Known types of amplifiers include so-called class D amplifiers, which first use a pulse-width modulator to convert an analog signal into a pulse-width modulated switching signal, which is then amplified and subsequently converted back into a continuously variable voltage via a filter. This type of amplifier is particularly energy-efficient and is therefore preferably used for high-power amplifiers. The invention relates to an amplifier device 1 comprising a control device (5), wherein the control device (5) has an input interface for an audio signal (2), and comprising an amplifier unit (9) for amplifying the audio signal (2, 8) downstream of the control device (5), wherein the control device (5) has a delay module (6) that is designed to transmit the audio signal (2), delayed by a delay value delta_t, to the amplifier unit (9) and to automatically and/or autonomously reduce the delay value delta_t from a starting value delta_t to a final value during an adaptation phase AP.
