PURPOSE: An individual control method of a speaker is provided to determine whether a speaker line is short by receiving a signal transmitted from a vector generator according to a control signal of a computer. CONSTITUTION: An amplifier(20) and speakers(60,61,62,...) are connected through a plurality of relays(70,71,72...). The relays(70,71,72...) are connected to a microcontroller(50). A test vector generator(50) is connected between the microcontroller(30) and the relays(70,71,72...) to transmit a control signal of the microcontroller(30) to the relays(70,71,72...) and generate a clock. The microcontroller(30) is connected to a 232C distributor(80) by an RS232C line(81) for a smooth communication. A computer(40) includes a program for controlling a speaker(60) and transmits a control signal sent in a GUI(Graphic User Interface) environment to the 232C distributor(80).
