Esser RK-MCU / HN-PTT INTEVIO Master Control Unit and Push-to-Talk Microphone

This master control unit is at the center of the INTEVIO voice announcement and evacuation system; it manages, supervises, and directs all connected devices and announcements. Its integrated 500 W digital amplifier directly powers eight speaker lines; zone expanders are added when capacity is insufficient. Audio recording, time-scheduled broadcasting, and fault diagnostics are integrated in a single unit. Even if the processor fails, general announcements can be made using the push-to-talk microphone.
