I am trying to record those for my short film, as long as all the quiet sounds left. However footsteps are tough, because they are quiet to the point where the recorder is not picking them up. I have the FR2LE and was recording with the AT4053b mic, and I also have the NTG-3. I turned up the trim and gain all the way, and they are still barely picking up where the levels are reaching at least 12. What am I doing wrong?
