Operating Guide
• You can have as many files on the USB thumb drive as you want, but only the first five valid files for
the device are displayed.
• The files must be named stellar_pre_v#.#.#.bin. For example, stellar_pre_v2.4.1.bin.
• You can have other bin files for other products on this thumb drive (for example, stellar_dac_
v2.1.2.bin). Only files that start with "stellar_pre_" will be loaded by the Stellar Gold Preamp.
WARNING: In the past, you would update a unit by copying an "image.bin" file to the thumb drive. This
method still works to automatically update a unit after a reboot (you do not need to go through the
menus to use the image.bin file). The image.bin file takes precedence over the stellar_bin_xxx.bin files. It
is recommended to NOT have an image.bin file on the thumb drive if you are using the stellar_pre_xxx.
bin files and the System | FW Update method to update files.
