PURPOSE:To obtain easily acoustic effect by adding a delay signal, by mixing an analog voice demodulating signal and a digital voice demodulating signal in the ratio of a prescribed signal level, and reproducing said mixed signal. CONSTITUTION:An analog sound signal of the first sound signal line 3 is mixed by a signal mixer 10 to a digital voice demodulating output signal line 5, namely, a delay signal line through an attenuator circuit for executing an adjustment to a prescribed signal level. This mixed sound signal is inputted as the third voice output to a sound signal switching circuit 6 together with the first and the second voice outputs, and a desired reproducing signal is selected by a switching signal 8. Accordingly, an analog sound signal and a digital sound signal are recorded in the same source, and also, if the contents of the source of both the sound signals are the same, the digital sound signal side has a delay time T against the analog voice, therefore, by a circuit by the attenuator 9 and the signal mixer 10, a sound signal output having a delay effect acoustically is obtained.
