I did turn Soft Voice setting down to minimum and although that reduce the volume level for soft sounds, the static noise remains just the same, so I know it’s not due to soft sound setting.
This static/noisy mic in Full Directional is not really a problem I need to solve, because I never have any desire to use Full Directional in any one of my programs anyway. It was just a curiosity more than anything as to why there’s noise in that mode in the first place.
