It is a phono pre-amplifier.

I will try tomorrow.

Alsamixer shows similar picture here without differntiation between
Microphones.

The Aux input has two channels with sliders, so I will try this way. I

Will need a little metal work and soldering.

No Pulse Audio.

Thank you for your tips and your help. I will report about success.
