4.4 File Transfer Via the USB Port
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:
A Preset file , which contains amplifier DSP settings for a specific loudspeaker/
amplifier configuration.
A Device file , which contain all 50 presets and the current amplifier DSP settings.
When you plug in the drive, the amplfiier defaults to a file-exchange mode and is
muted. Then you can load or save individual files. No computer is needed for this file
transfer.
How to transfer a file from a USB flash drive to the amplifier:
1. The file must reside in the flash-drive root (top-level) directory.
2. Plug the flash drive into the amplifier’s USB port on the front panel.
3. The screen asks if you want to load or save a file. Press the left Encoder to LOAD a
file.
4. 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.
5. The screen says “Select File to Load.” Turn an Encoder to select the file.
6. If you are loading a preset, the front panel shows the acceptable files in the flash
drive root directory. Turn the Encoder to view the files; press the Encoder to select.
Note: You can’t explore folders or subfolders.
7. The amplifier loads the file into its memory and displays the Eject Menu. To stop
the transfers, press the left Encoder. To continue with more transfers, press the right
Encoder.
8. Unplug the flash drive. The amp is unmuted and returns to the determined state.
9. If desired, recall the preset following the procedures in Sections 4.3.2 and 4.3.3.
