Update all GLX-D devices in a configuration to the same firmware version


  • Single User Group: A single user can find the best possible frequencies through a new group named Group 4, which transmits on three frequencies, like all other groups, but has 27 backups to provide the system with the ultimate flexibility for a single user in harsh environments.


  • Scanning Accuracy: The receiver more accurately models the RF environment and chooses the best starting point when you select the Channel button to scan or the Group button to choose a new group.  As with the previous firmware version, the system will continue to adjust as needed within that particular channel on any group with backup frequencies.  Note that you may notice the scan takes slightly longer than with previous firmware versions.
  • Improved audio stability in marginal RF conditions.


  • GLX-D devices on firmware version or higher are not compatible with earlier versions. Ensure all GLX-D devices in a configuration have the same firmware version. 
  • For operation of GLX-D devices with other Shure networked systems, see the following list of minimum firmware versions that are supported with GLX-D version
    • Shure Update Utility 2.2.1
