家庭影院音箱系統(tǒng)設備中反饋抑制器的主要作用是防止系統(tǒng)產生反饋，保護揚聲器設備。那么家庭影院音箱系統(tǒng)中設置反饋抑制器的內容是怎樣的？
The main function of feedback suppressor in home theater speaker system equipment is to prevent the system from generating feedback and protect speaker equipment. So what is the content of setting feedback suppressor in the speaker system of home theater?
在使用麥克風抑制反饋點時，找?guī)讉€經常使用的麥克風，在調整的過程中不斷改變麥克風的位置。您也可以在調整過程中放一點背景音樂或對著麥克風說一些話。這樣可以使聲場更加活躍，更有利于準確快速地找到聲反饋頻率。
When using the microphone to suppress the feedback point, find several microphones that are often used, and constantly change the position of the microphone in the process of adjustment. You can also play some background music or speak into the microphone during the adjustment. This can make the sound field more active and help to find the sound feedback frequency accurately and quickly.
如果系統(tǒng)中有壓縮機，注意直接連接壓縮機，調整好后再恢復。系統(tǒng)中的其他音頻處理設備，如混音器、均衡器、激勵器、分頻器、效果器等，應調整到正常工作狀態(tài)。
If there is a compressor in the system, pay attention to directly connect the compressor and restore it after adjustment. Other audio processing equipment in the system, such as mixer, equalizer, exciter, frequency divider, effector, etc., shall be adjusted to normal working state.
注意檢查系統(tǒng)中使用的反饋抑制器對音樂信號和麥克風反饋信號的分辨率。檢測方法是：關閉所有麥克風，將反饋抑制器串聯(lián)在任何有音樂信號的通道上，然后播放一段音樂就好，并不斷提高該通道的音量。如果發(fā)現(xiàn)反饋抑制器開始工作，嚴重影響音質，則證明反饋抑制器并不完善。
Pay attention to check the resolution of the feedback suppressor used in the system to the music signal and microphone feedback signal. The detection method is: turn off all microphones, connect the feedback suppressor in series with any channel with music signal, then play a piece of music, and constantly increase the volume of the channel. If it is found that the feedback suppressor starts to work, which seriously affects the sound quality, it proves that the feedback suppressor is not perfect.
有一點需要特別注意：如果你調整了反饋抑制器，在表演時不要按下Reset按鈕，因為這會你之前設置的所有參數，并重置反饋抑制器。變成了工廠的原始狀態(tài)，非常危險。系統(tǒng)很可能會發(fā)出強烈的嘯叫聲，嚴重時甚會損壞設備。
One thing to note: if you adjust the feedback suppressor, don't press the reset button during the performance, because it will clear all the parameters you set before and reset the feedback suppressor. It has become the original state of the factory, which is very dangerous. The system is likely to emit a strong whistling sound, and even damage the equipment in serious cases.
部分反饋抑制器有自動和手動兩種工作模式可供選擇。如果您認為您的調整很，系統(tǒng)不會產生聲反饋，您可以將反饋抑制器置于手動或鎖定工作模式，這樣既保留了設備中的原始參數，又不改變調整后的參數由于設備的誤檢測和誤啟動。
Some feedback suppressors have two working modes: automatic and manual. If you think your adjustment is perfect and the system will not produce acoustic feedback, you can put the feedback suppressor in manual or locked working mode, so that the original parameters in the equipment are retained and the adjusted parameters are not changed due to the false detection and false start of the equipment.
還有一點，
家庭影院音箱反饋抑制器不能既抑制聲反饋又調節(jié)聲場。要調整聲場，需要專用的模擬多頻段房間均衡器或的數字參量均衡器。
Another point is that the feedback suppressor of the speaker in the home theater can not only suppress the sound feedback but also adjust the sound field. To adjust the sound field, a special analog multi band room equalizer or a professional digital parametric equalizer is required.
