Product overview
The SCHOEPS KA 40 is a 40 mm sphere attachment for the omnidirectional MK 2, MK 2H and MK 2S, recommended for the Decca tree.
The sphere is simply plugged on the microphone. As an acoustic filter it gives greater off-axis shadowing at medium frequencies, producing an increased directivity between 1 and 4 kHz; before good pressure-gradient microphones existed, this was the classic way to obtain directivity.
The KA 40 creates the impression of a closer placement. Its higher directivity is also an advantage in the Decca tree, because it creates some level differences in what is otherwise a purely time-of-arrival-based stereo technique. It is part of the SCHOEPS Decca Tree Set.
