CAD Audio CAD Astatic 220VP Variable Polar Pattern Installation Boundary Button Microphone

The 220VP is a button-style boundary microphone for permanent installation on tabletops, podiums or walls, with a continuously-variable polar pattern that an installer can set to match the room. Its threaded metal body mounts through surfaces up to 3 inches thick, and shock-absorbing bushings cut down on handling and vibration noise.

A built-in 80 Hz high-pass filter (12 dB/octave) rolls off table thumps and HVAC rumble before they reach the mixer, and RF-resistant construction keeps it clean near wireless gear and lighting dimmers common in conference rooms.
