cmassey Posted August 20, 2014 Report Share Posted August 20, 2014 Not a regular user of the COS 11D, but last week was loaned one from the A sound guy so our stuff would be a closer match. Mine had horrendous cable noise...just a light touch or rubbing a shirt...even mounted visible outside the tie. This was with SMQV transmitters. The other fellow says he gets that with some and not others. He gave me another and it was fine. Is this wiring...universal vs. servo-bias? is the inclusion or lack of a capacitor in the wiring? Shedding any light on this would be appreciated. He would like them all to work fine, and I might go out and get a couple if they work as they are supposed to. thanks gang.... cleve Quote Link to comment Share on other sites More sharing options...

Don't crush the cable but the shield should be firmly contacted. Best, Larry F Lectro Quote Link to comment Share on other sites More sharing options...
Jack Norflus Posted August 21, 2014 Report Share Posted August 21, 2014 If the cable is being pulled tough they will be some noise on thr cable. Make sure there is some slack. Quote Link to comment Share on other sites More sharing options...
Dennis Kersten Posted August 21, 2014 Report Share Posted August 21, 2014 A small and light knot just before the capsule helps a lot. Quote Link to comment Share on other sites More sharing options...
cmassey Posted August 21, 2014 Author Report Share Posted August 21, 2014 Ah, enlightenment for the uninformed. This is not a matter of the wiring making the mic too sensitive and creating noise down the cable, but just a COS 11 thing! Actually that previous thought is pretty far fetched...may order a couple of them today! Many thanks...cleve Quote Link to comment Share on other sites More sharing options...

old school Posted August 21, 2014 Report Share Posted August 21, 2014 I've never had your issue Cleve. I own many cos 11's and a few DPA's and Trams. They all seem to excel at different things in my experience. Can't have to many mics IMO. CrewC Quote Link to comment Share on other sites More sharing options...
cmassey Posted August 21, 2014 Author Report Share Posted August 21, 2014 Good to know it may have been a less than perfect fit of the grounding clamp. The other fellow and I talked and he is going to look at all of his and check the clamp. I'm a Sonotrim...B3...even Sony ECM 77(for certain settings) user! But Crew is right, you can never have too many mics. gracias... Quote Link to comment Share on other sites More sharing options...
