Problem: The protection LED stays on and the amplifier doesn't work.

1. Check that the nominal impedance of the line of speakers connected to the power outputs is not lower than the minimum allowed as indicated in the user manual.
2. Make sure that the lines of speakers are correctly connected to the power outputs and that there are no short circuits.
3. Check that the air vents are not obstructed and that the amplifier has the necessary space at the front and back for properly conveying the flow of air for cooling.
4. Check that the power mains supplies a voltage level that falls within the admissible range (207 VAC - 253 VAC).
