[Elecraft] Heil Proset Ic with K2

[Soaring Eagles]

One more quick question:

I've got the Heil ProSet-Ic with the Icom (blue) adapter from Heil. 
However, I'm not sure if I need to connect the K2 mic connector pin 2 to 
the 5V line. In other words, I'm still confused whether this 
microphone/headset has the preamp in the mike or not.

Thanks a lot for your help. Otherwise, I think that's the last question I 
should have about the KSB2 and the K60XV is ready to put in, but I think 
I've got that covered! #5757 is getting nearly fully populated!
