DPA APE50RS 50mm Acoustic Pressure EQ Ball for 4006A

DPA APE50RS 50mm Acoustic Pressure EQ Ball

DPA APE50RS 50mm Acoustic Pressure EQ Ball Details
The APE50 is a Ã?50 mm 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 offers a stronger on-axis boost and off-axis attenuation than the APE30 and APE40. Its larger dimensions accentuate the on-axis boost at lower frequencies and allow off-axis sources to be strongly attenuated above 1 kHz. This will give your recordings a more intense sensation of source clarity and presence, a marked increase in brightness, and extend the effective reach of your microphones.

You will also find that the APE50 is particular useful for making recordings under reverberant conditions.

This accessory substitutes the former L50B, suitable for 4003, 4006, 4006-TL and their stereo kits. The L50B 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.
