How can I update the firmware of my devices in GLM 4.x ?
After the installation of the recent version of GLM you always should make sure that the firmware of your GLM network adapter, speakers and the subwoofers is up-to-date. Here is how you do it: Select "Info" in the lower left corner of GLM's main window and click on the icons of your network adapter, speakers and the subwoofers to open their info-panels. Here you can see the firmware status and start the update-process if needed. We recommend to re-calibrate your system after the updates.
