With the KU100, Berlin-based microphone specialist Neumann has developed a mic that is based on the human head and delivers stereo recordings that sound astonishingly three-dimensional when listened to on headphones, with decay and level properties that accurately correspond to human audio perception. The KU100 also minimises self-noise while delivering a high level of signal quality and covering a wide frequency response, and its maximum sound pressure level (SPL) is very high, which allows excellent dynamics to be achieved. All of this results in an experience almost identical to that which the listener would have if they were hearing the recording live at the recording position.
The Neumann KU100's two omnidirectional condenser capsules are built into artificial ears in order to reproduce the human perception of sound with astounding realism. Opening the catches on the back of the head-shaped enclosure provides access to additional flip switches for 10dB attenuation and the high-pass filter, the latter of which has -3dB corner frequencies of 8Hz (in the LIN position), 40Hz, and 150Hz and eliminates low-frequency interference such as structure-borne noise. A five-pin XLR output for the microphone signal is located on the base of the KU100's housing, alongside which separate left/right BNC outputs for unbalanced measuring are also provided.
The Neumann KU100 was developed by the manufacturer to generate an extremely realistic sound image that is best suited to listening through headphones, and this makes it the perfect microphone for audiobook, virtual reality, concert, and nature recordings. What is more, it is also ideally suited to measuring the sonic clarity of different speaker systems and optimising the acoustic properties of rooms. The KU100 can be supplied with phantom power by either the connected recording equipment or the included mains adapter during stationary operation, while mobile use requires batteries that can be inserted by opening the back of the unit. DAT recorders and measuring equipment can be connected via the two BNC outputs.
Georg Neumann GmbH was founded in Berlin in 1928 - and is certainly one of the most famous brands of microphones in the world. However, this is not the company's only sphere of activity. For many years, the versatile inventor and pioneer Georg Neumann was also involved with vinyl record cutting machines and the development of rechargeable batteries. The technology he developed is still the basis for this now crucial and rapidly expanding market. What is more, for many years the company built highly personalised sound control systems for broadcast studios/theatres and concert halls, and for several years also studio monitors. In 1991, Neumann became part of the Sennheiser group of companies, and in 1999 was the first German company to receive the Technical Grammy for their overall technical achievements.
The Neumann KU100 offers the user a high degree of freedom in terms of installation thanks to its two thread connections - one on the back and one on the base - and it comes in a sturdy carrying case that ensures safe transport. As mentioned above, the base of the KU100 features a five-pin XLR output for connecting an IC5-type microphone cable, and the scope of delivery also includes an additional adapter cable for connecting to a multi-track recorder. To ensure optimum binaural recordings, the KU100 can be calibrated using an optional measuring microphone capsule, which is inserted into the respective ear from the outside using a pistonphone adapter and used to level the microphone at a specified SPL. What is more, users can intuitively mix recordings using the free Ambeo Orbit plugin.
