claus Posted April 10, 2018 Report Share Posted April 10, 2018 Hi Group, I'm having issues with my Schoeps CCM41 - Cinela OSIX - Lectro HMa setup. It produces an unusable hiss. Already tried disconnecting ground from shell - no difference. Placing a short XLR cable between OSIX and HMa cures the problem, as well as using a Lemo-XLR cable from CCM41 to HMa directly. The HMa works fine with my CMIT - Rycote WSK4 setup. Has anyone encountered this problem before? Thanks and best regards, claus Quote Link to comment Share on other sites More sharing options...
cineli Posted April 10, 2018 Report Share Posted April 10, 2018 Dear Claus, your issues are now well known. The CCM is known to be RF sensitive under certain conditions. In accordance with Schoeps (with their design) we now provide our Minix suspensions (OSIX CCM doesn't exist anymore) with an RF filter which works well with the Lectro and other TXs. If you feel to do it "at home", we can send you the choke that you'll have to solder in the XLR. Please let me know ! P.Chenevez Quote Link to comment Share on other sites More sharing options...
claus Posted April 10, 2018 Author Report Share Posted April 10, 2018 That's what I like so much about cinela. Fantastic products and fantastic customer support! Thank you Philippe Quote Link to comment Share on other sites More sharing options...
soundpod Posted April 11, 2018 Report Share Posted April 11, 2018 Hi cineli, It would be great if you shared what your fix is, if possible? I have a similar problem with HMa and 8060, not in one of your mounts, maybe your fix could help me? Kind Regards, nick Quote Link to comment Share on other sites More sharing options...
Derek H Posted April 11, 2018 Report Share Posted April 11, 2018 Try a Neutrik EMC XLR connector Quote Link to comment Share on other sites More sharing options...
Matthias Richter Posted April 19, 2018 Report Share Posted April 19, 2018 I have installed that little choke in my CCM-Osix and can confirm that now the hiss is gone (using Zaxcom ZMT48V)! Small and effective solution. Great customer support indeed! Thanks Philippe! btw: was using a Neutrik EMC already. No help. Now it´s both.

claus Posted July 15, 2018 Author Report Share Posted July 15, 2018 Happy to report back, that the RF choke cured my setup and I can use my CCM41 with an HMa directly on the Cinela Osix now- yay!! Thank you again Philippe / Cinela. Quote Link to comment Share on other sites More sharing options...
r.paterson Posted July 15, 2018 Report Share Posted July 15, 2018 I am assuming the choke passes 48v?..thanks Richard 51 minutes ago, claus said: Happy to report back, that the RF choke cured my setup and I can use my CCM41 with an HMa directly on the Cinela Osix now- yay!!

joinwooHK Posted August 30, 2018 Report Share Posted August 30, 2018 can anyone show how to do it in XLR ? i solder the chokes on XLR female , no luck at all ,still hissssss Quote Link to comment Share on other sites More sharing options...
joinwooHK Posted August 30, 2018 Report Share Posted August 30, 2018 I have contacted P.Chenevez of Cinela , And he teaches me about some useful stuffs about this. i got 2 Instrument mics ,schertler DYN Gp48 and all cp411pp which have such RF hiss. But in my case , RF noise is because the mic is RF sensitive rather than in cable ,So any inline solution would be pretty useless on that . Just for others information ,Cheers.
