Paul F Posted August 23, 2018 Report Share Posted August 23, 2018 At a recent shoot, two brands of hypercardioid microphones became susceptible to RF interference. But my T-powered Sennheiser MKH-415 was not and it saved the situation. I did some reading and found anecdotal information that some people believe T-powered microphones are less susceptible to RF interference. My experience supports that opinion. That made me think I might want to add a T-powered hypercardioid to my collection. Is there such a thing as a T-powered hypercardioid? Does anyone have any comments about T-power and RF interference?

Philip Perkins Posted August 23, 2018 Report Share Posted August 23, 2018 My experience tells me that the thing that saved you was the design of the 416 vs other condenser shotguns, and the fact that it was T powered was not really a factor. I've had several situations over many years going back to when all my mics were T powered where the 416 (and 816) did not fall victim to local RF issues the way my other mics did. There are most certainly T powered hypercards around, although they aren't sold new any more. You can look for unconverted T powered Schoeps CMC head amps to add your choice of capsule to, you have your T powered 416, and if you look long enough you might find some older T power Sennheisers like 405 etc.. In my opinion the takeaway here is to keep the 416 (T or p48) standing by for those RF "moments". Quote Link to comment Share on other sites More sharing options...
jon_tatooles Posted August 23, 2018 Report Share Posted August 23, 2018 Our experience over the years supports Phil's. And from the mixer/input side, T powering can introduce other complexities, specifically if cables are suspect or the microphone input does not offer T and a 48V-to-T adapter is required. Phantom is a better electrical protocol all around. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted August 24, 2018 Report Share Posted August 24, 2018 Agree with Philip & Jon. You found out why it's always a good idea to have a 416 in your kit. Note that Pete Verrando will convert it to P48 for a very reasonable price. Quote Link to comment Share on other sites More sharing options...
Paul F Posted August 24, 2018 Author Report Share Posted August 24, 2018 Ok, good to know that. That wasn't a typo in my post. I have an old 415, not a 416. I am migrating from the Sound Devices 422 to a Zoom F8, so I will miss the switchable T power and have to dust off the T-power adapter that I got with the Sennheiser. At least there is plenty of room in the bag for it with the little F8. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted August 24, 2018 Report Share Posted August 24, 2018 http://www.416tupgrade.com/416Tupgrade.com.html Your 415 may well be upgrade-able by Pete if it isn't from too early in the run. Worth asking--send him your mic's SN. For me it was way great to lose the p48-to-T adapter barrel. Quote Link to comment Share on other sites More sharing options...
Scott Smith Posted August 24, 2018 Report Share Posted August 24, 2018 And of you’re looking for a hypercardiod version, the MKH 435 is a very nice mic. Was unfortunately only made in a T power version, but Pete might be able to convert it. -Scott Quote Link to comment Share on other sites More sharing options...
Paul F Posted August 24, 2018 Author Report Share Posted August 24, 2018 (edited) Thank you for the tips on the upgrade and the MKH 435. I emailed Pete. Unfortunately, I have a very old 415 with a Tuchel connector (Pete identified the connector name for me), that is not modifiable.

Philip Perkins Posted August 24, 2018 Report Share Posted August 24, 2018 Once you are in p48 world there are lots of hyper choices. Quote Link to comment Share on other sites More sharing options...
Ontariosound Posted September 8, 2018 Report Share Posted September 8, 2018 Don't forget the thick brass tube that the older MKH's had surrounding their circuitry. Quite the RF barrier. I own an MKH 435 as well, sweet little mic. Looks as good as it sounds. Quote Link to comment Share on other sites More sharing options...
