Neumann M 147 Tube Set is a premium large-diaphragm tube condenser microphone that revives the legendary sound of Neumann’s 1950s classics, such as the U 47, while integrating advanced 21st-century engineering. Combining the iconic K 47 capsule with a modern transformerless output stage, the M 147 delivers vintage warmth with exceptional clarity, low noise, and a full, powerful tone.
At its heart lies the same large-diaphragm capsule found in the Neumann U 47, renowned for its musical balance and presence. The capsule’s signal is amplified through a carefully selected subminiature triode tube, adding smooth harmonic saturation and a natural sense of loudness. The transformerless solid-state output stage allows for long cable runs up to 300 m without loss of detail, ensuring pure signal transmission with extended low-end response.
The M 147’s cardioid pattern and distinctive midrange focus make it ideal for vocals, voiceovers, film dubbing, and solo instruments. Unlike many other tube microphones, the M 147 maintains an impressively low self-noise of only 12 dB-A, making it suitable for quiet sources as well. It handles higher SPLs with gradual tube-style saturation up to 134 dB SPL, providing the pleasing analog compression engineers love.
Combining vintage tone with modern precision, the M 147 Tube is the perfect choice for studios seeking classic Neumann warmth, rich harmonic depth, and a timeless aesthetic. Each set includes the microphone, N 149 A power supply, EA 1 shock mount, and connecting cable.
