OK,



I'm a novice at this and all my formal training is in biology, not
engineering or electronics.  I did take physics as an undergrad, but I thin=
k
my professor was Isaac Newton. ;-)



I have been making some frog recordings with a Sennheiser K6/ME66 shotgun
into a LS-11 recorder.  I recently purchased a 90 elbow microphone plug
extension for the recorder to stop me from bending plugs.



Recently a new problem has arisen.  When I import the recordings into
Audacity, I can't get the gain up high enough even though there is plenty o=
f
gain in the recording as far as I can tell.



Doing a little research on the internet, I saw a suggestion to split the
stereo track, invert one of the two resulting tracks, then recombine the tw=
o
tracks back into a new stereo track.   Surprisingly (to me) this works like
a charm.  I now have plenty of gain.



I have no idea what "inverting" the right channel does, or why this works,
and might not understand if you explained it to me.  But what can I do to
avoid having to do this?



If I record directly off the LS-11 built in mics, I have no such problem.



Any gentle input?
