Hi!
I'm finishing my studies about Telecommunications Engineering this year and I have a few subjects about electronics and circuits and I wanted to do some real projects about it. As I'm starting taping I'm really curious about sound-related things. As I haven't had nor a battery box or a preamp yet I thought could be great to start my electric projects with something like that. Does anyone have preamp schematics? I want to use it with microphones ended in minijack.
Thank you so much

I shamelessly bump this topic asking for the same thing: some schematics of a decent preamp. There's some on the internet but they're whether too simple (for a mono input) or too complicated. I would like to build a simple. ChurchAudio-like stereo preamp.
Thanks in advance!

If you're both looking for an educational project, I might recommend starting simple with a CMOY headphone amp. It's not a perfect apples to apples comparison to microphone pre's, but will get you started down the right path.

Thanks for the suggestion, but I'm not following the educational path. I am proficient with the soldering iron and pretty knowledgable in electronics -if I might say so- , so I would like to build a mic preamp directly, without simple starts. I've done similar things before and they all are working after years of use, so I think I could get decent results building a preamp. It's just that I need a good schematic for it.

Gotcha... fire up SPICE and design your own circuit then! Kirk poitned out the fivefish stuff which I completely forgot about and there are all kinds of kits for home discrete and tube amplifiers, but you're not gonna find too many published circuits for small 2-channel preamps. Jensen's website might have a few good ones as will some op amp publications.

Kirkd pointed out Five Fish Audio kits an excellent choice.
A Less expensive alternative for a student budget is a kit from PAiA...

Great!!! Thanks for the answers everyone!

There is no circuits out there. The best way to start is looking at product data specs and sample circuits and start from there. Simple also invest in a bread board. Sprice is nice but reality is better. Some things that work in spice dont work in the real world.
bread board and some parts is where I started I also helps to have some really REALLY smart friends who can help you when you are lost.

Thanks for the tip Chris, your replies as well as the others are always welcome. I use to do all my projects on a protoboard before doing them in a real pcb and soldering. It's a great way to try ;D

The is a Yahoo "group" called "micbuilders". Lots of folks out there build circuits and also modify mic capsules.
A whole lot of fun/diversions over there.
