About the CLoader Utility:
When you download System Architect from the web, or get it from a CD, the CLoader Utility will be included.
The CLoader is a very small and simple program that is used to load new firmware into a USB enabled
amplifier. It is intended only to be used in instances where the firmware can not be updated using System
Architect. Please read the included pdf file for more detailed instructions about how to use CLoader.
About the amplifier “Diagnostic Mode”
How to enter diagnostic mode?
After the amplifier has booted up, hold down all three front panel buttons for three seconds or until the LCD
display changes. This puts the amplifier in a self diagnostic mode. It is only to be used for troubleshooting and
setup. Once in this mode, you may use the UP and DOWN buttons to navigate thru several screens. The front
panel LED’s are NOT updated in diagnostic mode!

Fan Mode: read only
o
“ FAN HI ” default mode. Turn on at 53C. Should not turn on at idle.
o “ FAN LO ” sensitive mode. Turn on at 43C (changed to 33C in 1.1.5.5).
o
“ FAN ON ” Fan locked on full time.
To exit this mode, press the Select button or power cycle the amplifier.
How to use the different fan modes?
Under normal use, the default “FAN HI” mode should work just fine. If however, you want the fan to
come on sooner at a lower temperature you can use the more sensitive “FAN LO” mode.
If you really like to hear that fan you can lock the fan to full speed at all times. Be aware, that by
locking the fan on full speed can have negative affects. Because this amplifier does not have a filter, more dust
and dirt will be pulled thru the amplifier than normally would if the fan was allowed to turn off! This results in
the amplifier getting dirty faster and when devices and heatsinks are covered in dirt it is more difficult for them
to dissipate heat. Use this mode with caution!
How do I select the different fan modes?
Hold down the “Sel/Enter” button while the amplifier is powering up. This will toggle the amp between “FAN
ON” full time fan and “FAN LO/HI” whichever is selected LO or HI.
Hold down the “Next/Down” button while the amplifier is powering up. This will toggle the amp between
“FAN HI” and “FAN LO” modes.
