Product Details

The PP-250 is a 250 Watt 70V Paging Power Amplifier that can drive up to two hundred fifty (250) 70V speakers and/or paging horns (each speaker set to “1 Watt tap”). The small 1U rack size chassis is possible because the PP-250 uses new amplifier technology that is 3 times more efficient than old designs competitors use. The high efficiency of the PP-250 means much less heat dissipation, smaller size, higher reliability, and lower cost.

There are many advantages of using a 70V distributed audio paging system, such as being able to put more speakers on a wire run, having longer speaker wire runs, using smaller gauge wire, and being able to set the volume of each speaker independently. The PP-250 Line Input can connect to telephone system paging ports, paging mixers, etc.


  • Paging systems requiring 8 to 250 speakers
  • Paging from virtually any analog line level paging source
  • Installations that can utilize the below advantages of a 70V distributed audio system:
    • Longer wire runs using smaller gauge speaker wire to save costs
    • Many speakers can be connected on the same wire run to save costs
    • Set each speaker’s volume individually using its own power tap
