Fuhjythy Commercial Paging Audio Ducking Circuit Board for Public Address Systems & General Sound Management

It is often used in commercial paging sound systems, general public address applications, and live events. Once the Priority signal is no longer present, the other audio source(s) can go back to where they were. The variable resistors adjust three parameters respectively. 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 it's audible for your listeners. Please note: This circuit cannot be directly connected to a microphone.
