DPA d:screet BLM4060 Boundary Layer Microphone
The DPA BLM4060 is a boundary layer microphone system consisting of a miniature DPA 4060 omni-directional mic capsule and DAD6001 adapter. It’s ideal for use in boardrooms, conferences, courtrooms, teleconferencing and other settings where wide vocal pick up is required.
The mic works perfectly when mounted on tables, but also works well attached to any flat surface, including walls. Picking up sound from all directions thanks to its omni-directional polar pattern, no matter where the mic is placed in the room, you’ll still capture clear and consistent sound.
