Op-Amps work by measuring the difference between two input signals and outputing a signal which is proportional to that difference.

Wikipedia has a veritable goldmine of information on Op-Amps and how they work. In our project today, we will be amplifying the ouput signal of an electret microphone, these little silver cans are found everywhere; the one that I used in this project I took from an old house phone that mysteriously stopped working and nearly got thrown out! This pre-amp can turn a whisper into a loud, clear signal and is also very useful for listening through walls to quiet conversations.

If you look at the schematic below, created with eagle it really is a very simple project. Optional but recommended 9v Battery clip 3.

You can solder the parts directly to each other or use a piece of perf board. The microphone is the one critical part, and these are polarity dependant, so be sure check which is the ground connection it will be the one pad which connects to the side of the can.

The headphone jack is stereo so solder the output to both of the lines Right and Left , the odd one out will be the ground connection. Use wires to connect the microphone to the board. I assembled my Op-Amp on a small piece of perf board and then placed it into a small black project box.

I drilled small holes for the microphone, battery clip cable and headphone socket. I used hot glue to secure each of these in place in the box. Okay, so I hope you enjoyed my first blog post if anybody read it and found it interesting and informative, Ihope to be posting more very soon. Leave a comment.

These are some of the images that we found within the public domain for your "Ssl Mic Diy" keyword. From the equations there, the voltages on the two outputs are. In case of an electret microphone, the amplifier must have a gain that increases with frequency to compensate for the low sensitivity of the microphone for high frequencies. For preamp designs, I've always had good success with the circuits in the back pages of RCA tube manuals. Behringer is proud to incorporate a Midas designed mic preamp for the ultimate in high-quality audio reproduction in both live and studio environments. They are typically used to amplify signals from analog sensors such as. The circuit is exactly same as shown in the LM datasheet from Texas Instruments.
