How to Update GLD System Firmware
Note 1: Use a USB key with at least 40 MB of free space. Delete any existing GLD Firmware on the key
as described below.
Note 2: The firmware file transfer must not be interrupted. Failure to complete the transfer may result
in firmware corruption of the GLD. Make sure the mains power and connecting cables are reliable and that
the system will not be disturbed or switched off during the update.
Note 3: Updating firmware restores the console parameters to factory default. If you want to keep
your current settings then go to the Setup / Memory / Show Manager screen and store them as a Show
memory before starting the update. Recall the show after you have updated your firmware.
Note 4: After updating the firmware you may need to re-calibrate the touch screen and faders. Do this
using the Setup / Utility / Calibration screen.
Firmware update instructions for Windows:
Step1 Download the firmware
Visit www.allen-heath.com and download the latest GLD firmware. Save the zipped file to your
Desktop or folder of your choice. You may also wish to keep a copy of this zip file as a backup of
this version of firmware.
Step2 Remove any previous GLD Firmware from your USB key
Plug a USB key into your computer. If you have previous GLD firmware already on your key, look
in its AllenHeathGLD folder and delete the existing Firmware directory and also the
Firmware.md5 file in the AllenHeathGLD folder. Do not delete the other directories.
Step3 Open and extract the Zip file to your USB key
Open up the zip file you have just downloaded. Extract all files to the root directory of your USB
key. Once the extraction is complete check that a new Firmware directory has appeared under
the AllenHeathGLD folder on your USB key. You may need to refresh the AllenHeathGLD folder
to see this.
Note: Do not change the folder name or browse inside the Firmware folder as doing this may
cause firmware corruption. Attempting to navigate or open files within this directory may cause
your Operating System to leave behind temporary files which can invalidate your firmware.
Step4 Safely remove the USB key from your computer
Click on the ‘safely remove hardware’ icon, in the bottom right of your screen to safely remove
your USB key.
Step5 Plug the key into a USB port on the GLD
Plug your USB key into either one of the USB ports on the GLD-80. Go to the Setup / Utility /
Firmware screen and touch Update. This will then detect your USB key and validate the
firmware contents.
Step6 Perform the update
Touch the Update button. Do not interrupt this process. When the firmware has been
successfully installed, touch the Reboot button. The GLD will reboot with the new firmware
installed. Any AudioRacks currently connected or connected later to the GLD-80 will have their
firmware automatically updated by the GLD-80 during their boot process.
Step7 Recall your settings
Recall a Template Show or the User Show you saved before the update to restore your settings.
Go to the Setup / Utility / Firmware screen to check
the current firmware version of running on the GLD.
Go to www.allen-heath.com to check the latest version
of GLD firmware available for download.
We recommend you check the Allen & Heath web site
regularly and keep your console updated with the
latest firmware.
