Description
Diffuse-field Frequency Altering Grid for 4003, 4006, 3503, 3506, 4051, 4052 and 4053 Microphones
From DPA, this Diffuse-field Grid mounts to the DPA 4003, 4006, 3503, 3506, 4051, 4052 and 4053 microphone capsules. The grid is a designed to provide a 6dB boost at 15kHz for better intelligibility and clarity at the high frequency spectrum.
The DD0297 is a microphone protection grid ideally suited for making all types of far-field recordings. It is supplied with 4003 and 4006, 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.
