Earthworks IMBL30 Omni Semisphere Boundary Layer Microphone with LumiComm Touch Ring for Conference Rooms and Fixed Sound Installations,60Hz to 30kHz, White

Earthworks IMB & IMBL Series Boundary Layer Microphones
The IMB & IMBL boundary microphones provide a low profile, pristine sounding microphone solution for permanent sound installations. The 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 amazing clarity and intelligibility of these microphones. A prominent feature of the IMBL microphones is the LumiComm LED Touch Ring (with dual color LEDs in red & green) that is touch sensitive and can be used to turn the microphone either on or off or any other programmed function, simply by touching the light ring. The IMBL system interface board will allow the touch ring to be programmed by standard system interfaces or logic control systems. The IMBL system interface board is powered from an external power source of 8 to 28VDC @ 85-170 mA (current is dependent upon number of LEDs illuminated at one time). The IMB and IMBL Boundary High Definition Microphones will provide exceptional sound quality, with very high intelligibility at virtually all angles and distances.

High Definition Boundary Microphones for Fixed Installations
The Earthworks IMB & IMBL Series High Definition Boundary Microphones are the perfect choice for high quality sound system installations. The extended high frequency response, fast diaphragm settling time and near-perfect polar response all work together to provide the highest performance boundary microphones. The IMB & IMBL Series provides you with the perfect low profile solution for conference rooms and a variety of sound installations, while providing the ultimate in sound quality.

Near-Perfect Polar Response
David Blackmer, founder of dbx and Earthworks invented a number of new microphone technologies resulting in a totally new approach to microphone design. One such technology was the creation of near-perfect polar response. When you look at the polar response of an Earthworks microphone, the mid-frequencies, high-frequencies and low-frequencies all look very close to a "textbook" perfect polar pattern. In practice this means the polar response of an Earthworks microphone is extremely uniform over its operating frequency range; the frequency response at 90deg. and 180deg. off-axis is very close to the on-axis response. This uniform polar response results in less phase problems and much higher intelligibility at the sides of the microphone.
