A ROMstores a plurality of volume set values and a plurality of level change rates corresponding to each other and an ICaccepts a volume set value specified by a user when carrying out volume setting. Moreover, it is decided whether a reproducing object is a CD or a DVD depending on a decision signal output from a loader sectionA level change rate corresponding to the volume set value is output to an ICif the reproducing object is the DVD, and the level change rate corresponding to the volume set value is adjusted at a predetermined adjusting rate and the level change rate thus adjusted is output to the ICif the reproducing object is the CD. The ICchanges the level of an analog signal indicative of a voice input from the loader sectionat the level change rate and outputs the signal to an amplifying circuit
