Product Details

Overview
The Earthworks CTB30 tabletop boundary microphones are designed for permanent installation in ceilings and tabletops for conferencing and other speech applications.The Earthworks CTB30 boundary microphone is the perfect choice for high quality conferencing applications. 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. Additionally, it delivers an impressive reduction of unwanted sounds from paper shuffling.Measuring just 4.1 inches in diameter, the CTB30’s sleek design fits seamlessly into any room. It comes with a 10 ft (3.04m) low profile cable with XLR-3M attached, which is designed to exit from the side or bottom of the microphone. The XLR can be removed, allowing the cable to run through a small hole in the table surface for permanent installation. Two 6-32 screw holes and a keyhole are found on the bottom of the microphone for secure mounting, if required.
