Difference between models
Could someone explain a little bit about how the 9.1 and 9.2 differ? I read somewhere there's a difference in sound levels? Are there perhaps any other sensor or hardware changes, or support for certain software features? I'm also curious how the different models of 9.2 differ between each other (9.2-4ANM, 4STN..)
I tried to find this information online, but after a long time search I didn't find much in the spec sheets or elsewhere.
