Selling my extra M582 tube small diagram condenser microphone. This is the much more desirable threaded version. The package includes the M582 body (from the 60's), a M70 capsule (likely from the 70's), a power supply unit that Scott Hampton bought in Slovakia and a 20 ft. tube microphone cable by Schaal Audio.

Unlike M582 mics with the M62 screw-on capsule you can use a wide range of different capsules with this M582 threaded preamp body. It will work with any of the other threaded capsules including: the UM70 (the multi-patterned version of the M71 that switches between cardioid, omni and figure-8—although the figure-8 only works with MV69x mics), the M71 (cardioid only version, just like the M7 or M7s capsule for the CMV-563), the M69 omni, the M58 omni, the M93 (which essentially is just a M58 but released later), the M73 cardioid shotgun capsule and potentially a few others I have read about but have never seen. The other beauty of these capsules is that they also work with the solid-state version MV690, MV691 and MV692 preamp bodies (if you already have any of those or want to further expand your sonic palette down the road).

NOTE: This listing no longer includes the M94 capsule. But if you are interested in both capsules let me know and we can figure something out.

The microphone body shows some wear so I've listed the package as Very Good condition, but the rest of the items are in Excellent condition. Everything works fine (recently checked out by Hamptone), but due to its vintage nature it is sold as is. I still offer a 3-day return window though if there are any issues not described in the listing (less shipping fees).

More Info about M582 microphones and M70 Capsule

M582 Tube Preamp Body (threaded version)
Type: Condenser Microphone
Tube: EC92 (or 6AB4)

The M582 microphone body preamp (first released in 1958) is nearly the same as the CMV563 (first released in 1956), just in a smaller body (but uses the same PSU). The UM57 is also nearly the same (but that mic requires basically the same PSU except with added control to select the voltage to activate the remote pattern selection between Cardioid, Figure-8 and Omni). All three of those microphones use the EC92 tube or 6AB4 tube. Unlike the U47, with a similar overall circuit but uses the extremely rare VF14 tube instead, quality NOS EC92 and 6AB4 tubes can still be found for under $100 (versus literally thousands of dollars for a NOS VF14 tube if you can find one). 

M-70 Capsule
Pattern: Cardioid (Back absorption: >20 dB)
Type: Small-Membrane (Nickel-foil), Pressure Gradient Transducer
Frequency Response: 50 - 16,000 Hz

The M70 capsule also utilizes a nickel-foil membrane, but slightly different than the one used in the M94. The M70 is more linear with a slight bass roll off for close proximity mic'ing. Making it slightly more flat and neutral sounding than the other capsules, less hyped in the highs (perhaps halfway between a KM84 and vintage AKG 451E/EB in terms of brightness). The M582/M70 combo can be a little more of a utilitarian/safe/less-colored choice between the capsules, especially useful if you are worried the source may be a little too bright and harsh to begin with—like some cymbals, shakers, tambourines and acoustic instruments can be at times.

A Brief History of Neumann Microphones (East and West)

Early Years
Georg Neumann and Erich Rickmann establish the limited partnership Georg Neumann & Co in 1928. The Olympic Games in Berlin in 1936 provide the first live test for the classic M 7 electrode in a tube set-up as developed by Georg Neumann. The so-called “Neumann bottle” can already be equipped with different capsules in order to change patterns. In 1938 Erich Rickmann dies. Despite the heavy loss, Georg Neumann is able to continue leading the company to full extent and according to the ideas of is deceased co-partner - due to his close cooperation with manager Erich Kühnast ever since the founding days.

During the Second World War, the principal laboratory in Berlin undergoes damage both by fire and bombs. To avoid further bombings, the entire company and the principal laboratory are transferred to Gefell. Both the Neumann and Kühnast families, as well as almost all employees relocate to Gefell. In Gefell, production continues of the “Neumannbottle” CMV 3 using the large diaphragm capsule M 7 developed by Georg Neumann. The M 7 microphone capsule is also utilized in many other famous models developed by Neumann including:
  • U 47, U 48, M 49
  • CMV 563, UM 57, UM 70 capsule, M 71 capsule

