Neumann KK 145 nx
The Neumann KK 145 nx is a next-generation cardioid condenser microphone capsule designed for use with Neumann’s KM A and KM D output stages. As part of Neumann’s advanced “nx” capsule series, the KK 145 nx delivers a natural, transparent sound with a refined low-frequency roll-off — optimized for close-miking and spot-miking applications. Its precise tonal balance and smooth off-axis response make it ideal for professional studio, broadcast, and classical recording environments.
Building on the success of the classic KK 145, the new “nx” version features improved linearity, lower self-noise, and enhanced acoustic consistency. The gentle low-cut filter reduces proximity effect while preserving the warmth and clarity of the original source, ensuring perfectly balanced recordings even in close placement situations. When combined with Neumann’s KM A (analog) or KM D (digital) output stages, the KK 145 nx provides a compact, modular, and high-resolution microphone system with exceptional versatility.
