The new EV-5000 is a public address and VA matrix from IC Audio, which operates all necessary supervision-functions for EN60849 in a slim 1 U housing.
You can connect several desktop paging microphones and also use it for emergency announcements via sound files stored on an MMC-flash memory card for easy handling.
Up to ten units can be linked together to control a total of 80 speakers zones, and when used in this way, the EV-5000 will detect and automatically setup all connected units.
