Basic audio amplifier circuit diagram. This amplifier circuit can deliver 150 watt rms. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. It is probably the one of the easiest audio amplifiers to build. It is actually a dual audio power amplifier that is designed specifically for very good quality stereo applications.
Find out how to build a great sounding audio amplifier with bass boost from the lm386 ic and learn what makes this amplifier sound better than the rest. Tda2009 is used in amplifier. Tda2009 ic is a hi fi class ab stereo amplifier in multiwatt package. Let me show you.
This stereo amplifier circuit diagram is cheap and simple. 4 channel portable audio mixer high quality modular design 9v battery powered very low current drawing the target of this project was the design of a small portable mixer supplied by a 9v pp3 battery keeping high quality performance. This is a low cost 150 watt amplifier circuit with diagram and schematic design using two darlington power transistors tip 142 and tip 147. This is a very useful and simple circuit diagram for amplifying weak signal from a capacitive condenser microphoneyou can use this circuit for sound sensing applications and some automatic robotic sensorswe have already posted an efficient audio amplifier circuit using 1895 ic it is somewhat complicated and is suitable for very sensitive applications.
