DPA APE30RS 30mm Acoustic Pressure EQ Ball

DPA APE30RS 30mm Acoustic Pressure EQ Ball Details
The APE30 is a 30mm sphere shaped Acoustic Pressure Equalizer, designed for use with the Reference Standard Microphone 4006A or the ST4006A stereo kit. For use with the compact 4006C, the microphone must be either hung or placed in the clip with an XLR connector plugged in.

It gives a mild modification of your microphone's on-axis and off-axis frequency responses, and a slight change in the direction-to-reverberation ratio. This will give your recordings greater presence, nearness and clarity on-axis (especially around 4 kHz). An on-axis boost, between 2 and 8 kHz, and high-frequency roll-off off-axis, will sometimes help you capture the subtle audible details of both musical instruments and voices.

This accessory substitutes the former L30B, suitable for 4003, 4006, 4006-TL and their stereo kits. The L30B cannot be used with the modular series 4006A or 4006C and vice versa.

More on acoustic modification
The Acoustic Pressure Equalizers â" APEs â" are passive acoustic processors functioning as both spatial and spectral modifiers. They use diffractions on the surface to modify the sound field near the microphone diaphragm. This technique is only possible on omnidirectional pressure microphones.

Two primary changes occur:
  1. An upper-midrange/high frequency boost (without changing the low end) due to the pressure build-up at certain frequencies depending on the elementâ?s size.
  2. 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 one of the APEs. However, you will achieve a much higher degree of naturalness and detail when using a precision handcrafted 4006A.
