Description


Legendary Design
Developed in close cooperation with Nordwestdeutscher Rundfunk (Northwest German Broadcasting), the M 50 was the counterpart to the no less legendary M 49. While the latter was a high-quality all-purpose microphone for varying acoustic environments, the M 50 was designed as the ultimate pressure transducer microphone for use in concert halls and dedicated recording spaces.

In practice, this meant that the M 50 was mainly used for recording orchestras, e.g. as the main pickup in various spaced omni configurations. In the 1950s, when the record label Decca experimented with stereo miking techniques, various setups, microphones, and pickup patterns were tried. In the end, the Neumann M 50 was selected as the perfect fit for what is now known as the Decca Tree configuration, i.e. three microphones mounted in a triangle with the outer microphones facing outward. To this day, a Decca Tree setup, often extended with additional outriggers, using Neumann M 50 microphones remains the prime choice for experienced engineers in classical music and film scores. The vivid imaging of this setup in combination with the M 50's outstanding resolution produces unparalleled results. Today, extended versions of this technique are being used for surround and immersive recordings. Of course, the M 50 has also produced excellent results in other applications, e.g. piano recordings or as a spot mic for string sections and soloists. In pop contexts, the M 50 has been used for miking ensembles or brass sections and as a room microphone, e.g. on drums.

Unique Properties
Finally, the legend is available again! The much-anticipated M 50 V is a reissue of the last revision of the 1960s, the M 50 c. Over the years, the M 50 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 250, was issued with an RF-proof connector.

The M 50 V is a faithful reissue of the historical M 50 microphones produced by Neumann from 1951 to 1971. It uses the same acoustical concept with a small diaphragm omni capsule, flush mounted in a 40 mm acrylic sphere. This design produces a unique polar pattern, which is omnidirectional at lower frequencies and becomes gradually more directional above 1000 Hz. At the same time, the frequency response shows a smooth rise towards higher frequencies, compensating treble loss in the diffuse field and giving the microphone more reach. Being a true pressure transducer, the M 50 has a powerful bass response down to subsonic frequencies, without proximity effect. At the same time, its increasing directivity at higher frequencies offers optimal imaging in stereo, surround, and immersive configurations.

Over the production period of the historical M 50, several capsule types were employed, using different membrane materials. The M 50 V uses an improved version of what is considered the most desirable capsule type, the K 53 with an ultra-thin metal diaphragm, famous for its extremely fast and accurate transient response. The K 33 Ti in the M 50 V uses the same capsule acoustics as the coveted K 53 but with a metal diaphragm made of titanium. Being a lightweight yet rigid material, titanium is an ideal material for metal diaphragms, contributing to the outstanding transient response of the M 50 V. Additionally, titanium offers excellent long-term stability. In fact, the entire K 33 Ti capsule including its backplate and housing is made of titanium, which yields ideal matching regarding mechanical and temperature stability.

The M 50 V uses the same circuit as the M 50 c, but with an even lower noise subminiature tube. This tube has already proven its exquisite sonic qualities in the M 49 V, where it is used in an almost identical circuit. As radio frequency interference has increased dramatically in recent years, due to mobile phone networks and Wi-Fi, the RF-proof connector has been adopted from the M 250.

The included NM V power supply is designed to automatically provide the optimal heater voltage for both the M 50 V and any historical M 50; it also automatically adapts to the local mains voltage. Since the same NM V power supply is used for the M 49 V, it includes a pattern control, which of course is of no consequence for the M 50 V with its fixed omni capsule. This power supply can also be used for all historical Neumann microphones using a Telefunken AC701 tube.

Additionally, the M 50 V Set includes the iconic yoke mount, whose flexible positioning has contributed to the M 50's popularity. As an improvement over 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. The M 50 V set is delivered in a high-quality case, which, like the entire microphone, is handmade in Germany.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
  • USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
