Description

The KU 100 dummy head is a binaural stereo microphone. It resembles the human head and has two microphone capsules built into the ears. When listening through high-quality headphones it gives the illusion of being right at the scene of the acoustic events. 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. The dummy head is also used in many industrial applications as a measuring device, for example in acoustic research. 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. At the bottom of the unit is a switch for the different power supply modes, as well as connectors for balanced and unbalanced output signals. Inside the head are additional switches for 10 dB attenuation and the high-pass filter.

Features
