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.

great for what im doing. maybe not as good in a vehicle though
Size: 36 sqft
decent product. not as thick as typical sound deadening but definitely cheaper. and for my application, i didnt need a name brand thicker material. i am putting it on our heat and ac vent and intake pipes during our remodel. sound travels from room to room in our old house through these vents and pipes so a little sound deadening goes a long way

Buy the individual cross cut sheets, not these rolls.
Size: 36 sqft
I ordered two different types, individually cross cut foil rectangular pieces and these rolls both containing 36. sq. ft. The cross cut sheet blows this away. This stuff is much thinner, much less butyl rubber, much flimsier foil, and needs twice as much to have the same effect. Once you put it on, you cant remove it. The other brand's 2mm is much thicker than this.
