If you want to use the speakers as stand alone after performing a GLM calibration, you need to store the settings in the speakers and disconnect them from the USB adapter. Here is how it is done:
- Make sure the monitors have the "STORED" DIP switch in "ON" position (8330 has it as default)
- Go to the "Group" menu in GLM
- Choose "Store Group Settings"
- Set the Startup Level, Standalone Max Level, ISS settings and Input Mode
- Press Store and Close
- Confirm settings
After this procedure the USB adapter is disconnected and every time you turn on your speakers the calibration data stored in the speakers will be loaded from their internal memory. Once you connect GLM with the USB adapter, the stored settings will be overidden with the setup you at that moment have active in the GLM software. Then again, when you disconnect the GLM (disconnect the CAT cable from the USB adapter going to the first speaker in your setup, notice that the CAT cables connected in between the other speakers can be left untouched) the stored settings will be taken in use, once you have turned off the speakers and then back on.
