Nuanced vocals. Authentic sound.
BOUNDARY MICROPHONE
IMB30 & IMBL30
Pristine Speech. Discrete Look.
Clarity When It’s Critical
Optimized for speech, the IMB boundary microphones are the most reliable omnidirectional miking solution.Â

Public Speaking With No Struggles
The IMB microphones feature a flat frequency response out to 30kHz that delivers the highest level of speech intelligibility and articulation.

Conferencing, Made Simple
A near-perfect polar pattern means wider coverage. Wider coverage means fewer mics and cables.

Construction
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 (36.5mm) wide and 0.125 inches (3.2mm) tall. The IMBL30 LumiCommâ„¢ model flange measures just under 1.6 inches (40.5mm) wide and 0.35 inches (8.8mm) tall, mounting flush into the tabletop or ceiling for a low profile appearance.
Options
The IMB microphones are available with or without the LumiCommâ„¢ Touch Ring. Black, white and stainless finishes are available.
