![]() A second switch selects the cutoff frequency of the high pass filter to be either linear, 40 Hz, or 150 Hz. Or from an external AC mains supply (included with the system).Ī 10 dB switch inside the head attenuates the sensitivity. With batteries as part of the internal battery supply, It can be powered in three different modes:įrom an external P 48 phantom power supply, The dummy head provides balanced (XLR) and unbalanced (BNC) outputs. As with traditional transformers, this technique ensures good common mode rejection, and prevents RF interference, that may influence the balanced audio signals. The usual output transformers are replaced by electronic circuits. The Neumann KU 100 Dummy Head Stereo Microphone uses transformerless circuitry with the advantage of high output capability, fast transient response, and extremely low self noise. In addition, the dummy head is frequently used to examine and document the influence of noise in industrial applications at various working places under realistic conditions.ĭes weiteren wird der Kunstkopf zur Untersuchung und zur Dokumentation von Lärmeinflüssen an Maschinen und an Arbeitsplätzen unter wirklichkeitsgetreuen Bedingungen eingesetzt. The dummy head is also contributed essentially as an important tool to preserve natural sounds of all kinds. The KU 100 dummy head is just as easy to use during creative radio drama productions, and music recordings where the room acoustics should be recorded at the same time. However, a superior quality is added, that of a distinct spatial depth perception. When played back through loudspeakers, the sound matches to a high degree that of conventional stereo microphones, placed in the same position. When the recorded audio signal is reproduced through high quality headphones the listener perceives a sound image almost identical to the one he would have heard at the recording location of the dummy head (head related stereophony). The KU 100 dummy head is a replica of the human head with a microphone built into each ear. Inside the head are additional switches for 10 dB attenuation and the high pass filter. The KU 100 can be operated with typical 48 V phantom powering, or from an external power supply unit, or from the built in battery.Īt the bottom of the unit is a switch for the different power supply modes, as well as connectors for balanced and unbalanced output signals. The dummy head is also used in many industrial applications as a measuring device, for example in acoustic research. ![]() When using the KU 100 dummy head, the binaural stereo experience moves the listener into the scene of the original performance, in contrast to other space related recording techniques, where the acoustic event is moved to the listener. When listening through high quality headphones it gives the illusion of being right at the scene of the acoustic events. ![]() It resembles the human head and has two microphone capsules built into the ears. The Neumann KU 100 Dummy Head Stereo Microphone is a binaural stereo microphone. It is highly recommended by some audio engineers for the rear channels. The Neumann KU 100 Dummy Head Stereo Microphone has its place, even in the age of surround sound. Neumann KU 100 Dummy Head Stereo Microphone
