More Info
Due to government regulations some wireless products will not work in certain areas. If you are unsure whether a product will work in your area, please purchase a digital wireless system (which should work in almost all areas) or contact us for more information.

The BLX14/SM31 Headworn Wireless System brings professional-grade audio performance to fitness instructors and performers who demand reliability in challenging environments. Operating on the M17 frequency band, this comprehensive wireless solution combines the BLX4R receiver, BLX1 bodypack transmitter, and the specialised SM31 fitness headset microphone. The system includes everything needed for immediate deployment: power supply, clothing clip, windscreens, and user guide.

Built for durability and ease of use, the rack-mountable BLX4R receiver features rugged metal construction with XLR and �" output connectors. Its one-touch QuickScan frequency selection automatically locates the clearest available frequency when interference occurs, while the LCD display provides detailed RF and audio metering. The lightweight BLX1 bodypack transmitter offers up to 14 hours of continuous operation on two AA batteries, with adjustable gain control and quick receiver frequency matching capabilities.

The SM31FH headset microphone stands apart with its moisture-repellent hydrophobic materials, specifically engineered to withstand the humid conditions that typically destroy fitness instruction headsets. The cardioid condenser capsule delivers tailored frequency response for crisp vocal reproduction, while the flexible gooseneck allows discrete positioning for optimal isolation. Its wireframe design ensures secure, comfortable fit during high-impact activities, and the TA4F connector maintains compatibility with all Shure wireless bodypack systems.
