Shure BLX14R/MX53 — Wireless Rack-Mount Presenter System with MX153 Earset Microphone
BLX14R/MX53 Overview
The Shure BLX14R/MX53 is a complete wireless presenter system designed for houses of worship, corporate AV, broadcast, and live presentation environments. At its core is the BLX4R half-rack single-channel receiver, paired with the MX153 subminiature earset microphone and BLX1 bodypack transmitter, delivering professional-grade audio performance with minimal setup time. Operating on the J11 band (596–616 MHz), the system ships ready to deploy out of the box. This system is well suited for AV integrators, system installers, and audio engineers who need a reliable, rack-mountable wireless solution for spoken-word applications.
The half-rack form factor of the BLX4R integrates cleanly into standard equipment racks, and the included rackmount kit, dual 1/4-wave antennas, and all necessary accessories ensure a complete installation without additional procurement.
