THE EASIEST WAY TO CREATE 3D AUDIO
Conventional recording techniques attempt to transfer an acoustic event into the listener's environment. The result is often unsatisfactory because the original room is put in a second room. Dummy head recordings are a much more immediate experience, because they transfer the listener into the environment where the acoustic event originally took place. In addition, head-linked stereo recordings are truly immersive: while conventional stereo recordings are limited to left and right and, at best, a sense of depth behind those speakers, head-linked recordings create a three-dimensional sound image surrounding the listener.

The KU 100 dummy head is a binaural stereo microphone. Two omnidirectional condenser capsules are integrated into artificial ears mounted on a speaker resembling a human head. KU 100 recordings played back on high-quality headphones thus offer listeners an experience almost identical to what they would have heard with their own ears at the recording position, with astonishing lateral and vertical localization and a breathtaking sense of space and room decomposition surrounding the listener. Immersive sound has never been easier: simply place the KU 100 at the optimal listening position! Unlike older dummy head microphones, the KU 100 is also compatible with loudspeaker playback, creating a stereo image similar to conventional microphones but with a superior sense of space and depth.

Thanks to its state-of-the-art transformerless circuitry, the KU 100 has very low self-noise and can handle high sound pressure levels of up to 135 dB without audible distortion and up to 145 dB with the -10 dB pre-attenuation switch activated. A second switch offers three low-cut options, 150 Hz, 40 Hz and linear. Both switches affect both channels. The KU 100 has a balanced 5-pin XLR stereo output and unbalanced BNC outputs. Three power options are available: P48 phantom power, internal battery and external power supply (included). The KU 100 mounts on standard microphone stands at the top or bottom, with a 5/8"-27 female thread, plus thread adapters to connect to 1/2"- and 3/8"-studs.

APPLICATIONS
Due to its natural and transparent sound, the KU 100 can be used for all kinds of head-related recordings. Typical applications range from classical recordings and radio drama productions to experimental pop and ambient recordings. In addition, the Neumann KU 100 is also often used for industrial applications, for example documentation and noise examination in automobiles or workplaces.

Although it uses only two channels, its spatial representation appears three-dimensional and shockingly realistic. The KU 100 can be used to great effect in music and audio drama productions. In addition, KU 100 recordings are compatible with loudspeakers.

Since 1928, the Neumann brand has stood for excellent sound quality, innovation in research and development, and uncompromising manufacturing. Manufactured in a clean room with the highest level of quality control, Neumann microphones benefit from 87 points of manual verification per microphone.
