalizer is used to distribute the signal, it is easy to bring a lot of trouble to the process of signal distribution, because it is difficult to use the frequency and sound field of each speaker on a single equalizer because of the matching of impedance and the balance of comment distribution.
4、作用回路處置：對(duì)于這種情況的處理方法可以取推子的后置信號(hào)，就能有效的防止話筒嘯叫，如果在回來(lái)有條件的情況下可以占用一路通道，從而方便調(diào)試。
4. Action loop disposal: for this case, the post-signal of the pusher can be taken to effectively prevent the microphone from whistling. If it is possible to return, one channel can be occupied, which is convenient for debugging.
5、多媒體會(huì)議室音響工程中的圖示均衡器的頻點(diǎn)調(diào)整問題：頻點(diǎn)問題我們比較常見的有燕子型、山峰型、波濤型三種頻譜波型狀，但是在實(shí)際的運(yùn)用中聲場(chǎng)并不需求波形，因?yàn)槁晥?chǎng)頻率特性曲線一般情況下都是相對(duì)平整的，如果將其調(diào)整為聲場(chǎng)頻率特性曲線，就會(huì)引起適得其反的效果。
5. The problem of frequency adjustment of graphic equalizer in multimedia conference room sound engineering: We usually have three kinds of spectral wave shapes: swallow type, peak type and wave type. However, in practical application, the sound field does not need waveform, because the frequency characteristic curve of the sound field is generally relatively flat. If we adjust it to the frequency characteristic curve of the sound field, it will cause the opposite effect.
6、低聲信號(hào)處置：不僅需要選擇恰當(dāng)?shù)男盘?hào)獲取位置，也需要設(shè)置好功放的功率。避免出現(xiàn)燒壞等情況。
6. Low-sound signal processing: not only need to select the appropriate signal acquisition location, but also need to set the power of the power amplifier. Avoid burning.
7、壓限器調(diào)整問題：常用的方法有存在的問題是，鋪排底子過(guò)度不僅會(huì)引起反作用，還會(huì)引起音響發(fā)不出聲音的情況出現(xiàn)。
7. Pressure limiter adjustment problem: The common method has the problem that the excessive laying of the substrate will not only cause reaction, but also cause the situation that the audio system cannot produce sound.
此外多媒體會(huì)議室音響工程中的調(diào)音臺(tái)是體系的操控中心，如果出現(xiàn)調(diào)音臺(tái)上的高中低EQ均衡做平等大幅度的晉升，或是衰減，對(duì)于這種問題需求可以從頭調(diào)試體系，但是不要過(guò)火調(diào)整調(diào)音臺(tái)的EQ。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站

In addition, the mixer in the sound engineering of multimedia conference room is the control center of the system. If the EQ balance of the high, middle and low EQ on the mixer is promoted or attenuated by an equal margin, the system can be adjusted from scratch, but the EQ of the mixer should not be adjusted too much.
