PROBLEM TO BE SOLVED: To provide a control signal transmission/reception system that conducts stereophonic transmission of an audio signal including control information with a canceling effect in a hearing sense upon monaural reproduction maintained.SOLUTION: A portable information terminal 100 is configured to transmit a signal obtained by modulating control signal from a stereophonic left channel; and cause a phase to be inverted with respect to the signal; and transmit a signal obtained by modulating a phase difference correction value causing a phase difference between an error-correcting code of the control signal and the control signal to be converged from stereophonic right channel. An electronic music instrument 200 receiving these signals is configured to conduct monaural reproduction of monaural audio data obtained by synthesizing the signal subjected to sampling and stored in a buffer. Because of synthesis of a signal holding a phase inversion state in a 2-bit modulation unit, the monaural audio data is configured to maintain a canceling effect in a hearing sense upon monaural reproduction.SELECTED DRAWING: Figure 1
