With this amazing Neumann tube mic as the front end of your signal chain, you'll be capturing sounds with new levels of realism and warmth. The M 149 Tube is a variable dual-diaphragm microphone. The K 49 capsule – well-known from the legendary U 47 and M 49 microphones – is followed by a tube functioning as an impedance converter, with a transformerless output circuit design which can feed long mic cables without any coloration.
The M 149 Tube is a superb vocal microphone. The capsule is mounted elastically inside the headgrille to eliminate structure-borne noise. The surface below the capsule is shaped like a cone to disperse any reflected sound from the acoustic upper half space. This avoids any interference with the primary sound arriving at the capsule directly. A large headgrille surrounds the capsule. It is acoustically very open and therefore increases the sonic realism.
The polar pattern switch selects one of nine directional patterns: omnidirectional, wide-angle cardioid, cardioid, hypercardioid, figure-8, and one additional intermediate pattern between each major position. A seven-position slide switch selects a high-pass filter, advancing in half-octave steps between 20 Hz and 160 Hz (-3 dB).
The included N 149 (STANDARD) power supply feeds the M 149 Tube through an 8-core cable. The output connector for the audio signal is a 3-pin balanced XLR. The microphone comes as a set in an attractive case, together with the 8-core microphone connecting cable, the N 149 power supply with plug-in mains unit, the EA 170 full elastic microphone suspension and a dust cover. Also included is a separate wooden box for protection and storing the microphone safely.
An optional vintage-style power supply is available, item # N149VINTAGE.
