The BLX14R/SM35 Headworn Wireless System from Shure includes a BLX4R single-channel rackmount wireless receiver, a BLX1 bodypack transmitter, and an SM35 headset condenser microphone. The system is set to Shure's K12 frequency band and operates between 614 - 638 MHZ.
The BXL1 bodypack transmitter has a 300' line of sight operation range with the BLX4R receiver. It is powered by two included AA batteries that can provide up to 14 hours of operation. The BLX4R receiver features microprocessor-controlled internal antenna diversity that helps prevent interference and signal dropouts. Its one-touch QuickScan feature detects the most interference-free frequency and sets the channel to it for fast setup.
