LED equalizer update (LM386 not good)
Hey, I've read a bit more about LM386 and it seams, that it is too weak, to drive a bigger than a speaker for headphones (or you'll gonna get bad quality sound) which in my case, I did. I could'nt figure out why was it so bad especially with increase gain. So the lesson of today is - if you want to use a normal speaker >1W use a stronger Amp, in my case I am going to try TEA2025. While LM386 output power was between 250 - 1000mW (depends on which model you're using), the TEA2025 can give out 1.5W on 6V and 4.7W!!! on 9V (for 8Ohm speaker). I'll post some resultes after I get it, tomorrow :)
