our main requirements is a, suitable microphone solution for our board room at Kolkata. 

The board room measures approximately 10 meters in length and 2.5 meters in width. 

We are using Sony 75X82L led TV (android version 10) for display and Logitech C920 HD pro webcam for VC through zoom, team or meets. 

The issue we are having is that this setup cannot detect the sound properly of a member who is more than 7 meters away.  

Considering this scenario, please share a suitable solution.
