stefanosound Posted December 25, 2012 Report Share Posted December 25, 2012 my Senny 50 is getting a lot of interference, anyone with the same trouble? Quote Link to comment Share on other sites More sharing options...
Todd Weaver Posted December 25, 2012 Report Share Posted December 25, 2012 I assume you are talking about the MKH50. Is it hard wired with XLR cable or is it wireless? I've two of those and two of the 8000 series and I've never picked up any interference on any of them even under very active RF environments.. My Schoeps mics are a different story.

fieldmixer Posted December 25, 2012 Report Share Posted December 25, 2012 I've had interference in my mkh50. Serious interference. But at the time i was high up in a building just a few blocks from the largest antenna in Toronto. Nothing I could do but change out to my 416. Where were you when the interference occurred?

Eric Toline Posted December 25, 2012 Report Share Posted December 25, 2012 Depending on the age of your 50 you could have one that doesn't have the RF shielding in the new versions. If the 50's in question are 15 years old or less then it has the RF shielding. Sennheiser updated mine in 1999. Eric Quote Link to comment Share on other sites More sharing options...
RPSharman Posted December 25, 2012 Report Share Posted December 25, 2012 The 50s built with gold XLR pins are equipped with a newer chassis which is better at handling RF interference. Sennheiser offered a modification to older 50s which improved them but was not as good as the new chassis. It was a "shield" of some sort. I had this done to two mics, but still encountered interference occasionally. I had the whole chassis replaced on both mics and VERY rarely I'll get a little swishy sound. I swap to another 50 and it's gone. In a truly abusive RF environment, you just have to pull out the 416. Don't leave home without it.

stefanosound Posted December 25, 2012 Author Report Share Posted December 25, 2012 thanks Gents, may be is old version the XLR is silver. I got it second hand. Today I swapped with oktava,, last day with 416. Quote Link to comment Share on other sites More sharing options...
Max Hirtenstein Posted December 25, 2012 Report Share Posted December 25, 2012 interesting, i always thought the 416 and 50 were built the same in regards to RF. can anyone elaborate a little more? i just picked up an RF choke that clamps onto the mic cable, you can try that. perhaps it's the cable picking up some noise.

ChrisH Posted December 25, 2012 Report Share Posted December 25, 2012 Get the mic modded. I am currently in the process of rf proofing all my cables. I am changing all major signal path XLR connectors to EMC Connectors, I am also tying the shield to the shell in every connector and using starquad for anything less than 50 ft(boom poles and cart interconnects). This in turn with proper frequency coordination should give me a very RF rugged bag. My only snag so far right angle EMC connections for the top of the boom pole.

Chase Yeremian Posted December 25, 2012 Report Share Posted December 25, 2012 I have also had terrible interference with my MKH50, it was just down the hill from the Antennas on MT wilson, so I am chalking it up to that, My mkh60 also had issues, but the 416 was fine. Mine has gold XLR contacts so I assume it is current with RF shielding (got it second hand as well) but I have heard the color of the XLR pins does not guarantee if it has the current RF shielding or not.

Michael Wynne Posted December 26, 2012 Report Share Posted December 26, 2012 Also experience the occasional interference with my mkh50, It's relatively new with the gold connectors and I keep thinking I may send it back, but I think they are more sensitive to RF interference then other short shotguns. It's still my favorite sounding mic on a boom but I don't leave home without the 416 back up for this very reason. Quote Link to comment Share on other sites More sharing options...
Marc Wielage Posted December 26, 2012 Report Share Posted December 26, 2012 I've never run into interference with any of my Sennheisers, but I think all of them do have the gold-pin XLRs. Honestly haven't checked the 416 or the 816, though, since I normally reach for the 40, the 50, or the 60 (depending on what we're dealing with).

studiomprd Posted December 26, 2012 Report Share Posted December 26, 2012 " i always thought the 416 and 50 were built the same in regards to RF. can anyone elaborate a little more? " way incorrect! the MKH-60 was to be the next 416, which was to go away, much as the 816 finally did. different, newer technology in that whole series, and also built to be quieter, and lighter. (original MKH-60's and 70's were lighter than the newer, modded ones, as additional metal (and its weight) were required to resist interference.

Ray Collins Posted December 27, 2012 Report Share Posted December 27, 2012 I believe these mics could have two RF coils inside just like the 416 you could try peaking the coils with a non metallic screwdriver. Could be components have aged and changed value? Quote Link to comment Share on other sites More sharing options...
Jason A Posted December 27, 2012 Report Share Posted December 27, 2012 I occasionally get interference from lighting cabling on my 8050/8060. It's happened a couple times in the last year. Both times there was a dimmer in the chain and the lights looked a little worse for wear. My CS3-E wasn't affected. Quote Link to comment Share on other sites More sharing options...
