Abstract
An audio amplifier power and temperature controller and associated method are provided which preferably includes a power receiving circuit for receiving power from a power source to an audio amplifier and a power condition switching control circuit responsive to the power receiving means for switching components of an audio amplifier during a plurality of power conditions. The power condition switching control circuit preferably includes a network detecting circuit responsive to the power receiving circuit for detecting network conditions, a thermal status monitoring and controlling circuit for monitoring thermal status of audio amplifier components and responsively decreasing power to the audio amplifier components to protect the audio amplifier components against damage caused by excess heat and for responsively increasing power when the audio amplifier components return to normal thermal operating conditions, and an audio power sensing and processing circuit responsive to the power receiving circuit for monitoring audio power input conditions to the audio amplifier to enhance source output and to reduce or eliminate noise such as due to other components within a network system.
