FEATURES

• Acoustically modifies the sound of Schoeps omni transducers
• Two sizes, which slip over the capsule and front end of the microphone body

These ball-shaped accessories slip over the head of the pressure (omni) transducers, as shown in the photograph. The KA 40 has a diameter of 40 mm, the KA 50 of 50 mm. They alter the sonic character of the microphone acoustically, as is evident by comparing the graphs of the CMC 62 (CMC 6 with MK 2) with and without the KAs. With the 40 mm sphere, the normally ruler-flat on-axis frequency response curve of the MK 2 is emphasized slightly (max. +2 dB) in the region between 1 kHz and 9 kHz. This effect is stronger still with the 50 mm sphere (max. +3 dB). This is not due to any change in directionality, as is sometimes supposed, but rather to the elevated response plateau which is achieved without sacrificing bass response.

Some engineers prefer to achieve this effect by using KAs instead of an equalizer.
