Earthworks IMB30 Overview

The black IMB30B High-Definition Boundary Microphone by Earthworks is for capturing audio. It is used in fixed sound installations for audio applications such as teleconferencing, surveillance, boardrooms, government facilities, lecture halls, and more. The IMB series can be custom mounted on a table and provides great sound quality, flexibility, and ease of installation.

The IMB30B features an omni semisphere polar pattern and has a frequency response of 60 Hz to 30 kHz. The microphone is powered by 48V phantom power and terminates in a XLR3M connector.

This mic features a uniform frequency response at 0, 45, and 90°. This semisphere polar response allows the use of fewer microphones, while obtaining higher intelligibility. In addition, you also have more sound level before feedback, no spotlighting or highlighting, and more rejection of sounds from the rear of the microphone. The IML series provides a low profile, pristine sounding microphone solution for permanent installations. A lock nut is included.
