Shure BLX14R/MX53 Wireless Rack-Mount Presenter System

The BLX14R/MX53 puts a subminiature MX153 earset microphone on a BLX1 bodypack transmitter and receives it on the BLX4R half-rack receiver, a set-up for presenters, worship leaders and stage talent who need their hands free. The BLX4R mounts in a rack with the included kit, uses two detachable quarter-wave antennas, and shows status on its LCD. QuickScan picks an open frequency.

All four US frequency bands are listed in the picker and carry the same price. Choose the band that is open where you work; receiver and transmitter in this kit already match. The BLX transmitter runs up to 14 hours on a pair of AA batteries, and up to 12 BLX systems can share one band where conditions allow.
