The PM3180 ProMatrix Digital Amplifier from Bogen has 3 channels of amplification with 100, 60 and 20W of power for restaurant, lounge/bar hotel, factory or similar facilities where multiple program and paging inputs need to be distributed to separate areas and automatically switched. Priority levels can be assigned at 6 levels. Three integrated amplifiers have separate 4-8 ohms and 25-70V outputs. Each channel has inserts for external signal processing as well. The PM3180 has a plethora of features such as phantom power and automatic level control for microphones, plus automatic fade-in of audio source after a mic page or when switching to a lower priority. The front panel functions can operated up to 25' away with available data cord or use the remote control for programming away from the main unit.
