Pojačavač PMX-2P500 klase D je profesionalno audio pojačalo snage 2x500W/100V za glasovne sisteme za evakuaciju. Može se napajati iz električne mreže i iz jednosmernog pomoćnog napajanja. Izlazni signal je galvanski izolovan i neprestano se nadgleda za spoj prema masi. Režim štednje energije i brzina ventilatora kontrolisana temperaturom smanjuju potrošnju energije i nivo buke. Funkcije upravljanja i nadzora pojačavača izvršavaju se preko sistemske CAN magistrale. Ovo pojačalo je dizajnirano za rad u sistemu za hitnu evakuaciju. Pojačala se obično kontrolišu preko centralnog audio kontrolera i konfigurišu pomoću IRISNet-a.
Pojačalom upravlja procesor i opremljen je velikim brojem funkcijama nadzora. Nadgledanje CAN magistrale i signalne audio linije omogućava otkrivanje i ukazivanje prekida na liniji i kratkih spojeva korisniku, a sve po EN54-16 standardu.
