PROBLEM TO BE SOLVED: To reproduce a recording medium, on which digital audio signals are recorded, at high S/N when a microphone is not to be used even while the S/N of a signal path for microphone is not high. SOLUTION: This device is provided with a D/A converter 7 for converting the digital audio signal read from a recording medium 1 into an analog audio signal and an audio signal resulting from adding a microphone audio signal sent from a microphone 2 to the analog audio signal is generated. In this case, a switch circuit 21 for interrupting the introduction of a signal component of a signal path 12 for microphone to an adding point 24, where the analog audio signal and the microphone audio signal are added, is provided on the signal path 12 for microphone for guiding the microphone audio signal to the adding point 24 and when the microphone 2 is not used, the connection of the switch circuit 21 is opened so that the interruption can be performed.
