    I'm Nelly GOURVES , I work for the CINELA company since nearly two years now.
    I used to be a sound mixer , i was also one of the fouding members of a sound equipments (for film, video and TV production) rental company that i left to join the CINELA company .

  1. The Kelly foam has to have the right fit (egg shape) so it's effectively not so easy to pack it in a small volume. The best is to fill it with anything "soft", like the fur, or even the Piano/Pianissimo itself, but we also found another way: It's possible to "roll" it in a certain way (picture) and keep it in shape with two elastic straps around. Maybe a new way to sell it ?
  2. On our side, we can simply make the reference "E-OSIX-AT4053B" and you should be happy with it. We can make the right fit for it (21mm, 127g). Philippe from Cinela.
  3. +18dB/oct @80Hz, analog (NOT digital), as early as possible on the audio chain...is just fine !
  4. Great shot ! I cannot resist to show you one of my first attempts in 1997. I'm sure you'll succeed in that risky way of the "extreme low frequency" isolation. P.Chenevez
  5. Dear users, a quick word to inform you about our new website (dead since 5 years) ! www.cinela.fr Not totally updated, with certainly many mistakes...but already filled with plenty of useful informations !
  6. Interesting topic ! On my opinion, I can say that if you request a significant isolation as low as 10Hz, I wish you a good luck. The suspension has to have a resonance as low as very few Hertz...and that concerns all microphones directions, knowing that you may have even more flexibility (unexpected) in other vibration modes. A nightmare for handling. To be honest, if you limit your wish at (about) 15 Hz, for a stand use, that seems doable. Anyway, the real challenge is wind protection. To keep a good acoustic transparency for the lowest frequencies (down to 20 Hz...or lower ?) seems very unrealistic with cardioids (or so) inside a "classic" windshield size (like 20 - 40cm main dimension). Such windshields (our Piano/Pianissimo/Albert ranges, or any other Brand) will definitely filter all low and very low frequencies (pressure chamber effect). If you were ready to make a DIY "large size" unit (like a tent or so), you could effectively be able to capture the lowest frequencies nicely, and I would be pleased to help you with some advice (structure or covers) ! But that's only my point of view... P.Chenevez
  7. So we made plenty of measurements (transparency and wind efficiency) and here is the simplest picture (wind test) that shows the difference between a KMR81i in Pianissimo or Piano. Lateral wind. 6 meters per second (common situation). The graph shows the noise level depending on frequency. - With the "fabric only", there is not more than 2 or 3dB difference between 80Hz and 300Hz (Piano is better). - With the fur installed, there is no significant difference between Piano and Pianissimo. Small peaks are only "artefacts" (motor noise). To appreciate these results, one has to focus between 60 and 500 Hz. Below 60Hz, everything will be filtered in post (or even in location), and above 500Hz, the level is really low. In conclusion, with the KMR8i, the difference between Piano and Pianissimo is not that much ! It's even equivalent if the fur is installed. Then, you choose !
  8. Very good question ! We'll make a measurement tomorrow (Wind efficiency comparison between KMR81 in Piano and Pianissimo) and we'll display the result here !
  9. Headphones and silence, that's all you need to make your own opinion on some units. Youtube https://youtu.be/3Em4RvvTfOs Facebook https://www.facebook.com/Cinela-1471314373154513
  10. Just in case you can contact us ! contact@cinela.fr We have such a windshield ("Albert" range) for two 4011C
  11. Yes, this "rubber thing" is what we call the "bellows". With time and dust, there can be some friction noise between hard parts (lateral screw or main axis) and the flexible material of the bellows. Please use baby powder (talc) on surfaces in contact ! An ear stick is a good tool for that. In any case you have some unexpected noise like this one, feel free to write an email at contact@cinela.fr !
  12. Let me confirm the major difference between the C preamp and the B one: No filter at all on the C. The B integrates a hidden 3rd order filter (+18dB/oct) at 50Hz, not talking about the ring one. Basically, the 4017C is a rumble generator. And if that was not enough, a suspension is a rumble amplifier. To be a little simplistic, I have to say that a bad suspension has its resonance in the audible range...and a good one frankly below 20Hz (with HIGH resonance factor). No problem at all if your recorder/mixer integrates a high slope filter (+18 or +24dB/oct) in the input first stage, but take care to digital filters or too smooth ones (+6 or +12dB/oct). Don't be surprised if the limiter reacts ! As a conclusion, the right tool is NOT simply a good microphone and a good suspension, it's a combination between those...and the right filtering. Tell me if I'm wrong and I'll change my life.
  13. Maybe this trick is a line of the famous "Pin 1 problem" defined by the AES. Thank you "rich" for this reminder. @Ivica, in case it doesn't work, please let me know in PM or directly on this thread. We may have another option... Philippe@cinela
  14. Effectively, by principle, due to external isolators, COSI has a fixed cover.
  15. The XS version is not sooo different than the S one. It's only 17 mm shorter. It has been created to offer the shortest fit to the CMC1, but is also perfect for the 4018C (with the 19mm holder). The S version may accept a bit more microphones (with proper holders), but if you only have the 4018C, the XS will be perfect ! Never forget that the more "dead air" you'll have in front (and around) the membrane, the more efficiency you'll get !
