Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system and method of improving the efficiency in the power consumption of an audio system.SOLUTION: The system and method improves the efficiency by reducing power consumption in an audio system by adjusting the power supplied to an audio power amplifier 206-L by a power supply 212 for an analog section via a power supply control module 214 on the basis of a volume level indicated by a volume control module 216 and/or an envelope of an input audio signal. 【課題】オーディオシステムの電力消費における効率を改善するシステム及び方法を提供する。【解決手段】入力オーディオ信号の包絡線及び／又はボリューム制御モジュール２１６によって指示されるボリュームレベルに基づいて電源制御モジュール２１４を介して、アナログセクション用電源２１２によりオーディオ電力増幅器２０６−Ｌに供給される電力を調整することによってオーディオシステムにおける電力消費を減少させ、効率を改善する。【選択図】図２
