Shure GLXD4 Digital Wireless Receiver

Full Description

Please Note: The Shure GLXD4UK receiver requires no license to use, as it operates in the globally license-free 2.4 GHz frequency band.

LINKFREQ Automatic Frequency Management

The Shure GLXD4UK Wireless Receiver features the LINKFREQ Automatic Frequency Management system, greatly improving signal stability. This system works by continuously scanning the available frequency spectrum and automatically selecting the best open channel, with no audio interruption. Combined with its true diversity operation, which compares and selects the strongest signal from the device's two independent antennae, this system ensures that the receiver always delivers consistent, crystal-clear audio.
