Abstract
An input signal from an audio system is divided into a plurality of frequency bands, and the signal in each frequency band is attenuated by an attenuator. The output signals of the attenuators are added. A level of the signal in each frequency band is detected by a level detector. A memory is provided for feeding an attenuation dependent on a level detected by the level detector. A controller is provided for controlling a signal attenuation of the attenuator by an attenuation fed from the memory in accordance with a detected level.
