ABSTRACT
Abstract: This paper describes the design and construction of 300W audio power amplifier for classroom. In the construction of this amplifier, microphone preamplifier, tone preamplifier, equalizer, line amplifier, output power amplifier and sound level indicator are included. The output power amplifier is designed as O.C.L system and constructed by using Class B among many types of amplifier classes. There are two types in O.C.L system _ quasi system and complementary system. Between them, the complementary system is used in the construction of 300W audio power amplifier. The Multisim software is utilized for the construction of audio power amplifier.
