A method for controlling an audio amplifier unit having an audio input, an amplifier, a volume regulation unit and an audio output. An audio signal is received via the audio input and is amplified by the amplifier, and an adjustment procedure modifies an operating curve of the volume regulation unit for the received audio signal. From a modified setting of the volume regulation unit, a modified amplification value is calculated according to a first volume operating curve. The amplifier's amplification is modified to match the modified amplification value, and a second volume operating curve is determined and assigned to the calculation of modified amplification values of the amplifier. The modified amplification value is substantially at the center of the second volume operating curve. Further, the volume regulation unit is adjusted mechanically or electrically to a predefined position.
