Yours is an early sample as it has the NRDC engraving. but it has a slight mains hum A bad grounding in a connection cable, a ground loop? Inside the decoder just dry electrolytic caps in the power supply. Eero ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound

Re: [Sursound] Binaural Microphone options
I've had a couple of Len's DPA4060's since 2000. They are first class mics. Used them attached to my glasses just above my ears and they gave the most startling realism when played back on my Senny HD25 cans. I've had people jump and turn quickly when listening to recordings of motorbikes going up large rocks made with those DPA's. I think I figured out why people jumped and turned - they were standing in the paddock of a world championship event and knowing there were no bikes in front of them they instinctively thought the bikes were behind them. I was practically alongside the bikes when they were going up the huge rocks so it was scary for the listener to believe (even if only for an instant) that a bike was doing something like that so close to them. Those DPA's also give excellent quality on music but you may need a pad before your mic inputs if you are at a very heavily amplified venue. I bought the switchable bass cut version but never have used it as the bass cut starts too high for my taste. Oh and they're very susceptible to wind noise, virtually unusable outdoors even on a day with no apparent wind. I never used them without the little foam balls - a baby dead cat on top of them would have been pretty much perfect. Very easy to lose the foam balls off them - ended up hitting up a dentist for some miniature rubber bands to hold the foam balls on to the capsule.

Re: [Sursound] Binaural Microphone options
Rycote now make these - not cheap, but incredibly effective: I now have a pair of ex-theatre DPA4061s taped to the outside of a window of our flat as we get visited quite often by a wonderfully vocal blackbird who sits on the railing and marks out his territory by singing lustily to the surrounding rivals. The recording I've linked to here is an example: the background noise is actually a very strong wind blowing through the leaves of a tall tree in the across the way, so you should have some idea of how blowy it was. Not a trace of wind blast on the DPAs with the Rycote Mini-Windjammers fitted, even with the big gust near the end of the file. http://snd.sc/lbaFbi Regards, John On 19 May 2011, at 20:04, Bill de Garis wrote: A baby dead cat on top of them would have been pretty much perfect. ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
