Noise can be added to a recording even by the quietest mic and preamp
if the subject of the recording is very quiet, and the gain is turned
up enough.   The sound of silence, unfortunately, is the self-noise of
your equipment.

Raimund Specht's tests show the preamp in the FR2LE to be very quiet,
even at full gain.  See the results here:

In this case, I'd ease up on the trim setting.  My quick look at a
FR2LE showed that it's easy to overdo the trim.  Then back off the
gain to 90% of maximum. That should reduce machine-generated noise
considerably.
