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.
