Product Description
The rugged and durable SM31FH is a cardioid condenser microphone constructed with hydrophobic materials that make it ideal for true performance in fitness instruction applications. The moisture-repellent cartridge housing ensures a long product life by protecting the microphone from the corrosion damage that causes typical fitness instruction headsets to fail. The SM31FH features TA4F 4-pin (TQG) connectors that make it a viable replacement for any Shure wireless headset system. \n \nWearable wireframe headset with secure, comfortable fit made for fitness and aerobics instructors \nIntegrated moisture-repelling fabric protects the microphone element from harmful corrosion for use in humid environments \nFlexible gooseneck design provides discrete adjustment options to optimize placement for greatest isolation \nLightweight and low-profile form factors stave off fatigue during high-impact use \nCompatible with Shure wireless bodypack systems for direct replacement of TA4F-connected microphones \nAvailable with a wide variety of Shure wireless systems, renowned for their ease of use and reliable performance \nIncluded windscreen tames plosive, breath and wind noise for clean and intelligble sound \nTailored frequency response refined for crisp and clear vocal reproduction \nLegendary Shure precision engineering for durability and performance
\n \nConsumer Alert:
\nMost users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC's wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones. \nFeatures
