Install the GLD Editor (same version as the Firmware on your GLD, 1.6 is the latest).
Pick your mixer when you first start the program (GLD-80 or -112).
Click the connection button and enter your GLD mixer’s IP address.
Choose whether to connect to the mixer and loading the current GLD Editor settings onto the mixer (generally not a good idea) or loading the current Mixer setup on the GLD Editor (preferred).
If you want to load a setup from your GLD Editor onto the mixer, it’s best to save that as a show file in GLD Editor, connect to the mixer importing the current mixer setup, and then load the showfile to the mixer if desired. This keeps you out of trouble by accidentally overwriting the setup on the mixer when connecting.
A&H has some great GLD videos on their Youtube Channel.
Hope this helps,
