Eight local audio inputs can be switched to four audio outputs. A two channel message manager is integrated. The controller provides all the audio processing, supervision and control functions for a complete PAVIRO system. A single controller supports up to 100 priorities, 16 call stations and 492 paging zones; up to 8000 fault, warning and event conditions can be logged. The controller is equipped with 12 zones, 18 GPIs and 19 GPOs. One controller can handle up to 2000 W loudspeaker load. Additional zones and power can be added by using up to 20 external routers and 40 amplifiers with each 2 x 500 W.\u003c\/p\u003e\n\u003ch2\u003eProduct Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePublic address and emergency sound system control unit\u003c\/li\u003e\n\u003cli\u003eControl and routing of 4 simultaneous audio channels\u003c\/li\u003e\n\u003cli\u003eOne controller supports 12 zones, expandable up-to 492 zones with 24-zone routers\u003c\/li\u003e\n\u003cli\u003eFour controllers can be networked using OMNEO interface module\u003c\/li\u003e\n\u003cli\u003eEN 54-16 system certification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003ch4\u003eElectrical\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eAudio:  8 audio inputs, 4 audio outputs\u003c\/li\u003e\n\u003cli\u003eSafety\/redundancy:  Internal supervision, system monitoring, watchdog, fault output\u003c\/li\u003e\n\u003cli\u003ePC configuration and control software:\n\u003cul\u003e\n\u003cli\u003eConfiguration Wizard: Easy system configuration.\u003c\/li\u003e\n\u003cli\u003eIRIS-Net: Integration of controller, amplifiers, call stations, routers and peripheral control;
