Top-of-the-Line Neumann Mic!

The Neumann M 147 tube condenser microphone is absolutely top-of-the-line, the ideal cardioid microphone for the fully professional recording studio. Its transformerless output, low self noise and high dynamic range are the result of proven Neumann components and modern construction.

Neumann M 147 Tube Condenser Microphone at a Glance:
  • Highly sensitive mic for capturing the "air" around instruments or vocals
  • Legendary K 47 capsule offers full frequency response
  • Tube-based impedance converter and transformerless output for low self noise

This cardioid mic captures the "air"
Part of the M 147's appeal comes from its extreme sensitivity - 20mV/Pa - that allows it to capture the ambience of a sound. It's spatial characteristics are so refined, you'll wonder if you hung a stereo mic by mistake! The M 147 can translate any sound's special qualities onto a recording, making it an excellent microphone for acoustic guitar or bass, horns and any kind of vocals. But don't stop there - you can put the M 147 up against an instrument amplifier and get outstanding results, too!

A classic capsule for the best sound reproduction
At the heart of the M 147 is the famous K 47 capsule, familiar to Neumann users from the popular U 47 and U 47 FET mics. The M 147 also features a frequency response of 20Hz to 20kHz. Recognized by pros worldwide as one of the finest mics available, the M 147 is a must-have tool for vocalists and an extremely welcome addition to any sophisticated studio setup.

Tube design plus transformerless output
Following the M 147's capsule is a tube impedance converter. Then comes a Neumann-standard efficient, transformerless output circuit that guarantees an extremely low self-noise level. This innovative combination of current tube technology with the most advanced solid-state circuitry was recognized with a 1997 TEC Award to the M 147's sister M 149 mic.

The M 147 Tube can feed extremely long microphone cables without affecting the quality of the audio signal. Like all Neumann tube microphones, the M 147 Tube comes with an elegant satin nickel finish.

Neumann M 147 Tube Condenser Microphone Features:
  • No-compromise large-diaphragm condenser mic
  • Famous Neumann K 47 capsule with single polar pattern (cardioid)
  • Ideal for vocals and acoustic instruments
  • Signal/Noise ratio 82 dB (DIN/IEC 651)

Best "U-47 knockoff" mic I've used

Now, I'm not qualified to compare this mic to a vintage U-47 so I won't even try. However, I'm familiar with several "boutique" U-47 clones, a few of which I've owned, and I can tell you that this mic beats all of them hands down. I had owned the M-149 for years, didn't like it much and rarely used it. When I sold it I had no interest in the M-147, thinking they would probably be similar in character. Not so! This mic is a totally different animal, much easier on the ears. It has a rounded, solid, satisfying bass response that's perfect for many male vocals and a silky treble that's great on acoustic guitars. On electrics it's fantastic a few feet away from the cab at an angle, paired with a dynamic mic close-up on the grille. I've owned mine about 3 years and I use it all the time. I know I'll never sell it.

Neumann M147 delivers

I have owned this mic for close to 10 years now and it continues to be The mic in the vocal booth. Paired with an Avalon 737 preamp or sometimes a UA 610 MkII this mic will give you a great sound. BUT, as always, some singers require a darker mic because they sound harsh or raspy, and the M147 will show it abundantly. It is best suited for smooth vocals, male or female, with resonance and proper singing technique. I never use this mic on guitar, violin, or cello (my main instrument)- I prefer Neumann KM140s and AT 4081 (active ribbon) for those applications because a large tube diaphragm mic brings out qualities that don't need to be emphasized. Overall this is a great mic that delivers.

Classic Neumann mojo, but not for everything.

No frills cardioid tube transformerless capacitor mic. Sounds like a Neumann, which is what you pay for. Vintage sweet high-mid detail and warmth. You need a nicer pre to pair with this mic, like a Grace or a Sytek, something clean and solid-state. I always need to lift up some 11-13k shelving to really bring out it's sheen, more or less depending on your choice of pre. This mic is not an overall swiss army type. It excels in some things, ok on most things, and downright blows on some things. The things I like it for: Kick (18"-24" outside front), sweet and soft female vocals, ride cymbal, bass cabinet (right up on the grill), Fender clean tone, and some acoustic guitars. It sucks on raspy, aggro, or screamo male vocalists, drum mono o.h.,guitar od/dist, tambourine, and Hammond. The best application? Banjo! Ukulele! Mandolin! 12 string acoustic! Really captures the transients like magic. The mic is built to last 100 years, but I feel it is a tad overpriced. Nonetheless, mine is a keeper.

Go for the U87

This is not a bad mic, but the mid range can be a bit harsh and honky. I recommend spending the extra thousand and picking up a U87, which sounds much better. If you are looking for the transformerless tube mic of your dreams, check out the M149. The M149 has a much higher sticker price, but is quite possibly the best LDC mic on the market and very smooth and natural compared to this mic.

Review of the Neumann M-147

I own this mic and will give a basic review of its pros and cons. This mic is a bit like owning a vintage car. Its a classic based on the legendary neumanns the Beatles used. Its got a tube for that warm sound and the mic is beautifull with a gorgeous case with classic shockmount. It comes with a power supply. Tube mics require periodic maintenance which can be expensive. To get the most from this mic if used for vocals, you will need a high quality preamp which is a big added expence. When you factor in these items you might want to reconsider going with a tube mic if you are on a budget.
