In a method and by an apparatus for correction of error signals and for forming of an arbitrary transfer function being independent of the quality of a payload (loudspeaker; H1) included in a signal amplification system, a control system (9) is used for supplying of the input signal to a basic amplifier (1) driving the payload. Said control unit includes a further amplifier (9) having an inverted input being supplied with a feedback signal from the output of the basic amplifier. In such a case the further amplifier involves only an inverted input, said input signal is supplied through one (4) of the resistors (3, 4) included in the feedback loop.
An apparatus for correction of error signals and for forming of an arbitrary transfer function being independent of the quality of a driven payload having a first terminal connection and a second terminal connection in a signal amplification system, said apparatus comprising a control unit having at least one input and an output, and a basic amplifier having a non-inverting and an inverting input and an output, wherein
