The Neumann KU 100 is a dummy head binaural stereo microphone designed to provide an accurate reproduction of sound as heard by a human for musicians and audio engineers in music recording sessions, measurement and analysis, and film, television, and sound effects production. With low-noise transformless circuitry and a microphone capsule mounted in each ear of its head, the KU 100 produces accurate and realistic stereo imaging.A selectable high-pass filter with three positions—flat, 40 Hz, or 150 Hz—allows you to tailor the 20 Hz to 20 kHz frequency response to control rumble and excessive low frequencies. Activate the -10 dB pad to prevent distortion when capturing loud sources. Outputs include two unbalanced BNC jacks and a balanced XLR 5-pin connector. The KU 100 can be operated via battery power, phantom power, or the supplied external power supply. It includes an XLR 5-pin cable, an XLR 5-pin to dual XLR 3-pin adapter, and a sturdy aluminum carrying case.
