Impact i-Controller, the brain and network hub of Impact MM Voice Alarm System. Thanks to enabled Ethernet ports and MAZE engine installed, the i-Controller has direct access to 250 audio channels transmitted within the MAZE network. i-Controller can receive simultaneously 2 BGM channels over IP, while the standard analogue BGM inputs are still available. Signal from local analogue BGM inputs can be also simultaneously broadcasted by i-Controller to the LAN, to be received by amplifiers and other i-Controllers .
