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?
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.
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.
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.
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.
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.
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.
