This LED will light in amber

when the unit is in the Standby mode to signal that 
the unit is ready to be turned on. When the unit is
turned on, the indicator will briefly turn red, and then
change to blue. A red indicator during normal 
operation means that the unit is in the Protect mode,
and should be turned off and then checked for a 
possible speaker-wire short circuit.
