"The Shure BLX14R/SM35 brings multi-instrumentalists and live performers a cost-effective wireless headset microphone system with quality sound, simple setup, intuitive operation, and dependable performance right out of the box. It includes the rugged BLX4R single-channel receiver with LCD display, adjustable output level, and removable antennas for rackmounting the unit—ideal for sound-reinforcement applications in small venues, wedding halls, and houses of worship.
 
 The BLX14R/SM35 also includes an SM35 cardioid performance headset mic with collar clip and snap-fit windscreens, and a bodypack transmitter. The headset's wearable design offers both comfort and a secure fit for long-wearing use, and gives active performers the freedom to express themselves without having to sacrifice the sound quality found in traditional microphones.
 
 The receiver features one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. The system provides up to 14 hours of continuous use with two AA batteries, at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band."
