Similar to the MS microphone, the side microphone level (side mic level) can be adjusted to adjust the stereo width freely.
By setting it to "RAW" mode, you can also adjust the stereo width after recording. (*)
You can target certain sounds with the shotgun microphone, and mix the ambient sounds you pick up from the side microphone as needed. (*・"Q8" is not compatible with RAW" mode recording. The stereo width cannot be adjusted after recording.
