The Shure BLX4R is a single-channel wireless receiver compatible with the BLX1 bodypack transmitter and BLX2 handheld transmitters. It features a rugged metal chassis and, using the included hardware, can be rackmounted with the two removable antennas positioned on the front of the rack—for optimal signal reception in A/V installations and sound-reinforcement applications.

The BLX4R offers one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. It also employs microprocessor-controlled diversity technology to reduce dropouts. BLX systems allow up to 12 mic channels to operate simultaneously in each frequency band, at a range up to 300'.

The LCD display shows group and channel settings, and allows you to meter audio level and signal strength. An LED indicator even lets you keep an eye on the transmitter's remaining battery life. The unit offers 1/4" and XLR connectors with adjustable output level for flexible connectivity to PA systems and mixing boards.
