Neumann M 149 TUBE | Dual-diaphragm Condenser Microphone

ไมโครโฟนสำหรับบันทึกเสียง Neumann M149 Tube เป็นไมโครโฟนแบบ vacuum tube large diaphragm condenser microphone, รูปแบบการรับเสียง 9 directional characteristics, ตอบสนองความถี่ 20 Hz to 20 kHz, Impedance 50 Ohms, 7-position low cut, มาพร้อม power supply N149

The M 149 Tube is a modern version of Neumann’s famous M 49 microphone. Like its predecessor, it uses the classic K47/49 large diaphragm capsule in an acoustically open headgrille. The M 149 is a universal studio microphone with 9 selectable polar patterns. Its innovative transformerless tube circuit ensures optimal sound with lowest self-noise.

The M 149 is a universal studio microphone with tube electronics in the tradition of the legendary M 49, the large diaphragm condenser microphone that raised the standard of audio recording in the 1950s and has shaped the sound of countless jazz and pop albums ever since. The M 149 continues in this tradition, augmenting the timeless fidelity of its predecessor with updated technology and improved performance specs.

The M 149 uses the same sound transducer as its famous predecessor, the classic K 47/49 large diaphragm capsule, renowned for its supreme balance and unmatched presence. This delicate dual diaphragm capsule is housed in a large, acoustically open headgrille, which minimizes internal reflections.

The capsule signal is then amplified by a subminiature triode tube, specially selected for lowest noise and optimal transmission characteristics. The final stage is a high-precision, ultra-low distortion transformerless output stage, which preserves the full dynamics of the preceding tube circuit and is optimized for 21st century signal chains.

The M 149 offers higher sensitivity and much lower noise than vintage tube microphones. And thanks its current sensing technology, which ensures optimal operating conditions for the tube, and its low output impedance, the M 149 can drive long cable runs of up to 300 m without transmission losses.

It was this innovative combination of classic tube technology with state of the art Neumann engineering which earned the M 149 a prestigious TEC Award in 1997.
