Hi Liron Linker, did you tried to update the firmware of the GLM module and both monitors as suggested ?
Fixes in GLM Version 4.1.1:
• Improvement to check for software/firmware updates. If any update is available, the notification message will be shown in the main page.
In case needed here is a copy of the fw-update procedure as mentioned into the release notes of GLM 4.1.1 aswell:
• The GLM adapter firmware update contains an improvement for the level handling when using the 9310 wired volume potentiometer. • The 9301A AES/EBU device firmware update improves the process of waking up from the sleep mode. Note: GLM will inform you if the firmware is already up-to-date, in which case an update is not needed. Firmware updates for SAM monitors, subwoofers and the GLM adapter Firmware updates are necessary to ensure that your SAM system can support all the features, continues to have the highest performance, and to make your system and calibration work better. Firmware updates may also be suggested by GLM for other products, if these products have not been updated earlier. Please see the instructions below to check if updates are available. The firmware update is started within GLM software, in the Info Feature. The steps required to check and update the firmware depend on whether you have previously run any system setups. Steps to apply firmware updates for users that have completed at least one system setup, which is now actively running.
• One at a time - right click on each monitor, subwoofer or network adapter icon in the GLM software main page and choose “Show Info” to open the info popup.
• See the Firmware Version info field. The update button is active if an update is available, then press the “Update” – button to update the firmware.
• Wait until the device is back online. This usually takes less than one minute.
• Repeat the process for all monitors on the GLM network. Steps to apply firmware updates for users that are setting up for the first time, and have not completed any system setup yet.
