True Greatness

Introduced in 1951, the M 49 revolutionized studio technology with its continuously variable, remote-switchable polar pattern. And, of course, with its incomparably full, silky sound, which has made its mark on countless recordings to this day. The M 49 V is what many have been eagerly waiting for: a reissue according to original specifications!

The Beginning of Something Big

The M 49 is a great microphone in every respect. For as impressive as its physical appearance is its incomparable sound. With its revolutionary technology, the M 49 has set new standards altogether. The M 49 is a true Neumann legend.

Everything and More

The objective itself was grand: in the early 1950s, a reference microphone was developed in cooperation with the Nordwestdeutscher Rundfunk (Northwest German Broadcasting) that was to replace all previous ones. Instead of having to replace the capsule in order to change the directional characteristic, the M 49 allowed remote controlling the polar pattern from the power supply – continuously. With its balanced frequency response in all directional patterns from omnidirectional to cardioid to figure-8, including intermediate settings, the M 49 is a truly universal microphone: be it orchestra, piano, trumpet, or vocals, the M 49 is suitable for recordings of all kinds to the highest standard. As a result, the M 49 was, and still is, in great demand. No other Neumann microphone of the tube age was manufactured for a longer period: from 1951 to 1971. Countless legendary recordings from cool jazz to present day pop bear its elegant sound signature. The M 49 is an inseparable part of the Neumann DNA.

The Best of the Best

At last, the legend is available again! The M 49 V is a reissue of the last revision c. Over the years, the M 49 was continuously improved: the originally installed Hiller tube MSC2 was replaced by the Telefunken tube AC701 and then the AC701k. This and other circuit changes improved the signal-to-noise ratio, dynamic range, and immunity to interference. In parallel, a broadcast version, the M 249, was issued with an RF-proof connector.

The M 49 V uses the same circuit as the M 49 c, but with an even lower noise subminiature tube. Since high-frequency interference has increased dramatically due to mobile phone networks and WiFi, the RF-proof connector has been adopted from the M 249.

The included NM V pattern control unit is designed to automatically provide the optimal heater voltage for both the M 49 V and any historical M 49; it also automatically adapts to the local mains voltage. Additionally, the M 49 V set includes the iconic yoke mount, whose flexible positioning has contributed to the M 49’s enormous popularity. The M 49 V set is delivered in a high-quality case, which, like the entire microphone, is handmade in Germany.

Compatibility and order options

The M 49 V has two internal switches that can be used to establish compatibility with various historical circuit variants (see below, “A Brief History of the M 49”).

In the standard delivery state, the M 49 V is fully compatible with the last historical variant M 49 c with a 1st order high pass at 30 Hz.

Using the internal switch S4, the high pass frequency can be lowered to 12 Hz. This results in the low frequency response of the early M 49 (without suffix) until 1957, which did not yet have this high pass. At the same time, a certain protection against infrasound is maintained.

Using the internal switch S2, the M 49 V can be set to a fixed cardioid pattern, as was possible with the historical M 49 b variant. This deactivates pattern adjustment; sensitivity increases by about 2 dB, and the equivalent noise level decreases by about 3 dB. This setting is useful if the M 49 V is to be used exclusively in cardioid mode, e.g. for vocals or speech.

The internal switches should not be operated by the user, but only by Neumann Service.

In the standard delivery state, the high pass filter is set to 30 Hz, and pattern control is activated. If you wish a different delivery state, you can order the M 49 V from your dealer or Neumann sales partner in the desired switch setting (Made To Order).

A Brief History of the M 49

The Neumann M 49 is without question one of the great microphone legends. Its incomparably full and silky sound remains unmatched to this day. Stars such as Barbra Streisand, Neil Diamond, and Huey Lewis even bought their own M 49 microphones in order to bring out the best in their voices in every studio. Although, as a matter of fact, the M 49 was not developed specifically for vocal recordings, but as a universal microphone.

Its development was initiated by the broadcast sector. Until the end of the 1940s, trying a different directional pattern meant exchanging the entire microphone or at least the capsule head. This did not change until 1949 with the introduction of the Neumann U 47, the first microphone that allowed electronical switching between cardioid and omnidirectional mode. The broadcasting community wanted a microphone that went even further and could be continuously adjusted from omnidirectional to cardioid to figure-8. In addition, the directional characteristic was to be remotely switchable from the control room. Not only was this convenient, it also allowed the selection of the most suitable polar pattern under optimal listening conditions. A great advantage when, as was common at the time, even large ensembles such as orchestras and big bands had to be recorded with just a few microphones. At the same time, the broadcast industry expected a simplification of its equipment inventory, as this uncompromising universal microphone would cover almost every conceivable application.

