collapse expand iconDescription

The BLX14 configuration includes the BLX4 single-channel receiver, BLX1 bodypack transmitter, and the SM31FH headset microphone. This kit also includes power supply, headset windscreens, and user guide. Shure BLX Wireless Systems combine professional-quality sound with simple setup and an intuitive interface for legendary audio performance right out of the box. It is an ideal combination for exercise instructors. It is usable for many other applications, but the attributes of the SM31FH make it ideal for exercise environments.

Choose from one of four bandwidths:
H9: 512–542mHz
H10: 542–572mHz
H11: 572–596mHz
J11: 596–616mHz

BLX1
The BLX series bodypack transmitter works with lavalier and headset microphones. With the WA302 1/4" to TA4F cable, it also works for electric guitar or bass. The beltpack features an On/Off hard toggle switch, preferring to eliminate the multi-function push button that is used on some wireless transmitters. Many users found the multi-function single button to be inconvenient and unreliable.It additionally features continuously adjustable gain, a single bi-color LED for battery status, and a rugged ABS polymer body. It operates on two AA batteries for up to 14 hours of battery life. Its sleek, side taper design makes it a comfortable fit on your belt.

BLX4
The durable BLX4 features simple setup, intuitive controls, and microprocessor-controlled internal antenna diversity. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference.

SM31FH
Cardioid condenser headset microphone for wireless systems features hydrophobic construction that repels moisture. For use in fitness instruction.

    I just received this mic today for my fitness studio. One of my instructors attempted to use it and to say the sound quality was poor, would be an overstatement. This mic is horrible! The sound is muffled and you can barely understand what the person is saying. I will returning all four, tomorrow.
