Neumann M 149 Large Diaphragm Tube Condenser Microphone

Nine-pattern tube mic with K 49 capsule, seven filter positions
MFR# 8399

Product Description

The Neuamnn M 149 Tube is a large diagram condenser microphone modeled after Neumann’s famous M 49 microphone. Combining the classic K47/49 large diaphragm capsule with Neumann’s innovative transformerless tube circuit, the M 149 offers the best of both worlds: the unmistakable sound of analog tube amplification and the flexibility of modern low-noise microphones. Featuring 9 selectable polar patterns and a 7-position low cut filter, there’s nothing the M 149 can’t do.


The M 149 Tube is inspired by a long lineage of innovative microphones. Inspired by the legendary M 49 microphone, released in the 1950s as a modernized version of the iconic U 47, the M 149 continues the tradition of combining the unmistakable Neumann tone with innovative new features.

Equipped with the classic K 47/49 dual large diaphragm capsule, the M 149 Tube delivers the same balance and unmatched presence found in the M 49 and U 47. The capsule signal is then amplified by a subminiature triode tube to ensure minimal self-noise. Finally, the M 149 introduces an all-new high-precision, ultra-low distortion transformerless output stage, for improved transient response.


The M 149 is one of the most versatile microphones ever made. Capture the perfect amount of ambience in any situation with nine selectable polar patterns including omni, wide cardioid, cardioid, hypercardioid, figure-8, and four intermediate positions. Fine tune your tone at the source with the 7-position low cut filter, offering bass reduction from 20 Hz to 160 Hz in half-octave steps. Combined with an incredibly low self-noise of 13 dB-A, the M 149 Tube is a truly universal microphone for the modern studio.

Just like its predecessors, the M 149 is a superb vocal microphone, but unlike most tube mics, it also excels at capturing intimate performances. Perfect for piano, acoustic and electric guitar, upright bass, percussion, drums overheads, as well as solo strings, brass and woodwind instruments and more, the M 149 is ideal for recording almost any sound source.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
