Introduction: Build a Dynamic Mic Pre-Amp

Hi Guys..!!
You're welcome to "Sam Technology Professionals"

This project is all about a Dynamic Mic preamp which has very good gain. And the sound of output will change the way of your broadcast or recording.
This is good for ribbon microphones as well. I tested a long ribbon microphone and it works well. One thing i mentioned everywhere is that it needs an ultra clean power supply that's what i say in video and i wrote about it on my BLOG.
If you don't know about creating power supplies or filtering the power supply then you can use 9v battery for it. Batteries supplies the clean DC. Well here i attached circuit diagrams. I design one as basic and in other i just added a 10K pot to control the output gain.

I also attached the video tutorial that is all about this pre-amp.

Components are very simple and are easily available in the market.

    can i amplify my electric guitar sound by directing the output to this circuit
    my guitar dosnt have an onboard pre amp, so i have to connect it to the amplifier all the time
    is there a way that i can use my speakers instead of using my amp by directly amplifying the output of guitar and then by the means of aux play it on my speakers

    Yes, you can use it as a pre-amp. You can plug your guitar on its input. Then its (pre-amp) output should be connected to your speakers (with built in amp) or amplifier, If it is an electric guitar. I hope that your guitar has a magnetic pickup. If it has peizo pickup then you need to try my high impedance pre-amp circuit that can be found here:

    Hi Friend..!! Actually here Dynamic
    means a "Dynamic Microphone" which is consist of a coil winded around a
    magnet and is attached to a diaphragm when we speak or sing the sound
    waves strikes on diaphragm and it vibrates the coil around magnet and
    the current produces. This is how they work. Best examples of these
    microphones are "Shure SM57, SM58, SM58 Beta" the most popular
    microphones. However condenser microphones are different so this design
    won't work for condenser microphone but may work for "Electrek Condenser
    Microphones" which is en-capsuled microphone usually found in
    computer's headphone.

    Thank you for asking. Have a great day..!!

    ah, i see, i thought it was something about how the signal was treated,

    thanks for the comprehensive reply!

    (PS: there are half a dozen reposts for some reason, you might want to remove them! :D)
