The DPA L40B is a Ø40 mm sphere shaped Acoustic Pressure Equaliser, designed for use with the DPA Standard Microphone Type 4003 and 4006 or the A-B Stereo Kits Type 3529-A and 3530-A. It offers a more noticeable on-axis boost between 2 and 8 kHz, and a stronger off-axis attenuation than the L30B. This gives a marked increase in the directivity of your recordings (at 4 kHz, the front-to-back sensitivity ratio is 8 dB), and decreases the effects of reverberation and off-axis sources. When using L40B, you can modify the spectral characteristic of a source by simply altering the angle of incidence to give a frequency boost, a flat response or an attenuation.
