Shure BLX14S31 K14 Headset Wireless Microphone System

Professional fitness instructors and performers can now own the stage with confidence using the BLX14/SM31 Headworn Wireless System, a precision-built solution that combines legendary Shure audio quality with simple setup. This comprehensive system operates on the K14 frequency band and includes everything needed for professional performance: the BLX4 wireless receiver, BLX1 bodypack transmitter, SM31 fitness headset microphone, power supply, clothing clip, windscreens, and user guide. The BLX® Wireless Systems family brings professional-quality sound with an intuitive interface that works right out of the box.

The durable BLX4 receiver features microprocessor-controlled internal antenna diversity with simple setup and intuitive controls, while the One-touch QuickScan frequency selection quickly locates the best open frequency when interference occurs. Both XLR and ¼" output connectors provide flexible connectivity options, complemented by a two-colour audio status indicator LED for clear operational feedback. The lightweight BLX1 bodypack transmitter offers ergonomic design with adjustable gain control and runs up to 14 hours continuously on just 2 AA batteries.

Built specifically for demanding fitness applications, the rugged SM31FH cardioid condenser microphone features hydrophobic materials that repel moisture and protect against corrosion damage that typically causes fitness headsets to fail. The wireframe design fits securely and comfortably during high-impact use, while the flexible gooseneck allows discrete adjustment for optimal placement and isolation. With its tailored frequency response for crisp vocal reproduction, TA4F connector compatibility with any Shure wireless bodypack, and included windscreen for clean sound, this system provides the reliability and performance that fitness and aerobics instructors demand.
