My experience too-- side mics are often less sensitive. I use the
MP2's "HP" (M-S headphone mix) setting with relative volumes to test
mic location and the stereo imaging possibilties but then I shut it
off and proceed to saturate both channels as high as I can while I
record. More options if the stereo image is created in post. The RF
could be from numerous sources in the location you describe. If it
never goes away in that location. it could be something in the mic or
cables. Rob D.