The first prototypes were developed at Nordwestdeutscher Rundfunk (NWDR) under the direction of Dr. Herbert Großkopf. Neumann secured his patent for the continuously switchable directional characteristic and produced the M 49 starting in 1951.

Thanks to its revolutionary technology and its balanced sound in all directional patterns, the M 49 easily held its own alongside the U 47, which had been introduced only two years earlier, even though the M 49 was considerably more expensive. No other Neumann microphone of the tube era was manufactured for a longer time: a full 20 years, from 1951 to 1971; the last units were sold until the mid-1970s. To this day, the M 49 remains one of the most sought-after studio microphones, especially for vocal recordings.

Masterwork in Progress The M 49 was produced in different versions.

  • The original version used a tube specially developed for microphone applications by the Hiller company, the MSC2.
  • From 1954/55 on, the Hiller tube was replaced by a lower noise tube from Telefunken, the AC701, which was specifically developed for microphones.
  • In 1957, the M 49 b appeared with a new output transformer (BV11) and some circuit changes. This reduced distortion and increased sensitivity. In addition, there now was an internal switch to deactivate the rear diaphragm, so that the M 49 operates with a fixed cardioid characteristic. This increased the signal-to-noise ratio by about 3 dB.
  • Starting in 1958 (serial number 1600), an improved low-microphonics version of the Telefunken tube was installed, the AC701k.
  • Around the same period, the M7 capsule originally used was replaced by the improved K 49 version. Acoustically, both capsules are almost identical. The K 49 offers manufacturing advantages that ensure better symmetry of the front and rear systems. In addition, the diaphragm material of the K 49 is much more durable than the PVC used previously, which becomes brittle over the years.
  • In 1964, the M 49 c was released, with further circuit changes. By changing the tube operation from "fixed bias" to "self-bias", noise could be reduced again. This was and is the most popular revision; many older M 49 microphones were later converted to the circuit version c.

In parallel, a special broadcast version was produced from 1961 on. The M 249 uses an RF-proof 7-pin Tuchel connector instead of the bayonet connector. Again, there are different revisions:

  • The M 249 (without suffix) was produced only from October to November 1961.
  • The M 249 b, introduced in November 1961, is technically equivalent to the M 49 b
  • The M 249 c from 1964 on corresponds to the M 49 c

The M 49 V Compared to Its Predecessors

The M 49 V uses the same circuitry as the last and most popular revision, the M 49 c. Only the Telefunken AC701k tube, which is no longer available, was replaced by an even lower noise type, also in subminiature format.

Like all M 49 microphones since the late 1950s, the M 49 V uses the K 49 capsule, which Neumann continues to manufacture unchanged. Its incomparable sound is legendary and cannot be improved upon! The large, acoustically open microphone basket, which has been retained in the M 49 V, also contributes to the unique sound characteristics of the M 49.

Since electromagnetic emissions have increased dramatically in recent decades, due to mobile phone networks and WiFi, among other things, the RF-proof connector of the broadcast version M 249 was adopted. The ancient bayonet connector of the M 49, which has not been available for decades anyway, would not have provided sufficient immunity against interference in modern studio environments.

The M 49 V set includes the newly designed power supply NM V. Since the new, very low-noise subminiature tube requires a somewhat higher heater voltage, the M 49 V should not be operated using historical power supplies. Conversely, however, the NM V can also be used for old M 49 microphones. An automatic function ensures that the optimum heating voltage is always provided for the tube used. In addition, the NM V automatically adapts to the local mains voltage. Nevertheless, it is not a modern switch mode power supply but a conventional linear power supply – for sound reasons!

The M 49 V set is completed by the popular yoke mount. It has always made the M 49 particularly flexible in terms of positioning and, together with the microphone, forms an iconic unit. In this mount, the M 49 can be seen in countless session photos, including such seminal albums as Miles Davis' Kind of Blue and many other recordings from the legendary Columbia Studios in New York City. Compared to the historic yoke mount, the new version has been supplemented with elements for mechanical decoupling of the microphone as well as a cable holder to suppress cable-related structure-borne noise.
