  1. Yes, i have got the cables from audio with the filter built into the plug. Works well with dpa 4017/4018 and ok with senn mkh 50. With Schoeps ccm lots of noise. Tried removing the connection XLRshell/ground in the Cinelas, but that didnt make any difference.
  2. Hi all, Its about Audio ltd A10 for wireless boom. I recently changed to this setup and got some trouble with rf/noise picked up by the mikes/cabling. Especially my ccm41's in cinela osix are unusable. Does someone have similar experience?
  3. Same here, after setting it to factory defaults. I didnt yet find out what routine causes the problem. Did u already inform SD about this?
  4. Hi Dalton, will get back to you if youre interested. The project likely spans for 2+ years, as alot of the targeted situations are seasonal. If you missed it this winter, you gotta wait 10 months. Some of the picture is already done, but mostly without sound ( long lenses, noise, etc). Yes, nature docs are fun to do, lots of improvising. In the last weeks we did some tests to bring micarrays on heliumballoons high up in the middle of big birdswarms. the outcome is promising, very interesting perspective.
  5. Hi Dalton, Thanks, very interesting! Do you have experience with mics/transducers of this brand?
  6. hi all, for a wildlife documentary, i am researching possibilities for longtime mic-installations in full out weather... as this sounds like quite a contradiction, i wonder if anyone of you has experience to share regarding this topic. the mics ( at least the capsules ) will be high up in trees, installed by crane, as are some endoscopic cameras. everything is cabled down to ground for signal, powering etc. once breeding season starts, we cant get close anymore. i am posting in the diy section, because i think the solutions from the shelf will not work here....
  7. wish list.... - a10 mini tx - the 24-bit-signal of a sonosax micpre/ad being wirelessly transmitted by a recording digital TX. All in a small, remote controllable package for boom-tip mount. And running on two or three AAs... todays wireless boom solutions sound very ok. but nothing like a good old cable, as advertised by some. there is room for improvement....
  8. if there was neverclip in the phantom version, it would be such a nobrainer for wireless boom work. maybe it is also without neverclip. so small and light. are these transmitters already out in the wild for real world feedback ?
  9. hi jez, it's not exactly recent. it ran on bbc4 some 10 years ago. try this channel. http://www.dailymotion.com/AlchemistsOfSound m
  10. not specifically related to fieldrecording, a bbc doc called "The Radiophonic Workshop" .
  11. guess its the same as bostik/prestik. its widly used here to stick mics ( amongst other... ) to almost any uneven surface. consists of polyisobutylene
  12. Hi Jesse just wrapped a 5 weeks shoot with the mini. cant comment on how well it is holding the timecode internally, i went the tentacle route (one always on my deva, one always on the mini). these boxes are perfect for the small alexa mini rigs and they hold timecode incredibly well ( less than 0.1 frames drift after a 12 hours day ...). as mentioned, the tc connector on the mini is placed less than ideally, i had to make a small profile, right angled lemo plug. all in all a breeze with this setup.
  13. To tape down stubby/short chest hair i found a tape called Mepitac. Its a very soft, broad silicone tape that wont pull any hair when beeing removed. it doesnt stick too well, but mostly well enough, except for talents with heavy perspiration. on long chest hair it doesnt work.

    sony m10

    i had a m10 and some old dpa4060 lying around and put together a small rig that i can take with me on travels. really surprised how nice that sounds. the m10 delivers about 3volts, enough to power the dpa´s. the preamps sound more than ok for such a little box. and it runs half a day on 2 AA´s. the mics are mounted on a hd25. i replaced the 3.5mm jack mic input on the recorder with a less fragile connector . if you rip out the internal mics, there is enough space to put in small connector ( hirose in this case ). you will need something with 4 pins, as the original input is activated by shorting 2 contacts by the sleeve of the jack. and two short sound snippets, made with this rig streetkitchen chiang mai.mp3 atmo chiang mai.mp3
  15. hi michael, i used diy lifepo4 batteries for the last 2 years exclusively, but with lesser capacities ( 20 ah ), put in small pelicases. weight reduction is stunning and they proofed to be at least as robust as sla's i did the first pack with just 4 plain cells in series, no protection board. i cannot recommend this at all, as the cells will absolutely die , especially when overdischarged. also, the cells voltage will drift over time, reducing the effectively usable capacity. so, some sort of balancing circuit is recommendable. the places selling those cells are usually carrying a variety of different protection circuit boards in their sortiment, also pcb's with integrated balancing circuits, which i use ( eg. http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=5175 ). generally, lifepos need a slightly higher end charge voltage than sla's. as chargers i use ctek car chargers with 14.7v end charge voltage, which are primarily laid out for leadacid, but will charge lifepos ok. never tried a designated lifepo charger as there was no need until now. i guess the powermax chargers will be ok, as they are also designed to charge sla's. they might not charge the battery to a full 100% , but they wont damage the cells due to a slightly low end charge voltage. the discharge curve of lifepos is very flat and voltage under load is quite stable. so, a topped off battery will start around 13.4v and then quickly settle around 12.8v , from where it drops towards 12v until nearly empty. the voltage drop in the end is very steep, so if voltage falls under 12v, the battery is basically flat. marco
