bendybones Posted October 7, 2012 Report Share Posted October 7, 2012 Hi All, I am wondering how the KM150 would fare as a boom mic. It would allow my Oktava Mk012 to retire from boom duties (aka handling noise duties). Has anyone used the KM150 for booming? I'd love to hear experiences or thoughts. Thanks.

VM Posted October 7, 2012 Report Share Posted October 7, 2012 Has anyone used the KM150 for booming? Indoors it's among the first choices ! Versus Schoeps MK41 or Senn MKH 50. Quote Link to comment Share on other sites More sharing options...

studiomprd Posted October 8, 2012 Report Share Posted October 8, 2012 " Anyone else? " why... you don't believe us ?? are you waiting for "us" to give you are approval to try it yourself?? approval granted. it will be your own personal choice made for mostly subjective reasons, and on the finished product, no one besides you, -and whoever else you let know,- will be able to recognize it.

VASI Posted October 8, 2012 Report Share Posted October 8, 2012 Yes you can. Alternative with great results is KM 184. Quote Link to comment Share on other sites More sharing options...
David Waelder Posted October 8, 2012 Report Share Posted October 8, 2012 I've used Neumann mikes, including the KM140 and the KM185, on booms with very pleasing results. They are outstanding microphones and perform very well. HOWEVER, I have not had consistently good results using them in a wireless boom configuration. When powered with a Denecke or PSC phantom power box, I have encountered low level background noise. In most circumstances, this is not objectionable as it is buried under the background noise of the stage or location. When the performer speaks very quietly and one needs to raise the gain, the background noise becomes objectionable. I don't know why this is. I sent the mikes back to the Neumann facility in Connecticut for service and for upgrading to the latest specs. On one occasion Neumann USA actually installed a new amplifier circuit board. While the problem was somewhat lessened, nothing seemed to cure it completely. When used with a cable to the mixer, everything was very good. When used with a radio link, not so good. Eventually, I gave up and acquired Sennheiser 8050 microphones that work excellently well with radio links. I haven't tried using the Neumann mikes with the Sound Devices portable pre-amps (MM-1, MP-1) but I think that might resolve the problem. By the way, the Neumann shotguns (81i, 82i) employ a different amplifier design and work just fine in radio boom configurations.

pkautzsch Posted October 8, 2012 Report Share Posted October 8, 2012 I'm regularly using the KM 185 for interior boom. It's basically the same as the 150, just a fixed-capsule design. Great sound, clean off-axis response, and a little more presence or "sparkle" than Sennheisers and Schoepses. They do need clean P48, though.

studiomprd Posted October 8, 2012 Report Share Posted October 8, 2012 " KM 185 for interior boom. It's basically the same as the 150, " in the know Neumann staff have confirmed that to be the case, the same electronics and the same capsule, but at a MI price point.

Wyatt Tuzo Posted October 8, 2012 Report Share Posted October 8, 2012 HOWEVER, I have not had consistently good results using them in a wireless boom configuration. When powered with a Denecke or PSC phantom power box. Just a reminder. The KM140 or 150 have impedence, but not signal balanced outputs. Pin 3 is hot on these mics, and pin 2 is shunted to ground (through a cap) inside the mic shell. In order to power these mics effectively from one of these portable power supplies, you will need to make a simple polarity reversal cable. If you want to get picky... just reverse the polarity again at the board. The 185 won't have this "problem" (it's not really that big a deal in practice). Hope this helps Quote Link to comment Share on other sites More sharing options...
David Waelder Posted October 8, 2012 Report Share Posted October 8, 2012 In order to power these mics effectively from one of these portable power supplies, you will need to make a simple polarity reversal cable. I ran them with reverse polarity wiring. Without the reverse polarity wiring, there is no audio at the transmitter. With it, there is audio but the problem of increased noise remains. I went to a lot of trouble over this and brought the issue to the attention of Neumann engineers on their users forum. If the answer were that simple, I would have adopted it and moved on. Wyatt, I do appreciate your suggestion - and it's on point - but something else is going on. David Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted October 8, 2012 Report Share Posted October 8, 2012 So sorry David, I used an excerpt from your post to provide a context. My post was not intended to be directed toward you personally. Im sorry that it came off that way. Anyway, I just thought it might be useful for the original poster or any others who are looking to use this setup... And hopefully it can be.

