送受信機。 A first audible signal having a magnitude corresponding to the difference between the stereo left and right signals; in the low level range of the first audible signal, the first audible signal is expanded by a predetermined magnification, and in the middle and high level range, the first audible signal is and a second audible signal whose level is compressed by decreasing the magnification as the level of the audible signal increases; receiving an FMX stereo broadcast having a main channel consisting of a third audible signal having a corresponding amplitude;
means for demodulating the second and third audible signals; means for obtaining a sum signal of the first audible signal and the second audible signal; and means for level-expanding the sum signal to produce the first audible signal. In the FMX stereo broadcast receiver, the FMX stereo broadcast receiver has means for obtaining a level expanded signal substantially similar to the FMX stereo broadcast signal, and stereo reproduction means for reproducing the stereo left and right signals from the third audible signal and the level expanded signal. level detection means for generating a detection signal when the reception level is below a predetermined level range; An FMX stereo broadcast receiver characterized by reproducing left and right signals.
