A microphone protection grid suited for making all types of far-field recordings.
The grid is supplied with d:dicate™ 4003 Omnidirectional Microphone, 130 V and d:dicate™ 4006 Omnidirectional Microphone, but can also be ordered separately. With this grid fitted, your microphone will achieve a linear diffuse-field response up to 15 kHz.
In the near-field, the on-axis response has a 6 dB boost at 15 kHz. At intermediate distances, you can orient your microphone at a "grazing angle" of incidence to the sound source to give a normal response to direct sound while brightening up reflective sound.
