Abstract
An audio amplifier power and temperature controller and associated methods are provided. The controller preferably includes a power receiving circuit positioned to receive power from a power source to an audio amplifier and a power condition switching control circuit responsive to the power receiving circuit to switch components of an audio amplifier during a plurality of power conditions. The power condition switching control circuit preferably includes a soft start circuit responsive to the power receiving circuit to limit inrush current from the power receiving circuit and to slowly ramp up to an audio amplifier on-state and a thermal status monitoring and controlling circuit to monitor thermal status of operating values of audio amplifier components and responsively decrease power to the audio amplifier components to protect the audio amplifier components against damage caused by excess heat and responsively increase power when the audio amplifier components return to normal thermal operating conditions.
