Troubleshooting
Incorrect operation is sometimes mistaken for malfunction. If problems occur, use this section for troubleshooting information. If problems persist, contact your authorized Mark Levinson dealer.
1.Examine the power cord to ensure that it is connected to both the rear panel connector of the amplifier and an electrical outlet.
2.Make sure the amplifier is powered on with the Power switch.
3.Make sure the amplifier is not in Standby mode. The front panel LED should be at full brightness.
4.Examine the electrical circuit breaker to ensure that power
is being supplied to the electrical outlet to which the amplifier is connected.
5.Verify that the voltage rating on the rear panel of the amplifier matches the voltage rating of the electrical outlet. If the voltages do not match, no power is sent to the outputs of the amplifier.
1.Make sure that the source device is powered on, playing audio, and set to the right output connector.
2.Examine cables to ensure a solid connection between the amplifier and associated components.
3.Make sure the amplifier's output connectors are connected to operational loudspeakers.
4.Ensure that the amplifier is not in a fault condition. When the amplifier experiences a fault, the output is muted and the Status
LED on the front panel blinks in a rapid pattern, indicating:
