Neumann KM 100 Modular Small-Diaphragm Condenser Microphone Output Stage

Neumann KM 100 Modular Output Stage for KM 100 Series Microphone Capsules

The Neumann KM 100 is the active output stage of the historic KM 100 modular microphone system, developed to provide exceptional flexibility and uncompromising audio performance for professional recording applications. Designed to operate with Neumann's interchangeable AK Series active capsules, the KM 100 enables engineers to configure microphones with different polar patterns while maintaining the renowned sonic transparency, low self-noise, and precision expected from Neumann small-diaphragm condenser technology.

The modular architecture allows the KM 100 output stage to be paired with compatible AK capsule heads, including omnidirectional, cardioid, wide-angle cardioid, hypercardioid, figure-8, and speech-optimized variants. This versatility made the KM 100 series a preferred choice for studio recording, classical music production, broadcast, film, television, live sound, and location recording where different directional characteristics were required without changing the complete microphone.

Modular Microphone System

The KM 100 forms the foundation of Neumann's historic modular miniature microphone system. Instead of using a fixed capsule, the active output stage accepts interchangeable AK Series capsules, allowing users to quickly adapt the microphone for specific recording applications. This modular approach provides exceptional flexibility while maintaining consistent audio quality across the entire microphone system.

The system also supports a comprehensive range of extension cables, swivel mounts, remote accessories, stereo bars, suspension mounts, and installation hardware, making it suitable for discreet microphone placement in concert halls, broadcast studios, theatres, film productions, and live performance environments.

Professional Audio Performance

Engineered with Neumann's transformerless circuitry, the KM 100 delivers clean, transparent signal transmission with excellent transient response, high dynamic range, and reliable operation. Powered by standard 48 V phantom power (P48), the output stage ensures consistent performance across demanding professional recording environments.

The compact design minimizes visual impact while providing maximum positioning flexibility for applications where discreet microphone placement is essential.
