PURPOSE:To obtain an amplifier of high fidelity by obtaining a bit of information corresponding to an input signal by processing the digital signal fetched according to the necessity by following a fixed program and reproducing and amplifying the input signal based thereon. CONSTITUTION:The digital signal fetched according to the necessity is processed by the digital signal processing circuit performing the processing according to preset program to obtain the bit of information corresponding to the inputted signal. And based on this information, the input signal is reproduced and amplified. An audio amplifier of high fidelity can thus be realized and the variation in action point due to temp., i.e., temp. drift can be restrained to the utmost as well. Even in the case of a stereoscopic amplifier, the right and left balances can easily be kept.
