[AudioI] Pre-Amplifier for stereo condenser microphones

[Christoph Völker]

Hello community,

I would like to run Binaural Microphones/Earphones with a raspberry pi:

These are stereo condenser microphones built into earphones. The mics 
need to be amplified by 2V to 10V.

How would you do this? Can I somehow attach a 9-volt battery to the 
stereo soundcard (http://www.audioinjector.net/rpi-hat)?

Many greetings and thanks,
Christoph
