Today let’s try to make a microphone. By using a condenser microphone preamplifier circuit. Why would we need said circuit? Because of its high sound sensitivity, easy to use, small, and cheap. For example, It can be connected directly to your power amplifier through the AUX channel. Then, you could hear your voice clearly from … Read more
The Hi Fi preamplifier circuit project to tune smooth bass-treble, with a very low distortion. Use low noise transistors Frequency response range 20Hz-20KHz […]
Want very high impedance preamplifier? We may have many circuits to do. But the FET Preamplifier circuit might be good choice. Because of small, easy, and cheap.
Want a high impedance preamplifier circuit? For a ceramic record player, etc. Make the emitter follower circuit has low noise causes sound concise.
Try medium Impedance Preamplifier circuit using only one transistor. Use a common emitter. Have a lot of circuits use this. try it and learn with fun.
