High power class D Amp Build (5 channel, spectrum analyzer, pre&post-amp signal leveling)

e14 Contributor

Well I hope this is the right place to start this discussion. I don't know much about element 14.

 

Anyways, to the point.

     The goal here is to make a high power (ie 5000w) 5 channel class d amp with signal leveling before and after the amplification process as well as having a spectrum analyzer. To get even more in depth when I explain this lets say I want it to take an audio signal in, analyze and level that signal, amplify that signal, analyze and level that signal again, send that signal to a spectrum analyzer, and cross that signal over to 5 channels (high-fq-l/r, mid-fq-l/r, and then 1 low-fq) all while maintaining great efficiency and audio quality.

     I need help making the power supply, the eq and spectrum analyzer (thinking about Arduino), the amp it self, and the cross-overs (everything pretty much). And It has to be from scratch (as much as possible).

 

     If I can get a list of all the components I need to have knowledge about I think I can figure out how to make this project come together. That's basically what I'm asking of you. Can Someone get me a list of components to research such as MOSFETS, Microprocessors, etc...?

    Hi Buck, I would check out a book by Paul Scherz and Simon Monk called "Practical Electronics for Inventors ". Make sure you get the Third Edition as this edition is pretty clean of errata. This book takes you through the basics of electronics including MOSFETs and Arduino. While it will not give you the exact instruction for building what you have described in your amplifier project it will get you started in the right direction.
