Hi
I have built a vu meter with the LM3915 IC and i want to amplify my audio signal because its to low from my mp3 which is 300mV.
To how much should i amplify the voltage and why?
Is lm741 a good amplifier to use?
Is there any difference between using ±12v or 0v and 24v to supply the lm741 amplifier?
Thanks,
