I have two 12 inch 8ohm speaker and I want a circuit diagram of amp having 2 mic input (not electrolet) and also one aux in to give input from devices like mobile etc it should contain preset of spkr vol ,mic vol ,and bass and treble for sound control. I tried a lot but i couldn't get a full circuit diagram of it. They were separate power amp, preamp and other circuit. So, any one can guide me a right way . If possible include pcb. The main thing is i want to play those big speakers clean with mic in and aux in. Hope you understand.
Amplifier circuit diagram needed

Hi Bishal789,
surely you wont get the schematic of the complete setup you require. you could check Elliott sound products website,
however, i could give you the schematic of the power amp and the tone control which I have built.
also what's the power rating of your speakers.

What is the power rating of your speakers?
A single circuit like this is dificult to get. You have got to assemble it as different modules. If you need the mic and aux inputs badly, try reverse engineering the input section of any Ahuja PA amps. As for power amp, Elliot P3A is a good try. It has good sonics and easy to build. for higher power, the leach amp is a good project. it has everything including short circuit protection and all. be in touch. I think I can help you with the PCBs.

There is another way to meet your requirement. find an old Ahuja PA amplifier. it has all these mic, aux inputs, tone controlls etc. rip off the power amp. replace it with a hifi discrete stereo amp. I wud suggest Elliot P3A. you may need to replace/ rewind the power trafo.

You can buy an assembled amp PCB from below link dude....
Lumin - 150 Watts Power AMP Mono
This should be best suiting almost all subwoofers. The transistors used in this have a very high power handling capability.

For excellent sound that won't break the bank, the 5 Star Award Winning Wharfedale Diamond 12.1 Bookshelf Speakers is the one to consider!
