The Telex RE97Tx is a professional, micro-headworn condenser microphone system designed for discreet, high-performance voice capture in live sound, broadcast, and theatrical applications. It consists of an extremely small condenser microphone capsule attached to a thin, flexible wire boom, which is designed to be worn around the ear, positioning the capsule consistently just off the corner of the user's mouth. This design offers a nearly invisible profile on stage or camera while providing superior audio quality and excellent rejection of ambient noise compared to traditional lavalier microphones. The system is complete with a bodypack transmitter (as indicated by the "Tx" suffix), creating a fully integrated wireless microphone solution ready for use with compatible Telex and other UHF receiver systems.

The microphone capsule itself is an electric condenser design, requiring bias voltage (plug-in power) from the attached bodypack transmitter. Its ultra-small size and precise placement near the mouth result in a clear, present sound with strong proximity effect, enhancing vocal warmth and intelligibility. The microphone's omnidirectional polar pattern is effectively leveraged by its consistent positioning, allowing it to capture the direct voice signal robustly while minimizing off-axis noise. The thin, flesh-toned wire boom is highly flexible and memory-retentive, enabling a custom, secure fit for each user that remains stable during movement, making it ideal for active presenters, vocalists, and actors.

The included bodypack transmitter is a compact, robust unit typically operating in the UHF band, featuring professional-grade components for stable, low-noise transmission. It provides the necessary phantom power to the microphone capsule, houses the audio processing circuitry (including pre-emphasis and compression), and features controls for power, frequency selection, and audio gain. The complete RE97Tx system balances critical factors of audio quality, physical discretion, and reliable wireless performance, making it a preferred choice for applications where both sonic fidelity and a clean visual appearance are paramount, such as television broadcasts, major theatrical productions, and high-profile live events.
