AMAHALU IKENNA
Presented To
Department of Electrical/Electronic Engineering
ABSTRACT
The design of this 30 volt Audio Amplifier with volume, table and bass control which was done wit ht he combination of five (5) different circuit which are interconnected during or after construction. This amplifier operates with an option of a left and right channel.
The combination of these circuit include this main amplifier circuit (which consist of a left and right channel, two treble and bass pre – amp circuit and the power supply circuit.
The main amplifier circuit consist of an interpreter circuit (IC) and lots of resistors, electrolytic capacitor with few a mp circuit of a transistor with some resistors and paper capacitor.
The power circuit which is used to power all the circuit 6f a 30 volt step down transformer, double rectification circuit, with 2 diodes and capacitor (Electrolyic). This amplifier when constructed, can produce up to 800 watts (w) of audio signal. It can be sued to amplify the sound of audio sound system like mini radio cassette player, compact disc player, turn table record player, car radio cassette player or any other sound system that requires increased audio.
This amplifier when produced in large or commercial quality, according to purpose will create job opportunity, provide indigenous electronics technology industry, and it will contribute to economic growth of the nation.
