Max and all,
Max, try putting your LS-10 on recording level 5 (REC LEVEL knob on
right hand side). Make sure the high sensitivity switch is on. Then
try to get as close as possible to the singing bird (or frog or
whatever), and preferably when it is not windy. On level 5 (with the
built-in mics), you should get a useable signal. If you don't, you
are not close enough to the bird. When you download the sound to
your computer and listen through good headphones, you will get a true
idea of what you have recorded. The LS-10 headphone outlet (VOLUME
knob on left hand side) is fairly weak so don't rely on this for
judging your recording quality.
Yesterday I soldered up a pair of WL183s and tried these with the
Olympus LS-10, but not yet in the field. The 183s give less noise
than the built in mics, and may be better when used with the LS-10
low cut switched ON. More on this when I have tested them in the field.
The photo of my home-made windscreen for the built-in mics is now
uploaded to the naturerecordists web page, look under the heading
PHOTOS.