Unbeknownst to Georg Neumann and Erich Kühnast, the town of Gefell would become part of the Soviet Union at the conclusion of World War II. Around this time Georg was invited by the French government to set up a lab in Paris, while Mr. Kühnast continued his work in Gefell. Some members of the original Neumann staff returned to their home city of Berlin and started a branch company which acted as a repair center for Neumann brand products in West Berlin. This "off shoot company" became the roots of a company which began in 1948, and was also known as "Neumann,” but more specifically Georg Neumann GmbH (versus Georg Neumann & Co in Gefell). Together with the rest of the staff, Erich Kühnast remains in Gefell. Georg Neumann assigns to him the management of the limited partnership Georg Neumann & Co. At first, the following products manufactured include:
  • Condenser microphone CMV 4 with capsule M7 (cardioid) or 026/2 (omni)
  • Condenser microphone CMV 5/B with the capsules M 7, M 8, M 9 and 026/2
  • Microphone connector 6... NS 84/85 and NS 86/87

During the 1950s, radio stations in Germany are rebuilt and production in Gefell continues, both of the earlier microphone types and of new ones including:
  • Tube microphone preamplifier CMV 563
  • With the microphone capsules M 55 (omni), M 7 (cardioid), M 8 (figure eight) and M 9 (omni) as well as M 7 S, M 8 S and M 9 S with short handles
  • Tube condenser microphone UM 57, switchable patterns, omni-cardioid-figure eight
  • Tube microphone preamplifier M 582 with M 58 (omni)

The limited partnership Georg Neumann & Co. and Georg Neumann GmbH agree to equally use the Gefell trademark as created by Erich Kühnast. In order to distinguish both companies, Georg Neumann GmbH adds a diamond in the background while Georg Neumann & Co. uses a circle in the background.

Neumann "Berlin" and Neumann "Gefell" worked very closely together until 1961 when the wall was erected in Berlin that separated the West from the East. While key engineering staff worked at both facilities, the managements of the two companies stayed in contact (illegally as far as the Soviet authorities were concerned) and Georg Neumann also made regular visits to Gefell (until his passing in 1976). Before the separation the tube microphone preamplifier M 582 was developed along with the microphone capsule M 58 (omni) and was first released in 1958. After the separation the addition of the other capsule models including the M 62, M 70, M 71, M 94 continued through the 60’s and into the 70’s.

1970’s - Present
On April 24th 1972 the limited partnership Georg Neumann & Co. in Gefell is expropriated and renamed VEB Mikrofontechnik Gefell. Further use of the Neumann trademark is prohibited by the Soviet Union. Instead, products are now marked with the brand RFT.

The first metal diaphragm microphones for precision recording were invented by the original company, Neumann Gefell, and continued to be manufactured throughout their history. Some of the more famous Neumann Berlin metal diaphragm microphone models have included the KM-54, KM-56 and SM-2 (and SM-23) stereo microphones, but the diaphragms for these microphones were not made in the Berlin factory. During the next 40 years Gefell accelerated the development of tube technology which as everyone knows, continued in eastern Europe while the west developed transistors.

In 1989, with the collapse of the Eastern Block and the subsequent fall of the Berlin Wall, Georg Neumann’s family saw the opportunity to regain their company in Gefell. By this time, the Berlin factory was in trouble. The company had expanded into other areas, which included disc cutting (vinyl) and custom console manufacturing, neither of which were sustainable businesses. In 1990, the Berliner Bank shut down the Georg Neumann GmbH Berlin factory, and arranged to sell the company to Sennheiser, who immediately moved what was left of the "diamond logo Neumann" you know today to the Sennheiser assembly line.

In 1993 'Georg Neumann & Company Gefell, GmbH' was given back to its original owners, the Neumann family. Ownership of the company today is retained by the directors of Microtech Gefell with the official name being 'Georg Neumann KG' (no relation to the Sennheiser Corporation's 'Neumann' brand name, a name which Sennheiser purchased in 1991 with the other assets of the bankrupt Neumann).

Microtech Gefell condenser microphones are manufactured using the original techniques and exclusive processes developed by Georg Neumann. The products they manufacture include the world's most accurate measurement microphone capsules, the world's only metal diaphragm microphones, and the venerable "M-7" capsule which saw it's rise to fame in Neumann Berlin manufactured models like the U-47, U-48 and M-49. The M-7 is the only large diaphragm microphone capsule to use PVC based diaphragms which sound much sweeter and more musical than the subsequent Mylar based KK-47 capsule found in later model U-47, U-48 and M-49 microphones. Just as they were originally, Microtech Gefell microphones are still hand built, individually tested and measured to ensure a quality level that is unsurpassed.
