Zoom H4n Firmware Update Gives XLR Inputs Independent Audio Levels

Zoom has just announced a firmware update to its H4n Handy Recorder that enables independent level controls for its XLR inputs.  With the new firmware, you can capture your boom and lav mics at different levels and then the stereo WAV file can be split into two mono files in post production.

You can download the firmware version 1.70 update from Zoom’s website.

    So, I realize this post is super old, but hoping someone can help me out anyway. I was using a zoom that apparently wasn’t updated with this new firmware and can’t currently split my inputs. Is there any post production solution to this (i.e, FCP plugin of sorts)? Any Help is much appreciated!
