Path of Miracles - HEIGHT

Height Left and Right (DPA 4006)

The Height Left and Height Right microphones were placed in the same lateral position as the A and B microphones of the Decca Tree but were raised one meter higher. In order to obtain information for the current standard of multichannel reproduction (7.1.4), acoustic information from above the listening position is captured in order to offer a more complete and immersive experience of the performance. This information must be perceptually decorrelated from the main image and contain more reverberant and less direct sound, otherwise the listener may find that the entire ensemble now sounds as though they are singing in the rafters.  The DPA 4006 microphone is a small-diaphragm condensor with an exceptionally flat frequency response. Originally developed by B&K as a measurement microphone, the 4006's omnidirectional pickup pattern stems from its fixed pressure capsule. Omnidirectional microphones are more sensitive to low frequencies than directional microphones, making them the most complete single-point capsule. Not only is the DPA 4006 favoured by classical engineers on Earth, NASA's Perseverance rover was equipped with a 4006 on its 2020 mission, making it the favourite microphone on Mars.
