Troubleshooting

The 558 Multi Channel Power Amplifier includes a thermal shutdown, which mutes the output if the amplifier becomes too hot. The Standby LED will also become red.

Leave the amplifier for a few minutes to cool down, the Standby LED will turn green and the sound will come back on.

The 558 Multi Channel Power Amplifier also includes a power circuit breaker to protect the loudspeakers. This is also triggered if the mains supply is interrupted.

Check the system for the cause of the cut out.

Switch off, wait 5 seconds, then switch on to reset the power.
