Neumann KK 143 nx
The Neumann KK 143 nx is a next-generation wide cardioid condenser microphone capsule designed for use with Neumann’s KM A and KM D output stages. As part of Neumann’s new “nx” capsule series, it combines state-of-the-art acoustic design with legendary Neumann sound quality. Offering a slightly wider cardioid pickup pattern, the KK 143 nx delivers a natural, open tone with precise spatial imaging — making it ideal for orchestral recordings, acoustic instruments, and room capture in professional studio and broadcast environments.
The KK 143 nx features a refined pressure gradient transducer design that ensures exceptional linearity, low distortion, and an extended frequency response. The wide cardioid pattern provides excellent balance between direct sound and room ambience, resulting in a transparent and realistic recording. When paired with the KM A (analog) or KM D (digital) output stages, it forms a compact, flexible, and reference-quality microphone system built for modern recording standards.
