Product Overview

The KM 185 mt Stereo Set is engineered for precision and maximum isolation. While cardioid pairs are standard, this hypercardioid set is designed for engineers who need to capture a specific soundstage while aggressively rejecting noise from the sides and rear. Each pair is meticulously matched at the Neumann factory to ensure identical frequency response and sensitivity, providing the perfect phase-coherent foundation for specialized stereo arrays and immersive audio setups.

Product Description

The Specialist for Tight Isolation:

The KM 185 mt is a pressure gradient transducer with a hypercardioid pattern that remains remarkably consistent across all frequencies. It offers superior rejection of unwanted sound at the $120^{\circ}$ angle, making this stereo set ideal for recording instruments in close proximity (like a string quartet or drum kit) where you want to hear the intended source with zero "smearing" or bleed from neighboring performers.

Faithful & Transparent Audio:

True to the Neumann Series 180 philosophy, this set provides a faithful reproduction of the acoustic event. It does not impose a heavy "sonic footprint," making it perfect for capturing the natural character of acoustic guitars, pianos, and orchestral soloists. The frequency response is smooth and linear, with a subtle treble lift around 10 kHz that adds a sophisticated "brilliance" to your stereo image.

Innovative Transformerless Design:

Both microphones feature Neumann’s high-end transformerless circuitry, which ensures a pristine signal path. With a massive dynamic range of 127 dB and a self-noise floor of only 15 dB-A, this set captures the quietest room nuances and the loudest transients (up to 142 dB SPL) with equal ease. The low-impedance output allows for long cable runs of up to 300 meters without any loss in signal quality.

Visual Discretion for Broadcast:

The Matte Black (mt) finish is specifically designed for professional media. Its non-reflective surface ensures that the microphones do not create glare under studio lights, making them the gold standard for television, film sets, and live concert broadcasts.

Key Features

• Matched Stereo Pair: Factory-selected for perfect acoustic symmetry and phase coherence.

• Hypercardioid Pattern: Maximum side/rear rejection ($120^{\circ}$) for superior isolation.

• Vivid Sonic Detail: Linear response with a slight $10\text{ kHz}$ boost for high-end "air."

• Extreme SPL Tolerance: Handles up to 142 dB without distortion—ideal for percussion.

• Matte Black (mt) Finish: Non-reflective coating for professional on-camera use.

• Premium Presentation: Includes a high-quality wooden box, swivel mounts, and windscreens.

Applications

• Drums & Percussion: Ideal for stereo overheads or "spot" miking to eliminate stage bleed.

• Acoustic Ensembles: Captures a focused stereo image of strings, brass, or woodwinds.

• Classical Vocals: Provides a natural, transparent sound for choirs and soloists.

• Broadcast & Film: Discreet profile for capturing high-fidelity audio on-set.
