<p>An audio amplifier may comprise a signal limiting circuit and a power amplifier. The signal limiting circuit may be configured to limit an audio signal received at an input and to provide it as a limited audio signal at an output. The power amplifier may have a supply connection which may be coupled to a power supply unit in order to supply power to the power amplifier. The power amplifier may be configured to amplify a signal, which may be based on the limited audio signal, and to provide it as a level-limited audio signal at an output which may be coupled to a load, so that the load may be operated at limited power. The signal limiting circuit may be configured to produce an audio signal which may be limited depending on the load.</p> |
