Hi Mitch & Ray--
The noise performance would still be determined by the input noise in
the HS700's mic input. A line -> mic adapter readies the line level
signal by attenuating it about -40dB.

Opps, I forgot to mention that if the HS700's mic input only has
auto-gain, the recordings will "pump" and this makes nature
soundscapes sound pretty bad.  If it turns out the HS700's mic input
is noisy or it only has auto-gain, looks like you're stuck with using
another sound recorder.

If the HS700 does have _manual_ audio gain, one way to test/compare
recorder input noise is to make comparison sound recording in the
same, quiet location with these two record chains:

AT4022's -> RollsPB22 -> Mic Input M10 (max or near max gain)
vs
AT4022's -> RollsPB22 -> Mic Input HS700's (max or near max gain)
