Title: The New Neumann KM-A mics w/ KK caps
Post by: OOK on March 28, 2012, 11:51:13 PM
Has anyone tried the new Neumann KM-A mics.  I see there is a fully digital version (KM-D).  They look like a cross between the km100 series and the km-184 series.  Maybe something like the older KM84 mics.  The price seems reasonable too.

These should sound exactly the same as the corresponding KM 100- or KM 180-series mikes. But the capsules are somewhat less expensive than the "active capsules" of the KM 100 series, because the Schoeps patent has run out, so Neumann (and parent company Sennheiser) are now free to build active accessories without having to put FET circuitry in the capsules any more to work around the patent.

There is no special resemblance to the older fet 80 microphones such as the KM 84--that's a total misimpression there, I'm afraid.

The KM-A (and KM-D) capsules are basically the same as the KM180 and KM 100 series.

The circuitry is the latest design and is a bit better than the others.

I have several of the KM-D series omni heads and find them excellent.

Though if you want the sound of the old KM 84 you will need to get the Gefell M300  ;)

Thanks......for all the info.  They certainly look temping.

Already knew that about the gefell m300 ;).

Are they going to be coming out with active cables for this series?  With the number of contacts on the body at the capsule end it definitely looks like it.

When did Schoeps' patent run out?

I would highly recomend a pelican 1040 case with the 1042 pick and pluck foam.  Not sure where your located.  I am in PA and use B+H for most things.... I have no affiliation with B+H....I just find there site very easy to use, cheap, fast shipping to my area.

Peli - yes / pick and pluck foam - no !

I take my Peli cases to a local flight case company and get them custom foamed - much much better.

Ya well, i found that schoeps case for $20.00. I know i should get something better but i dont take these km84's out in the field, i want to, actually never have. That might change this summer.

Please tell me more about the sound of the Gefell M300 emulating the old Neumann KM 84.  I have never heard that before your post.

I would not say it's an "emulation".

Gefell is the original company started by Georg Neumann in 1928 - you can read the complete history HERE (http://www.microtechgefell.de/index.php/en/history).

During the war, Neumann moved the complete factory to Gefell to avoid the bombing and the factory got trapped in the east after the war.  Georg Neumann set up Neumann Berlin and the two factories had good contacts until the Berlin Wall went up in the early 1960s.

So Gefell is really the original Neumann.

Gefell is still owned by the Neumann family (Georg Neumann KG own Microtech Gefell as I understand it), Neumann Berlin is now owned by Sennheiser (though the Neumann part is still in Berlin and is made to traditional Neumann standards).

The original Neumann M7 capsule is only made at Gefell.

The Gefell M300, as many people say, is close to the KM84 in sound - much closer than the newer KM184.

I hope this helps.

John:

Great info. Thanks for sharing it here.

Do you know if the KM84's have the metal diffuser in front of the diaphragm, like the M300's do? That's the most unique difference between the M300's and most other mics I'm aware of. I've assumed that was the reason the M300's sound the way they do.

I'm not aware of anyone that has the newer version, but I've thinking about buying two kk184 capsules and a new LC4 cable to replace my current km140 active setup terminated to PFAs. I don't need Neumann bodies for any reason, so a kk/lc4 setup would come in around $1650. Not bad, IMO, for such a high quality setup and a safer option in terms of getting caps serviced long term. Time will tell if I decide to pull the trigger. Would probably help if another taper has experience with the kk series.

The capsule of the M300 is actually very different from the KM184.

The M300 uses a ceramic capsule - as I understand it, this is hot-pressed ceramic with a thin coating of chromium to make the back-plate metallic.  This is then covered with a 1-micron layer of Teflon as an insulator.

The ceramic capsule is unique to Gefell as far as I am aware.

Each manufacture will damp the capsule so that it has the optimum frequency response curve they desire.

Hugh Robjohn's "Brief History of Microtech Gefell" penned in 1999 makes interesting reading - the PDF is here (http://www.sound-link.co.uk/pdf/A%20Brief%20History%20of%20Microtech%20Gefell.pdf).

The KK184 will only connect to a KM-A or KM-D body via the remote cable and not anything else.

So, if you get the KK184 you will definitely need a KM-A or KM-D as well.

I have a pair of the KM-D and a pair each of the KK183 and KK131.

Thanks for the info DSatz! Could you briefly explain the FET circuity? And this should have NO effect on the sound of the capsule/noise floor of the microphone, correct?

Thanks :)

That refers to the old AK heads, not the new KK ones, which are quite different.

Specific to this application, the only difference is the location of the FET (in the cable vs. the capsule head).

You can't have a remote cable without first converting the impedance of the signal from the microphone capsule . If the powering requirements of the FET circuit are different (maybe they are, but I kind of doubt it), then it's simply a matter of making the proper measurements to design the proper PFA circuit.

It's basically the same here in Germany. I couldn't find a single merchant online carrying it. However, it is listed on Sennheiser's price list (http://de-de.sennheiser.com/global-downloads/file/5730/Sennheiser_Preisliste_Neumann_2015.pdf) (search for 008606). List price is 284 EUR + VAT. So I guess your local distributor will be able to order it for around that price.

Well? Considering that I quoted my own modified setup, then bothered to correct this misinformation... I guess I must not have been wrong. Sure would be nice if a product ambassador could answer this honestly. We'd probably see a lot more Neumann products sold to users on this board.
