About Shure BLX14R/W85

The Shure BLX14R/W85 Rackable Lavalier Wireless System (K12: 614-638 MHz) includes a BLX1 bodypack transmitter, a BLX4R single-channel rackmountable receiver, a WL183 omnidirectional lavalier microphone, a WL184 supercardioid lavalier microphone and a WL185 cardioid lavalier microphone.

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.

While the system has one channel, it includes a WL183 omnidirectional lavalier mic, a WL184 supercarioid lavalier mic and a WL185 cardioid lavalier for you to select from based on your miking needs. They each have a tie clip that can be rotated in 90deg. intervals for flexibility in placement.
