PURPOSE:To shorten a time to a reproduced state by supplying a source voltage to a digital acoustic source device until the mechanism part of the digital acoustic source device is returned to an initial state even when a tuner is selected even during the reproduction or the sound recording of the digital acoustic source device. CONSTITUTION:When it is detected that the mechanism part 6 of the digital acoustic source device is brought into the initial state by a detecting means 11, at the time of selecting the digital acoustic source device by a selecting means 1, a control circuit 13 turns a power source supply circuit 12 on. When the tuner is selected by the selecting means 1 at the same time, the power source supply circuit 12 is turned off. When it is detected that the mechanism part 6 of the digital acoustic source device is brought into the initial state by the detecting means 11, the power source supply circuit 12 is turned on irrespective of the selection of the selecting means 1. Thereby, during the reproduction or the sound recording of the digital acoustic source device, even when the tuner is selected, the source voltage is successively supplied to the digital acoustic source device until the mechanism part of the digital acoustic source device is returned to the initial state.
