Brand
NEUMANN
Capture high-definition sound with incredible isolation using the legendary Neumann KM 150. Originally introduced as a key milestone in Neumann's premier KM 100 modular series, this compact, high-performance small-diaphragm condenser microphone is highly sought after by collectors, live sound engineers, and studio professionals alike.
Neumann KM 150 Miniature Hypercardioid Condenser Microphone
The Neumann KM 150 is a professional miniature hypercardioid condenser microphone developed for demanding recording, broadcast, live sound, and installed audio applications. As part of Neumann's acclaimed KM 100 modular microphone system, it combines a compact form factor with exceptional sonic precision, making it an excellent choice for orchestral recording, theatre productions, television, film, conferences, and acoustic instrument capture where discreet placement and outstanding audio quality are equally important.
Built around the AK 50 hypercardioid capsule and the KM 100 output stage, the KM 150 delivers highly accurate sound reproduction with excellent off-axis rejection, low self-noise, and a wide dynamic range. Its modular construction provides exceptional installation flexibility, allowing the capsule to be separated from the output stage using compatible extension accessories for applications where space or microphone visibility is critical.
Designed for Precision Audio Capture
The KM 150 is engineered to reproduce sound with exceptional transparency and detail while maintaining the natural tonal balance of the original source. Its carefully designed hypercardioid pickup pattern provides excellent isolation from surrounding sound sources, making it particularly effective in acoustically challenging environments.
Whether recording classical ensembles, theatrical performances, spoken word, or acoustic instruments, the microphone delivers clear, focused audio with excellent intelligibility and minimal coloration.
Hypercardioid Directional Pattern
The AK 50 condenser capsule features a hypercardioid polar pattern that provides tighter directivity than a conventional cardioid microphone. This allows greater rejection of unwanted ambient noise while maintaining natural sound reproduction from the desired source.
- Highly focused sound pickup.
- Excellent rejection of off-axis sound.
- Improved isolation in live environments.
- Suitable for critical microphone placement.
- Consistent frequency response across the pickup area.
KM 100 Modular Microphone System
One of the defining characteristics of the KM 150 is its modular architecture. The microphone consists of an active capsule and a separate output stage, allowing engineers to configure the microphone for numerous professional applications using compatible KM 100 system accessories.
This modular design enables remote capsule placement, ceiling suspension, podium installations, hidden microphone positioning, and custom mounting configurations while maintaining the microphone's outstanding audio performance.
Transformerless Electronics
The KM 150 incorporates Neumann's transformerless output circuitry, delivering a clean, transparent signal with low distortion and excellent transient response. This design ensures accurate reproduction of fast musical transients while providing reliable operation in professional recording and broadcast environments.
- Transformerless output stage.
- Low distortion audio path.
- Excellent transient accuracy.
- Low self-noise.
- Balanced professional output.
High Sound Pressure Handling
The KM 150 is capable of handling demanding sound sources while maintaining excellent audio quality. A switchable 10 dB pre-attenuation pad increases maximum sound pressure handling, allowing the microphone to perform confidently during loud orchestral passages, percussion recording, amplified instruments, and live productions.
Its combination of high SPL capability and low noise performance makes the microphone suitable for both delicate acoustic recordings and powerful live sound applications.
Professional Applications
- Broadcast and television production.
- Film and location sound recording.
- Classical music recording.
- Orchestras and chamber ensembles.
- Choirs and vocal ensembles.
- Theatre productions.
- Conference and installed sound systems.
- Acoustic instrument recording.
- Speech reinforcement.
- Professional studio recording.
Compact Professional Design
The compact dimensions of the KM 150 allow discreet positioning in situations where visual impact must be minimized without sacrificing audio quality. Its lightweight construction makes it suitable for suspended installations, camera rigs, podiums, stage productions, and remote microphone placement.
The robust metal construction ensures long-term reliability in demanding professional environments while maintaining the precision engineering expected from Neumann products.
