Neumann M 147 Tube Mic Kit (Used)
Perfect working order with case, leads and power supply. Serviced, in fair cosmetic condition, with some obvious signs of tarnishing to body and slight discolouration to grill and metalwork. Includes 3 months warranty.
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. 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 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 sockets. Our modern manufacturing methods makes it possible to offer this complete set at a very attractive price.
