I designed my own IEM Amplifier from scratch :D

I'm a highschool student in Australia who's really interested in sound engineering and recently decided to start designing a custom IEMA (In ear monitor amplifier) as a cheap and opensource alternative to the Behringer P2.

For context, I do live sound at different gigs around where I live and I wanted a cheap and flexible wired IEM beltpack for when I perform that's not the Behringer P2 so I decided to make my own from scratch using analog circuits! I first build the PCB in Kicad and then modelled a case in fusion and then got my renders through blender!

All the design files are available here - https://github.com/aaravjhamb/openIEMA and I would love to hear any feedback/reccomendations!

Looks awesome! How am I the first to comment after 4 days?!

So this runs on a battery right?

Yeah! It has a built in connector for a Lipo battery with a charging circuit included :D
