Troubleshooting
The LED located on the front of the unit indi-
cates the following states of operation.
If the LED is lit solid blue and there is no sound, do 
the following: 
„
Check that the unit is receiving an analog sig-
nal or valid digital signal.
„
Check the temperature of the rear metal 
panel. If it is hot, turn the unit off for a mini-
mum of five minutes to allow it to cool. When 
cool, turn the unit on and check for normal op-
eration. If necessary, relocate the unit to ensure 
adequate ventilation. 
If the thermal shutdown activates a second 
time, contact M-Audio customer service. 
If the LED is unlit and there is no sound: 
„
Check fuse and power connection. If the fuse 
is intact and the power connection is good, but 
the LED remains unlit with no sound, contact 
M-Audio customer service.
