Name: Sony PCM D100 SN 100db Field Test by CliveUk
Duration: 1 min 50 s
Description: Field test of Sony PCM D100 - 1st section with S/n 100db feature off, 2nd section with S/n 100db feature on. Consecutive recordings using DIY 'Powys type' SASS stereo rig with 2x2 EM172 electret. LCF 150Hz no post processing. Site - wildflower meadow surrounded by woodland. Quite a lot of insect activity.

I thought the SN100 is used where clipping would be an issue, hence the reason you can't have the D100 Limiter on and the SN100 function at the same time, since both handles loud sounds differently to protect the recording.

Thanks for the comparison. I can't say that I can notice any difference. I've just tried two recordings on my Sony PCM-D100 with the S/N 100db feature on and off, and couldn't tell any difference on that either. So mine will just remain off in future.

Hello Clive! SN100 function is useless at average recording levels (like your file here). But it really works at very low recording levels. I also have Sony D100 and tested it a few minutes ago - it's working! Signal level was around -60db, not very useful for everyday life but maybe you'll get cleaner recording when you make it louder in post-processing. I'm quite impressed! Try it for yourself!)

Sony PCM D100 SN 100db Field Test

when?
recorded around 3pm 7 july 2016

where?
Kings Marshes, Orford Ness National Nature Reserve

how?
two Jez Riley French hydrophones, placed a bit more than a meter apart, a few centimetres under the surface algae, as shown in the thumbnail image.

left and right channels show clear difference in insect/animal sonic activity. i have panned them hard to left and right, but not completely, so there is a bit of overlap. further, i left the recordings in their original state, with no EQ adjustments whatsoever. you can hear water beetles, water boatmen and the sound of aquatic plants as they take energy from the light. (thank you JrF!) any further help with insect/animal identification would be greatly appreciated!

A comparison of SSM and SassLite, both using twin pairs of Primo EM172 capsules per channel.  Both units weigh the same.  One is commercially produced, the other is home-made.  Not much in it really.  The SSM image is more centred than the SASS which has a wider image.  Rigs are set up one metre apart, 6th September 2012, early morning near a dam in NSW, Australia.  Noisy Friarbirds are calling in the distance to the left and a pair if Australasian Little Grebe call occasionally near the centre.  Both rigs are running to Olympus LS10 recorders, levels set at Low 10, no low cut.  No filtering.
