PURPOSE: An amplifier circuit and a method for compensating voltage thereof are provided to supply a realistic acoustic sound by transmitting voltage for the optimum operation of an amplifier to an amplifier circuit. CONSTITUTION: A temperature sensor(31) measures the temperature of an amplifier circuit. An amplifier(33) amplifies the temperature detection signal measured in the temperature sensor to a prescribed amount. A controller(35) receives the temperature detection signal amplified in the amplifier and outputs a bias control signal. The controller measures secondary side voltage in an electric transformer and separates the measured secondary side voltage into a prescribed step. A transistor bias controller(37) outputs bias voltage . |
