Neumann M147 Tube overview

  • 1Description

The M 147 Tube Microphone from Neumann is a vacuum tube large diaphragm condenser microphone with a cardioid polar pattern. The pressure gradient, dual diaphragm capsule is the K 47/49, inherited from the legendary U 47 and M 49 microphones. Following the tube is a transformerless output circuit providing low self-noise and high output gain without adding color to the signal.

The M 147 Tube delivers high output levels, allowing the microphone to feed cables up to 984.3' in length without signal degradation. The side address capsule features a cardioid polar pattern, which is effective in minimizing ambiance and noise coming from the off-axis sections of the microphone. The capsule features a flat frequency response to the upper mid-range, and a boost of up to 3 dB above 2 kHz. The M 147 Tube is a suitable microphone for recording vocals and general instruments such as strings, piano and wind instruments.

Tube Circuitry
The M 147 Tube features a combination of solid state and vacuum tube circuitry. The Vacuum tube design provides a type of warmth and definition not often found in solid-state circuitry.
K 47/49 Dual Diaphragm
Featuring the K 47/49 dual diaphragm, adapted from the legendary M 49 and U 47 Tube microphones. The M 147 maintains the level of sonic character at a modest price point.
Quality Output Circuitry
The Transformerless output design provides a low noise floor and output gain high enough to feed cables up to 984.3' in length without degradation in signal.
Cardioid Polar Pattern
The cardioid polar pattern effectively minimizes off-axis noise caused by room ambiance, instruments, monitors etc. The pattern offers a more generous pick up area with lower range frequencies.
N 149 A Power Supply
The Neumann N 149 A power supply effectively powers the microphone and is compatible with both the M 149 and 147 microphones.
