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.
