[Elecraft] Microphone Qusestion

[Bob McGraw - K4TAX]

While I don't have my new K3S radio yet, I did print the Owners Manual.  
It shows the MIC audio connection to be pin #1 as MIC audio, pin #7 as 
GRD, and pin #8 as GRD.  My question, are pins #7 & #8  the same or is 
one analog ground and one chassis. ground. If so, which is analog ground 
and which is chassis ground?   I'm making a mike cable XLR to 8 pin.
