Neumann KM 185 D
The Neumann MK 185 D has a pressure gradient transducer with hypercardioid characteristic. Attenuation of sound incidence from the side or rear is approximately 10 dB. Minimum sensitivity occurs at an angle of about 120°.
Neumann has repeatedly set new standards in the field of analog microphone technology. The first condenser microphone, switchable directional characteristics, the first stereo microphone and 48 V phantom power were all developed by Neumann, introducing new dimensions to the field of microphone and recording technology.
With the digital Solution-D microphone system, Neumann has now succeeded in bringing the dynamic range and signal fidelity of the best analog studio microphones into the digital realm. This means that, for the first time, the whole audio production signal chain is entirely digital.
Optimal A/D conversion, especially developed synchronization technology and the capability of controlling standard microphone parameters and various integrated signal processing functions remotely ensure that Solution-D meets the most demanding professional audio production requirements. The basic technological principle is to permit recording with no "bottlenecks" associated with loss of signal quality.
The comprehensive features provided by Solution-D make it possible to achieve excellent quality with small digital productions – with only a single microphone and a recording device.
The KM D microphones are the digital counterparts of the well-known successful miniature microphones of the 180 series. The KM 184 in particular is regarded as a standard-setting analog miniature condenser microphone, and is one of the most popular of all Neumann microphones.
With the digital models KM 183 D, KM 184 D and KM 185 D, three different directional characteristics are being offered; the KK 131, KK 143 and KK 145 capsule heads do offer 3 additional characteristics. The modular construction of the new microphones permits the KM D output stage to be combined with the various passive microphone capsules.
In the microphone, the Neumann A/D converter which has been extensively proven in the D-01 receives the output signal directly from the capsule. With a dynamic range exceeding that of the capsule, the converter permits optimal utilization of the capsule qualities. This ensures that the capsule signal is made available to the recording system without any coloration, with a hitherto unknown transparency.
If required, the DSP functions integrated into the microphone can be configured and controlled remotely via the DMI-2 digital microphone interface and the RCS remote control software. These functions include gain setting, a compressor/limter with an additional de-esser function, and a peak limiter. The digital concept proves particularly beneficial here. The peak limiter, which receives the output signal almost directly from the capsule, acts as an automatic "safety valve", permitting safe exploitation of the entire available dynamic range even in stressful recording situations.
For the purpose of clear identification, information concerning the name of the manufacturer, model, serial number and installed software version is transmitted by the microphones to the connected receiver.
The microphones are equipped with a 3-pin XLR connector for transmission of a bi-directional signal conforming to the AES 42 standard. This signal includes the balanced digital microphone output signal, the phantom power supply, and a remote control data stream that also contains a signal for synchronizing the microphone with a master clock.
