Looked at schematic for audio processor and u2a only has pin 1-4,however there is a 15k between pin 1 and 2 of u2a. The chip info in  my manual shows a dot to indicate pin 1. 

1>    8             > is dot.  Is this the right one? 

2      7 

3      6 

4      5

*I think R68, at 15k ohms, is holding the first mic amp gain down n the 
Corsair. 

If I recall correctly, I have in the past changed this resistor to* 
*around 220k-330k to bring the gain up.  The Paragon has a 470k in that 
position. 
In the Corsair, that resistor is between pins 6 and 7 of U2A
