Preamp/amp for tiny electret condenser mic

GoldMember · Oct 28, 2024

Hi. I'm looking for advice to find a simple test rig for these tiny 3 wire condenser mics. I have some of these mics and would like to connect them to something to see if they work or are dead.

For example, I'm thinking a mic amp like this. https://www.amazon.com/gp/product/B0BKF4BWGG/ref=ox_sc_act_title_1?smid=A3BKS5ISMXVHBW&psc=1

I'm not sure if this particular one will work with a 3 wire mic. I've written to the seller but haven't heard back.

Or maybe something cheap like this that I can plug into a small amp/headphones. But this one and all the others I've found are for 2 wire condensers. I'd need one that will work with a 3 wire mic.

Any thoughts would be much appreciated!
