Hahaha, Rodolfo you made my day. It was anyway a hard week, so good that I
read your post :)

The mic is mono, so the input if I am not wrong is mono as well.
Check of course the specs of your board. On my one (pretty standard) it
says:

Interfaces
Audio: line-in          1
Audio: line-out         1
Front audio: microphone 1
Front audio: headphone  1

in linux language

$ amixer
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 11477 [18%] [on]
  Front Right: Playback 11477 [18%] [on]
Simple mixer control 'Capture',0
  Capabilities: cvolume cswitch cswitch-joined
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 65536
  Front Left: Capture 7353 [11%] [on]
  Front Right: Capture 7353 [11%] [on]

$ ls -1 /dev/snd/

controlC0

pcm____c is capture device (p is playback)

The mic has also different Ohms or perhaps better to say impedance, so I am
not sure if it would work, but you could try plugging those mics to the
line in, not the mic.

So line in, is the stereo one. I think if you plugin mic(s) without preamp,
because of the high Ohms, it would be very silent, but still worth a try.

You need a stereo jack to L-R like this one

This way you'll also know if it is true stereo, because if you unplug the
one mic, it would record only on the other channel. Of course you can see
this in audacity or even with arecord

However I am not sure what would be the purpose of all this, but you know
perhaps better
