A remote controlling system for a public address sound system is provided to perform selective broadcasting in the whole area or a designated area to manage the public address sound system optimally. A remote controlling system for a public address sound system includes a plurality of amps(300), a plurality of speakers(400), a sound source generating unit(10), a matrix switch(30), a testing apparatus(50), a control computer(90), and a controlling apparatus(70). The matrix switch connects the output of the sound source generating unit with the combination of at least one amp and the speaker. The testing apparatus is electrically connected with the amps and the speakers, and tests the amps and the speakers. The control computer sets the combination of the amp and the speaker according to the input information of a broadcasting menu, and generates a connection control signal of the combination of the amp and the speaker according to the setting. The controlling apparatus transmits an output signal of the testing apparatus to the control computer, and drives the matrix switch according to the connection control signal of the combination of the amp and the speaker of the control computer. The broadcasting setting menu of the control computer includes a broadcasting menu and a sub broadcasting menu. The broadcasting menu includes morning broadcasting, lunch broadcasting, finishing broadcasting, and emergency broadcasting. The sub menu includes broadcast state check, broadcast state change, broadcast subscription, broadcasting by grades, and overall broadcasting. When the broadcast state check or the broadcast state change is selected, the testing apparatus is driven and detects the states of the amp and the speaker which are displayed on the control computer. When the emergency broadcasting is selected, the predetermined channel is put in the first priority. |
