Thesis Abstract

<p> </p><p>High power amplifier are usually quite costly and usually beyond the easy reach of most audio enthusiastic (and Hi-Fi &nbsp;buffs) who then have to remain satisfied with those small 6 watt amplifiers. Well, with this introduction to us and to electronics, things should change. Well this low cost Hi-Fi amplifier that delivers ear chatting and thundering output of an unbelievable forty watts. The unique features of this circuit are.</p><div><ul><li>Low cost – The basic criteria </li><li>Compact size</li><li>Very low transient noise on “power on” and low THO</li><li>Effective Bass and treble controls</li><li>Automatic thermal shut down system it switches off the amplifier in case of overheating</li><li>Load damp protection in built.</li></ul></div><p>The circuit uses a high power amplifier chip viz the LA 4440. the circuit is quite self explanatory. The input is coupled by a small value capacitor. The output is taken through a block terminal and fed to the speaker.</p> <br><p></p>
