Homemade MIC Amplifier Loudspeaker connection circuit
how to connect condenser mic to amplifier
You can connect condenser MIC with an amplifier circuit as given below diagram. This circuit will work very well with any type of Audio amplifier. Use only 3-6v for condenser MIC for the best result. The audio amplifier circuit needs 6-24v as per amplifier specification.Â
Connect the positive terminal of the mic with 10 k resistor in series with the positive supply and the negative terminal of the mic is directly connected to negative supply or ground. The output terminal of this circuit is at the collector of the transistor through 0.1uf capacitor bc548 transistor. The ground of the Amplifier and the preamplifier circuit is directly connected. You can use this circuit for any Audio amplifier circuit like 6283, 386, 4440, etc And enjoy this easy homemade MIC Loudspeaker. I suggest using the only battery for mic preamplifier because if you use an adaptor then this produces more noise.
This Circuit works with any type of amplifier circuit.Â
If you have no audio amplifier then you can make a small amplifier very easily with LM386 ic. This is a very popular amplifier ic and available on any electronic part store.

An amplifier (amp for short) is commonly used in conjunction with musical instruments, such as electric guitars and keyboards, although it is possible to hook up other devices to the speaker, including a microphone. However, hooking up the microphone does require you to use an adapter as the signal coming from the microphone uses an XLR cable while the amp accepts 1/4-inch connections.
