On the front panel of the amplifier is a USB Type A port which can transfer files either direction between a USB flash drive and the amplifier. These files can be of two types:
Preset
A Preset file contains amplifier configuration settings.
Device
A Device file, contains all presets and the current amplifier configuration settings.
These files cane be created either from the front panel as outlined below or through the System Architect software. In the System Architect software the files can be created either from the main application File menu or through the File menu on the product control panel.
When you plug in the drive, the amplifier defaults to a file-exchange mode.
It is highly recommended that you do not pass audio through the amplifier while doing file transfers to protect your speakers.
Then you can load or save individual files. No computer is needed for this file transfer.
The file must reside in the flash-drive root (top-level) directory.
Plug the flash drive into the amplifier’s USB port on the front panel.
The screen asks if you want to load or save a file. Press the left encoder to LOAD a file.
The screen asks whether you want to load a device file or preset file. Press the left Encoder to load a device file, or press the right Encoder to load a preset file.
The screen says “Select File to Load.” Turn an encoder to select the file. Turn the encoder to view the files; press the encoder to select. Note: You can’t explore folders or subfolders.
The amplifier loads the file into its memory and displays the Eject Menu. If you are loading a preset file the menu will ask where the preset should be stored.
To continue with more transfers, press the right encoder.
After pressing the left encoder on the Eject Menu, unplug the flash drive. The amp is unmuted and returns to the determined state.
If desired, recall the preset through the front panel or the software.
Plug the flash drive into the amplifier’s USB port on the front panel.
The amplifier goes into “File Mode” and is muted.
The front panel asks if you want to load or save a file. Press the right encoder to select SAVE.
The screen will ask whether you want to save a device file or preset file. Press the left encoder to save a device file, or press the right encoder to save a preset file.
If you chose to save a preset file, the screen says “Select Preset to Save.”
The screen shows the preset files in the amplifier’s memory. Turn an Encoder to view the files; press the Encoder to select.
The amplifier’s Preset file will be saved to a default filename in the flash-drive root directory. If the default filename already exists, a number will be appended to the end of the filename.
You will see the Eject Menu. To stop the transfers, press the left Encoder.
To continue with more transfers, press the right Encoder. Unplug the drive when finished.
After pressing the left encoder on the Eject Menu, unplug the flash drive. The amp is unmuted and returns to the determined state.
