Abstract:
1. A method for regulating an amplifier system temperature T(n) of an amplifier system, where the amplifier system comprises a volume control unit for inputting a listener's volume level setting V(n), a temperature sensing unit for measuring the amplifier system temperature T(n), a power amplifier unit having an adjustable gain G(n), and a controller connected to the volume control unit, the temperature sensing unit, and the power amplifier unit, the method comprising: receiving the volume level setting V(n) from the volume control; transmitting the amplifier system temperature T(n) from the temperature sensing unit to the controller; assessing whether the amplifier system temperature T(n) is greater than a gain regulation temperature T adjusting the gain G(n) of the power amplifier unit to a target gain level determined by the volume setting V(n) if the amplifier system temperature T(n) is below the gain regulation temperature T using historical values of the amplifier system temperature T(n) for calculating the target gain G(n) of the power amplifier unit if the amplifier system temperature T(n) is above the gain regulation temperature T
