The present invention relates to a system and method for improving the efficiency of power consumption of the audio system. To In essence, this technique adjusts the power in response to the detected characteristics of the response to the volume level, and / or an input audio signal represented by the volume control module, the analog section from the power supply part, and passes it to temyeon power amplifier . Thus, in this manner, the analog unit is operated in a manner to affect the level of the signal being processed. Additionally, the systems and methods may also be related to the technique for adjusting the dynamic range of the digital signals and analog signals to improve the overall dynamic range of the system without the need to consume extra power.
