Guys, I can't afford a professional sound guy to take care of this for me while I focus on directing. But, I've decided to record my own sound, which lead me to buy a RODE NTG2 and a ZOOM H4n Pro. I've noticed that the sound isn't bad, but the frequency is far too low. Is there anything a can do to get the best out of this set up? I usually make tiny little horror films, such as Lights Out or Tuck Me In.
