Microphone Preamplifier Part 2

Hello Project Ryu fans,

About a month ago i reversed engineered a mic preamp module from an old console. If you don’t remember please refer to the article here. After i rebuilt the modules with newer components i decided to build a nice 2 channel preamp with them.

Below you can see the circuit for the unit. M1 and M2 are the modules presented in part 1.

Dual Channel Mic Preamp

As you can see it splits a 12V rail into +/-5V duble rails. I did this because i wanted to make it more mobile so i can power it from a big battery.

Below you can see my example of chassis.

This preamp doesn’t have a phantom power although you could easily add a +12V phantom power. In this regard it is best suited for dynamic microphones.

Thank you for visiting.
