Neumann Microphone Tube M147
The 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, transformer less output circuit that guarantees an extremely low self-noise level. 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.
