The PA-20M is very compact amplifier specifically designed for fixed or mobile applications. Their small size and light weight make easy their integration in little space. The 12V DC operation perfectly fits for portable use or for installations where direct AC power supply is not available. They are an ideal solution for zoning, information points, ticketing counters and vehicles using rooftop speaker system. Both amplifiers feature a MP3 player with a UBS port, plus a siren triggered with a push button from the front panel. 2 Mic inputs are available with TRS 6.35mm jacks, plus 1 Aux stereo input on the rear panel with RCA connectors. All volume controls are on the front panel and it includes a simple EQ setting. On the rear panel there is also a DC connector ø5.5 / ø1.5mm for connecting the input supply voltage 12V to 15V/DC and terminals for connecting a load with an impedance of 4Ω. The amplifier includes a switched power supply 230V AC / 15V DC / 2A.
