Boundary Condenser Button Microphone

Boundary Condenser Button Microphone

<p>The Astatic B205 M is a compact boundary condenser microphone designed for clear, intelligible sound capture in conference rooms, classrooms, boardrooms, video conferencing spaces, and installed recording environments. Utilizing a subcardioid polar pattern, the B205 M delivers focused pickup while reducing ambient room noise and reflections, making it ideal for tabletop or surface mounted applications where consistent speech clarity is required. Its low profile, lightweight design allows discreet placement without visual clutter, supporting professional AV installations where aesthetics matter.</p>

<p>Equipped with a back electret condenser element, the B205 M offers a smooth, natural frequency response and high SPL handling for both speech and live sound reinforcement. A wide dynamic range and low noise floor ensure accurate audio reproduction, while phantom powered operation (9–52 V) allows compatibility with a broad range of mixers, DSPs, and conferencing systems. With professional 3 pin XLR connectivity and rugged construction, the B205 M is well suited for fixed installations and portable applications alike.</p>
