The Neumann M 147 Tube is a cardioid microphone that uses the classic K 47 large diaphragm condenser capsule, known for its combination of warmth and presence. The headgrille is a slightly more compact version of the iconic U 47 capsule head. The capsule signal is amplified by a classic tube circuit using a specially selected subminiature triode, which provides a vintage sound character.
Unlike vintage microphones that relied on large audio transformers for impedance conversion, the Neumann M 147 Tube employs a state-of-the-art transformerless solid-state output stage. This design allows for long cable runs up to 300 metres without transmission losses and ensures a direct sound with unrestricted bass response. The microphone is designed for 21st-century recording chains, offering a ‘modern punch’ alongside its vintage acoustic design.
The Neumann M 147 Tube is suited for vocals, speech applications such as voice-over and film dubbing, and as a spot microphone for solo instruments. It is capable of handling quiet sources due to its exceptionally low self-noise of 12 dB-A. While the typical SPL for low distortion is 114 dB, the microphone can handle louder sources, with distortion rising slowly to 5% THD at 134 dB SPL. This behaviour creates a sense of elevated loudness through soft saturation, similar to analogue recording.
The Neumann M 147 Tube is supplied in nickel colour and includes the M 147 Tube Microphone, N 149 A Power Supply including power cable, SG 2 Swivel Mount, KT 8 Microphone Cable, Dust Cover, and Aluminium Case. The matching connector for the microphone is DIN 8 F, while the power supply uses an XLR 3 F connector.
