A RE3 System Designed for Reliability on Stage and in Performance
The RE3-BPHW-8M follows a "system" approach: a discreet and precise headset microphone, a robust bodypack transmitter, and a receiver designed for easy integration into sound reinforcement. This product line logic ensures professional-grade features (metal housings, backlit LCD displays, antenna diversity on the reception side), with a coherent set aimed at consistent transmission and clear setting readability in real conditions.
Who It's For and What It's For: Speech, Shows, Classes, and Performances
This kit is intended for users who need a reliable hands-free microphone: speakers, trainers, actors, corporate presenters, places of worship, hosts, as well as coaches and teachers in classrooms. The headset frees the hands and stabilizes the mouth-to-microphone distance, which facilitates intelligibility and limits level variations during movement.
The supercardioid directivity helps better isolate the voice in noisy environments (monitors, close front-of-house, onstage music), while maintaining the detailed reproduction typical of a condenser capsule.
Key Features and Design: Efficiency, Control, and Integration
Headset Microphone: Precision and Comfort of Use
The RE3-ACC-HW3 features a pre-polarized condenser capsule, with an extended frequency response (30 Hz to 18 kHz) for detailed diction and natural presence. Its detachable cable (1150 mm) facilitates maintenance and fit adjustment, and the included windscreen helps reduce wind noise and certain plosive consonants during dynamic speech.
Bodypack Transmitter: Battery Life, Durability, Professional Connectivity
The RE3-BPT-8M transmitter operates in the 8M band (823 MHz to 865 MHz) and relies on a PLL frequency oscillator with 40 kHz ultrasonic synchronization. It includes a backlit LCD screen for quick control, a flexible external antenna, and a metal housing designed to withstand repeated handling (shows, tours, event performances).
The TA4F connector (Mini XLR 4-pin) ensures a reliable connection with the headset microphone. Power is supplied via 2 AA (LR6) 1.5 V batteries or a rechargeable NiMH battery, with charging contacts compatible with a dedicated charging base (sold separately).
Receiver: Antenna Diversity and Outputs Suitable for Sound Systems
The RE3-RX-8M receiver offers antenna diversity and a 36 MHz bandwidth, with a backlit LCD display for comfortable reading. On the audio side, it provides XLR and 6.35mm Jack outputs, convenient for integration both on a mixing console (mic or line input) and in a fixed system. The antennas are removable half-wave with BNC connectors, and DC power is provided for the antenna (12 V to 15 V / 100 mA).
