IMB30/IMBL30

Common name: Earthworks Audio IMB30/IMBL30

Production Status: In production

The IMB30/IMBL30 Series boundary microphones are designed for permanent installation in ceilings and tabletops for conferencing and other speech applications. Optimised for speech, the IMB microphones feature a flat frequency response out to 30 kHz that delivers high level of speech intelligibility and articulation. The IMB microphone has near-perfect polar pattern across all frequencies. This wider coverage also means that fewer microphones are required to properly cover a conference room, cutting down on the number of channels of DSP, cables and other ancillary equipment required for the system. Compatible with all DSP systems that provide 24-48 V phantom power, the IMB microphones can easily integrate into existing system designs or new installations. Incorporating a unique filter that significantly reduces low frequency table thumping, HVAC noise and paper shuffling, the IMB microphones do not exhibit the problems common with conventional boundary microphones. The dual-color LumiComm™ light ring and touch sensor output found in the IMBL30 models allows integrators to program the microphone’s function and LED color, such as assigning a red LED colour for the microphone being muted. Designed with aesthetics in mind, the IMB microphones provide a discrete miking solution thanks to their diminutive size. The IMB30 microphone flange measures just over 1.4 inches (36.5 mm) wide and 0.125 inches (3.2 mm) tall. The IMBL30 LumiComm™ model flange measures just under 1.6 inches (40.5 mm) wide and 0.35 inches (8.8 mm) tall, mounting flush into the tabletop or ceiling for a low profile appearance. The IMB microphones are available with or without the LumiComm™ Touch Ring. Black, white and stainless finishes are available.
