I have a yamaha mic, that needs 5 to 10 volts to work, from my sax player, and he wants a preamp. Any ideas...something simple, just to get into the mixer. Thanks!

I used it for microphones, pickups, etc...
Take a look at www.ti.com and ask for some INA217 samples, it's a hi tech mic preamp and can handle all mics type and power supply.

Thanks!!. Does anybody know working impedances of active mics?