David Waelder Posted October 9, 2012 Report Share Posted October 9, 2012 It's OK. Sorry to be so hyper-sensitive but this particular vexing problem had me going in circles for months. David Quote Link to comment Share on other sites More sharing options...
bendybones Posted October 15, 2012 Author Report Share Posted October 15, 2012 Assuming a decent shockmount, how does the KM150 fare for hadling noise ? Also, there was mention in of the 184/185 needing alot of gain, is this also the case with the KM150? Quote Link to comment Share on other sites More sharing options...
Nate C Posted October 15, 2012 Report Share Posted October 15, 2012 KM150 is the interior mic I learnt on. Love and somewhat miss the neumann sound.recorded some great jazz trumpet on that mic. I have since gone the schoeps route.At the time schoeps was more affordable and available. Still wish (and someday will) to have a few neumanns in my arsenal. If you do music/dynamic recording the advantage of the in built pad is a saviour. Handling noise wise I would say it is similar to any of it's cousins (senn50 shoeps41) treat it gentle smooth and point in the right direction. I have used the 150 and the 41 and 50 in various mounts.. rycote white pointer, black ring(s)? and lyres without an issue. The 50 and 41 are somewhat guilty of wild noise but are still my my favourites outdoors when used properly. Quote Link to comment Share on other sites More sharing options...
bendybones Posted October 16, 2012 Author Report Share Posted October 16, 2012 Thanks. I should have been more specific and asked how it would compare to the Oktava Mk012 with regard to handling noise. I boom with the Oktava no probs, but sometimes I get a boom op who isn't that experienced, and can't hear the handling thru the G2 reciever I'm sending his headphone feed to.

David Lezynski Posted October 20, 2012 Report Share Posted October 20, 2012 KM150 is terrific indoors, especially in boomy kitchens and bathrooms. A lot less echo in hard rooms and a great bottom end. However it sounds like poo (scatological reference) outdoors. A mystery microphone, if you will. However, I would never sell the KM150.

pkautzsch Posted October 27, 2012 Report Share Posted October 27, 2012 Oktava is a nightmare handling noise wise. 185 is my go-to mic with low ceilings and small rooms. Larger/higher rooms often sound better through KMR81. Quote Link to comment Share on other sites More sharing options...
Aritzsan Posted October 28, 2012 Report Share Posted October 28, 2012 I've a pair of km150 and I use them mostly for stereo recording, and sometimes for booming in reverberant places and they work well. It sounds very similar to schoeps mk41. It needs more gain than a shotgun but it's not a problem if you have a decent preamp in your recorder. To have a good shockmount is extremely recommended with this mic. I use Cinela Osix1. Quote Link to comment Share on other sites More sharing options...
SoundHound Posted November 1, 2012 Report Share Posted November 1, 2012 I used the KK150 since it was first first issued and later the, acoustically identical, and substatially cheaper KM185 for decades. It is more durable than the Mk41 and I like the lively sound better. It is useful to have an on board low cut filter for the KK50 capsule There's a few NOS of the rare K100 electronic packages with a low cut switch (which eliminates the previously described pin 2 AC ground problem too) available. But realize that many of the Neumans still available today have a sensitivity to RF. I had described this problem (especially pernicious with camera mounted VHF TV viewfinder transmitters) to the microphone's designer, Stephan Peus, while I visited him in 2002 in Berlin. A while later (more due to TBS/Warner Borthers Sound Dept than myself) they modified the KM185 (SN above 50000) to be exceptionally RF immune. Meanwhile, my workaround for the RF problem was the Oktave MK012 with hypercardiod capsule. The Oktava has lots of low frequency response though. Recently, Oktave has issued an in-line low cut filter accessory (about $110). So you might want to try this filter before abandoning your setup. Also note that Oktave also has an in-line roght angle swivel adapter accessory too in, delayed, response to the "film" market. The Oktave gave me just about 90% of KM150/185 quality. If you are looking for that 5% you might try Michael Joly's mod of the electronics package (about $100 + postage). Just google Oktave Mod. Michael is an Oktava dealer so you could order the low cut filter and swivel from him too since I don't know a stocking LA dealer. Quote Link to comment Share on other sites More sharing options...
NCSOUND Posted November 3, 2012 Report Share Posted November 3, 2012 what about the frecuency response? the curve show that they begins to cut on 500hz, on 50hz it's on -10db. that's not a big deal on male voices? i' m asking because i own a kmr 81 and i'm thinking it can be a good mic to work on interior, but the only thing that is scare me is that low cut.

studiomprd Posted November 3, 2012 Report Share Posted November 3, 2012 " the only thing that is scare me is that low cut. " no need for being afraid... but you will have to decide if you like it or not, and of course listening would be the best way, but the answer is subjective.

Geoff Maxwell Posted November 4, 2012 Report Share Posted November 4, 2012 Great for reverberant spaces and as a plant. Needs a good preamp and a light touch. Quote Link to comment Share on other sites More sharing options...
JTsound Posted November 6, 2012 Report Share Posted November 6, 2012 I love this mic. It is smoother and not as bright as my Schoeps 41. It is better sounding in very live rooms though it has less bass response when we like that timber of a male voice. I still love it! Quote Link to comment Share on other sites More sharing options...
traut Posted November 10, 2012 Report Share Posted November 10, 2012 I have been using Neumanns for years. Used to be a Schoeps guy, but got tired of dealing with humidity problems. Bruce Bisenz gave me a pair of 150's and told me to use them for two weeks, then go back to my Schoeps. I did, and sold all my Schoeps. Currently I have 2 each 184, 185, km81, km82. For the short mics, the Cinela mount is the only mount that actually works, IMHO. Quote Link to comment Share on other sites More sharing options...
