Loading files
To load the files onto the DSU500, you will need the following:
DSU500
USB to mini USB lead (Golding Audio can provide this)
Computer
ADPCM audio files to put onto the DSU500
The DSU500 will appear as another hard disc drive when connected to the computer. Use standard
drag and drop or cut and paste commands to move files between the computer and the DSU500.
Backing up the DSU500
The DSU500 will be supplied pre-programmed with four test audio files as well as the ‘INIT.txt’ and
‘DSU500.hex’ files.
Please make a backup of these files before loading your own files by following these instructions:
1) Create a folder on your computer named ‘DSU500 backup’.
2) Connect the USB lead to the computer and to the DSU500. The RED status LED should be lit steady.
3) Your computer will automatically load a mass storage driver for the DSU500.
4) Navigate to the drive named DSU500 V1.0 (version number will vary)
5) You should now see the six files listed above. Select all six and copy them to the folder made earlier
as a backup.
You should now select the audio files (.wav) on the DSU500 and delete them before copying your own
files onto the DSU500.
Ensure that the audio files that you wish to load are named with the first three characters as numbers
to indicate to the DSU500 which trip input will trigger them.
Example:
Trip input
Audio file
1
001 Track1.wav
2
002 Canon.wav
3
003 Fire .wav
4
004 dog.wav
As you can see, the first three characters must always be a three digit number but the rest of the file
name can be whatever you like. The extension must be ‘.wav’
The audio files MUST be encoded as Microsoft ADPCM (4 bit) in mono only and with a sample rate of
either 8KHz, 16KHz, 32KHz, 44.1KHz or 48KHz. No other formats will work.
Either copy and paste or drag and drop your new audio files onto the DSU500.
The play LED (blue) will light while the DSU memory is being programmed.
Wait for the files to copy over to the DSU500 and check that the blue play LED has gone out.
Do not disconnect the DSU500 while the play LED is lit during loading and for 5
seconds after the LED has gone off.
If you need to alter the INIT.txt file to enable one shot trips or normally closed trips etc, it is best to
make a copy of the ‘init.txt’ file located in your backup directory and save it with a different name such
as: ‘INIT sfx1.txt’ so that you maintain a copy on your PC.
The first four characters must be ‘INIT’ and the extension must be .txt. Delete the current file on the
DSU500 and then copy over the new one with the modified name.
