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.

Such a disappointment!
Too much oil, the flesh is too watery and too salty with unpleasant smell. Dismal!

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
