Neumann M 147 TUBE | Cardioid Tube Mic with K47 Capsule, includes N149A, SG1, KT8 and Case Nickel

The Neumann M 147 TUBE Cardioid Tube Mic with K47 Capsule is a high-quality vacuum tube condenser microphone designed for professional audio recording. This mic stands out with its cardioid characteristic, which ensures excellent directional sensitivity. It incorporates the legendary K 47 dual diaphragm capsule, which has been inherited from iconic predecessors like the U 47 and the M 49. This ensures that the M 147 delivers the warm, rich, and detailed sound signature that Neumann microphones are renowned for.

The heart of the M 147 is an advanced tube technology functioning as an impedance converter, followed by a transformerless output circuit that ensures an extremely low self-noise level. This innovative combination of tube and solid-state circuitry earned the M 149 Tube a TEC Award in 1997, and the M 147 continues this legacy. The microphone is adorned with an elegant satin nickel finish, making it a visually appealing addition to any studio setup.

One of the standout features of the M 147 TUBE is its ability to feed extremely long microphone cables without any audio degradation. The microphone is provided as a complete set in a high-quality aluminum case, which includes a microphone cable, a metal swivel mount for a mic stand, and a compact universal power supply. Additionally, the modern manufacturing process allows Neumann to offer this high-performance microphone set at an attractive price point.
