Shure Expert Technology

Those experts at Shure HQ have fitted this system with LINKFREQ frequency management. This delivers a pure and clear uninterrupted audio.

By constantly scanning the available frequencies, it automatically selects the best open channel. And if BlueTooth or WIFI get in the way it'll easily find another channel. This all happens while it's working and you won't hear any change in audio as it does so!

Furthermore, you can even have eight GLX-D Systems running at the same time. Easily increase your wireless setup when you wish to.

Lithium-ion battery that's fully rechargeable

All GLX-D transmitters come with a rechargeable lithium-ion battery. And so you know how much charge you have, the high-resolution screen shows how much juice is left in the battery.

Offering you complete confidence in the Shure GLXD14/SM31 Wireless System.

A full battery charge will give you 16 continuous hours. And in an emergency, a 15-minute quick-charge delivers an hour and a half!
