Electrovoice RE90BW

A Microphone Designed for Installation: The RE90 Philosophy

The Electro-Voice RE90BW fits into the brand's "installation" approach: microphones designed to operate reliably daily in venues where consistency, visual discretion, and stable intelligibility are paramount. The "boundary microphone" format addresses a very practical need: effective capture without multiplying microphone stands, without obscuring speakers, and without complicating setup. With its white finish, the RE90BW naturally integrates into light environments (white tables, illuminated lecterns, places of worship, corporate spaces) while maintaining an almost invisible presence on camera.

Who Is It For and What Are Its Uses?

This microphone is intended for integrators, stage managers, and technical managers who need to amplify speaking spaces with a clean sound and neat installation. On a conference table or desk, it captures voices with good clarity without cluttering the visual field or disrupting document handling. On a lectern, altar, or stage, it provides a discreet capture solution when avoiding a conspicuous boom microphone is desired.

Thanks to its ability to handle high SPL levels, it can also be relevant in contexts where the source is very close to the microphone or becomes more powerful (dynamic speech, close ambiance). Its high dynamic range helps maintain headroom during operation, facilitating console adjustment and consistent sound levels in the room.

Designed for Reliable and Clean Daily Capture

RF Shield Technology: More Confidence Against Interference

In modern environments, the proliferation of transmitters (phones, networks, IT equipment) can cause unwanted noise or unstable behavior. The exclusive RF Shield technology of the RE90BW aims to better protect the capture from these disturbances. The result: more reliable use in conference rooms, event spaces, schools, or places of worship, where the devices around the microphone are not always controlled.

A Voice-Optimized Balance

With a frequency response of 80 Hz to 15 kHz, the RE90BW favors a reproduction useful for speech: enough low-mid frequencies to provide presence, and a high spectrum that preserves articulation. The specified self-noise (< 25 dB SPL A-weighted ) contributes to a cleaner sound when gain must be increased, typically in quieter speech or very silent environments.

Simple Integration into Audio Systems

The RE90BW operates with phantom power from 9 to 52 V, making it compatible with most consoles, interfaces, and installed sound systems that supply phantom power. Its output impedance of 200 Ohms facilitates integration on standard microphone inputs. Its compact format and white color allow discreet placement while remaining robust for permanent installations.
