Earthworks CTB30

Earthworks is now shipping the CTB30 boundary microphone. Designed for conferencing and speech applications, the CTB30 claims exceptional speech intelligibility and coverage coupled with a low profile appearance for conference rooms, boardrooms, classrooms, lecterns, and houses of worship. The CTB30 features a flat frequency response from 60Hz to 30kHz and a fast diaphragm settling time that allows more subtle details of the human voice to be reproduced. Its True Semisphere polar response provides an omni semisphere of coverage and delivers the same high intelligibility of each orator speaking around the microphone without loss of high frequencies. The wide and even coverage across the microphone’s pickup pattern means that just one CTB30 can provide excellent coverage for a 12ft. conference table that seats up to 12 people.
