Shure GLXD14RUK/SM31-Z2 Rackmount Vocal System


Shure's GLX-D Advanced Digital Wireless Headset System is the ideal solution for hands free vocals. Its brilliant for any public speaking scenario, be it a conference, presentation, or fitness class! 

SM31FH Condenser Microphone

A lightweight, low-profile design sits comfortably and securely on your head while you talk. Thanks to a flexible, gooseneck design, you can accurately position the mic to suit your preferences. A tailored frequency response will project your voice to your audience clearly and cleanly. 

An integrated piece of moisture-repellent hydrophobic fabric shields the mic against corrosion in more humid areas, while an included windscreen reduces possible plosives, wind and breath sound.  

GLXD1 Digital Wireless Bodypack Transmitter

Setup has been made incredibly simple here. The transmitter will link automatically with the receiver, leading to effortless frequency swapping. With an operating range of up to 30m and a battery life of 16 hours, you'll be able to perform without having to worry about your signal dropping out, or the system dying on you! 

GLXD4R Rack Mount Receiver

Detachable antennas allow for remote mounting (if this suits you better), while a durable, metal design ensures it'll withstand repeat, daily use. Additional features include a remote, adjustable transmitter gain control and an easy-to-read LCD screen.
