In the attached circuit how can I increase the sensitivity of my mic.
from that reference I can only hear voice if I place my mouth too close.
Any smart suggestion will be appreciated.
Also,anyone can help me to my mic pre amp. Please refer to attached file. I also measure that the output of my preamp DC level is almost same as my VCC. While dc level in the input is half.
Thank you.
