The DPA BLM4060 Boundary Layer Microphone 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 centre 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.

Key Features:

Hemispherical Omnidirectional Pattern

The hemispherical omnidirectional polar pattern effectively captures talkers seated around the microphone while rejecting reflections of the table surface.

Excellent Speech Capturing

The frequency response is optimised for greater intelligibility of speech.

Handsome Low Profile Design

The BLM4060 features a stainless steel base and rubber centre which holds the capsule and effectively absorbs shock and vibration noise.
