I'd like to make an experimental audio amplifier which have a condenser mic input, line input and export to an 8 Ohm speaker.
Although the actual output is unknown, I assumed that condenser microphones are approximately 10 mVpp,
line is assumed to be 100 times greater than the microphone.
Also I used dual power supply +-10V.
In result, the output Watt was too small and I think it wouldn't make any sound.
What is the problem? (Sorry for poor English.)
Please help.
