Neumann M 147 Tube Large-Diaphragm Cardioid Tube Condenser Microphone

Neumann M 147 Tube Large-Diaphragm Cardioid Tube Condenser Microphone

The Neumann M 147 Tube is a premium large-diaphragm tube condenser microphone that combines the unmistakable sonic character of Neumann's legendary vintage tube microphones with the performance and reliability demanded by modern recording studios. Featuring the renowned K 47 large-diaphragm capsule—derived from the iconic U 47—and an innovative tube amplifier with a transformerless output stage, the M 147 Tube delivers exceptional warmth, presence, low noise, and outstanding transient response for professional recording applications.

Designed for professional music production, broadcast, voice-over, film dubbing, podcasting, and studio recording, the M 147 Tube captures vocals and instruments with remarkable detail, rich harmonic depth, and natural clarity. Its fixed cardioid pickup pattern provides excellent isolation from unwanted ambient sound while maintaining a smooth, balanced frequency response, making it an ideal microphone for critical recording sessions.

Legendary K 47 Capsule with Modern Tube Technology

At the heart of the M 147 Tube is Neumann's legendary K 47 large-diaphragm condenser capsule, celebrated for its warm low end, articulate midrange, and detailed high-frequency response. The capsule is paired with a specially selected subminiature vacuum tube that adds subtle harmonic richness while maintaining exceptionally low self-noise.

Unlike traditional tube microphones that use large output transformers, the M 147 Tube incorporates a transformerless solid-state output stage. This advanced design delivers extended low-frequency performance, outstanding signal integrity, and the ability to drive microphone cables up to 300 meters without noticeable signal degradation.

Outstanding Performance for Vocals and Solo Instruments

The M 147 Tube is particularly well suited for lead vocals, voice-over recording, narration, podcasts, and acoustic instruments where warmth, presence, and detail are essential. Its tube circuitry provides gentle, musical saturation as sound pressure levels increase, producing a natural analog character that enhances recordings without sounding harsh or overly compressed.

With an exceptionally low self-noise of just 12 dB-A, the microphone is equally capable of capturing quiet performances with remarkable clarity while handling louder sources with smooth overload characteristics up to 134 dB SPL.
