The Electro-Voice RE92TX is a professional cardioid lavalier lapel microphone designed to provide clear, intelligible voice capture for broadcast, theater, corporate presentation, and public speaking applications where a discreet, hands-free solution is required. Its miniature condenser capsule is engineered with a tailored cardioid polar pattern, which focuses on sound arriving from the front while providing significant rejection of ambient noise and room acoustics from the sides and rear. This directional sensitivity is crucial for minimizing feedback and isolating the speaker's voice in challenging acoustic environments, ensuring that speech remains the primary audio source picked up by the system.

Encased in a durable and compact metal housing, the microphone is built to withstand the rigors of daily professional use and is often paired with a professional wireless transmitter via a standard 3-pin mini-XLR connector. The package typically includes a range of mounting accessories such as alligator clips, tie-clips, and windscreens to facilitate secure and optimal placement on clothing, whether for a business suit, theatrical costume, or casual attire. Its design prioritizes both inconspicuous visibility on camera and consistent audio performance, with a frequency response shaped to enhance vocal presence and clarity while controlling plosives and handling noise.

Integrating this lavalier into a wireless or wired system provides presenters and performers with the freedom of movement and the assurance of reliable audio capture. The microphone's ability to deliver a clean, focused signal directly from the sound source makes it an indispensable tool for audio engineers in live events, television production, and installed conferencing systems. By combining discreet form factor with professional-grade acoustic performance, the RE92TX offers a reliable and effective solution for critical speech reinforcement where visual subtlety and audio fidelity are equally important.
