How To Connect Microphone with Any Amplifier

Homemade MIC Amplifier Loudspeaker connection circuit

You can connect condenser MIC with any amplifier circuit as given below diagram . This circuit will work very well with any type of Audio amplifier. Use only 5-6v for condenser MIC for best result. Audio amplifier circuit need 6-24v as per amplifier specification. 

Connect the positive terminal of mic with 47 k resistor in series with positive supply and negative terminal of mic is directly connected to negative supply or ground. And enjoy this easy homemade MIC Loudspeaker. 

This Circuit works with any type of amplifier circuit. 

If you have no any audio amplifier then you can make an small amplifier very easily with LM386 ic. This is very popular amplifier ic and available on any electronic part store.




Here is a circuit diagram of popular small power amplifier using LM386. This is best amplifier for small power. This works good with 6v DC. You can make this amplifier at home very easily.
