What to do if the JBL SA550 Classic Amplifier sound cuts out unexpectedly?

  If your JBL Amplifier's sound cuts out unexpectedly, it might be in protection mode. The front panel LED indicates the fault type: * FLASHING BLUE: The internal temperature of the unit reached an unsafe level. Allow the amplifier to cool. * FLASHING ORANGE: The amplifier detected an overload (DC offset). * FLASHING RED: The amplifier detected a speaker short circuit. Inspect all the speaker cables to make sure none of them are shorted together. This fault is more common when exposed wires are being used to make speaker connections. In protection mode, the amplifier will turn itself off and power to the speakers will be removed. To continue using the amplifier, the fault must be treated, and the amplifier must be turned OFF then back ON from the power switch on the rear panel.

How to fix hum on the analogue input of my JBL SA550 Classic?

  Randall HicksAug 22, 2025
  To address hum on the analogue input of your JBL Amplifier, ensure all cables are making a good connection. Try disconnecting the input cable and plug it fully in again after turning the power off. If the hum stops when the source is disconnected, the problem is most likely to be in the cable or the source device to which it is connected.
