ABSRACT - [ Total Page(s): 1 ]It has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM†is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sound energy to electrical energy, the energy electrical signal being transmitted is been received and ampli

CHAPTER ONE - [ Total Page(s): 3 ]In this project, the audio amplifier used is capable of delivering 20watts continuously. The term “power amplifier†is a relative term with respect to the amount of power delivered to the load and/or sourced by the supply circuit.In general a power amplifier is designated as the last amplifier in a transmission chain (the output stage) and is the amplifier stage that typically requires most attention to power efficiency. Power amplifiers have also become lighter, smaller, more powerful and more efficient due to increasing use of Class A amplifiers, which offer signi ... Continue Reading
