An Electro-Voice Microphone Designed for Integration and Reliability
The Electro-Voice RE90B fits within the range of surface microphones used in fixed installations and events: a product designed to be visually unobtrusive while delivering consistent and controlled sound capture. Its approach is typical of solutions intended for spaces where speech must remain intelligible and stable (meeting rooms, places of worship, conferences), with a focus on operational robustness and reduction of unwanted noise and interference.
Who Is the RE90B For and In Which Applications Does It Excel?
This surface condenser microphone is particularly relevant if you are looking for a clean, understated, and easy-to-position solution for spoken voice. Placed on a conference table, reception desk, podium, lectern, or stage, it allows capturing speakers without requiring a handheld mic, boom, or visible gooseneck.
Thanks to its semi-cardioid directivity, the RE90B helps better control room ambiance compared to a more omnidirectional microphone, while maintaining smooth sound reproduction. It is suitable both for sound reinforcement applications and meeting recording systems, and integrates easily into microphone inventories for businesses, public institutions, schools, theaters, or technical service providers.
