Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system and method of improving the efficiency in power consumption of an audio system.SOLUTION: The method adjusts a power supplied from a power supply to an analog section, such as a power amplifier, in response to a volume level indicated by a volume control module and/or in response to the detected characteristic of the input audio signal. In this method, the analog section is operated in a manner that is related to a level of a signal to be processed. Additionally, the system and method also adjust dynamic ranges of a digital signal and an analog signal to improve the overall dynamic range of the system without needing to consume additional power.
