Description Product Description The Neumann M 147 Tube is a vacuum tube condenser microphone with cardioid characteristic. At the heart of this microphone is the K 47 dual diaphragm capsule, inherited from this model's now legendary predecessors, the U 47 and the M 49. Following the capsule is a tube that functions as an impedance converter. The next stage is an efficient, transformerless output circuit, that guarantees an extremely low self-noise level. Note: This innovative combination of current tube technology with the most advanced solid-state circuitry was decisive in awarding the 1997 TEC Award to the related M 149 Tube mic. The M 147 Tube mic 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. The microphone is delivered as a complete set in a high-quality aluminum case. Included with the microphone are a microphone cable, a metal swivel mount for a mic stand, and a compact universal power supply for standard mains socket-all at a very attractive price.Applications The famous capsule, together with complimenting tube characteristics, makes the M 147 Tube especially well suited as a vocal mic. In addition, it is a superb spot mic for all types of musical instruments. The extremely low self-noise of its tube circuitry makes the mic perfectly suited for use in modern recording chains, analog and digital.Acoustic features The M 147 Tube is addressed from the side. The capsule is equivalent to the one used in the U 47, and is the deciding factor in determining the mic's sound characteristics. It has a flat frequency response to the upper midrange, and a boost of up to 3 dB above 2 kHz. The headgrille design is a smaller version of the U 47. It protects the capsule effectively against popping and wind noise.Polar pattern The Neumann M147 Tube has a cardioid characteristic, leaning more toward super-cardioid due to its distinctive capsule design.
