The utility model provides a microphone signal controlling means based on reactor control stick actuating mechanism, including remote control terminal and local control end, the local control end is connected with microphone signal on the reactor control stick actuating mechanism, is divided into four subregions with the microphone signal on the excellent actuating mechanism of reactor control according to quadrant etc. And each subregion is a corresponding connection connector respectively, each connector divide into nine groups with microphone signal according to SA, SB, SC, SD, R, N2, N1, G2 and G1 according to the quadrant that it belonged to, remote control terminal and local control serve and are equipped with the corresponding rotary switch with nine above -mentioned components group respectively, correspond through knob switch selection and divide into groups. The realization is to the control of microphone, and every connector corresponds the fourth reactor core, and each is organized the signal and all follow fourth reactor core symmetry and draw, makes respectively to organize the signal and defer to reactor core power exhibition plain then, avoids each to appear a certain or a few microphone single measurement in dividing into groups and leads to reactor core power inequality.
