          實際上,公共廣播音響的使用應該要考慮到會出現的問題現象等,所以就要求在使用之前盡量做好相關的調整工作,那么公共廣播音響音頻處理設備的調整是怎樣的?
          In fact, the use of public broadcasting audio should take into account the problems and phenomena that may occur, so it is required to do a good job in the relevant adjustment before using, so how is the adjustment of public broadcasting audio processing equipment?
          房間均衡器有兩個功能:一是調節音質,彌補大廳混響時間引起的頻率響應不平衡;另一個重要功能是降低某個頻帶,減少由聲反饋引起的嘯叫。房間應平衡至音響工程調試期間設置的位置。
          The room equalizer has two functions: one is to adjust the sound quality, to compensate for the frequency response imbalance caused by hall reverberation time; Another important feature is to reduce a certain frequency band, reducing the noise caused by acoustic feedback. The room should be balanced to the position set during sound engineering commissioning.
          在音頻工程中,電壓限制器也是一種重要的設備。其功能是:第一,壓縮或限制節目的動態范圍,防止過載或失真,保護功放和揚聲器;另一個重要功能是提高節目的響度(通過聽覺可以明顯感覺到)。限壓器的調整數據如下:
          Voltage limiter is also an important equipment in audio engineering. Its functions are: first, compress or limit the dynamic range of the program, prevent overload or distortion, protect the power amplifier and loudspeaker; Another important function is to increase the loudness of the program (which can be clearly felt by hearing)。 The adjustment data of the voltage limiter is as follows:
          噪聲門:當指示燈亮時,噪聲門關閉,起消聲作用。當輸入信號下降到閾值水平時,它開始關閉,噪聲門通常位于打開和-20dB之間。
          Noise door: when the indicator is on, the noise door is closed and plays the role of muffling. When the input signal drops to the threshold level, it begins to close, and the noise gate is usually between open and -20dB.
          壓縮閾值級別閾值:確定壓縮開始的級別。它通常設置為-10到0dB。壓縮開始時,增益降低,增益(DB)指示燈開始亮起(3)壓縮比:設置為2:1(4)動作時間攻擊:設置為10ms(5)釋放時間釋放:設置為0.3s。
          Compression threshold Level Threshold: Specifies the level at which compression starts. It is usually set to -10 to 0dB. When compression starts, the gain decreases and the gain (DB) indicator starts to turn on. (3) Compression ratio: 2:1. (4) Action time attack: 10ms. (5) Release time Release: 0.3s.
          山東公共廣播音響公司提醒您,如今數字混響器得到了廣泛的應用。許多不同的混響效果在這樣的機器中固化。調諧器應嘗試一個接一個地演唱和聆聽所用混響器的各種混響效果,錄制可用的節目,并在調諧過程中隨時用鍵盤調出。
          Shandong public broadcasting audio company reminds you that digital reverberator has been widely used nowadays. Many different reverberation effects are solidified in such machines. Tuners should try to sing and listen to the various reverberation effects of the mixer used one by one, record available programs, and call them up with the keyboard at any time during tuning.
          公共廣播音響音頻處理設備的調整相關內容便是以上這樣了,當然您如果是新手的話建議還是需要有專業的人員指導,這樣才能更好的調整音響的綜合情況。更多信息了解就來網站www.jmsslc.com吧。
          The relevant content of the adjustment of public broadcasting audio processing equipment is the above, of course, if you are a novice, you still need to have professional guidance, so as to better adjust the overall situation of sound. For more information, visit www.jmsslc.com.
