This microphone has a self-noise that sounds like a calm ocean, even though it was easy to extract (using Noise Reduction effect in Audacity). I am recommending turning the MIC. LOW CUT filter on (for all "proximities") for a few different reasons, but it did not remove the "ocean" sound. What the MIC. LOW CUT did improve was (at this "CLOSE" proximity) it removed the excess lows/bass frequencies that occur due to the "proximity effect" (being too close to a microphone creates more bass). In this case of this microphone, the result is that it sounds more "REAL" and natural, so I'm keeping the MIC. LOW CUT on (it also helps reduce handling noise, as the shock mount on this mic is not too good). Like the older version of this mic, it is also interesting is that when using this with the Zoom F2 32-bit float recorder, the audio sounds cleaner and more "REAL" without turning the +10 MIC. BOOST on (I had to turn it on for the other non-32-bit-float recorders, to get close to a proper level, but with the 32-bit float recorder, boosting a low level during editing sounds really clean! The same was true with the Takstar SGC-598.) This microphone is also louder then the older version (the Takstar SGC-598) at the +10 setting. Likewise, the +10 boost on this mic is not a very good quality amplifier, so it sounds more fake when it's on, as well as amplifying that "ocean" sounding self-noise of the microphone. So, do NOT use the +10 boost when using this with the Zoom F2 at this CLOSE proximity.
