Joe,

I've never studied the schematic or signal flow in the regard, but I 
often study the screen of my P3, which DOES show reduction of noise when 
the wider NB is active. 2-4 dB is typical for the types of noise for 
which it is effective.

I appreciate the alert to the existence of the P3 NB. I last updated 
firmware about six months ago, and it was not in that version. It does, 
indeed, work pretty well.
