New 4088 Cardioid Headset Mic from DPA
 October 29, 2004
DPA Microphones debuted its new cardioid headband microphone, the DPA 4088, at the AES show in San Francisco. The 4088 is intended for live performances requiring high stage volumes.
The capsule is a pre-polarized first order pressure gradient transducer, hidden in a small and lightweight housing with dimensions just slightly larger than our omni capsules. The low frequency response is designed for optimal linearity at 1 to 1.5 inches distance from the sound source. The result is a bass roll-off that will be relatively prominent at a small distance (in practice no response under 1kHz at only 20 inches). This is paramount when it comes to rejection of background noise and the fight for avoiding feedback. The 4088 offers a large amount of gain before feedback without losing its clarity and definition according to the company.
The mechanical design is based on the 4066 headband microphone. The headband mount is exactly the same; the boom however is 3 centimeters longer, to be able to match the need for placement at the corner of the mouth. To avoid "popping", the element should not be put directly in front of the mouth. The sound timbre and sound pressure level is as good at the side of the mouth as it is in the front. The flexibility and stability of this construction is unique and has no equal.
