About Shure BLX14R/W93

The Shure BLX14R/W93 Rackable Lavalier Wireless System (H8: 518 - 542 MHz) includes a BLX1 bodypack transmitter, a BLX4R single-channel rackmountable receiver and a WL93 subminiature lavalier microphone. It can be used when a highly visible mic is not desired such as in theater, television, broadcasting and film applications.

The BLX4R receiver has a front-panel dual-color LED status indicator that glows green for normal levels and red when clipping for fast metering. It has both an XLR and 1/4" instrument output for connecting your instrument to a variety of equipment such as mixing boards or PA systems. The one-touch Quick-Scan feature automatically tunes the receiver to the clearest channel available and displays it on the front-panel LCD screen to allow you to tune the transmitter. The unit can be rackmounted with the included rackmount kit. The BLX1 is powered by two included AA batteries for up to 14 hours. The system has a 300' line of sight range of operation.

The WL93 lavalier mic has an omnidirectional polar pattern and comes with a mounting block attached to a tie bar as well as a sew-on mounting bracket.
