Hi!
I am in dire need for a microphone amplifier schematic! I'd love something simple that I can piggyback onto some amplifiers.
I've got BB opa2134 and opa2227 lying around. The mic I'm interfacing is a Sony ECM-719. It is specified with a 1500Ohm impedance and a -47dBm output level. What is the simplest way to boost this to a level commparable to an audio line voltage?
Cheers,
Børge
