摘要
According to the present invention circuit means and method are provided which correct for variations in an amplifier load such as a speaker by sensing the load current, developing a feedback signal related to the load current, comparing this feedback signal with the amplifier program, and instantaneously adjusting the gain of the amplifier to compensate for load current deviations from the program applied to the amplifier. By this means the performance of the speaker or other load that is driven by the amplifier is positively controlled and forced to track accurately with the program applied to the amplifier despite such opposing factors as reactance or inertia of the load, whereby the acoustic or other load response is a substantially accurate reproduction of the program.
