Product Overview

The KM 183 mt Stereo Set provides a ready-to-use solution for high-fidelity spatial recording. While the "Series 180" is famous for its cardioid KM 184, the KM 183 is the essential choice for engineers who prioritize unlimited low-end and a natural, "open" soundstage. The microphones in this set are meticulously selected to ensure identical frequency response and sensitivity, providing the phase-coherent accuracy required for professional A-B stereo and ambient surround arrays.

Product Description

The Art of the Spaced Pair (A-B Stereo):

The KM 183 mt is a true pressure transducer. Because it captures sound from all directions equally, it provides a sense of "air" and spatial immersion that directional microphones cannot replicate. When used as a spaced pair (A-B stereo), these microphones deliver a lush, wide stereo image with perfect phase stability, making them the first choice for recording symphony orchestras and grand pianos in world-class halls.

Diffuse-Field Equalization Explained:

Unlike many omni mics that sound "dark" at a distance, the KM 183 mt is diffuse-field equalized. It features a deliberate +7 dB treble boost at 10 kHz in the free field. As you move the mics further back into a room (the diffuse field), the natural high-frequency roll-off of the air balances this boost, resulting in a perfectly flat and transparent response. For close-miking, simply angling the microphones slightly away from the source can neutralize this boost for a smoother top-end.

Invisible Low-End Authority:

One of the greatest strengths of the KM 183 mt is its limitless bass response. Because there is no proximity effect, the low-end remains clean and powerful whether the mic is 10 cm or 10 meters away. It accurately captures the fundamental frequencies of pipe organs and double basses down to 20 Hz, ensuring your recordings have the weight and authority of a live performance.

Discreet for Professional Media:

The "mt" (Matte Black) finish is designed specifically for the visual demands of modern production. The non-reflective surface ensures that the microphones do not cause glare on television or film sets, allowing them to be placed prominently as spot mics or hung from ceilings while remaining nearly invisible to the camera.
