Dear,

i think there is a doc issue on

https://www.hifiberry.com/docs/data-sheets/datasheet-dac-adc-pro/

when you write " Pin 1 is on the left bottom corner." regarding your image. it is not clear at all. 

where is VnL1, is it the 150ohm input or 0 ohm ?

and where are VIN1P, VIN1M pins for my balanced microphone? 

could you please give the answer regarding the connector (the jack) at the bottom?

please i cannot connect my microphone correctly.

regards

  As written, pin one is the pin in the bottom left corner according to the picture. 
  
  What do you mean by 150 Ohm and 0 Ohm?

  This is not possible. According to your schéma pin one is R1. Letf bottom regarding your picture is L1 or L2.. i measured résistances between your pins and thé input connector. Left up and right down have 0 ohm with connector. Left down and right up about 150 ohms.
