Monacor PA-324 amplifier


The Monacor PA-312 is a single zoned 120W 100V Mixer Amplifier suited for background music & public address applications in small commercial environments.

The amp has 3x microphone inputs for paging/announcements, and 2x aux inputs for directly connecting any smartphone/tablet, or external media player for music playback.

Microphone input 1 has a 'priority circuit' meaning it will override all of the other inputs, lowering the volume of the music so the speech announcement can be clearly heard. The volume dip can also be adjusted.

A telephone input is located on the rear of the amp for connecting to an analogue telephone system. 

The PA-312 has speaker outputs for 100V, 4ohm, 8ohm, and 16ohm speakers.


Key features include:

  • 1 x 120 W
  • 3 microphone inputs, one of which is a balanced input
  • Mic 1 with priority circuit and adjustable automatic talkover
  • 2 aux inputs
  • 1 telephone input for telephone systems with audio output
