【発明の名称】オーディオ信号再生装置における自動音量制御方法および該方法を実施するための装置
Document Type and Number:
Japanese Patent JP2001519108
Kind Code:
A
Abstract:
An arrangement and a method for automatically controlling the volume in an audio signal reproduction device. A digital signal processing circuit, which is arranged in the audio signal path for influencing the audio signal anyway, is used to reduce the reproduction volume in the event of an overdrive condition of the power amplifier. The overdrive condition is indicated by an overdrive signal attained by the power amplifier. In the process, the decrease and increase in the volume is carried out using various time constants, and disturbing control oscillations are neutralized by inserting a counter which must be decremented prior to a raising of the volume.
