Neumann M147 Tube large-diaphragm condenser microphone - early production, serial # 1284 - is in EXCELLENT condition, and perfect working order. This microphone has been used in a private, smokeless studio, and has always been stored in its original case.

It pairs the legendary K 47 capsule from the vintage U 47 with a modern, low-noise solid-state output stage. based on the model's now legendary predecessors, the U47 and the M49. Components like Neumann’s famous capsules are assembled by hand in state-of-the-art clean rooms and individually tested for extreme consistency.

 German Manufacturing: Unlike mass-market brands that outsource to low-wage countries, Neumann manufactures in Germany, maintaining high labor standards and precise build tolerances. 

This microphone is designed for professional studio recording with a warm, vintage Neumann-style tone ideal for vocals and instruments.

The famous legendary K 47 capsule which offers full frequency response, 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.

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 the majority of valve microphones, the M147 is accompanied by a separate power‑supply unit, the N149A. This is a switched‑mode device capable of accepting mains supply voltages between 90 and 250V at either 50 or 60Hz, and generates ±70V for the valve and capsule biasing as well as +32V and +5V supplies. These are all filtered to prevent supply‑rail interference reaching the mic, and are conveyed over a supplied 30'cable with screw‑locking eight‑pin DIN connectors.

A sensor line is incorporated, which prevents the power supply from energizing when the microphone is disconnected. This sensor loop also ensures that correct operating voltages are maintained even over long cable runs — the manual suggests that up to 100m of cable can separate the PSU and the mic.

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 with keys, a microphone metal swivel mount for a mic stand, and a compact universal power supply for standard mains sockets.

This microphone was used in a home studio (no smoking ever), and always treated with the utmost respect of a music lover and producer.
