Condenser Microphone Amplifier Circuit Diagram. The two transistor mic amplifier circuit is isolated into three sections. Finally we need one more component a bypass capacitor between the emitter terminal and the ground thus c e.
Finally we need one more component a bypass capacitor between the emitter terminal and the ground thus c e. The 10kω resistor attached to the transistor through its collector allows the triggering of the ac component while the 100kω resistor acts as a collector coupling resistor. If you want to learn about microphone or little use.

The audio amplifier circuit needs 6 24v as per amplifier specification. The c1 in this circuit is the same capacitor c described in the electret microphone circuit above and its role is to cut off the dc offset of the input signal such that we work out only the ac component of the input signal. Cond mic need often arises for a sensitive sound pick up device whether it is to be used as a simple microphone or a more exotic device as a sound operated alarm a bugging device or a sound operated flash for stop action photography the list is quite unending. You can connect condenser mic with an amplifier circuit as given below diagram.
