Abstract
A method includes receiving first data associated with a first power amplifier and second data associated with a second power amplifier. The method also includes generating a first amplitude limiting signal having gain parameters that are based on the first data and the second data. The first data includes at least one of a temperature measurement associated with the first power amplifier, a supply voltage measurement associated with the first power amplifier, a load resistance associated with the first power amplifier, or a gain associated with the first power amplifier. The method further includes modifying an audio signal based at least in part on the first amplitude limiting signal to generate a first gain-adjusted audio signal. The method also includes providing a first output audio signal to the first power amplifier for amplification. The first output audio signal is based at least in part on the first gain-adjusted audio signal.
