. Designed for critical recording and live-sound operations the KM184 is a small diaphragm, cardioid condenser microphone. Its capsule and electronics are identical to those of the KM1240. By omitting the -10dB pad switch and making the KM184 cardioid only, Neumann is able to offer a microphone that provides maximum performance at a price much lower than previously possible. the KM184 can handle sound pressure levels of 138dB before overloading, making it particularly useful for percussion, cymbals, hi-hats and brass instruments. It is also extremely quiet (16dB A-weighted self noise), making it excellent for the caputring the subtle nuances of acoustic guitar and orchestral performances.
