The Earthworks CTB30-B High Definition Boundary Microphone is the perfect choice for high quality teleconferencing applications. It is a low profile, pristine sounding microphone solution for any conference or huddle space. Its extended high frequency response to 30kHz and Omni Semisphere polar response provide the same high intelligibility at virtually any point around a conference table or other surface on which the microphone is mounted. In addition, the extremely fast diaphragm settling time allows more subtle details and nuances of the human voice to be reproduced, which adds to the incredible clarity and intelligibility of the CTB30-B at various distances from the microphone.

The CTB30-B incorporates a unique filter that significantly reduces low frequency table thumping and HVAC noise. In addition, it delivers an impressive reduction of unwanted sounds from paper and pens. Like all Earthworks microphones, the CTB30-B is completely immune to RF interference from mobile phones and other RF sources. Measuring just 4.1 inches in diameter, the sleek design of the CTB30-B fits seamlessly into any room.

Did You Know...... that while boundary mics are widely utilized in conference rooms and training applications many Audio Engineers use them as drum recording mics. It's true! Musicians and Audio Engineers can benefit from a pair of boundary mics by placing them on the floor on both sides of a kick drum, on the walls or even inside the kick drum. Have fun experimenting to find your killer drum sound.
