The Acoustic Pressure Equalizer Ball for d:dicate™ 4006A Omnidirectional Microphone is a sphere shaped Acoustic Pressure Equalizer. It comes in three sizes and can be used for the microphone or the stereo kit.
The Acoustic Pressure Equalizers – APEs – are passive acoustic processors functioning as both spatial and spectral modifiers. They use surface diffractions to modify the sound field near the microphone diaphragm. This technique is only possible on omnidirectional pressure microphones.
Two primary changes occur when using APEs. The first is an upper-midrange/high frequency boost (without changing the low end). This is due to the pressure build-up at certain frequencies depending on the element’s size. And the second is more directionality at higher frequencies (focus).
A presence (upper-midrange) lift is often desirable in rhythmical genres, to make a voice or an instrument cut through a mix or simply to make it more intelligible or well defined. For symphonic music, the frequency response of certain legendary vintage types of microphones can be obtained using an APE. However, you will achieve a much higher degree of naturalness and detail when using a precision-handcrafted d:dicate™ 4006A Omnidirectional Microphone.
