[abstract]Along with the people living standard's further enhancement, the acoustic equipment and the family theater system already entered ordinary people's family, the establishment has suited the family theater which one savor no longer was vainly hoped. But the present paper is precisely obtains from the acoustic most basic power amplification electric circuit, has analyzed the integration power amplification electric circuit's basic design method systematically. Thus lets us further complete the entire sound system's design to finish the preparation. But must complete this work also to have many topics to be worth us studying. [key words]Acoustic equipment, family theater, power amplification electric circuit, integration power amplification electric circuit, design method, system.
