SEMI Digital PA system SEMI Digital PA system

Semi Digital PA system adds control and communication function to the essential equipment of existing analog privilege of broadcasting, which realizes school broadcasting’s multi-function. According to social trend, we developed it by compensating equipment control and operation condition monitoring as PC management program for building requesting integrated operation. In the case that there is not PC program, you can conveniently use it by initial setup value.
