Audio Enhancement MS-500 Networked Amplifier

The Audio Enhancement MS-500 is a networked classroom amplifier and a central component in the Optimum Classroom System. This amplifier has network-based intercom, paging, and emergency notification, providing full-duplex audio. It is easy-to-use, easy-to-install, and has simple user interface software. The entire unit is Powered over Ethernet (PoE). Intercom and paging functionalities are built-in. During emergencies, paging can still be heard, even when the power goes out. This unit can be installed as part of the SAFE (Signal Alert For Education) System.
