The Neumann KM 184 D 48SPD Cardioid Digital Microphone is a further development of the successful KM 100 series. The passive capsule design can be combined modularly with an analog (KM A) or digital (KM D) output stage in accordance with the AES 42 standard. The considerably smaller microphone capsules (available in 8 directional patterns - cardioid included, all sold separately) and an extensive program of accessories permit excellent adaptation of the microphone system to a wide range of applications.
Through the use of the most up-to-date electronic components the system offers many electroacoustic and operational advantages, such as lower self-noise, a wider dynamic range and very high immunity to electromagnetic interference. The acoustics of the capsules were taken from the proven KM 100 system.
The KM D digital output stage converts the signal from the capsule directly into a digital signal. The result is an AES/EBU signal with 24 bits and a large dynamic range. The integrated digital signal processor (DSP) permits remote control of the microphones, including the digital gain, pre-attenuation (6 dB, 12 dB or 18 dB) and low-cut filter (0 Hz, 40 Hz, 80 Hz or 160 Hz). An integrated peak limiter and compressor/limiter with additional de-esser function prevents any overloading of the audio signal.
The modular solution permits the microphone capsule to be separated from the output stage by a distance of up to 100 m. The LC 4 microphone cable with a length of 5 or 10 meters is available as a standard solution (sold separately). Alternatively, capsule extensions of different lengths, swivel joints and stand mounts, etc. (all sold separately), can be used for a flexible system setup.
