The BLM4060 from DPA is a professional boundary layer microphone designed to pickup speech in meetings, interviews, conferences and other discussion capturing applications. The microphone element features a hemispherical omnidirectional polar pattern for excellent diffuse (reflected) sound field rejection, off the mounted surface.

The omnidirectional polar pattern provides a uniform frequency and sensitivity response at the perimeter of the capsule, allowing talkers to speak freely from any position in relationship to the microphone placement.
The handsome BLM4060 features a stainless steel base and rubber, shock-absorbing center that effectively mounts the capsule and eliminates vibration noise. The BLM4060 delivers incredible sound and is a great looking addition to any boardroom, courtroom, broadcast studio, etc.
