任何一套優良的
多媒體會議音響系統,都離不開音響工程人員的辛勤勞動,不論是音響的擺放位置的,還是調音。在工程施工中總是會遇到這樣或者是那樣的問題,針對這些問題,下面總結了幾點,希望對大家有所幫助。
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:在多媒體會議室音響工程中對于電平問題,要檢查是不是功放的靈敏度操控開關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整。因為有時在調音臺通道推一點點輸出,就會產生很大的輸出,在這種情況下就會直接的影響體系的動態和失真度。
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:是一種常見體系交流干擾聲大,出現這種情況大多數都是由于線路銜接技術沒有做到位引起的,對于體系中有平衡轉換不平衡,或者是不平衡轉換平衡的接法通常都要按規范銜接。
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、信號分配方面的問題:如果在聲場內有幾組揚聲器,用一臺均衡器分配信號,就容易給分配信號的過程帶來很多的麻煩,因為阻抗的匹配與否,點評分配的均衡與否等,在一臺均衡器上面運用都很難好各個音箱的頻率和聲場。
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:對于這種情況的處理方法可以取推子的后置信號,就能有效的防止話筒嘯叫,如果在回來有條件的情況下可以占用一路通道,從而方便調試。
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、多媒體會議室音響工程中的圖示均衡器的頻點調整問題:頻點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,但是在實際的運用中聲場并不需求波形,因為聲場頻率特性曲線一般情況下都是相對平整的,如果將其調整為聲場頻率特性曲線,就會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、低聲信號處置:不僅需要選擇恰當的信號獲取位置,也需要設置好功放的功率。避免出現燒壞等情況。
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、壓限器調整問題:常用的方法有存在的問題是,鋪排底子過度不僅會引起反作用,還會引起音響發不出聲音的情況出現。
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.
此外多媒體會議室音響工程中的調音臺是體系的操控中心,如果出現調音臺上的高中低EQ均衡做平等大幅度的晉升,或是衰減,對于這種問題需求可以從頭調試體系,但是不要過火調整調音臺的EQ。更多相關內容就來我們網站

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.
