Audio Priority Input Voiceover Ducking Circuit Module for Commercial Paging Sound Systems, General Public Address

Audio Priority Input Voiceover Ducking Circuit Module for Commercial Paging Sound Systems, General Public Address Description

The variable resistors adjust three parameters respectively.
It 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 volume level of a secondary audio source, like background music, to it's audible for your listeners.
Once Priority signal is no longer present, the other audio source(s) can go back to where they were.
Please note: This circuit cannot be directly connected to a microphone.
