I used A1 on my 861v8 both the label on the unit and that picture shows the top left one and in Mconfig it says IA04#01 A1. So I think I done everything right.

That microphone also has a USB XLR soundcard and that confirms that the microphone works I can see a meter move when I go into "Recording devices" in Sound settings in Windows.

This is all new to me so I don't know what could be wrong?

This is the MIC I'm using XTZ.
