Here is my circuit : http://i.imgur.com/lKVvEWB.png
The original idea was mixing 2 audio using 741 with 3 band equalizer. But I change the IC to 386, adding mic as input, 6 band equalizer, power amp to make sure there is enough supply to the speaker, also others enhancement. Any idea to make the circuit works better, with less noise to make it sound better? Or any other idea that I can add to this project. Thanks.

The LM386 is the wrong IC here. It is a (low power) power amp, not a preamp. Redesign using TL072, TL082 or NE5532, Also, draw your schematic using the standard triangle symbol to make reading it easier. E

Thanks for the input. I must be misunderstand about op amp. Because i though low power gonna produce less noise. For the design, since there is no LM386 in multisim component list, thats why its not triangle symbol. Im gonna redesign it using NE5532
@JonSnell Electronic
Thanks, I miss that part.
Also, is it needed to put more capacitor to get rid of DC component? Where to put it if its needed?
