A: Magma software cost. It is important to understand that the new U 67 is not a copy or clone. It is an original Neumann U 67 microphone, made to the exact same specifications. Key parts such as the output transformer are manufactured according to the original documents and production drawings from the Neumann archive. The most crucial part, the K 67 large diaphragm condenser capsule has always remained in production, as it was later used in the U 87 Ai. While the current K 67 differs from old specimens in minor cosmetic details, its acoustic design and build quality have remained unchanged over the decades.

NEUMANN – THE WORLD'S HIGHEST SOUND QUALITY SINCE 1928. Since 1928 the brand Neumann has been synonymous with perfect sound, pioneering research and development, and uncompromising quality. Rare is the recording – whether classical, rock or Pop, news broadcasts or radio dialogue – which doesn't feature at least one Neumann microphone. Neumann Black. My serial number 44759, how can I track down very close to it?? 0 TheViper Distinguished. Nov 26, 2006 289 0 18,960 22. Dec 21, 2009 #2 Nice mic. This is the closest surrounding dates to your U87 I can give you: U87 #31628 was shipped on U87 #32473 was shipped on Hope that gives you a clue. Best regards, Klaus Heyne P.S.: Neumann offers precise dating if you send them an e-mail. Go to the Neumann Pinboard and find the check box 'microphone dating'.
There are no intentional changes or modifications, either. The current U 67 is engineered to sound exactly like a U 67 microphone from the original production period. The tube circuit and the component values are identical. The frequency response of a new U 67 microphone matches that of an old U 67 made from 1960 to 1971 to the point that you could use them as a stereo pair (provided the old one is in good shape).
Please note that the limited production run of 1992 was adjusted for a slightly brighter response.* This was not repeated with the current reissue. Dj java decompiler. The new U 67 has the same essentially linear response as U 67 microphones from the 1960s.
*Note: The 1992s version response can be adjusted to the linear response by one minor adjustment by any Neumann service station.
How To Date A Neumann U67/U87 Capsule
Here is a rough overview of how to date K67/870 capsules installed in U67, M269, SM69, SM69fet, U87Ai, and K87 capsules used in U87 and U87i. (I will add photos later). The U67 and U87 types are identical in dimension, construction and acoustic design, except that the K87 uses a non-conductive spacer between the two capsule halves, and an isolation sleeve over the four capsule assembly screws, while the K67/870's spacer is made of conductive aluminum and the assembly screws are not sleeved.
Here then are the generations which are easily discernible even by non-experts.
1. 1960 to 1961. Similar appearance as early brass K47/49, but with two backplates mounted against each other with four M2 screws (if I recall correctly). Brass diaphragm rings, no threads in the backplates to screw the capsule into its mount. The U67 prototype, U60, used a clamping ring around the capsule; the first U67 production version was mounted with three tiny pointed set screws threaded into the mounting ring, similar to how M7 capsules were mounted to the U47 capsule mounting ring.
2. 1961 to 1966. Same as above, but capsule is held in the mount with four M2 slot screws (two are screwed into each backplate half)
3. 1966 to 1969. Brown fiberboard diaphragm rings replacing the brass rings
4. 1969 to ca.1980. First generation of plastic diaphragm rings (ivory color), whose 4 mounting screws were recessed into the plastic, to be flush with the ring's surface
5. 1980 to mid 1980s. Same as above, but with white instead of ivory-colored rings
6. Since mid 1980s. Same as above, but diaphragm mounting ring screws no longer recessed.
Versions 5 and 6 went through five generations combined; subtle differences through time are not easily noticeable by a casual observer. Likewise, it's initially not easy to separate a K67 from a K87 by looking at it. Upon closer inspection, you can see the 40μ aluminum separator ring between the two backplate halves on K67/870.
Since the late 1970s through 2009, all K67/87/870 are marked with a single digit, indicating the last digit of the year of manufacture (i.e. '7' for 1987, 1997, 2007, etc.) It is either marked with black felt pen or ink on the same ring with other production numbers, but in a separate space, or on the other diaphragm ring with no other markings.
Using a single number as year code can be confusing because numbers repeat every 10 years. But the combination of build characteristics and date number allows pinpointing the year of manufacture.
Since 2010, two digits are used to identify the year of manufacture. F. ex. Rick ross port of miami zip. Office 365 macbook download. '12' = 2012
