The Earthworks IMBL Boundary Layer Microphones provide a pristine sounding microphone solution for permanent installations when keeping a low profile is of the utmost importance. Extended high frequency response to 30kHz and True Semisphere™ polar response allow those speaking to maintain the same intelligibility at the front and sides of the microphone without a loss of high frequencies. In addition, the extremely fast diaphragm settling time allows more subtle details of the human voice to be reproduced, which adds to the microphones' amazing clarity.

Primary applications include teleconferencing, distance learning, surveillance, boardrooms, government facilities, and ambient room miking.
