Neumann M147 Valve Microphone
Product Info
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, transformerless output circuit, that guarantees an extremely low self-noise level. The M 147 Tube can feed extremely long microphone cables without changing 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 sockets.
