家庭影院音箱系统设备中反馈抑制器的主要作用是防止系统产生反馈,保护扬声器设备。那么家庭影院音箱系统中设置反馈抑制器的内容是怎样的?
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?
在使用麦克风抑制反馈点时,找几个经常使用的麦克风,在调整的过程中不断改变麦克风的位置。您也可以在调整过程中放一点背景音乐或对着麦克风说一些话。这样可以使声场更加活跃,更有利于准确快速地找到声反馈频率。
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.
如果系统中有压缩机,注意直接连接压缩机,调整好后再恢复。系统中的其他音频处理设备,如混音器、均衡器、激励器、分频器、效果器等,应调整到正常工作状态。
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.
注意检查系统中使用的反馈抑制器对音乐信号和麦克风反馈信号的分辨率。检测方法是:关闭所有麦克风,将反馈抑制器串联在任何有音乐信号的通道上,然后播放一段音乐就好,并不断提高该通道的音量。如果发现反馈抑制器开始工作,严重影响音质,则证明反馈抑制器并不完善。
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.

有一点需要特别注意:如果你调整了反馈抑制器,在表演时不要按下Reset按钮,因为这会清除你之前设置的所有参数,并重置反馈抑制器。变成了工厂的原始状态,非常危险。系统很可能会发出强烈的啸叫声,严重时甚至会损坏设备。
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.
部分反馈抑制器有自动和手动两种工作模式可供选择。如果您认为您的调整很完美,系统不会产生声反馈,您可以将反馈抑制器置于手动或锁定工作模式,这样既保留了设备中的原始参数,又不改变调整后的参数由于设备的误检测和误启动。
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.
还有一点,家庭影院音箱反馈抑制器不能既抑制声反馈又调节声场。要调整声场,需要专用的模拟多频段房间均衡器或专业的数字参量均衡器。
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.
家庭影院音箱系统中设置反馈抑制器的内容讲解完毕,当然如果您想更好的使用音箱就要多去了解相关内容,您可以关注我们网站www.wenguangzhineng.com咨询问题。
