ABSTRACT:
In a playback apparatus which plays back music in a plurality of audio formats, a control unit detects a voltage level of a power supply unit and restricts a playback of music in one of the audio formats, which requires power consumption whose amount exceeds a given value, when the detected voltage level is lower than a threshold value. Alternatively, the control unit restricts a playback of one of a plurality of pieces of music, which requires power whose amount exceeds a given value, when the detected voltage level is lower than a threshold value.
