Abstract

An amplifier arrangement for amplifying an audio input signal AES into an audio output signal AAS, having a conditioning apparatus for converting the audio input signal AES into a conditioned intermediate signal ZS. The conditioning apparatus includes an audio input interface for accepting the audio input signal and a digital data processing device. The amplifier arrangement also includes an amplifier apparatus for amplifying the intermediate signal ZS into the audio output signal AAS and the amplifier apparatus has at least one operating voltage BS. The amplifier arrangement also includes a limiting module for limiting the audio output signal AAS by changing a gain parameter VK.
