The Earthworks CTB30 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 at various distances from the microphone.
The CTB30 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 is completely immune to RF interference from mobile phones and other RF sources. Measuring just 4.1 inches in diameter, the CTB30’s sleek design fits seamlessly into any room.
