Abstract
The disclosed audio amplifier arrangement includes a first amplifier stage for influencing the signal strength of the received audio signal for at least part of the frequency spectrum of an audio signal received through an input. An output amplifier stage amplifies the signal influenced by the first amplifier stage. A detection present in the output amplifier stage detects overloads of the output amplifier stage (3). A control circuit causes, in response to the detection signal, an adjustment to be made of the influence caused by the first amplifier stage if the overload signalled by the detection signal transgresses a certain limit. This limit depends on the magnitude of the adjustment already carried out, so that the degree of overload corresponding to the limit increases when the extent of the adjustment increases.
