The Earthworks IMB & IMBL Boundary Installation Microphones, designed for permanent installation, are now shipping. The IMBL30 comes in a black, white or silver finish and features the all new LumiComm Touch Ring, which consists of a dual-color LED light ring and a touch sensor output, providing integrators complete freedom to assign function and LED color with a media control system. And the Earthworks Boundary Microphones feature RF shielding to prevent interference from cell phones and other electronic devices.

IMB30 models are available without the LumiComm Touch Ring, and come in a black, white or silver finish. The IMB microphones are only 1.44″ (3.6 centimeters) in diameter and the IMBL models have a 1.59″ (4.0 centimeters) diameter and feature a 60Hz to 30kHz ±2dB frequency response, and claim the flattest frequency response of any boundary microphone on the market. Coupled with a True Semisphere polar pattern, which features a near-perfect frequency response at 0, 45 and 90 degrees, the IMB and IMBL microphones deliver exceptional clarity and intelligibility for fixed installations.

The IMB and IMBL Boundary Microphones have a max acoustic input of 136dB SPL and sensitivity of 70mV/Pa. This near-perfect polar response and high sensitivity allow a sound contractor to install fewer IMB microphones and cover the room with full frequency response.
