CAD Audio CAD Astatic B205-M Boundary Condenser Button Microphone
The B205-M is a back-electret condenser boundary microphone in a low-profile button housing, built for tabletop and surface-mount installation in conference and meeting rooms. Its subcardioid pattern gives it wider pickup than a directional boundary mic, useful when several people sit around the same table.
It accepts a wide 9-52V phantom power range, which makes it compatible with more mixer and paging inputs than mics that require a full 48V, and its 3-pin XLR output wires straight into standard audio equipment.
