The M 149 Tube is a large-diaphragm condenser microphone with switchable polar patterns. It is the first new 'Tube' microphone design from Neumann in over 30 years, and also the world's first transformerless tube microphone.
The head grill is instantly recognisable to vintage Neumann afficionados as that of the classic M 49/M 50. The capsule (K 49), also from the M 49, is a select version of the K 47 capsule from the famous U 47.
The M 149 Tube has the lowest self-noise of any tube microphone on the market and features 9 polar patterns switchable on the microphone body. There is also a 7 position high-pass filter on the rear of the microphone body. The circuitry of the M 149 Tube includes a tube amplifier coupled with the FET 100 transformerless circuitry as used in the award-winning TLM 50 microphone.
By incorporating modern technology with the tube amplifier, Neumann are able to produce a tube microphone with unprecedented specifications. Vintage and modern technology combined!
