三个可调电阻功能说明：
①：灵敏度，麦克风音量需要多大才可以触发闪避；
②：恢复时间，当麦克风停止说话时，恢复到正常播放背景音乐的的时间；
③：压限深度，当麦克风说话时闪避开始工作，背景音乐的声音大小压低的程度，可以完全静音，也可以适当保留一些。
Function: When the microphone detects speech, it lowers the volume of background music. It automatically returns to normal when the speaking stops.
is often used in commercial paging sound systems, general public address applications, and live events. It can be used for everything from paging, announcements, or messages to automated emergency alerts or anything that needs a priority source to lower the volume level of a secondary audio source, like the background music, to ensure it's audible for your listeners. Once the Priority signal is no longer present, the other audio source(s) can go back to where they were.

Explanation of the Three Adjustable Resistors' Functions
① Sensitivity: The minimum microphone volume required to trigger the ducking effect.
② Recovery Time: The time it takes for the background music to return to its normal playback volume after the microphone stops receiving input.
③ Depth: The degree to which the background music volume is reduced when the ducking effect activates (i.e., when the microphone is in use). This can range from complete muting of the background music to retaining a moderate level of it.
