Build and Review: DIY Dual Mic Preamp (ESP P-66)

when you said 'you only need 4 mics for drums' i started sweating, i can barely manage 16 tracks on my reel to reel lmfao

Da hora esse som que você gravou, parabéns... o capacitor explodindo foi um show a parte, kkkk. Um abraço

Maybe be a dumb comment but how do you connect the xlr jack to the circuit? I’m mainly confused on the hot/ cold wiring and where it goes and what is the point of it?

Just one Q: does it sound GREAT?

incredible video, love it. Great song as well,

Thank you for sharing this! This was an awesome watch!

I didn't expect the amazing ending!
Thank you for that!

I like how you specify “not successful”:)

Nice!
Gosto muito dos projetos ESP.
Muito honestos e sérios.
Parabéns pelos trabalhos eletrônicos e músicas.
The best regards

If the preamp works well with two 9v batteries, then +12/-12v psu should also do, right?

Twist cables which connect pin#2 and pin#3 from XLR sockets to PCB. Pots cables also. Would increase interference immunity.
It is better to choose insulated sleeve output sockets to avoid ground loops. Use single ground connection between chassis and circuit's ground.
Use deserve quality 1:1 signal transformer to get floating balanced output.
Sorry for my terrible language.

MUITO BOM

I really appreciate the video. I have only two things to add from my perspective. Motherboard stand offs are super cheap and you can usually just drill an appropriate hole and they will almost always cut their own threads. And I do plan on building this almost identical to what you have done here but with combo XLR output jacks instead of 1/4" just for versatility.

“Four preamps should be all you need to record live drums.”

Great build but most importantly GREAT cover at the end. Any chance that you upload the whole song? To my ears, your voice suits it better than the original.

I was planing to build this preamp for years :) great stuff diy perks also made it but portable version for field recording.. Also i have steinberg,it has great preamps color wise but lot of noise, it has 2068d jrc opamp i am planing to upgrade it with lm4562 bi texas instrument.. Can you make video of you upgrading yours? I have low knowlage of eletronics

I had to watch the magical smoke release three times. Normally I only get to see the results but not the process.

Best live 'magic smoke' capture I've seen in a while!

Is there a way to wire this up to have balanced outputs instead of unbalanced? Might’ve missed something, but I’d find a balanced output more useful in a more professional setup
