This auto-paging mixer features 3 RCA phono type stereo/audio inputs, all with their own volume control. It also has a master volume and 4-band tone control section. It also has Priority line and Priority Mic inputs.

Connect the jukebox to the stereo Priority Line Input and it will automatically override and mute the selected audio input when the music kicks in and ramp that input back up when the jukebox is done. An internal jumper allows you to switch off the ducking feature to one output side only. This allows you to keep the background music constant in the dining room while still ducking and paging in the waiting area. The MPM1 is housed in a 1U steel chassis with removable rack ears.
